SpaceXAI Targets 1 Million GPUs at Colossus as Aggressive Timetable Remains Unverified

SpaceXAI's Colossus buildout has become a focal point in the AI infrastructure race, with the company publicly targeting 1 million GPUs for its Memphis supercomputer facility by 2026 while a more aggressive capacity schedule remains unverified. Public company pages and filings confirm the broad 1 million-GPU roadmap, a roughly 1.0-gigawatt Colossus footprint, and GB200 and GB300 expansion phases, but they do not independently verify a one-million-GPU crossover during the week of September 28, 2026, or a 1.44 million-GPU year-end timetable.
