Broadcom and TSMC Emerge as ‘Big Winners’ in Custom AI Chip Boom

Broadcom (NASDAQ:AVGO | AVGO Price Prediction) and Taiwan Semiconductor Manufacturing (NYSE:TSM) are emerging as major beneficiaries of the custom AI chip boom, capturing value alongside NVIDIA’s continued dominance in the AI infrastructure market.

Broadcom just reported Q1 FY2026 revenue of $18.02B, up 28% year-over-year, with AI semiconductor revenue surging 74%. The company’s Q1 FY2026 guidance projects AI semiconductor revenue will double year-over-year to $8.2B, driven by custom AI accelerators and Ethernet AI switches. With 188% earnings growth in its most recent quarter and consistent gross margins around 68%, Broadcom is demonstrating exceptional pricing power as hyperscalers build proprietary chip architectures.

TSMC’s role as the manufacturing backbone is equally critical. The foundry giant posted Q4 2025 revenue of $33.73B, up 20.5% year-over-year, with 77% of wafer revenue coming from advanced 7nm and below processes. The company’s 3nm node captured 28% of wafer revenue while 5nm took 35%, reflecting strong demand for cutting-edge AI chip manufacturing. TSMC’s 45% profit margin and 54% operating margin showcase the profitability of serving AI infrastructure buildouts.

The custom chip trend represents a strategic shift. Rather than relying solely on NVIDIA (NASDAQ:NVDA)’s off-the-shelf GPUs, companies like Alphabet (NASDAQ:GOOGL), Amazon (NASDAQ:AMZN), and Meta Platforms (NASDAQ:META) are designing specialized accelerators optimized for their specific workloads. This creates sustained demand for both chip designers like Broadcom and advanced manufacturers like TSMC.

With TSMC guiding Q1 2026 revenue between $34.6B and $35.8B and Broadcom projecting $19.1B, both companies are positioned to capture growing wallet share as AI infrastructure spending accelerates. The custom chip boom isn’t replacing NVIDIA’s dominance, but it’s creating parallel revenue streams that benefit the entire semiconductor ecosystem.
