NEW YORK, December 31, 2025, 3:29 PM ET — Regular session
- Oklo Inc. shares fell about 0.8% in afternoon trade, tracking a third straight session of declines.
- SEC filings showed CEO Jacob DeWitte and COO Caroline Cochran shifted about 15.4 million shares into family trusts at $0.
- Traders are watching for signs of further share supply and for updates tied to the company’s U.S. nuclear licensing path.
Oklo Inc. shares slipped on Wednesday after regulatory filings showed the nuclear startup’s top executives shifted large blocks of stock into family and estate-planning trusts.
The disclosures matter because Oklo’s shares have been volatile, and trading has often been sensitive to insider activity and potential dilution at early-stage companies that are still working toward commercial deployment.
They also land as investors reassess the pace of U.S. nuclear buildout and the long approval timelines that can make or break project schedules for advanced reactor developers.
Oklo shares were down about 0.8% at $71.08 in afternoon trading.
Chief Executive Jacob DeWitte reported transferring 7,851,901 shares of Class A common stock to the Jacob DeWitte Family Trust on Dec. 24 for no consideration, while remaining the beneficial owner as trustee, a Form 4 filing showed.
Chief Operating Officer Caroline Cochran disclosed a similar estate-planning reshuffle, including a transfer of 7,583,085 shares to the Caroline DeWitte Family Trust for no consideration, her own Form 4 showed.
Form 4 is the document corporate insiders file with the U.S. Securities and Exchange Commission to disclose share transactions. The filings did not report open-market sales tied to the transfers.
The forms also referenced grantor retained annuity trusts, or GRATs — an estate-planning vehicle that can shift future appreciation of an asset to beneficiaries. Both filings indicated blocks of 1,000,000 shares were contributed to GRAT structures on the same day.
Oklo’s stock has been under pressure for several sessions; it fell 3.7% on Monday and 3.3% on Tuesday, according to 1 .
Investors have also been alert to supply risk after Oklo set up an “at-the-market” program — a structure that lets a company sell newly issued shares into the market from time to time through banks — for up to $1.5 billion earlier this month, a prospectus supplement showed.
Beyond ownership mechanics, licensing remains the core catalyst. “Regulatory execution is emerging as one of the most important gating factors,” wrote Nilanjan Choudhury at Zacks Investment Research in a 2 .
That note highlighted Oklo’s plan to pursue a combined license pathway at the U.S. Nuclear Regulatory Commission — a single application that bundles construction and operating approvals, rather than the traditional two-step process.
Other U.S.-listed nuclear developers, including NuScale Power and Nano Nuclear Energy, have also traded with sharp swings as investors weigh funding needs against the pace of regulatory decisions, a dynamic that has reshaped the sector’s risk profile.
Sector interest has stayed elevated as utilities and policymakers respond to rising electricity demand tied to data centers and electrification, including this week’s move by Duke Energy to seek an early site permit from the NRC for a potential nuclear project, Reuters reported here.
For Oklo, traders are watching whether the stock holds above the $70 area after repeated tests this week, and whether further filings point to additional share movements that could loosen the float in early 2026.
