Oklo Inc.
Oklo Inc. demonstrates how a SPAC vehicle assembled by a single financier-and-founder dyad can convert a pre-IPO nuclear startup into a publicly traded entity at near-zero redemption while shedding the directors most exposed to conflict-of-interest concerns in the eighteen months following the merger, replacing them with former federal regulators positioned to navigate the same agencies that approve the company's reactors.
Oklo Inc. (NYSE: OKLO) is a Santa Clara-based small modular reactor (SMR) developer that became publicly traded on May 9 2024 through reverse merger with AltC Acquisition Corp, a special purpose acquisition company chaired by financier Michael Klein and co-led by Sam Altman as Chief Executive Officer 12. Klein-affiliated Archimedes Advisor Group LLC ran target sourcing for the combination, and the AltC closing was an acknowledged anomaly: holders of only 710 public shares exercised redemption for 7,457.80 dollars out of approximately 30 million Class A shares outstanding, leaving roughly 306 million dollars in trust and rendering the sponsor's 50 million-dollar PIPE backstop unused 12.
Altman chaired the Oklo Board from October 2015 through May 2024 and remained Chair after the SPAC closing until resigning effective April 22 2025, three months after the January 21 2025 announcement of the Stargate Project, the OpenAI-SoftBank-Oracle-MGX artificial-intelligence infrastructure joint venture 34. The 2026 proxy statement reports that as of April 6 2026 co-founders Jacob DeWitte and Caroline DeWitte each beneficially own 21,159,091 shares (12.16 percent), BlackRock holds 14,419,350 shares (8.29 percent) as the only other 5-percent holder, Klein retains 150,000 shares via M. Klein Associates Inc, and former US Energy Deputy Secretary Daniel B. Poneman holds 37,000 shares 56. No MGX, Mubadala, SoftBank, or Saudi Public Investment Fund position is disclosed in the post-Altman capitalization table 56.
Analysis of the SEC primary-source record indicates the Klein-Altman-Oklo SPAC and the Stargate-MGX joint venture are structurally separate, though press treatment conflated them 7. Examination of the 2025 proxy filings shows Board composition shifting from a tech-financier-anchored directorate (Altman, Klein, original Class III nominee Christopher Wright) to one anchored by former federal regulators, with Wright resigning to become US Secretary of Energy and Poneman appointed March 4 2025 846.
Corporate Structure and SPAC Origin
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.
Anomalous AltC Closing
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.
Measured against contemporaneous SPAC redemption rates, the redemption profile 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. Analysis of the trade timing groups the AltC closing 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 clustered around the January 2025 Stargate window, suggesting the Stargate announcement re-bundled infrastructure activity already in motion rather than initiating it 7.
Sam Altman's Board Tenure and Resignation
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. The timing suggests 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. Analysis indicates it also removed 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.
Post-Altman Beneficial Ownership
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.
Government Nuclear-Policy Intermediation
Examination of the proxy filings shows that during the first half of 2025 Oklo's Board composition shifted from a tech-financier configuration toward one of former federal regulators 84. According to the 2024 S-4/A and 2025 proxy, Christopher Wright, the Liberty Energy Chief Executive Officer and original Class III nominee, 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. Records indicate the shift substituted 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.
Oklo Inc.
Klein-Altman-Oklo and Stargate-MGX Structural Separation
Analysis indicates 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. Records reveal that 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 — shows 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.
Significance to the Investigation
Oklo is a clear test case for the structural-separation finding. Analysis suggests that on press treatment alone it is among the SPAC vehicles most readily confused with a Stargate or MGX-anchored asset, yet the SEC primary-source record shows no such overlap in equity terms 75. Klein recurs as a SPAC sponsor and advisory-fee bridge across the post-2018 financial-intermediation network, and Oklo is among his most visible 2024–2026 sponsor outcomes 910.
Within the Altman-Klein-DeWitte network, records indicate Klein holds a 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. Review of the filings shows Oklo's evolution from a 2015-vintage venture-backed startup to a 2024 SPAC merger to a 2025–2026 former-DOE-anchored issuer compressing 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.

AltC/Oklo merger closed May 9 2024: only 710 public shares redeemed ($7,457.80); ~$306M trust capital retained.
