MediaTek is a Taiwanese fabless semiconductor company, historically the largest supplier of mobile system-on-chip designs outside Qualcomm, that has moved into designing custom AI accelerators for data-center customers. Its data-center business is a second growth line set against a declining mobile-chip segment: mobile-chip revenue fell 20% year on year in the second quarter of 2026, while the company expects more than $2 billion of data-center AI chip revenue in 2026 (Source: reuters.com).

Custom AI accelerator programme
CEO Rick Tsai said on July 31, 2026 that MediaTek's first custom AI chip enters production in the fourth quarter of 2026, and that a second remains on track for volume production in 2028. The board's approval of a $5 billion discretionary financing budget on the same date is directed at this programme (Source: reuters.com).
MediaTek raised both its estimate of the market and its ambition within it on the same date, lifting the 2027 custom-AI-chip addressable market to $80 billion from a prior range of $70–80 billion and its target share to 15–20% from 10–15%. The company did not state a corresponding revenue target. Custom accelerators designed for a single large buyer are the segment through which hyperscalers reduce dependence on merchant GPUs; see Semiconductor Supply Chain and Broadcom, the largest incumbent in custom-accelerator design.
Open questions
- The customers for the first and second custom chips were not named in the available reporting.
- The form the $5 billion discretionary financing would take — debt, equity, or a mix — is described only as a budget approved by the board.
Relationships
- related: Broadcom — the established custom-accelerator designer MediaTek's programme competes with.
- related: Nvidia & TSMC — AI Compute Infrastructure — the merchant-GPU incumbent whose share custom accelerators address, and the foundry Taiwanese fabless designers depend on.
- related: Semiconductor Supply Chain.
- related: AMD — Advanced Micro Devices — another merchant alternative in data-center accelerators.
