SpaceX Seeks Starbase Tax Break for $24 Billion Gas Plant and Supercomputer

SpaceX has asked the city of Starbase, Texas, for a property tax break on a gas-fired power plant and a "super-compute facility" with an estimated capital investment of $24 billion, according to a one-page city notice dated November 6, 2026.

The notice lists SpaceX (NASDAQ: SPCX) as both applicant and property owner. The Starbase City Commission will consider a tax exemption agreement under Chapter 312 of the Texas Tax Code, plus a related economic development agreement, at its meeting on December 9, 2026, at 7:00 p.m. Nothing has been approved yet.

The stakes are considerable. SpaceX plans to build, own, and operate the plant and the computing facility on a 444-acre tract between Boca Chica Blvd and the Port of Brownsville, inside the Cameron County Enterprise Zone. The filing arrives as the company's AI compute-leasing business is already generating more revenue than Starlink, and as its own filings list access to sufficient power as a risk.

What does the notice commit SpaceX to?

Notably little in the way of detail. The one-page document omits the size and length of the requested exemption, the plant's generating capacity, the scale of the computing operation, and who will use that computing power. SpaceX made no comment on the plan.

Texas law provides some pressure toward disclosure. Any final agreement must list the kind, number, and location of improvements, and must recapture lost tax revenue if the owner does not build them. The December agreement, in other words, should show more than the notice did.

The scale of the ask is large by any measure. The project's estimated cost of $24 billion runs about 17 times the value of SpaceX's 18,712 Bitcoin (CRYPTO: BTC) holdings, worth $1.39 billion. The company reported $93.52 billion in cash in the second quarter, which places the capital program well within its financial capacity.

The tax break itself, whose size has not been disclosed, would go to a company with a market value of $1,872,482,600,000.

Why does SpaceX want its own power?

Building a dedicated plant could let SpaceX avoid waiting for a connection to the main Texas grid. Separately, a pending state air filing for a SpaceX "Boca Chica Facility," reported by The 956 Report, covers 35 temporary gas turbines totaling about 748 megawatts. The 956 Report said those units would later be replaced by eight permanent turbines totaling about 708 megawatts.

A SpaceX affiliate has also filed plans for an 8-mile gas pipeline called Starpipe, scheduled to enter service by January 2027, to supply Starship fuel production. The city notice does not tie the power plant to that pipeline. The two projects could, however, share the same gas supply.

The timing matters beyond Boca Chica. SpaceX's own filings list obtaining enough power as a risk, and the company is aiming to secure its own supply at the same moment.

How big is the computing business behind the plan?

Revenue figures from the third quarter show why the supercomputer portion of the project carries commercial weight. Total revenue rose 161%. AI revenue grew ninefold, reaching $7.6 billion — more than the Starlink internet business, which brought in $5.2 billion.

SpaceX leases compute capacity to outside developers, including Anthropic. Each new site therefore supports a business line that is already generating substantial income rather than a speculative one. The Starbase filing gives that business a potential physical anchor: a dedicated power source paired with on-site computing infrastructure.

Where does the political risk sit?

The nearest risk is not in Starbase but in Austin. Voters rejected data centers in 40 of 41 local ballot measures nationwide. In the November 3 midterms, Democrats won the Texas governor's office, and Governor-elect Gina Hinojosa has said she would ban new data center projects until lawmakers pass rules.

A city built around SpaceX will probably approve the exemption. A city vote, however, cannot protect the project from two things: a state ban, and the state air permit. Either one could delay the timeline even if the tax break is in place.

What is the market reading?

The market context is mixed. SpaceX closed November 9 at $142.07, up $7.80, or 5.81%. No source links that gain to the Starbase plan, and shares remain well below the post-IPO high of $225.64. Over the past month, the stock is down 12.61%.

The equity picture frames the December decision. A ban that covers private power plants would undercut the project's premise. So would a close below the post-IPO low of $104.83, which would signal deeper investor concern independent of Starbase.

What comes next?

Two tests will decide whether the plan moves forward. The first is the December 9 vote and the terms of the final agreement, which Texas law requires to specify the improvements and recapture provisions. The second is any state action on data centers after Governor-elect Hinojosa takes office.

Between them sits a $24 billion capital commitment, a growing AI revenue stream, and a company that has decided generating its own power is faster than waiting for the grid. The Starbase commission's vote on December 9 will show whether the city agrees to help pay for it.
