Oklo Inc. (OKLO.US), a U.S. nuclear energy startup, reported another quarterly loss in its latest earnings release after Tuesday's market close.

For Q3 2025, the company generated no revenue. Operating losses widened to $36.309 million, up from $12.282 million year-over-year. Net losses reached $29.722 million, compared to $9.96 million in the prior-year period. Per-share losses stood at $0.20, exceeding both the year-ago $0.08 loss and analysts' average estimate of a $0.13 loss. Shares fell nearly 2% in after-hours trading.

Oklo is developing "small modular reactor" (SMR) technology. Backed by OpenAI CEO Sam Altman, the startup aims to deploy its first commercial SMR within years. While no SMRs are currently operational globally, multiple firms are advancing the technology, which promises on-site power generation with significantly reduced approval, construction, and operational costs compared to traditional large-scale nuclear plants.

Despite recent declines—shares have dropped over 20% in November and nearly 46% since hitting an all-time high of $193.84 on October 15—Oklo’s stock remains up roughly 391% year-to-date, buoyed by strong market bets on AI data centers' energy demands.

**White House Reaffirms Nuclear Support** On Monday, U.S. Energy Secretary Chris Wright announced federal funding for next-gen nuclear plants, with $300–$400 million from the DOE Loan Programs Office earmarked for early-stage projects.

William Blair analyst Jed Dorsheimer noted Oklo’s alignment with the initiative, calling it a "household name in nuclear for the White House." The company’s Aurora reactor project and high-profile government ties—including CEO Jacob DeWitte’s Oval Office presence during an executive order signing—position it favorably. Oklo is also participating in three DOE reactor pilot programs.
