Constellation Energy Corporation (CEG) shares dropped Wednesday alongside other nuclear energy stocks, as a planned mega data center deal hit a major roadblock.

What Happened: According to a Financial Times report, Blue Owl Capital has decided not to move forward with financing a $10 billion data center project after negotiations with Oracle and lenders stalled. The Michigan facility was supposed to be a massive 1-gigawatt site built specifically to handle artificial intelligence workloads.

The collapse of funding talks leaves the project's future uncertain, with no replacement financial backer currently lined up. Sources pointed to concerns about rising debt levels and the enormous scale of spending required for AI infrastructure.

Why It Matters: Here's the thing about nuclear stocks lately—they've been riding high on the narrative that massive AI data centers will need serious baseload power, and nuclear fits that bill perfectly. When a high-profile project like this hits financing trouble, it raises questions about whether the AI-driven electricity demand boom is as certain as investors have been betting.

Nuclear operators have essentially positioned themselves as picks-and-shovels plays on the AI infrastructure buildout, which makes the sector particularly sensitive to any signs of project delays or funding uncertainty.

Price Action: At the time of writing, Constellation shares were trading 8.14% lower at $335.84.