AltC 8-K filed 2024-05-08 (Item 5.07/8.01) reports holders of 710 Class A shares exercised redemption at ~$10.50/share, total redemption $7,457.80; 43,099,811 shares of common stock remained outstanding; ~$306M remained in Trust Account. AltC IPO 2021-07-12 raised $500M gross. Sponsor Commitment up to $50M PIPE backstop at $10/share; backstop NOT triggered (cash above $250M floor). Klein chaired AltC; Altman was AltC CEO. Renamed Oklo Inc. 2024-05-08. Near-zero redemption rate is a SPAC anomaly suggesting non-redemption agreements with anchor holders.
Post-Altman Oklo beneficial ownership: DeWittes 12.16% each (controlling), BlackRock 8.29%, Klein only 150,000 shares; no Mubadala/MGX/SoftBank holding disclosed.
Oklo 2026 DEF 14A (filed 2026-04-21, accession 0001849056-26-000023) reports as of April 6 2026: BlackRock Inc 14,419,350 shares (8.29%) only 5%+ holder; Jacob DeWitte and Caroline DeWitte (married, co-founders) each beneficially own 21,159,091 (12.16%) — concentrated in family trusts and GRATs; Klein holds 150,000 shares via M. Klein Associates Inc; Daniel Poneman (former Centrus CEO + Deputy Energy Secretary 2009-2014) holds 37,000. NO Mubadala, MGX, SoftBank, or PIF disclosed as 5%+ holder. Oklo is NOT a Stargate vehicle in cap table terms — the Klein/Altman/Oklo SPAC is structurally separate from the Stargate JV. Klein chairs Churchill Capital Corp IX, X, XI (active blank checks affiliated with M. Klein Associates Inc, NY corp).

Klein-affiliated Archimedes Advisor Group LLC ran AltC's target sourcing for the Oklo combination.
Final S-4/A (filed 2024-04-15, accession 0001104659-24-047344) discloses Archimedes Advisor Group LLC as 'AltC's strategic advisor and affiliate of Michael Klein, Chairman of the Board of AltC' commenced focused search 2021-2022 for combination targets. AltC IPO 2021-07-12 raised $500M. AltC Sponsor LLC and 'Insiders' (Sam Altman, Michael Klein, Jay Taragin, Frances Frei, Allison Green, Peter Lattman, John L. Thornton) were identified as having interests differing from public stockholders. M. Klein and Company is the related strategic advisory firm Klein founded in 2012.
Sam Altman resigned from Oklo Board effective April 22 2025, three months after the Stargate Project announcement (Jan 21 2025).
Oklo 2025 DEF 14A (filed 2025-04-22, accession 0001628280-25-018885) discloses 'Effective April 22, 2025, Sam Altman resigned from the Board. Mr. Altmans decision to resign was not due to any disagreement with the Company.' Stargate (announced Jan 21 2025) is the OpenAI/SoftBank/Oracle/MGX AI infrastructure JV; Oklo would be a logical SMR power supplier for the Texas data centers, creating a related-party / conflict optic if Altman remained Oklo Chair while OpenAI procures power. Altman had chaired Oklo Board since October 2015. He waived all director compensation while serving (2024 fees $0, stock awards $0). His Oklo equity is below the named-officer disclosure threshold in 2026 — he is no longer in the beneficial ownership table at all.
Government nuclear-policy intermediation pillar at Oklo: Daniel B. Poneman (former DOE Deputy Secretary, former Centrus CEO) joined Oklo Board March 4 2025; Chris Wright resigned to become Energy Secretary 2025.
Sequence: (1) Chris Wright (Liberty Energy CEO; original Oklo Class III nominee per 2024 S-4/A) resigned Oklo Board to become US Energy Secretary in early 2025; (2) March 4 2025 Board appointed Michael Thompson and Daniel B. Poneman (per 2025 DEF 14A); (3) April 22 2025 Altman resigned. Poneman: Centrus Energy CEO 2015-2023 (uranium enrichment); DOE Deputy Secretary 2009-2014 — directly responsible for nuclear infrastructure approvals. The composition shift converts Oklo's board from 'tech-financier-anchored' (Altman/Klein/Wright) to 'former-DOE-anchored' (Poneman + Jansen + Park) just as Wright takes over DOE. Inference: Oklo is positioning for accelerated NRC licensing under a friendly DOE while distancing from Altman to avoid OpenAI-Stargate procurement conflict-of-interest optics.

