Tesla to End Model S and Model X Production, Repurpose Fremont Plant for Optimus Robot Manufacturing
Tesla CEO Elon Musk said during the Q4 2025 earnings call that production of the Model S and Model X will cease by Q2 2026, and Fremont will be repurposed to begin mass production of Optimus humanoid robots.
- Production end: Model S and Model X production will wind down next quarter and stop completely by the end of Q2 2026 — see Fox Business and Electrek.
- Factory pivot: Fremont S/X space will be retooled for large-scale Optimus humanoid robot production — reported by Fox Business and Electrek.
- Financials: Q4 2025 revenue slipped to $24.9 billion and full-year 2025 revenue was $94.8 billion, each down 3% year-over-year (Fox Business).
The end of an era
History: The Model S (launched 2012) and Model X (launched 2015) served as Tesla’s premium flagships and helped make the company a household name in electric vehicles.
Sales decline: Over recent years Tesla shifted emphasis to the lower-cost Model 3 and Model Y, and industry reports show the S and X accounted for less than 3% of Tesla’s 1.64 million deliveries in 2025 — see reporting from Fox Business and Edmunds.
Musk’s framing: On the Jan. 28 earnings call Musk called the move an “honorable discharge” and urged prospective buyers to order now, indicating no planned replacement for the models — reported by Fox Business and Electrek.
Financial picture and sales trends
Quarterly snapshot: Tesla reported Q4 2025 revenue of $24.9 billion (down 3% year-over-year) and full-year revenue of $94.8 billion (also down 3%).
Deliveries: EV sales dropped 16% quarter-over-quarter. Deliveries of “Other Models” (S/X, Cybertruck, Semi) fell to 11,642 in Q4 2025 from 23,640 in Q4 2024, per Electrek.
Pricing and demand: Tesla adjusted S and X pricing in 2025 — including a modest June refresh and fluctuating price moves — but demand lagged behind the mass-market Models 3 and Y (Edmunds).
Pivot to autonomy and robotics
Tesla framed the S/X phase-out as a strategic reallocation toward autonomy and robotics. Musk highlighted Optimus as a major growth focus, with plans to deploy a third-generation robot design and a new supply chain.
Reports indicate the Fremont S/X line — built with roughly a 100,000-unit annual capacity but underused — will be retooled to support robot production. Some outlets cite an ambitious potential target of up to 1 million Optimus units annually once scaled (Fox Business; Electrek).
Industry context: Retooling auto assembly for humanoid robots is technically complex — requiring new tooling, supply chains, and worker training. Critics point to high costs and execution risk; proponents say the upside is significant if Optimus achieves reliable revenue.
Fremont factory repurpose and capacity
Tesla plans investments across six new production lines in 2026 covering vehicles, robots, energy storage, and battery systems. The Fremont plant — central to the S/X programs — will be repurposed for Optimus and related initiatives (Fox Business).
Industry observers note the transition will affect tooling, supplier relationships, and workforce skills; Tesla’s track record of rapid pivots does not eliminate operational risk (Autoblog).
Impact on workers and suppliers
Workforce: Tesla has not announced immediate large-scale layoffs tied to the S/X phase-out. Possible outcomes include retraining for robotics assembly, reassignments, or role changes. Local labor needs will likely shift toward automation and software skills (Electrek).
Suppliers: Vendors that supplied S/X parts may lose business unless they secure contracts for robot components or other Tesla products. Local and regional suppliers should evaluate diversification and pursue new contract opportunities.
Market reaction and investor notes
Tesla’s stock closed at $430.46 on the announcement day, a slight decline of 0.10% as investors digested the strategic pivot. Near-term metrics to watch include vehicle margins and retooling costs; the long-term thesis depends on whether Optimus can translate into sustainable revenue.
Implications for Paso Robles, California
Economic ripple effects: Paso Robles hosts small manufacturers and suppliers that may indirectly serve Bay Area auto supply chains. A reduction in S/X demand could shrink opportunities for niche vendors, but Optimus contracts could open new markets for local firms (Fox Business; Electrek).
Workforce and training: Commuters and supplier employees could face transitions. Local community colleges and trade programs may see demand for retraining in robotics assembly, automation maintenance, and software testing.
Policy considerations: Local leaders should weigh incentives for high-tech manufacturing against preserving Paso Robles’ agricultural and cultural character. Workforce partnerships could ease transitions without heavy long-term subsidies.
On-the-ground concerns and practical advice
Dealerships and independent shops specializing in S and X service may see gradual demand shifts. Owners who want factory-new S/X vehicles have been urged to order now; used inventory may expand after production ends (Edmunds; CarBuzz).
For residents: Assess transferrable skills and training options now. Consider exploring local community college programs and workforce centers focused on automation, robotics maintenance, and logistics.
