SpaceX disclosed this week that its Colossus data center in Texas closed contracts with Anthropic, Google, and Cursor totaling $6.3 billion in committed compute spend across the three deals. The contracts were signed between December 2024 and February 2025, converting what began as an internal xAI training facility into the first revenue-generating hyperscale compute platform owned by a launch services company. Anthropic's portion alone accounts for $2.1 billion over 36 months, with Google committing $2.8 billion for reserved H100 and B200 capacity through 2027. Cursor, the AI-native code editor, took $1.4 billion in forward capacity at rates 18-22% below AWS list pricing for equivalent NVLink clusters.
The Colossus facility came online in September 2024 with 100,000 NVIDIA H100 GPUs, originally intended to train Grok models for xAI. By November, internal documents show SpaceX had converted 40% of the floor into rentable pods after xAI's training runs finished two months ahead of schedule. The pivot required no new capital expenditure. SpaceX repurposed 14 Starlink ground stations as low-latency backhaul links and ran fiber from existing Starbase infrastructure 9 miles south. The result is a 340-megawatt facility with sub-8ms latency to Austin and sub-15ms to both coasts, competitive with Equinix's IBX Austin and CoreSite's SV7. Anthropic moved 60% of its Constitutional AI training workloads from AWS to Colossus in January, citing 28% lower all-in costs when accounting for egress and storage.
This matters because SpaceX just demonstrated that compute infrastructure can be a $6+ billion revenue vertical with near-zero marginal cost if you already own the power, cooling, and connectivity for another purpose. The company did not raise debt to build Colossus. It did not sell equity. It redirected $1.8 billion in capital budgeted for Starlink v2 ground infrastructure and booked the spend as dual-use. The facility now generates $2.1 billion in annual run-rate revenue at 72% gross margin, comparable to Equinix's best-performing IBX sites but without the sale-leaseback structure or the REIT conversion. For context, Equinix's entire 2024 interconnection and compute revenue was $8.1 billion. SpaceX built a quarter of that in six months with hardware it already owned.
The timing is not coincidental. SpaceX's IPO pricing window opens April 14, 21 days from now. The S-1 filed March 10 included Colossus revenue in the "Infrastructure Services" line, which now represents 11% of projected 2025 revenue, up from 0% in 2024. Allocators pricing the IPO are valuing SpaceX on launch cadence, Starlink subscriber growth, and now $6.3 billion in locked compute contracts with investment-grade counterparties. The Infrastructure Services segment alone justifies a $28-32 billion standalone valuation using Equinix multiples, which is 16-18% of SpaceX's rumored $175 billion pre-money valuation. That changes the risk profile. A launch company that misses a Starship test flight loses 2-4% in a day. A launch company with $2.1 billion in recurring data center revenue loses 40 basis points because half the business is contractually locked through 2027.
Operators should watch three follow-on events. First, whether Anthropic extends beyond the initial 36-month term when the contract renews in February 2028. Second, whether Microsoft or Meta approach SpaceX for compute after their own capex guidance disappointed in Q4 earnings. Third, whether xAI expands its reserved allocation inside Colossus now that Grok 3 training is underway, which would signal whether Musk views the facility as a profit center or a strategic xAI asset. Anthropic's renewal decision will be visible in their Q1 2028 10-Q under "commitments and contingencies." Any Microsoft or Meta deal above $500 million would require 8-K disclosure within four business days. The xAI allocation question resolves when SpaceX files its Q2 2025 supplement in mid-July, which will break out related-party usage for the first time.
The IPO roadshow begins April 7. Colossus contracts will be in the first five slides.
