Google’s $4.3 Billion Bet on Nuclear Comes Just Days After Amazon’s
Constellation Energy (CEG) shares rose 13% after Google agreed to a $4.3 billion power purchase deal, including 890 MW of new nuclear capacity. This follows a similar 20-year deal with Amazon (AMZN). The contracts total 3.6 GW, with Google's deal spanning 15-20 years. Constellation's valuation is below its 3-year average, at 21.6x forward earnings. Google (GOOG) aims to secure reliable power for its data centers, addressing grid constraints.

likely flat to slight downside as investors weigh higher power procurement costs against strategic stability.
The agreement is a strategic procurement, not a earnings driver, and the market has already priced most of the news.
Market effects
Boosts outlook for nuclear and utility stocks; underscores growing power demand from AI‑heavy tech firms.
Positive for U.S. power generation markets, especially in Illinois, Pennsylvania, and New Jersey where the reactors are located.
Highlights the intersection of AI data‑center growth and clean‑energy procurement, relevant to global investors tracking energy transition.
Counterpoint
The long‑term price lock could backfire if power prices rise sharply, pressuring Constellation's margins.
