US Stocks Open Higher as Nasdaq Gains 0.6%, Constellation Energy Jumps 12%

The Constellation move is the tell: a single corporate power purchase agreement is now enough to reprice a utility-scale generator, which says the market is treating firm, dispatchable capacity as the scarce input for AI buildout rather than as a commodity. That reframes nuclear operators as counterparties to hyperscalers, not just merchant generators, and puts every operator with uncommitted baseload in a different negotiating position. The open question is whether this becomes a template — whether other large-load buyers follow with their own long-dated contracts — or remains a one-off tied to a single buyer's needs.
