Oklo Inc. (OKLO) saw its stock price plummet 5.06% during intraday trading on Monday, reflecting significant selling pressure.

The decline follows news that Oklo is expanding its strategic partnership with Sweden's Blykalla to accelerate fast-reactor commercialization. The collaboration involves Blykalla planning to deploy $100 million to $200 million of investment in U.S. workstreams, subject to approvals, and includes technical support for Oklo's reactor pilot project. However, investors may be reacting to concerns about execution risks, potential dilution, or the costs associated with the partnership.

Additionally, the stock has been underperforming broadly, with shares down approximately 55% over the past six months due to ongoing worries about valuation and execution challenges, which likely contributed to the negative sentiment during the session.
