Musk to Build World's Largest Chip Factory! TeraFab Targets Annual Production of 200 Billion Chips, Surpassing TSMC

Elon Musk announced on X platform that the TeraFab project will officially launch within a week, aiming to build the world’s largest semiconductor manufacturing facility with an annual output of 100 to 200 billion chips.

In a 7-day countdown, Musk announced on X last night (14th) with the phrase “Terafab Project launches in 7 days” that his latest semiconductor ambitions are about to begin.

It is understood that the core goal of TeraFab is to build a massive manufacturing plant in the U.S. with an annual capacity of 100 to 200 billion chips, claiming that its scale will surpass the total of TSMC’s entire Taiwan operations.

Breaking supply chain bottlenecks: Tesla’s chip anxiety

The direct motivation behind TeraFab is Tesla’s long-standing pressure from chip supply issues. From the Model 3 production hell, expanding the Dojo supercomputer, to mass production of Optimus robots, Tesla’s demand for advanced chips has exceeded what the current supply chain can handle.

Major foundries like TSMC and Samsung are under tight schedules, with NVIDIA and AMD also vying for capacity. Almost every core business line of Tesla is constrained.

If TeraFab becomes a reality, it would mean Musk is trying to take control of the critical chip manufacturing card, just as he used SpaceX’s self-made rocket engines to break the traditional aerospace supply chain logic.

Smoking cigars inside a wafer fab?

However, TeraFab has been controversial from the start. Musk publicly suggested building a 2nm wafer fab that doesn’t require traditional cleanroom facilities, even claiming he could “smoke cigars inside the wafer fab,” which sparked strong backlash in the semiconductor industry.

It’s important to note that 2nm process nodes have extremely low tolerance for particle contamination; any dust, skin flakes, or ash could cause large-scale wafer scrap. The existence of cleanrooms is not mere conservatism but a necessary engineering reality.

Industry insiders generally believe Musk’s comments reveal a lack of basic understanding of the physical limitations of chip manufacturing, or are simply a rhetorical tactic: first throwing out extreme statements to generate buzz, then following up with a “pragmatic version.”

Additionally, the target of producing 100 to 200 billion chips annually is also questionable. TSMC’s total shipments in 2024 are estimated to be around 30 to 40 billion chips. If TeraFab claims to surpass this with a brand-new plant, such capacity planning would require disruptive process innovations, enormous capital investment, and several years of construction.

Possible paths: licensing, partnerships, and capital injection

From a practical perspective, analysts suggest TeraFab’s approach might include three strategies:

First, signing technology licensing agreements with existing chipmakers like Intel or TSMC to acquire process knowledge rather than developing from scratch.

Second, deepening cooperation with Intel Foundry Services (IFS) to leverage existing facilities and process capabilities for rapid capacity expansion.

Third, injecting capital into existing production lines to gain priority in capacity through financial investment.

All three routes avoid “breaking cleanroom standards,” instead aligning with Musk’s usual strategy of “integrating existing resources and accelerating scale” in other fields.

CHIPS Act tailwinds and geopolitical background

TeraFab’s emergence coincides with the momentum of U.S. semiconductor localization policies. If Musk can frame TeraFab as a “national security solution to reduce dependence on Taiwan,” it could enjoy significant policy support.

The explosive growth in AI-driven computing demands also provides legitimacy: the global chip shortage is no longer just a supply chain issue but a core national competitiveness concern.

Tesla, NVIDIA, AMD are all queued at the same bottleneck. If TeraFab can provide even part of the alternative capacity, market potential exists. The question remains: what will Musk reveal in 7 days? A detailed engineering roadmap or just another concept that stirs public opinion? That’s what the semiconductor industry is eagerly awaiting.
