 Re: Oklo Inc.

Registration Statement on Form S-1

Filed June 20, 2024

File No. 333-280344

To the addressees
set forth above:

This letter sets forth the
response of Oklo Inc. (the “Company,” “we,” “our” and “us”)
to the comments provided by the staff (the “Staff”) of the Division of Corporation Finance of the Securities
and Exchange Commission (the “Commission”) in its letter dated July 15, 2024 (the “Comment
Letter”) relating to the Company’s Registration Statement on Form S-1 (the “Form S-1”),
filed on June 20, 2024. Concurrently with its submission of this letter to the Staff, the Company has filed an amendment to the Form S-1
(the “Amended Form S-1”) with the Commission through its EDGAR system.

For your convenience, we have
reproduced the Staff’s comments exactly as set forth in the Comment Letter in bold and italics below, and set forth below each such
comment is the Company’s response. Page numbers and captions referenced in the responses refer to the Amended Form S-1
unless otherwise stated.

Form S-1 filed June 20, 2024

Cover Page

 1. We note the significant number of redemptions of your Class A Common Stock in connection with
your extension proxy and business combination and that the shares being registered for resale will constitute a considerable percentage
of your public float. We also note that some of the shares being registered for resale were purchased by the selling securityholders for
prices considerably below the current market price of the Class A Common Stock. Highlight the significant negative impact sales of
shares on this registration statement could have on the public trading price of the Class A Common Stock.

Response:
The Company acknowledges the Staff’s comment and has revised the disclosure on the prospectus cover page and pages 72
and 73 of the Amended Form S-1.

Management's Discussion and Analysis of Financial Condition and
Results of Operations, page 73

 2. We note your disclosure on page 37 that you will likely need additional capital from external
sources and may seek to raise capital through private or public equity or debt financings or through other sources of financing. Please
discuss the effect of this offering on your ability to raise additional capital.

Response:
The Company acknowledges the Staff’s comment and has revised the disclosure on pages 72 and 73  of the Amended Form S-1.

 3. Please expand your discussion here to reflect the fact that this offering involves the potential
sale of a substantial portion of shares for resale and discuss how such sales could impact the market price of your common stock. Your
discussion should highlight the fact that the shares being registered for resale by the selling securityholders collectively represent
approximately 51.1% of your outstanding shares and that your Sponsor and Chief Executive Officer, beneficial owners of 11% and 18% of
your outstanding shares, respectively, will be able to sell all of their shares for so long as the registration statement of which this
prospectus forms a part is available for use.

Response:
The Company acknowledges the Staff’s comment and has revised the disclosure on pages 72 and 73 of the Amended Form S-1.

 General

 4. Revise your prospectus to disclose the price that each selling securityholder paid for the shares
being registered for resale. Highlight any differences in the current trading price, the prices that the Sponsor and selling securityholders
acquired their shares, and the price that the public securityholders acquired their shares. Disclose that while the Sponsor and selling
securityholders may experience a positive rate of return based on the current trading price, the public securityholders may not experience
a similar rate of return on the securities they purchased due to differences in the purchase prices and the current trading price. Please
also disclose the potential profit the selling securityholders will earn based on the current trading price. Lastly, please include appropriate
risk factor disclosure.

Response:
The Company acknowledges the Staff’s comment and has revised the disclosure on the prospectus cover page and page 42
  of the Amended Form S-1.

 5. Include an additional risk factor highlighting the negative pressure potential sales of shares pursuant
to this registration statement could have on the public trading price of your Class A common stock. To illustrate this risk, disclose
the purchase price of the securities being registered for resale and the percentage that these shares currently represent of the total
number of shares outstanding. Also disclose that even though the current trading price is at or below the SPAC IPO price, some private
investors have an incentive to sell because they will still profit on sales because of the lower price that they purchased their shares
than the public investors.

Response:
The Company acknowledges the Staff’s comment and has revised the disclosure on pages 42, 72 and 73 of the Amended
Form S-1.

