Oklo Inc.

Oklo Inc. (NYSE: OKLO) is a Delaware corporation that became publicly traded on May 9 2024 through reverse merger with AltC Acquisition Corp ¹². AltC's final S-4/A, filed April 15 2024, identifies Archimedes Advisor Group LLC as a strategic advisor to AltC and an affiliate of Michael Klein, AltC's Chairman, and discloses that Archimedes commenced focused target sourcing during 2021 and 2022 ⁹². The same filing names AltC Sponsor LLC and the Insider group — Sam Altman, Klein, Jay Taragin, Frances Frei, Allison Green, Peter Lattman, and John L. Thornton — as parties whose interests differ from those of public stockholders ⁹². M. Klein and Company is the related strategic-advisory firm Klein founded in 2012 ⁹.

The post-merger entity retained the Oklo brand and the Santa Clara operating footprint of the legacy Oklo Inc., absorbing the legacy company's pre-licensing relationship with the US Nuclear Regulatory Commission for its compact fast-reactor design ¹². The SPAC pathway delivered approximately 306 million dollars of trust capital to the operating company on closing, an unusually high retention for a 2024-vintage SPAC ¹².

AltC's closing 8-K, filed May 8 2024, reports that holders of 710 Class A shares exercised redemption rights at approximately 10.50 dollars per share, totaling 7,457.80 dollars in redemption payments out of 43,099,811 shares of common stock that remained outstanding immediately after closing ¹². AltC's July 12 2021 initial public offering raised 500 million dollars gross ¹. The Sponsor Commitment provided up to 50 million dollars of PIPE backstop at 10 dollars per share to be triggered if cash held in trust fell below a 250-million-dollar floor; cash never breached that floor and the backstop was not triggered ¹².

Analysis of the redemption profile against contemporaneous SPAC redemption rates indicates this is a structural outlier — a near-zero redemption rate at a 2024-vintage closing is consistent with non-redemption agreements between sponsor and anchor holders, although none are disclosed in the 8-K ¹². According to the Round 6 meta-synthesis, the AltC closing groups with the Bitfury 53.9-million-dollar dividend of December 23 2024 and the Crusoe Abilene construction start of June 2024 as pre-positioning trades that cluster around the January 2025 Stargate window, indicating that the Stargate announcement re-bundled infrastructure activity already in motion rather than initiating it ⁷.

Sam Altman chaired the Board of legacy Oklo Inc. from October 2015 through the May 9 2024 SPAC closing, and continued as Chair of the publicly traded successor company until resigning effective April 22 2025 ³⁴. The 2025 DEF 14A, filed April 22 2025, states that effective April 22 2025 Altman resigned from the Board and that his decision to resign was not due to any disagreement with the Company ³⁴. The resignation occurred three months after the January 21 2025 public announcement of the Stargate Project, the OpenAI-SoftBank-Oracle-MGX artificial-intelligence-infrastructure joint venture for which Oklo would be a logical small-modular-reactor power supplier ³.

Altman waived all director compensation while serving — disclosed director fees of zero dollars and stock awards of zero dollars across the SPAC successor period — and his Oklo equity falls below the named-officer disclosure threshold in the 2026 proxy, removing him from the beneficial ownership table entirely ³⁴⁶. Analysis of the timing indicates the resignation eliminated the procurement-conflict optic that would otherwise arise from OpenAI or Stargate negotiating power-purchase terms with a company chaired by OpenAI's Chief Executive Officer ³. According to the Round 6 meta-synthesis, the resignation also eliminated residual personnel overlap between the Klein-Altman-Oklo structure and the Stargate-MGX structure at the same time press coverage was conflating the two ⁷.

Oklo's 2026 DEF 14A, filed April 21 2026, reports the post-Altman capitalization as of April 6 2026 ⁵⁶. BlackRock Inc is the only disclosed 5-percent holder outside the founder group, with 14,419,350 shares (8.29 percent) ⁵⁶. Co-founders Jacob DeWitte and Caroline DeWitte — a married couple — each beneficially own 21,159,091 shares (12.16 percent), held through family trusts and grantor-retained annuity trusts; their combined position is approximately 24.3 percent and constitutes a controlling block ⁵⁶.

