Broadcom delivered crushing fourth-quarter results with AI chips revenue jumping 74% to $6.5 billion and total revenue reaching $18 billion. But the stock plunged over 10% after CEO Hock Tan warned that higher AI sales would compress gross margins. The company revealed an $11 billion custom chip deal with Anthropic and projected AI revenue to double to $8.2 billion next quarter, yet investors questioned whether rapid growth justifies stretched valuations.

Why This Matters for AI Infrastructure

Broadcom's performance signals that demand for AI infrastructure spending shows no signs of slowing, even as investors question how quickly these investments will translate into profits. The company's success with custom AI chips demonstrates a viable alternative to Nvidia's dominance in GPUs, as application-specific integrated circuits offer higher performance for specific workloads

2

. Newman noted that Broadcom likely controls 70% to 80% of the custom silicon market because few rivals can match its design capabilities

2

. VMware Cloud Foundation also contributed significantly, with infrastructure software revenue growing 26% to $27 billion for the year

5

. The company raised its annual dividend by 10% to $2.60 per share, citing robust cash generation

4

. Watch for how Broadcom manages the tension between rapid revenue guidance improvements and margin compression as the custom chip mix increases throughout fiscal 2026.