2.We note your disclosure on page 37 that you will likely need additional capital from
external sources and may seek to raise capital through private or public equity or debt
financings or through other sources of financing. Please discuss the effect of this offering
on your ability to raise additional capital.
3.Please expand your discussion here to reflect the fact that this offering involves the
potential sale of a substantial portion of shares for resale and discuss how such sales could
impact the market price of your common stock. Your discussion should highlight the fact
that the shares being registered for resale by the selling securityholders collectively
represent approximately 51.1% of your outstanding shares and that your Sponsor and
Chief Executive Officer, beneficial owners of 11% and 18% of your outstanding shares,
respectively, will be able to sell all of their shares for so long as the registration statement
of which this prospectus forms a part is available for use.
General
4.Revise your prospectus to disclose the price that each selling securityholder paid for the
shares being registered for resale. Highlight any differences in the current trading price,
the prices that the Sponsor and selling securityholders acquired their shares, and the price
that the public securityholders acquired their shares. Disclose that while the Sponsor and
selling securityholders may experience a positive rate of return based on the current
trading price, the public securityholders may not experience a similar rate of return on the
securities they purchased due to differences in the purchase prices and the current trading
price. Please also disclose the potential profit the selling securityholders will earn based
on the current trading price. Lastly, please include appropriate risk factor disclosure.
5.Include an additional risk factor highlighting the negative pressure potential sales of
shares pursuant to this registration statement could have on the public trading price of
your Class A common stock. To illustrate this risk, disclose the purchase price of the
securities being registered for resale and the percentage that these shares currently
represent of the total number of shares outstanding. Also disclose that even though the
current trading price is at or below the SPAC IPO price, some private investors have an
incentive to sell because they will still profit on sales because of the lower price that they
purchased their shares than the public investors.

Oklo’s Management’s Discussion
and Analysis of Financial Condition and Results of Operations, page 261

 1. Comment:
                                            You disclose on page 3 that references to the “Equinix Option” are
                                            to Equinix’s option expected to be included in the Equinix SAFE, if entered into, to
                                            elect that the Equinix Prepayment Amount be used as consideration for the issuance of shares
                                            of Oklo common stock prior to the consummation of the business combination instead of as
                                            prepayment for the supply of power pursuant to the Equinix LOI. However, you disclose under
                                            “Equinix Prepayment Amount” on page 4 that the Equinix Prepayment Amount
                                            of $25.0 million is for the supply of power by Oklo pursuant to the Equinix LOI. You also
                                            disclose under Recent Developments that “In exchange for the ROFR and other rights
                                            contained in the Equinix LOI, in March 2024, Equinix paid us the Equinix Prepayment
                                            Amount. In connection with the payment amount of the Equinix Prepayment Amount, we may enter
                                            into the Equinix SAFE pursuant to which Equinix would have the right to elect to receive
                                            either (i) 436,779 shares of Oklo common stock, which, at the Closing, would be automatically
                                            surrendered and exchanged for the right to receive the per share Merger Consideration, in
                                            accordance with the trems of the Merger Agreement or (ii) the supply of power at 10%
                                            discount to the most favored nation pricing that we are required to provide Equinix.”
                                            Please address the following:

 · Clarify
                                            whether the “Equinix Option” expected to be included in the Equinix SAFE
                                            can only be used as consideration for the issuance of Oklo common stock instead of
                                            as prepayment for the supply of power pursuant to the Equinix LOI; and

 · Disclose
                                            how AltC and Oklo determined that the Equinix Prepayment Amount should be treated as Permanent
                                            Equity Financing as opposed to a liability or unearned revenue since you disclose on page 4
                                            under “Equinix Prepayment Amount” that the $25.0 million prepayment made
                                            by Equinix to Oklo is for the supply of power by Oklo pursuant to the Equinix LOI and you
                                            disclose under Recent Developments that you could be required to supply power to Equinix
                                            at a discounted price over an extended period at Equinix’s option.

Response: The Company respectfully
acknowledges the SEC’s comment and advises the Staff as follows:

 · Subsequent
                                            to filing the Registration Statement with the Commission, Equinix advised Oklo that it will
                                            not enter into the Equinix SAFE. Accordingly, the Company has removed all references to the
                                            Equinix SAFE and to the Equinix Option throughout Amendment No. 5.

