Nuclear energy startup Oklo (NYSE: OKLO) has launched a new at-the-market equity program to raise up to $1 billion through fresh share sales, marking another round of dilution for early investors.
The company initiated the ATM program on September 11, a common fundraising mechanism for pre-revenue companies that need consistent access to capital markets.
However, Oklo has turned to this method with notable frequency since going public through a merger with a special purpose acquisition company on May 10, 2024.
At the time of that SPAC merger’s close, Oklo had approximately 122.1 million shares outstanding, a figure that has since grown substantially with each successive fundraising effort.
By June 30, 2026, the share count had climbed to 186 million, and the company subsequently issued another 7.3 million shares under a separate equity program launched in May.
That brings Oklo’s total outstanding share count to roughly 192.3 million, representing a 58% increase from the level recorded when the company first went public.
Shareholders who purchased stock on the first day of trading and held their positions have seen their ownership stake shrink by approximately 37% relative to their original position.
Those investors have not necessarily lost money, however, as Oklo’s share price had risen 311% as of October 12, meaning early buyers are still sitting on substantial gains despite the dilution.
The more immediate concern centers on a sharp and recent decline in Oklo’s stock price, which hit a 52-week low on October 8, complicating the company’s ability to raise capital efficiently.
A lower share price means Oklo must issue more shares to raise the same dollar amount, with the May program having sold around 18 million shares to generate $1 billion, while raising an equivalent sum at the current trading price of approximately $35 per share would require issuing closer to 29 million shares.
That gap illustrates how falling valuations can accelerate dilution, placing additional pressure on existing shareholders with each new funding round the company pursues.
Oklo operates in the advanced nuclear energy sector, an industry that carries significant promise but also substantial commercial and regulatory risk for investors willing to take a long-term view.
