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.
Reported Nvidia investment
An investment by Nvidia of $3.5 billion in convertible bonds issued by MediaTek, alongside an arrangement for MediaTek to produce Nvidia's NVLink Fusion chiplets, switches and custom memory, became public on 31 August 2026. The report rests on a single subscription briefing whose body could not be retrieved, and the claim is not verified beyond that account (Source: theinformation.com).
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.
