MediaTek raises bid for a larger share of custom AI chips, aiming at 15%-20% of a projected $80 billion 2027 market

MediaTek is pressing its advantage in custom artificial intelligence chips, setting a higher target for how much of the market it expects to capture by 2027. In an update referenced by Yahoo Finance, the company said it now aims to secure 15% to 20% of what it described as an estimated $80 billion custom AI-chip market in 2027.

The custom AI chip segment generally refers to processors and accelerators designed specifically for a particular customer’s workloads, rather than generic off-the-shelf hardware. For large cloud and AI operators, custom silicon is often pursued to improve performance per watt, manage power and cost, and tailor hardware to rapidly changing models and deployment patterns.

MediaTek also said its first AI accelerator for a major U.S. cloud provider will enter production in the fourth quarter, according to the same report. An accelerator is the specialized processing component used to speed up AI training and inference, typically by handling matrix operations and other compute-heavy tasks more efficiently than general-purpose CPUs.

The competitive framing in the Yahoo Finance piece suggests a shift in momentum among suppliers of custom AI silicon, with Alphabet positioned as a potential winner and Broadcom as a firm that could fall behind. However, the available information here does not include additional detail on what, specifically, would cause Broadcom to lose share, or what role Alphabet would play beyond being referenced in the competitive dynamic.

For Alphabet, the opportunity is tied to its broader effort to supply AI infrastructure for its own cloud operations and services, where custom hardware can become part of the stack used to run large-scale AI workloads. If more cloud providers choose custom silicon, the vendor landscape tends to expand and then narrow, depending on execution timelines, yields, packaging and supply capacity, and how quickly designs can be iterated.

For MediaTek, the raised target indicates confidence that demand for custom accelerators is continuing to strengthen and that the company can translate partnerships into production volume at scale. The July 31 update also indicates that MediaTek is treating the 2027 window as a key milestone for reaching a meaningful share of a market it estimates at $80 billion.

Even with the stated targets and the planned production start, several elements remain unclear from the information available in this packet. The update does not specify which “major U.S. cloud provider” is involved, what performance or power benchmarks MediaTek is targeting for its first accelerator, or how the company expects to match competitors on cost, delivery schedules, and manufacturing capacity.

What to watch next is whether MediaTek and its cloud partner(s) provide more concrete milestones as the fourth-quarter production window approaches, including any details on ramp-up timelines and which classes of AI workloads the accelerator is designed to serve. Additional disclosure on custom-chip demand, especially pricing and supply agreements, would also help clarify whether the 15% to 20% goal is likely to be met.
