Breaking: Samsung foundry Aims For 60–70% fab Utilization This Year as Tesla AI Chips Move Toward Mass production
Samsung Electronics’ contract semiconductor unit, known as the Foundry, is accelerating plans to lift factory utilization to between 60% and 70 within 2026. The push comes as the firm ramps up a high‑stakes AI chip supply relationship with Tesla, a move viewed as a strategic step to spread fixed costs and improve profitability while competing with TSMC on advanced nodes such as 2nm.
Utilization Target Signals a Deliberate Profitability Play
Industry observers say the current rate, which stood at about 50% last year, is expected to top 60% in the first half of 2026 and could exceed 70% by year’s end.The emphasis is on sustaining production lines, boosting yields, and taking on additional orders around mature process technologies to shore up margins.
Key Wins and a Growing Client Pipeline
Beyond Tesla, Samsung Foundry has snagged a supply deal for NVIDIA’s 8‑nanometer GPUs used in a Nintendo‑Japan game console project. It has also secured a supply relationship for Intel’s Platform Controller Hub. The combination of recent wins with Tesla and other big-tech customers is helping to stabilize internal operations and diversify revenue streams.
Profitability Snapshot: Memory Remains Big, Foundry Narrowly Trails
In the third quarter of last year, Samsung’s DS (Device Solutions) division posted a trading profit of roughly 7 trillion won. The Memory division earned about 7.7 trillion won,while the Foundry and System LSI unit recorded a deficit of around 700 billion won. For the fourth quarter, memory profits are anticipated to climb to about 18 trillion won, while non‑memory losses are estimated at 1 trillion to 1.5 trillion won. The improving trajectory contrasts with quarterly losses of over 2 trillion won seen earlier in the year, signaling a material shift toward broader profitability.
Tesla’s AI Chip roadmap: AI5 to AI6, Mass Production Targeted for 2028
Tesla has outlined plans for a new AI chip family, with AI5 entering production cycles and AI6 moving toward mass manufacture. The design phase for AI6 reportedly began after a 23 trillion won AI6 supply contract was signed with Tesla last year. with an approximate design cycle of nine months, the AI6 project could reach mass production around 2028. While AI5 productions might potentially be narrower in scope, the program is expected to serve as a critical benchmark for advanced process capabilities across the market.
Industry Perspective: Samsung’s “Second-Best” narrative and Strategic Focus
Some observers argue that Samsung’s current strategy—prioritizing profitability and utilization gains—will slow the pace of flagship node development but creates a sustainable bridge toward larger market leadership. A prominent industry voice notes that the company’s share of the foundry market has expanded significantly in recent years, suggesting a deliberate approach to narrow the gap with the leader. The FT has highlighted a view that Samsung benefits when the top supplier is unavailable, underscoring the competitive importance of the foundry ecosystem as demand for cutting‑edge silicon continues to evolve.
Competitive Edge: Efficiency, Yields, and a broader Customer Base
Executives say the guiding principle is to improve profitability by pushing utilization higher and securing a diverse client base, including tech giants like Google and AMD that are already in discussions. If the Tesla program proves its worth in real‑world performance, it could prompt customers previously deprioritized by the market leader to consider Samsung’s foundry services, especially as the industry gears up for 2nm and beyond.
| Metric | Current/Last Year | Target | Timeline / Notes |
|---|---|---|---|
| fab utilization | About 50% | 60–70% | H1 2026: >60%; End of 2026: >70% |
| Major contracts | Tesla AI chip; NVIDIA GPUs for Nintendo; Intel PCH | Expanded multi‑customer base | Tesla AI5/AI6 pipeline; other big‑tech discussions ongoing |
| Profitability focus | Deficits in Foundry unit in prior quarters | Improved profitability via higher utilization and yields | Shift toward mature processes to secure steady revenue |
What these moves mean for the AI silicon race is still unfolding. samsung’s ability to convert elevated utilization into sustained profitability will hinge on the Tesla program’s success, the ability to scale AI‑oriented designs, and how quickly it can advance toward 2nm and beyond to compete on the most advanced nodes.
