Broadcom locks multi-year TPU deal with Alphabet, Anthropic; 3.5 GW capacity from 2027

Broadcom and Alphabet announced extended agreements to develop and supply custom Tensor Processing Units (TPUs) and AI networking components through 2031, cementing one of the most consequential custom silicon relationships in AI infrastructure. The deal encompasses both a long-term product roadmap for future TPU generations and a multi-year supply commitment for interconnect and optical components used in Google's next-generation AI racks. The long-term structure extends revenue visibility far beyond typical semiconductor cycles.

The partnership expands to include Anthropic, granting the Claude maker access to approximately 3.5 gigawatts of next-generation TPU-based AI compute capacity beginning in 2027. Anthropic's revenue run rate has surpassed $30 billion (as of April 2026), and the startup has already placed $21 billion in TPU orders ($10B in Q3 2025 for Ironwood, $11B in Q4 for 2026 delivery). Broadcom disclosed a $73 billion AI backlog overall and is targeting $100 billion in annual AI chip revenue by 2027; the Anthropic component alone represents an estimated $21–42 billion in potential annual revenue once 3.5 GW comes online in 2027.

The technical division of labor splits TPU design between Broadcom (TPU 8t, the training-optimized variant) and MediaTek (TPU 8i, the inference-optimized variant), both to be manufactured on TSMC's 2nm process with late-2027 availability. This deliberate competition among design partners reflects Google's strategy to manage costs while maintaining differentiation versus Nvidia's general-purpose GPU dominance. Broadcom's role as silicon implementer—converting Google's architecture into manufacturable layouts and managing power and packaging—is where margin and strategic value reside.

For architects: this deal validates hyperscaler custom silicon as a permanent feature of AI infrastructure spending. TPU demand now has named multi-year commitments from both Google's internal workloads and a major external customer (Anthropic) that grows at 3—10x rates. Broadcom's $73B backlog and path to $100B AI revenue by 2027 suggest that ASIC orders from hyperscalers and their AI customer tier now exceed merchant GPU competition in volume and margin trajectory.
