Nvidia, OpenAI and SB Energy confirm the PORTS-Pike campus in Pike County, Ohio — but the SEC-filed guarantee behind it has shrunk from a discussed $250 billion to $105 billion in a week, reviving circular-financing questions Jensen Huang tried to shut down on X. Plus: New South Wales mandates wind power for new data centers, a Texas gas-plus-nuclear plant advances toward powering a Crusoe campus, Kentucky taxpayers question fifty-year tax breaks, an X thread argues grid infrastructure is the real AI bottleneck, and Sunrun brings home batteries into the hyperscaler capacity push.

Nvidia's financing guarantee for OpenAI's ten-gigawatt Ohio campus reportedly shrank from $250 billion to under $120 billion this week, even as Nvidia weighs a separate stake in SB Energy — while Chicago moves toward a data center moratorium, a Missouri landowner defies the national pushback, and the industry debates whether power or demand is the real bottleneck.