 · “Permitted Equity Financing” is a defined term pursuant to the Merger Agreement. As part
                                                                                                                                                                                                of an arms-length negotiation between the Company and Oklo, the parties have agreed to treat the February 2024 LOI Amount (as
                                                                                                                                                                                                previously defined in the Registration Statement as the Equinix Prepayment Amount) as a Permitted Equity Financing (as defined in
                                                                                                                                                                                                and solely for purposes of its treatment under the Merger Agreement). As a result of treating the February 2024 LOI Amount as a
                                                                                                                                                                                                Permitted Equity Financing under the Merger Agreement, (i) the Equity Value ascribed to Oklo in the transaction is increased by
                                                                                                                                                                                                $25.0 million and (ii) the amount of cash necessary to satisfy the Minimum Cash Condition is reduced by $25.0 million. The
                                                                                                                                                                                                parties came to this agreement because the February 2024 LOI Amount constitutes an additional $25.0 million in cash to Oklo that was
                                                                                                                                                                                                not contemplated at the time the Merger Agreement was entered into in July of 2023 and, therefore, is an additional $25 million
                                                                                                                                                                                                of cash that will be available to the Company upon the consummation of the business combination. We respectfully advise the Staff
                                                                                                                                                                                                that the foregoing agreed upon treatment of the February 2024 LOI Amount under the Merger Agreement is unrelated to the accounting
                                                                                                                                                                                                treatment. As disclosed on page 301 of Amendment No. 5, the February 2024 LOI Amount is treated as a Right of First Refusal
                                                                                                                                                                                                Liability for accounting purposes.

be treated as Permanent Equity Financing as opposed to a liability or unearned
revenue since you disclose on page 4 under "Equinix Prepayment Amount” that the

Background of the Transactions, page 170

 1. Comment: We note your revised disclosure in response to prior comment 3 that, as part of its determination
of a potentially attractive valuation of Oklo for AltC shareholders, AltC evaluated financial guidance published by selected publicly
traded companies, including selected nuclear focused companies and selected renewable independent power producers as well as future financial
forecasts for revenue and EBITDA, published by third-party research analysts (if available) and estimated trading multiples of the selected
publicly traded companies derived from such information, with a focus on EV/EBITDA. We further note you disclose that at the time of the
October 24 Proposal, (a) the selected nuclear focused companies had observed mean EV/EBITDA multiples of 12.4x and 11.8x for
calendar years 2023 and 2024, respectively and (b) the selected renewable independent power producers had observed mean EV/EBITDA
multiples of 18.7x and 15.1x for calendar years 2023 and 2024, respectively. Please disclose these selected publicly traded companies,

analysis of potential run-rate EBITDA generation for Oklo, which implied EV/EBITDA multiples in the mid-single digits. Please disclose
these EV/EBITDA multiples.

Response: The Company respectfully acknowledges

please indicate so in your registration statement. Further, revise the risk factor disclosure
to explicitly clarify that the firms have performed all their obligations to obtain the fee and
therefore is gratuitously waiving the right to be compensated.

Q. What is the amount of net cash per share of AltC common stock
that is being contributed to the Post-Closing Company in the Transactions?, page 19

 2. Comment: We note your disclosure includes the estimated net cash per share of AltC common stock under
a no redemption scenario and maximum redemption scenarios assuming a waiver and no waiver of the minimum cash condition. Revise your disclosure
to show the potential impact of redemptions on the per share value of the shares owned by non-redeeming shareholders by also including
interim redemption levels.

Response: The Company respectfully acknowledges
the Staff’s comment and has revised Amendment No. 1 throughout to reflect additional redemption scenarios, including on pages 15-20, 48-52, 112-117 and 147-152 of
Amendment No. 1.

Q. How do the Sponsor and the Insiders intend to vote on the proposals?,
page 24

 3. Comment: We note that certain shareholders agreed to waive their redemption rights. Please describe
any consideration provided in exchange for this agreement.

