Broadcom Drops 14% After AI Chip Guidance Falls Short of the Bull Case

The Catalyst

Broadcom reported Q2 fiscal 2026 results after the close on June 3, and on paper they were excellent: revenue of $22.2 billion, up 48% year over year, with AI semiconductor revenue of $10.8 billion, up 143%. The stock still opened down roughly 13.65% on June 4 and fell as much as ~15% intraday.

The problem was the forward number. Q3 AI chip guidance landed near $16 billion against a Street that wanted closer to $17.2 billion, and that gap — not the quarter itself — is what got sold. When a name is priced for an AI supercycle, a single-billion-dollar shortfall on the segment that *is* the entire thesis is enough to trigger a repricing. Broadcom had rallied into the print; the print didn't clear the bar the rally implied.

Why a Beat Sold Off

Two things turned a beat into a 14% drawdown. First, CEO Hock Tan reaffirmed but declined to raise the $100 billion fiscal-2027 AI semiconductor target. Bulls had treated an upgrade to that number as the base case after the strong Q2; holding it flat read as a tell, even though total Q3 revenue guidance of ~$29.4 billion (up 84%) actually came in above consensus. Second, enterprise software revenue — the VMware-driven half of the business — came in soft versus StreetAccount estimates, removing a cushion.

There was also a fresh sell-side knock: Macquarie downgraded the stock, pointing at Google's in-house chip development as a longer-term threat to Broadcom's custom-silicon franchise. Customer concentration cuts both ways — when a handful of hyperscalers drive your XPU revenue, any signal that one is building more internally lands harder than it would on a diversified name.

The Read-Through

This was a sentiment reset, not a broken story. AI semis still grew triple digits, free cash flow hit a record, and the multi-year backlog Tan described doesn't evaporate because Q3 guidance missed a high whisper number. What changed is the premium: the market had Broadcom priced for serial guidance raises, and got a reiteration instead.

The move didn't stay contained. Micron fell about 7% on the read-through, and the broader AI-semi complex traded heavy — a reminder that AVGO is the cleanest single-name proxy for the custom-silicon capex trade, so its guide sets the tone for the group. On the AVGO HIP-3 perp, the after-hours and regular-session move compressed into a continuous 24/7 mark, which is exactly when these contracts diverge most from a cash close as funding and basis absorb an overnight earnings gap.
