Amazon's Kuiper unit filed with the FCC to deploy up to 5,105 low-Earth-orbit satellites for 'Amazon Leo' direct-to-device service — voice, messaging and broadband to unmodified phones over Globalstar spectrum (Amazon is acquiring Globalstar for ~$11.6B). Deployment targets 2028, opening a third major D2D front.
AWS (Project Rainier) / Anthropic — AWS activated Project Rainier — nearly 500,000 of its own Trainium2 chips across multiple US data centers, one of the world's largest AI compute clusters and the biggest built on custom silicon rather than Nvidia GPUs. Anthropic trains and serves Claude on it (>5x its previous training compute), scaling toward 1M+ Trainium2 chips — a proof point that frontier-scale compute can run on a hyperscaler's in-house accelerators.