Seven cross-cutting patterns emerge across the broader network. (1) A regulatory revolving door connects law and consultancy firms to bank-charter approvals in four instances: a three-instance Skadden-or-equivalent-to-OCC-to-implementation pipeline (Brooks 2020 Coinbase-to-OCC-to-Bitfury; Gould 2025 Bitfury/BlackRock/Promontory-to-OCC; Cohen 2025 Skadden-to-OCC-to-Erebor approval, with Cohen's 65-day window the tightest), plus a separate firm-to-OMB-to-Schaerr Jaffe-to-OMB path via Paoletta (2018 and 2025) at OMB, CFPB and OIRA, distinct from the OCC pipeline. (2) Brooks-era interpretive letters #1170, #1174 and #1184 remain operative law and are cited in the Erebor approval letter, so the deregulation framework now scaffolds WLFI/Tahnoon flows. (3) Aryam Investment 1, a Tahnoon vehicle, bought 49% of WLFI for $500M (with $187M to Trump-family entities); G42's Edelman and Xiao were seated without disclosure; MGX deployed $2B of WLFI USD1 to Binance in May 2025. (4) The 'Mubadala unifies' model expanded to three SCFEA sovereign pillars (ADIA, Mubadala and L'IMAD, roughly $300B after the January 2026 consolidation under Khaled bin Mohamed bin Zayed), a regulatory layer (Al Shorafa across ADX, SCA and ADGM as Vice Chair) and a US-listing layer (Kazim as a Nasdaq Inc. director via Borse Dubai), indicating these bridges outlast individual principals. (5) Pre-positioning trades cluster around the January 2025 Stargate window: a Bitfury $53.9M dividend on December 23 2024 (38 days before the Cipher PIPE), the AltC close in May 2024 with an anomalous $7,457.80 redemption out of roughly 30M shares (PIPE backstop not triggered), Crusoe's Abilene construction start in June 2024 (7 months before the Stargate announcement) and SoftBank's full exit from Cipher in Q3 2025, suggesting Stargate largely re-bundled preexisting infrastructure already in motion. (6) Klein-Altman-Oklo and Stargate-MGX are structurally separate at the SEC primary-source level, though press treatment merged them; Altman resigned the Oklo board on April 22 2025, three months after the Stargate announcement. (7) bin Sulayem resigned from DP World on February 13 2026 after the DOJ Epstein release — the first observed visible loss for the Tahnoon network on Epstein-related exposure — while his replacement Kazim maintains and extends US-market access via a Nasdaq Inc. board seat. Several identifications were also corrected: Stéphane resolves to Bertrand G. des Pallières; Antoine Bremner, previously unverified, is likely Christopher Bremner; Compagnie Du Saleve B223232 was incorporated in 2018 and so cannot be the 28 October 2015 entity (likely the closed French SARL #803012046 instead); SKAS is the Saker Aviation Services ticker rather than a partners' acronym; and Hoffenberg's claim that 'Gold shielded Epstein' has no docket support in 1:94-cr-00213.
background (1)
Klein's SPAC pipeline as of 2026: Churchill Capital IX, X, XI (sponsors all affiliates of M. Klein Associates Inc, NY corp); historical: Lucid (PIF-backed, Churchill IV), Clarivate (Churchill I), MultiPlan (Churchill III, subject of Delaware Chancery breach-of-fiduciary-duty SPAC opinion).
Per Oklo 2026 DEF 14A Klein bio: 'Mr. Klein is currently the Chief Executive Officer, President and Chairman of Churchill Capital Corp IX, Churchill Capital Corp. X and Churchill Capital Corp. XI, all three (3) of which are blank check companies whose respective sponsors are affiliates of M. Klein Associates, Inc., a New York corporation (MKA).' Klein is co-founder/Chairman of original Churchill Capital Corp (2018). Churchill I -> Clarivate (May 2019). Churchill III -> MultiPlan (subject of Skadden-tracked first-impression Delaware Chancery SPAC sponsor disclosure ruling). Churchill IV -> Lucid (Saudi PIF anchor; PIF >$1B 2018 pre-SPAC commit; Saudi assembly plant promise). M. Klein and Company LLC = strategic advisory firm Klein founded 2012; advised PIF on multiple SoftBank-PIF transactions per public reporting. Klein on Trilateral Commission. Active SPAC pipeline through 2026 means Klein remains a dominant SPAC sponsor and likely vehicle for future Gulf-state-anchored US public listings.
