MediaTek's Q2 2026 mobile revenue fell approximately 20% year-over-year as global smartphone shipments remain weak, making the data-center pivot urgent .
MediaTek is using TSMC's advanced packaging (CoWoS for training-focused chips) and is also working on test chips with TSMC's upcoming A14 process. It has indicated plans to use TSMC's Arizona fabs for 4nm and 3nm production .
The move directly challenges Broadcom and Qualcomm in the custom AI ASIC market for cloud providers. Broadcom currently dominates custom AI accelerators for hyperscalers, while Qualcomm is also pushing into data-center AI . MediaTek's $5 billion war chest and existing TSMC relationship position it as a serious contender for next-generation cloud AI contracts.
MediaTek is transforming from the world's largest smartphone chip supplier into a broad-based custom AI ASIC house, targeting the fast-growing hyperscaler market where cloud providers are increasingly designing their own silicon .
