Spacex Poised for $500B Revenue With 10GW Compute by 2027

WHO:

SemiAnalysis - Elon Musk announced SpaceX's ambitions for compute capacity.

SemiAnalysis - Microsoft is identified as a major offtaker for SpaceX's compute capacity.

WHAT:

SemiAnalysis - SpaceX is on track to build approximately 10 GW of compute capacity by the end of 2027.

SemiAnalysis - SpaceX aims to deliver an incremental 6-8 GW in 2027 alone.

SemiAnalysis - The projected annual revenue run-rate for SpaceX could reach $300B by 2027.

SemiAnalysis - Microsoft has signed contracts for 10 GW of datacenter capacity year-to-date, valued at over $300B.

WHERE:

SemiAnalysis - The Southaven Power Plant has expanded from 27 turbines (~495 MW) to 69 turbines (>1.2 GW) between February 2026 and July 2026.

SemiAnalysis - The construction of "MiniHard" is expected to reach 450-500 MW in approximately five months.

WHEN:

SemiAnalysis - SpaceX's compute capacity is projected to be built by the end of 2027.

SemiAnalysis - Microsoft signed a $250B agreement with OpenAI in October 2025.

SemiAnalysis - The construction of "MiniHard" began in March 2026.

WHY:

SemiAnalysis - SpaceX's rapid build pace is driven by the high demand for large-scale compute and the profitability of serving AI inference tokens.

SemiAnalysis - Microsoft aims to capture a $100M/MW/year revenue opportunity by increasing its datacenter capacity.

HOW:

SemiAnalysis - SpaceX plans to utilize onsite gas generation to support its compute capacity ramp-up.

SemiAnalysis - SpaceX is expected to finance its capital expenditures through vendor financing from Nvidia and high pricing strategies for its compute offerings.

Elon Musk has announced that SpaceX is on track to build approximately 10 gigawatts of compute capacity by the end of 2027, with Microsoft identified as a major offtaker for this ambitious project. The company aims to deliver an incremental six to eight gigawatts in 2027 alone, potentially generating an annual revenue run-rate of $300 billion by that time. Additionally, the Southaven Power Plant has expanded significantly, increasing its turbine count and capacity, while the construction of a new facility called "MiniHard" is expected to reach 450 to 500 megawatts in about five months.