Response: The Company acknowledges the
Staff’s comment and respectfully confirms that pursuant to the Sponsor Agreement, the Sponsor and the Insiders agreed to waive their
redemption rights without any separate consideration paid in connection with providing such waiver. The Company has incorporated this
clarification on pages 23, 56 and 137 of Amendment No. 1.

Summary of the Proxy Statement/Prospectus/Consent Solicitation Statement,
page 30

 4. Comment: Revise your disclosure to include the source for your statement that "global demand for
reliable, clean energy is growing rapidly, with 63% of Fortune Global companies publicly committing to emissions reductions by 2050 and
an expected $2 trillion annual spend on new clean power generation globally by 2030" and provide support for your statement that
 "Oklo is a leader in the nuclear industry in the development of fuel recycling" or revise to characterize as your belief.

Response: The Company respectfully acknowledges
the Staff’s comment and has revised its disclosure on pages 13-14, 31, 240 and 253 of Amendment No. 1.

Impact of the Business Combination on Our Public Float, page 46

    Securities and Exchange Commission

    November 13,

 5. Comment: It appears that underwriting fees remain constant and are not adjusted based on redemptions.
Revise your disclosure here to include interim redemption levels and to disclose the effective underwriting fee on a percentage basis
for shares at each redemption level presented in your sensitivity analysis related to dilution.

Response: The Company respectfully acknowledges
the Staff’s comment and has amended its disclosure on pages 52-53 and 152 of Amendment No. 1.

Interests of Certain AltC Persons in the Business Combination, page 52

 6. Comment: Please highlight the risk that the sponsor will benefit from the completion of a business
combination and may be incentivized to complete an acquisition of a less favorable target company or on terms less favorable to shareholders
rather than liquidate.

Response: The Company respectfully acknowledges
the Staff’s comment and has amended its disclosure on pages 57, 107 and 192-193 of Amendment No. 1.

 7. Comment: Please clarify if the sponsor and its affiliates can earn a positive rate of return on their
investment, even if other SPAC shareholders experience a negative rate of return in the post-business combination company.

Response: The Company respectfully acknowledges
the Staff’s comment and has revised its disclosure on pages 57, 107 and 193 of Amendment No. 1.

 8. Comment: Your charter waived the corporate opportunities doctrine. Please address this potential conflict
of interest and whether it impacted your search for an acquisition target.

Response: The Company respectfully acknowledges
the Staff’s comment and has revised its disclosure on pages 57-58, 107 and 193 of Amendment No. 1.

Cautionary Note Regarding Forward-Looking Statements, page 66

 9. Comment: We note your reliance upon the safe harbor provided by the U.S. Private Securities Litigation
Reform Act of 1995 for forward-looking statements. However, it is unclear whether this safe harbor is available for forward-looking statements
made in connection with a de-SPAC transaction. Therefore, please qualify your assertion with a statement indicating that there is uncertainty
as to the availability of the safe harbor in connection with a de-SPAC transaction.

Response: The Company respectfully acknowledges
the Staff’s comment and has revised its disclosure on page 72 of Amendment No. 1.

Risk Factors

Risks Related to AltC and the Business Combination, page 102

    Securities and Exchange Commission

    November 13,
    2023

    Page 4

 10. Comment: Disclose the material risks to unaffiliated investors presented by taking the company public
through a merger rather than an underwritten offering. These risks could include the absence of due diligence conducted by an underwriter
that would be subject to liability for any material misstatements or omissions in a registration statement.

Response:
The Company respectfully acknowledges the Staff’s comment and has revised its disclosure on page 112 of Amendment No. 1 to discuss risks presented by taking the Company public through a merger rather than an underwritten offering.
Further, the Company advises the Staff that Citigroup Global Markets Inc., in its capacity as capital markets advisor to the Company,
has conducted due diligence on Oklo and AltC in connection with the business combination in a matter that is substantially consistent
with the due diligence it would typically expect to perform in an underwritten offering (it being understood that what is “substantially
consistent” may vary from situation to situation). Accordingly, we respectfully believe that no disclosure of risks regarding the
absence of due diligence is appropriate. The Company understands that the capital markets advisor does not acknowledge that it is an
underwriter or has potential liability under the U.S. securities law as an underwriter.

