Alternatives to TerraPower
Since you can't invest in TerraPower directly, here are three publicly traded companies similar to TerraPower that you can invest in.
Cameco
Cameco (CCJ -0.90%) is a Canada-based company that's one of the top publicly traded uranium producers in the world. Nuclear power plants use a process called nuclear fission, where atoms are split apart to release a large amount of energy. A type of uranium called U-235 is commonly used by nuclear plants because its atoms are easily split apart.
As demand for nuclear energy surges, long-term uranium contract prices reached levels not seen since 2008, Reuters reported in 2024. Cameco, which has extensive reserves and focuses on long-term contracts to supply uranium and fuel services directly to nuclear facilities, will likely continue to benefit from the growing demand for nuclear energy.
Oklo
Oklo (OKLO +0.73%) is a nuclear power company that went public in May 2024 via a special purpose acquisition company (SPAC), raising more than $300 million. The company has received backing from OpenAI CEO and co-founder Sam Altman, who served as Oklo's board chairman until mid-2025. Oklo seeks to build scalable nuclear power facilities and plans to start construction on its first small modular reactor in 2027 at the Idaho National Laboratory.
Investing in Oklo is a gamble, though, since the company has yet to generate revenue or break ground on projects. Plus, SPACs are inherently risky since they're essentially "blank check" companies that often lack transparency. Any investment in Oklo should be considered speculative.
Constellation Energy
Constellation Energy (CEG +0.48%): Constellation Energy provides a diversified mix of energy products and is the largest operator of nuclear power plants in the U.S. by capacity. The Baltimore-based company is seeking to build small modular reactors for its existing sites that could help power data centers and other large industrial customers.
Constellation Energy saw its stock soar since the start of 2024 and is forecasting strong earnings growth as demand for nuclear energy is expected to keep climbing. With its strong financial outlook, the company has boosted its modest dividend and repurchased about $2.4 billion of its common stock through the second quarter of 2025.
