SpaceX committed over $2.8B to gas turbine purchases in recent months to power xAI's data centers, the company disclosed in its IPO filing on Wednesday. The investment includes a $805M deal signed in March 2026 and a pending $2B mobile turbine agreement from late April, both covering equipment through 2029. The spending doubles down on portable generators even as xAI faces a lawsuit from the NAACP alleging 27 turbines at Colossus 2 operate without appropriate permits.
SpaceX operates two data centers for xAI — Colossus 1 in Memphis, Tennessee and Colossus 2 in Southaven, Mississippi — with enough servers to consume approximately 1 gigawatt of power as of March 2026. The company added 19 portable turbines to Colossus 2 over the past two months, bringing the site's total to 46 units. SpaceX is leasing access to some Colossus servers to Anthropic for $15B annually, a deal we covered last week, and Musk said on Wednesday the company plans to sign additional leasing agreements.

The turbine strategy solves a near-term constraint — grid power shortages are bottlenecking the US data center boom — but introduces regulatory and public-relations friction. Portable turbines can operate without a clean air permit for one year under existing rules, a window SpaceX has used to accelerate deployment. The NAACP lawsuit alleges the unpermitted generators pose risks to public health and local air quality.
Key facts
- 01SpaceX committed $2.8B to gas turbine purchases in recent months to power xAI data centers.
- 02The company signed a $805M turbine deal in March 2026 and a $2B mobile turbine agreement in late April.
- 03Colossus 2 now operates 46 portable turbines, 27 of which allegedly lack appropriate permits.
- 04SpaceX is leasing Colossus servers to Anthropic for $15B annually through 2029.
- 05The IPO filing shows $14B in data center construction in progress.
SpaceX's IPO prospectus reveals $14B in construction in progress, including data center equipment not yet operational. The filing positions the company as both a satellite internet operator and a cloud infrastructure player, with xAI's Grok chatbot and third-party leasing revenue as growth drivers. The company is targeting a Nasdaq debut in the coming weeks.
The March turbine agreement names no vendor; the late April $2B deal remains pending. Both contracts run through 2029, aligning with the Anthropic leasing term and suggesting SpaceX expects sustained compute demand even as grid upgrades lag behind.

The regulatory filing does not specify whether the turbines will replace older units or expand capacity beyond the current 1 gigawatt. The 27 allegedly unpermitted turbines represent a majority of Colossus 2's current generator count, making the lawsuit a material operating risk for the site.
Musk has framed xAI's infrastructure buildout as necessary to compete with OpenAI and Anthropic, both of which rely on third-party cloud providers for the majority of their compute. SpaceX's vertical integration — owning the data centers, the power generation, and the AI unit itself — is unusual among AI labs but consistent with Musk's operational playbook at Tesla and Starlink.
The turbine purchases sit inside a broader capital deployment story. SpaceX's IPO filing shows the company burning cash on rocket development, satellite manufacturing, and now AI infrastructure simultaneously. The $2.8B turbine commitment is roughly 20% of the $14B in construction in progress, a ratio that suggests power is consuming a meaningful share of the data center budget.
Grid constraints are not unique to xAI. Every major AI lab and cloud provider is scrambling for megawatts, but most are waiting for utility upgrades rather than deploying portable generators at scale. SpaceX's willingness to absorb the regulatory friction of unpermitted turbines reflects a bet that speed matters more than permitting clean-up costs. That calculus works if the Anthropic lease and future deals generate revenue faster than lawsuits and fines accumulate.
