This Week at Mach33

SpaceX partnered with Nvidia on the Starmind AI1 compute payload, the orbit-optimized Vera Rubin NVL72 design Musk expects to start flying next year; the company told investors this week it will build its compute exclusively on Nvidia hardware from here. Reports suggest SpaceX is in talks for roughly 130,000 acres of Louisiana marshland to expand Starship production and launch. Musk confirmed a hiring push for SpaceX's on- and off-Earth AI supercomputer clusters, the staffing behind 1.4 GW of nameplate compute today and more than 2 GW guided by year-end.

This week's analysis, "SpaceX's First Public Quarter: AI Segment EBITDA Turns Positive Two Years Ahead of Our Model," reads the August 4 print against the Mach33 SpaceX Gigamodel: the AI segment turned adjusted EBITDA positive at $1.15 billion, a swing from negative $609 million in Q1, where our model carried it negative through 2028. Contract signings got it there, $14.1 billion of Cloud Services Agreements with Google and Anthropic named and $6.7 billion more signed in the first weeks of Q3. First-half AI revenue of $3.4 billion has already run 1.9x our full-year figure, and first-half AI capex of $23.6 billion has passed our full-year number by a third. The segment still loses money from operations, and one quarter of ramp economics on capacity built earlier is not steady state.

SpaceX's First Public Quarter: AI Segment EBITDA Turns Positive Two Years Ahead of Our Model
Aug 5, 2026 SpaceXxAIEarnings

SpaceX's first quarter as a public company beat consensus revenue by 13.6%, and its AI segment turned EBITDA positive on $14.1 billion of contracted Cloud Services Agreements, two years earlier than our model assumed. We read the quarter against the Mach33 SpaceX Gigamodel, segment by segment, and record what we are revising.

Brief: The Radiation Tax
Aug 4, 2026 Orbital Data CentersRadiationSatellite

An interactive research brief on how radiation affects AI compute in low Earth orbit. At 550 km, a modeled 1,000-satellite fleet sees tens of thousands of daily glitches, but error correction and recovery software keep downtime to about 8 minutes a year — while shielding mass drives nearly all of the modeled ~$82k annual radiation cost per satellite.

SpaceX Nears 130,000-Acre Louisiana Marshland Deal for Starship Expansion
SpaceXStarship

SpaceX and the state of Louisiana are close to finalizing an agreement for roughly 130,000 acres of Vermilion Parish marshland at Pecan Island, with Gov. Jeff Landry expected to announce the deal later this month. This remains a pending deal and may not close, but if completed, the acreage is large enough to materially support the Starship buildout.
