Report: Samsung's Taylor plant in the US delays mass production until 2027, potentially affecting Tesla's AI chip supply

Samsung Electronics faces uncertainty in the mass production schedule at its Taylor wafer fab in Texas. According to South Korea’s JoongAng Daily, the full-scale production at this plant may be delayed until early 2027, which could impact supply of advanced process chips to major clients like Tesla.

JoongAng Daily reports that the Taylor plant is planned to produce Tesla’s AI5 and AI6 chips, with Samsung having multi-billion dollar contracts with Tesla. Citing sources, the report states that the factory has begun trial runs, but full-scale production has experienced significant delays and some issues affecting capacity ramp-up.

Samsung responded in the report, saying that “start of production” should be understood as completing production readiness by the end of 2026, and a company spokesperson stated that the factory is expected to be fully operational by then. The report also mentions that Samsung expects to provide a clearer production roadmap by June.

For investors, the schedule fluctuations at Taylor not only relate to specific customer order deliveries but also influence Samsung’s 2nm process development and whether its foundry business can turn profitable by 2026. Execution progress is a key variable.

Discrepancies in mass production timeline: pointing to early 2027, Samsung says ready by late 2026

JoongAng Daily reports that the “full-scale production” at Taylor has been pushed back to early 2027, and notes that no specific start date has been set yet. Sources say the factory has begun trial runs, but several issues are delaying the full ramp-up.

Samsung clarified in the report that “start of production” should be understood as completing production readiness by the end of 2026, with full operation expected then. The company also plans to provide a clearer roadmap in June.

Tesla AI5 and AI6 chips face uncertainty: major client delivery schedules may be disrupted

JoongAng Daily points out that if the delay at Taylor is confirmed, it could affect key tech clients including Tesla. The report emphasizes that the plant is planned to produce Tesla’s AI5 and AI6 chips, with Samsung holding multi-billion dollar contracts with Tesla.

Given that advanced process lines require trial runs, capacity ramp-up, and yield improvements, delays or ambiguity in the production schedule could directly increase supply visibility risks for clients and impact market expectations for order fulfillment.

2nm progress under scrutiny: Taylor and Pyeongtaek developed in parallel, resource allocation adjusted

As attention turns to the Taylor plant’s ramp-up, Samsung’s 2nm plans are also being reassessed. JoongAng Daily states that during Samsung’s January earnings call, the company announced that its second-generation 2nm process (SF2P) will enter production this year.

The report also notes that 2nm process development is planned to proceed in parallel at the US Taylor plant and the Pyeongtaek campus in South Korea, though Pyeongtaek’s construction is still ongoing.

Additionally, to meet rising AI-driven demand, some facilities originally planned for foundry production at Pyeongtaek have been repurposed for memory manufacturing, making external observers more sensitive to resource allocation and ramp-up pace at Pyeongtaek.

Profitability target for 2026: foundry business turnaround tied to capacity ramp-up

The pace of Taylor’s ramp-up and 2nm process introduction are seen as key to improving Samsung’s foundry business. According to ET News, Samsung aims to restore profitability in its semiconductor foundry division by 2026.

Citing industry sources, ET News reports that Samsung’s Device Solutions (DS) division is targeting a profit turnaround in Q4 2026, a schedule that is at least a year earlier than last year’s plan, which aimed for profitability and a 20% market share by 2027.

Within this framework, any deviations in Taylor’s mass production timeline or 2nm deployment could influence market perceptions of the foundry’s recovery path.
