Tesla announced a massive joint venture with SpaceX to build the 'Terafab,' aiming for domestic terawatt-scale AI chip production.
Terafab Chip Manufacturing Initiative
- Tesla and SpaceX are collaborating on the 'Terafab' project to produce a terawatt of AI compute chips domestically1
The facility will manufacture two chip types
Optimus and FSD Development Milestones
- The chips produced will power Optimus robots, which are projected to save Tesla up to $2 billion annually in internal labor costs if deployed7
- Tesla removed safety monitors in Austin, reporting zero major incidents over the last 100,000 miles, potentially paving the way for 'Unsupervised FSD' approval in California7
- The company's long-term success is tied to securing full autonomy approvals for FSD and meeting ambitious Optimus timelines5
Operational Risks and Margin Pressures
- A proposed 145% tariff on Chinese battery inputs, such as graphite, poses the number one threat, potentially adding $3,000 to $5,000 to the cost of each Model Y7
- Current financial health shows gross margin near 18.03% TTM, while FY2024 EPS fell significantly (52.85%) due to price cuts and product mix shifts6
- Margin pressure is also anticipated from the ramp-up phase of new factory operations6
