TSMC to Produce Chips for $25B Tesla-SpaceX Terafab and $15B Arm AGI CPU
Tesla and SpaceX's Terafab project could tie up to 1 million wafer starts per month—around 70% of TSMC's capacity—to produce 100–200 billion custom chips annually. Arm's entry into chip sales with a $15 billion AGI CPU business, anchored by Meta, will use TSMC for production and add high-margin fabrication orders.
1. Terafab Capacity Demand
The Terafab initiative, a joint $25 billion effort by Tesla and SpaceX in Austin, is projected to ramp to approximately 1 million wafer starts per month—representing nearly 70% of TSMC’s current global foundry capacity. This scale underscores the automaker and aerospace firm's strategy to secure long-term chip supply for FSD, Cybercab and robot applications.
2. Arm's AGI CPU Manufacture
Arm’s debut chip sales revolve around its new AGI CPU, a 136-core, 300-watt data-center processor with Meta as initial customer. By shifting from licensing to fabrication, Arm targets $15 billion in annual chip sales within five years, with TSMC handling full production and adding high-margin orders to its backlog.
3. Implications for TSMC
Combined demand from Terafab and Arm orders could strain TSMC’s capacity and justify further capacity expansion or premium pricing. The projects also diversify TSMC’s revenue streams and could accelerate capital expenditure plans to accommodate growing foundry demand.
