Broadcom Warns TSMC Capacity Limits in 2026 Constrain AI Chip Supply; PCBs Spur Multi-Year Contracts
Broadcom says TSMC production capacity is hitting its limits in 2026, constraining AI chip supply and slowing Broadcom’s Physical Layer Products output. Extended bottlenecks in laser components and PCB manufacturing are driving customers to sign three-to-four-year contracts to secure capacity as AI infrastructure demand surges.
1. Broadcom Reports TSMC Capacity Bottleneck
Broadcom’s Physical Layer Products division director Natarajan Ramachandran said TSMC is reaching production capacity limits in 2026, marking a shift from previously ‘infinite’ capacity expectations. This constraint is delaying Broadcom’s AI chip shipments and underscores TSMC’s role as a critical node in advanced chip production.
2. AI Chip Demand Surges
Global demand for AI infrastructure has soaked up much of TSMC’s advanced manufacturing lines, driving capacity utilization to peak levels. The rapid adoption of AI workloads is creating a backlog for new AI chip orders, intensifying the pressure on foundry resources.
3. PCB and Laser Component Constraints
Beyond chips, bottlenecks in laser components and printed circuit board production have emerged, with Taiwanese and Chinese PCB suppliers reporting full order books. These manufacturing constraints are extending lead times across the broader tech hardware supply chain.
4. Shift to Multi-Year Supply Contracts
To mitigate supply risks, many customers are locking in three-to-four-year contracts for chips, PCBs and related components. Suppliers including memory chipmakers are negotiating extended agreements of up to five years to stabilize production planning and revenue forecasts.
