Broadcom Earnings: AI Chip Sales Tripled. Here’s the $34.8 Billion Number Investors Need to Watch.

Broadcom reported Q3 2026 revenue of $29.59B (+86% YoY) and adjusted EPS of $3.32, both beating Street targets, with AI-chip revenue surging to $16.7B (+221% YoY). Management guided Q4 revenue to $34.8B versus the $35.03B consensus (a ~$0.23B, ~0.7% miss), which spooked investors despite $21.7B expected AI-chip revenue and $13.7B free cash flow. The setup remains highly dependent on maintaining AI-driven growth and margins given the stock’s steep valuation.

Analysis

AVGO is now being priced less like a cyclical semiconductor winner and more like a quasi-infrastructure utility with perpetual acceleration. That is dangerous because the market has shifted from rewarding beat-and-raise to penalizing any hint that the AI revenue curve is merely strong instead of inflecting harder; at this multiple, the stock behaves like a duration asset, so small changes in the slope of growth can drive outsized multiple compression.

The more important second-order issue is customer power. Large hyperscalers are learning to split custom silicon across vendors to preserve bargaining leverage, which can cap long-run pricing and eventually force AVGO to concede margin to defend share. That is modestly constructive for MRVL on a relative basis, but only if it can prove socket wins; otherwise the real winner is the customer, not the vendor, because procurement fragmentation lowers unit economics across the supply chain.

Near term, this is more a sentiment reset than a fundamental break, and the key catalyst is not the current quarter but the next one or two guideposts on gross margin and AI mix. If management can keep margins stable while AI continues to accelerate, the selloff is likely an overreaction; if AI growth remains strong but guide precision degrades, the stock can de-rate quickly despite excellent fundamentals. The contrarian view is that the market is overfitting to a sub-1% miss in a business still compounding at exceptional rates; the real bearish signal would be evidence of customer defection or margin leakage, not a tiny guide shortfall.

Key Decisions for Investors

• Short AVGO on any post-earnings bounce; target a 1-3 month horizon for multiple compression if investors keep treating slight guidance variance as a failure. Risk/reward improves if the stock reclaims only a portion of the gap but fails to regain momentum.
• Buy a defined-risk AVGO put spread 1-2 quarters out to express the ‘perfection premium’ risk; thesis works if forward guide or gross margin commentary softens, and is falsified by another quarter of reacceleration plus stable margins.
• Relative value: long MRVL / short AVGO for 3-6 months as a second-sourcing trade. This only works if hyperscalers keep diversifying custom silicon; cut the trade if MRVL fails to win visible design wins or if AVGO reasserts pricing power.
• Watch GOOGL as the customer-side beneficiary of vendor diversification rather than as a direct earnings winner. If Google continues to multi-source AI silicon, it strengthens negotiating leverage across the ecosystem and weakens the premium embedded in single-supplier narratives.