Regulatory delays could cause us to be unable
to consummate the business combination, page 118

 11. Comment: We note your disclosure stating that you do not believe that either you or your sponsor constitute,
are controlled by or have substantial ties with, a “foreign person” under CFIUS rules and regulations. Please also tell
us whether anyone or any entity associated with or otherwise involved in the transaction, is, is controlled by, or has substantial ties
with a non-U.S. person. If so, also include risk factor disclosure that addresses how this fact could impact your ability to complete
your initial business combination. For instance, discuss the risk to investors that you may not be able to complete an initial business
combination with a U.S. target company should the transaction be subject to review by a U.S. government entity, such as CFIUS, or ultimately
prohibited. Further, disclose that the time necessary for government review of the transaction or a decision to prohibit the transaction
could prevent you from completing an initial business combination and require you to liquidate. Disclose the consequences of liquidation
to investors, such as the losses of the investment opportunity in a target company, any price appreciation in the combined company, and
the warrants, which would expire worthless.

Response: The Company respectfully acknowledges
the Staff's comment and confirms that neither AltC, the Sponsor, or anyone or any entity associated with or otherwise involved in the
Transactions is, is controlled by, or has substantial ties with a non-U.S. person. The Company has incorporated a risk factor concerning
this disclosure on pages 126-127 of Amendment No. 1.

Background of the Transactions, page 160

 12. Comment: We note that Citigroup Global Markets Inc. performed additional services after the IPO and
part of the IPO underwriting fee was deferred and conditioned on completion of a business combination. Please describe the services Citigroup
provided as your capital markets advisor after the completion of your initial public offering and the associated fees with such engagement.
Also, quantify the aggregate fees payable to Citigroup that are contingent on completion of the business combination.

Response: The Company respectfully acknowledges
the Staff’s comment and has revised its disclosure on page 171 of Amendment No. 1.

    Securities and Exchange Commission

    November 13,
    2023

    Page 5

 13. Comment: You disclose that representatives of AltC and the sponsor evaluated over a dozen potential
targets and in connection with evaluating such opportunities, representatives conducted discussions and commenced due diligence on several
potential target opportunities. Please expand your discussion in this section to describe the process utilized to evaluate the other potential
targets. Please discuss the information gathered, how and by whom it was evaluated and whether any negotiations occurred. Your disclosure
should clearly describe the reasons you did not further consider pursuing any alternative targets.

Response: The Company respectfully acknowledges
the Staff’s comment and has revised its disclosure on pages 166-167 of Amendment No. 1.

 14. Comment: You disclose that the pre-money equity value for Oklo included in the October 24 Proposal
was based on “AltC’s preliminary review of Oklo’s forecasted unit economics as compared to publicly available financial
information for selected publicly traded companies, including companies in the nuclear energy industry that had recently engaged in go
public transactions.” Please revise your disclosure to summarize the financial information for selected publicly traded companies
that was reviewed by AltC and describe how this information was applied to determine Oklo’s pre-money equity value of $750 million
to $850 million.

Response: The Company respectfully acknowledges
the Staff’s comment and has revised its disclosure on pages 167-168 of Amendment No. 1.

 15. Comment: You state that the October 24 Proposal provided that the consideration to be paid would
consist entirely of shares of AltC Class A common stock, included a minimum cash condition and contemplated earnout consideration
that would be based on the performance of AltC Class A common stock. Please revise to include additional details to explain how these
terms originated and the negotiations surrounding them.

Response: The Company respectfully acknowledges
the Staff’s comment and has revised its disclosure on pages 167-168 of Amendment No. 1.

Information About Oklo, page 252

 16. Comment: We note your disclosure that you do not expect to generate meaningful revenue unless and until
you are able to finalize development of and commercialize the Aurora product line, and you may not be able to do so on your anticipated
timetable, if at all. We also note that your first powerhouse is targeted for deployment in 2026 or 2027. Please revise your disclosure
to describe in more detail your plans for deploying your initial Aurora powerhouse project. Also disclose your plan of operations for
the next twelve months including the anticipated timeline and expenditures for these events.