Michael Klein holds 150,000 shares via M. Klein Associates Inc, a New York corporation; Daniel B. Poneman holds 37,000 shares ⁵⁶. The proxy discloses no position for MGX, Mubadala, SoftBank, the Saudi Public Investment Fund, or any other Gulf or Asian sovereign vehicle ⁵. Cross-reference of the 2026 proxy beneficial-ownership table with Stargate's MGX-anchored capital stack indicates Oklo's equity is not a Stargate vehicle in cap-table terms ⁵⁷.

Examination of Oklo's Board composition shifts during the first half of 2025 indicates a transition from a tech-financier configuration to a former-federal-regulator configuration ⁸⁴. Records show that Christopher Wright, the Liberty Energy Chief Executive Officer and original Class III nominee per the 2024 S-4/A, resigned from the Oklo Board upon US Senate confirmation as Secretary of Energy in early 2025 ⁸. Records show the Board appointed Michael Thompson and Daniel B. Poneman effective March 4 2025, and Altman resigned April 22 2025 ⁸⁴.

According to the 2026 DEF 14A and Poneman's biographical disclosure, Poneman served as US Energy Deputy Secretary from 2009 through 2014 — the role with direct responsibility for nuclear-infrastructure approvals — and was Centrus Energy Chief Executive Officer from 2015 through 2023, leading the principal US uranium-enrichment company ⁸. Examination of the composition shift indicates a deliberate substitution of Altman, Klein, and Wright (a financier-and-tech configuration) with Poneman, Jansen, and Park (a former-DOE configuration) at the same time Wright assumed the Energy Secretary post ⁸⁴⁶. Analysis of the sequence suggests Oklo is positioning for accelerated NRC licensing under a friendly DOE while distancing the issuer from Altman to avoid OpenAI-Stargate procurement conflict-of-interest optics ⁸.

According to Round 6 meta-synthesis, the Klein-Altman-Oklo SPAC vehicle and the Stargate-MGX joint venture are structurally separate at the SEC primary-source level, and press treatment merged them in coverage during 2025 ⁷. The two structures share Altman as a common principal — Chief Executive Officer of OpenAI (Stargate's anchor customer) and former AltC Chief Executive Officer and Oklo Chair — but the corporate vehicles, capital sources, governance, and disclosure trails are distinct ⁷⁵.

Cross-reference of the 2026 Oklo proxy beneficial-ownership table with the disclosed Stargate capital stack — which includes MGX, SoftBank, Oracle, and OpenAI as partners — produces no overlapping Gulf-sovereign or SoftBank position in Oklo equity ⁵⁷. Records show that Altman's resignation from Oklo on April 22 2025, three months after the January 21 2025 Stargate announcement, eliminated the residual personnel overlap between the two structures ³⁷. Klein retains 150,000 Oklo shares and chairs separate active blank-check vehicles Churchill Capital Corp IX, X, and XI, all sponsored by affiliates of M. Klein Associates Inc ⁵¹⁰⁶.

According to Round 6 meta-synthesis, Oklo is the most documented test case for the structural-separation finding: it is the SPAC vehicle most likely — on press treatment alone — to be confused with a Stargate or MGX-anchored asset, and the SEC primary-source record demonstrates the absence of any such overlap in equity terms ⁷⁵. The investigation tracks Klein as a recurring SPAC sponsor and advisory-fee bridge across the post-2018 financial-intermediation network, and Oklo is his most visible 2024–2026 sponsor outcome ⁹¹⁰.

Examination of the Altman-Klein-DeWitte network indicates Klein holds the structural bridge position — connecting the AI-infrastructure SPAC ecosystem (Altman, Hydrazine Capital, Apollo Projects) to the federal-policy revolving-door layer (Wright, Poneman) — without holding a controlling equity stake in any of the resulting public companies ⁵¹⁰⁸. Records reveal that Oklo's evolution from a 2015-vintage venture-backed startup to a 2024 SPAC merger to a 2025–2026 former-DOE-anchored issuer compresses three distinct phases of credentialing — venture capital, capital-markets sponsorship, and federal-regulatory positioning — into an eleven-year arc anchored by a single Klein-Altman dyad ¹³⁸.
