GOOGL stock fell 1% in premarket trading on Monday, following a breakout week that saw gains of 2.3%, snapping a five-week slide. Alphabet, Inc. is reportedly developing an upgraded version of its TPU v9 AI chip, codenamed Triggerfish, and has selected Taiwan's MediaTek as its exclusive development partner, according to supply chain analyst Ming-Chi Kuo. The new chip is expected to build on Google's existing TPU v9 platform, known internally as Humufish, but with significantly stronger inference capabilities to support next-gen AI workloads such as AI agents and reinforcement learning. Kuo stated that Triggerfish will feature a substantial memory upgrade, including SRAM capacity that is two to three times larger than Humufish and support for next-generation HBM4E memory, compared with HBM4 in the current design. The reported move cements MediaTek's position as one of Google's preferred partners for the TPU v9 and underscores the Taiwanese company's increasing business ties with U.S. Big Tech firms. While Broadcom and Marvell remain dominant in the custom AI silicon market, MediaTek's growing role with Google, Nvidia and Microsoft indicates it is becoming a credible challenger.
