What's happening
Big Tech companies are making substantial financial commitments to nuclear power developers to meet surging electricity demands from AI data centers. Meta's January 9, 2026 agreements with four nuclear companies will deliver 6.6 GW of capacity by 2035, including a 1.2 GW nuclear campus in Pike County, Ohio with Oklo's Aurora Powerhouse reactors potentially online by 2030. The Meta-TerraPower deal funds two Natrium units providing 690 MW as early as 2032, with rights to expand to 2.8 GW baseload plus 1.2 GW storage capacity.
Amazon and Google have also entered the nuclear space, with Amazon partnering with X-energy for over 5 GW of small modular reactors by 2039 and Google signing with Kairos Power for deployment by 2030. These power purchase agreements provide the revenue certainty that developers need for project financing, as U.S. electricity use is projected to increase 1% in 2026 and 3% in 2027 driven by data center demand.
Why it matters for markets
The nuclear sector is experiencing a market revaluation as Big Tech's long-term power purchase agreements create revenue stability for previously speculative nuclear startups. Oklo's market capitalization reached $9 billion as of April 4, 2026, though shares remain down 71% from their 52-week high of $193.84. Constellation Energy, with an $103.80 billion market cap and stock price of $286.50, secured over 2.1 GW in capacity commitments from Meta through 20-year agreements covering its Perry, Davis-Besse, and Beaver Valley plants.
These corporate commitments address a critical financing gap in nuclear development, as senior analyst Shioly Dong noted that tech giants "create the revenue certainty that commercial banks will require for the construction debt." NuScale Power, with a $2.93 billion market cap, represents the broader small modular reactor sector benefiting from this trend. The financial backing enables nuclear developers to move beyond concept stage toward actual deployment, with first projects potentially online by 2030.
Sectors and assets to watch
Nuclear technology companies are the primary beneficiaries, with Oklo (OKLO) gaining 5.24% to $50.25 following its Meta partnership announcement. Constellation Energy (CEG) at $286.50 per share offers exposure to established nuclear operations with expansion potential, while NuScale Power (SMR) at $9.21 provides access to the small modular reactor market despite trading near 52-week lows.
Utility companies with nuclear assets or development capabilities are positioned to benefit from increased corporate demand for carbon-free baseload power. The sector's revenue model is shifting from speculative development to contracted cash flows, creating more predictable investment opportunities as AI-driven electricity demand accelerates.
What to watch next
Monitor additional Big Tech nuclear announcements as companies seek to secure long-term clean energy supplies for expanding AI operations. Key developments include construction timelines for Meta's Ohio nuclear campus, regulatory approvals for TerraPower's Natrium technology, and whether other technology companies follow with similar multi-gigawatt commitments that could further validate the nuclear investment thesis.
