Oklo Inc. (NYSE: OKLO) is an advanced nuclear fission power company that entered the public markets through a de-SPAC merger with AltC Acquisition Corp, a blank-check company that completed its initial public offering in 2021. AltC Acquisition Corp was sponsored by AltC Partners LLC, with OpenAI chief executive Sam Altman serving as chairman, and targeted opportunities in the technology and clean-energy sectors. The S-1 registration statement filed in March 2021 laid the foundation for the SPAC's capital raise before it identified Oklo as its combination target. The business combination closed in May 2024, with Oklo beginning to trade on the New York Stock Exchange under the OKLO ticker, focusing on the commercialization of compact fission power plants for grid and off-grid applications.
