How this was made
The 30-second read
Why it matters

What to watch
Year‑to‑date 15% decline in Constellation and execution risk on uprates may temper the rally.
Background
A hyperscaler (Google) has entered a 20‑year power purchase agreement with Constellation Energy, funding upgrades at existing nuclear reactors and prompting a rally in peer nuclear generators.
Ticker impact
Constellation Energy signed a 20‑year $890 MW power purchase agreement with Google, driving a 12% pre‑market jump.
