Today's Threads3 threads
①
Power infrastructure is now the binding constraint
SpaceX committed 10GW by 2027 (Microsoft offtaker), PPL projects 32GW with Blackstone's $15B financing, and Constellation won 920MW—but Texas Governor Abbott's data center pause threatens 20% of US pipeline.
②
Inference silicon competition is concurrently fracturing into custom architectures
Nvidia's Vera Rubin exclusive (SpaceX/Stargate) validates next-gen demand, while AMD's Taalas acquisition—embedding AI weights directly in silicon—reflects industry consensus that inference requires model-specific chips, not generic GPUs.
③
The dynamic exposes geopolitical divergence
China's million-GPU campus expands unfettered, while US infrastructure faces regulatory headwinds and supply tightness (SK Hynix $38B new fabs, RAM pricing reverted to 2007 levels). NScale's $25B IPO and CleanSpark's $6.6B lease underscore America's dependence on capital markets for competitive parity.