Response: The Company respectfully acknowledges
the Staff’s comment and has revised its disclosure on pages 255-256 of Amendment No. 1.

Response: The Company respectfully acknowledges

General

 18. Comment: We note that on October 5, 2023, stockholders approved a charter proposal to extend the
date by which the Company has to consummate a business combination from October 12, 2023 to July 12, 2024. Please update your
disclosure throughout your registration statement accordingly.

Response: The Company respectfully
acknowledges the Staff’s comment and has revised its disclosure on pages 2, 25, 40, 43, 56, 64, 108, 109, 110, 159, 162, 173,
191, 192, 226, 227, 238, 285, F-61 and F-71 of Amendment No. 1.

 19. Comment: We note that Citigroup was an underwriter for the initial public offering of the SPAC and
has acted as your capital markets advisor in connection with the business combination. Please tell us, with a view to disclosure, whether
you have received notice, or any other indication, from Citigroup or any other firm engaged in connection with your initial public offering
that it will cease involvement in your transaction and how that may impact your deal or the deferred underwriting compensation owed for
the SPAC’s initial public offering.

Response: The Company has received
formal notice from each of BofA Securities, Inc., Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC noting that
such party is not involved with the business combination and waiving its right to its portion of the deferred

Ladies and Gentlemen:

On behalf of our client, AltC Acquisition Corp.,
a Delaware corporation (the “Company”), we submit this letter in response to the comment of the staff (the “Staff”)
of the Securities and Exchange Commission (the “Commission”) contained in its letter dated May 14, 2021, relating
to the Registration Statement on Form S-1 of the Company (File No. 333-254263) (the “Registration Statement”)

to the Registration Statement. The changes reflected in Amendment No. 2 include other changes intended to update, clarify and render
more complete the information set forth therein.

Set forth below is the Company’s response
to the Staff’s comment. For ease of reference, the Staff’s comment is reproduced below in bold and is followed by the Company’s
response.

Amendment No. 1 to Registration Statement on Form S-1

Use of Proceeds, page 64

1. In the table, please revise to present the correct amounts for “Proceeds after estimated offering expenses,” “Held
in trust account,” and “Not held in trust account” that coincide with your revised offering.

Securities and Exchange Commission

June 4, 2021

Page 2

  The Company acknowledges the Staff’s comment and has
revised the disclosure on page 64 accordingly.

Dilution, page 68

2. It appears that footnote (1) on page 69 should reference $14,000,000 instead of $17,500,000 of deferred underwriting
commissions. Please revise or advise.

  The Company acknowledges the Staff’s comment and has
revised the disclosure on page 68 accordingly.

Principal Stockholders, page 119

3. You state on page 119 and throughout that, upon the completion of this offering, your initial stockholders will beneficially
own 20.0% of the then issued and outstanding shares of your common stock. We note the revised principal stockholders table indicates that
your sponsor and Michael Klein will own 22% of your outstanding common shares after the offering. Please tell us the basis for this discrepancy
or revise, as appropriate.

  The Company acknowledges the Staff’s comment and respectfully
advises the Staff that references to 20% are exclusive of the private placement shares and references to 22% are inclusive of the private
placement shares. The Company respectfully advises the Staff that it revised the disclosure on page 120 and throughout to accurately
describe the distinction.

Statement of Operations, page F-4

4. Please update the number of weighted average shares outstanding and related footnote (1) disclosure to reflect both the pending
surrender of 17,250,000 Class B shares and forfeiture of an additional 1,500,000 shares in connection with your offering. Similar
concerns apply with respect to footnote (1) of the Balance Sheets on page F-3 and the Statements of Changes in Stockholder’s
Equity on page F-5.

  The Company acknowledges the Staff’s comment and has
revised the disclosure on pages F-3 – F-5 accordingly.

5. We note that the auditor’s consent makes reference to the audit of your financial statements as of and through March 31,
2021 instead of March 4, 2021. Please revise.

  The Company acknowledges the Staff’s comment and has
filed a revised exhibit 23.1.
