Nuclear Stocks Oklo, NuScale Power, and X
Shares of Oklo (OKLO), NuScale Power (SMR), and X-Energy (XE) surged after the U.S. House passed the Ratepayer Protection Act, which may boost demand for their small modular reactors as data center power sources. XE stock rose 12.08% to $16.33. Analysts see 106% upside for XE, with a $33.71 average price target.
How this was made

The 30-second read
Why it matters
The legislation directly benefits small modular reactor producers by creating a new customer base, prompting immediate price spikes in their stocks.
Market read
The bill introduces a novel demand driver for nuclear SMR companies, making the news highly relevant for traders in this niche sector.
What to watch
Regulatory approvals for SMR deployment and financing challenges could delay commercial rollout.
Background
The Ratepayer Protection Act was passed by a 417‑3 vote, mandating large data centers to cover extra grid costs, creating a potential market for behind‑the‑meter power solutions.
Ticker impact
Oklo shares rose sharply after the U.S. House passed the Ratepayer Protection Act, which could boost demand for its small modular reactors.
upward pressure in the near term
Legislation directly creates a market for behind‑the‑meter nuclear power for data centers.
NuScale Power stock jumped on the same legislation, as the Act may drive data‑center operators toward its light‑water SMR modules.
moderate upside
Regulatory demand shift favors NuScale's technology.
X‑Energy led the rally with a 12% gain after the Act’s passage, reflecting investor optimism about its SMR offerings for data centers.
strong short‑term upside
The new law creates a clear use case for X‑Energy's reactors.
Market effects
Boosts the nuclear SMR sector and related clean‑energy infrastructure stocks.
U.S. data‑center market may shift toward on‑site nuclear power.
Sets a precedent for other countries considering similar data‑center energy policies.
Counterpoint
If data‑center operators face higher capital costs, they may still prefer grid power, limiting SMR uptake.
