ENTRA1 is a private company that collaborates with NuScale. The lawsuit alleges that NuScale exaggerated ENTRA1's experience and capabilities to investors. The lawsuit is ongoing.As of this writing, NuScale's stock has plunged nearly 30% year to date. Oklo's stock is also down more than 20% in the same time, but it has still increased by 40% over the past 12 months. Both stocks still require a very high level of risk tolerance and a meaningful time horizon. Right now, Oklo is the cleaner bet and winner. It has a long runway and high-profile partners, including Meta Platforms. NuScale had a regulatory lead, but the questions surrounding its legal issues make investing in the company too risky at the moment. If NuScale can beat the allegations with minimal financial and reputational damage, the company could still be quite successful in the coming years.<h2>Should you buy stock in Oklo right now?</h2> Before you buy stock in Oklo, consider this: The Motley Fool Stock Advisor analyst team just identified what they believe are the 10 best stocks for investors to buy now… and Oklo wasn’t one of them.

OKLO

Oklo and NuScale Power are two small modular reactor companies with differing prospects. Oklo has $2.5 billion in cash and no debt, positioning it as a cleaner investment despite not yet generating revenue. In contrast, NuScale, the only SMR company with design approval from the Nuclear Regulatory Commission, faces a class action lawsuit that has negatively impacted its stock.
