Texas Anchors Musk’s $1 Trillion Chip Manufacturing Plan

By Priya Raman

Tesla and SpaceX are building Terafab, a Texas chip fabrication plant that Musk estimates could cost $1 trillion and target 1 million wafers a month. A wafer is a thin silicon disc used to manufacture semiconductors.

The source presents the cost as an estimate rather than a disclosed funded budget. It provides no construction schedule, financing mix, customer commitments or evidence that the output target will be sold.

What does the Texas strategy require?

Musk stated on Nov. 7 on X: “SpaceX and Tesla have prospered in Texas, because we were not constantly operating under an oppressive and extractive state government.” The statement provides no supporting operating or tax data.

Dan Ives, a technology analyst and one of Wall Street’s best-known Tesla bulls, said on The Pomp Podcast: “He can’t just pick up and go to Florida.”

He added that “SpaceX needs to build themselves into a hyperscaler and Texas is a key part of it,” and that Musk would need to “olive branch a bit” with incoming state leadership. A hyperscaler operates large-scale cloud-computing infrastructure. The argument rests on infrastructure location and political relations, not a lower personal tax rate.

What is pending at Starbase?

SpaceX also seeks a gas-fired power plant and supercomputer at Starbase, with a first phase estimated at $24 billion. A gas-fired plant generates electricity by burning natural gas. The report does not explain how much of the first phase covers each component.

The request still awaits a tax decision from Starbase’s city commission. The report does not state the proposed tax amount, incentive terms or decision schedule. It therefore describes an approval-dependent project rather than a committed operating expansion.

How have investors reacted?

SpaceX (NASDAQ:SPCX) shares fell 12% over the past month to about $143. Board member Donald Harrison resigned one day after the elections.

Tesla (NASDAQ:TSLA) slipped less than 1% over the same month but remained 16% lower for the year.

The report does not attribute the share declines or Harrison’s departure to any single cause, and it gives no public explanation for his resignation. The market movement does not prove that Texas policy caused either development.

Can moving to Florida reduce Musk’s taxes?

Texas voters approved Proposition 4 in 2019 with 77% support. Any future state income tax now requires a two-thirds majority in the legislature. Florida has no personal income tax, and neither does Texas.

Musk’s proposed Austin-to-Miami move therefore produces no state income-tax saving on his pay. That includes stock compensation linked to Tesla’s 2025 CEO Performance Award; a linked report put a $158 billion price tag on Musk’s pay for last year.

The arithmetic covers personal state income tax only; it does not assess federal, local or property-tax consequences. Texas also taxes business property in the local taxing unit where it has “taxable situs,” meaning the physical location subject to local property tax.

A fabrication plant and power plant remain in Texas regardless of where Musk resides. Leaving could also consume political goodwill, according to the source’s reasoning, without producing an income-tax saving.

How does the relocation arithmetic work?

A state can tax nonresident income connected to sources inside that state. California, for example, taxes residents on all income but nonresidents only on California-source income. That rule limits the benefit of relocation when work or equity remains tied to the former state.

• A remote worker earning $150,000 moves from a 5% flat-income-tax state to one with no income tax. Annual saving: $7,500.
• Selling a $400,000 home costs about 6%, or $24,000. Moving costs another $10,000.
• Total switching cost: $34,000. Break-even: about 4.5 years. Ten-year gain: $41,000.
• In the Texas-to-Florida version, the rate gap is 0%. Annual saving: $0. There is no break-even, and the $34,000 switching cost becomes a loss.
• If income remains linked to the old state, the saving shrinks toward $0.

What should a tax-driven mover verify?

1. Find the actual rate gap. Check both states’ current brackets through their revenue departments and apply them to actual taxable income. If both rates are zero, no income-tax saving exists to capture.
2. Separate portable income from fixed income. Remote salary moves with the worker. On-site work, a local business, rental property and unvested stock earned in the former state may remain taxable there.
3. Ask payroll how equity will be allocated. Stock vesting after a move is often split between states according to days worked in each. Obtain the allocation in writing before setting a moving date.
4. Count all switching costs. Include home-sale fees, moving expenses, higher insurance and property taxes. Divide the total by annual savings to calculate the break-even period.

The next observable signal is the Starbase city commission’s ruling on the power-plant tax decision under Texas’s incoming leadership. Until then, the $24 billion first phase remains a proposal awaiting that decision.

What other material accompanied the report?

The package also promoted a free report on seven suppliers tied to the same AI-infrastructure wave. A sponsored Fisher Investments guide, offered free, covers retirement costs, cash-flow sources and safe annual withdrawals. Its promotional copy describes the shift from saving to drawing income as consequential and says many investors lack a plan. It provides no figures or projections.
