US Stock Futures Slide as Broadcom Earnings Miss Sparks Chip Stock Selloff
US stock index futures fell Wednesday evening as investors digested Broadcom’s mixed results and rising US-Iran geopolitical risks. S&P 500 futures fell 0.5% to 30,410 and Nasdaq 100 futures 0.7% to 30,406.5. Broadcom reported Q2 revenue of $22.19B vs $22.27B expected and guided AI chip revenue to $16B vs $16.36B; shares dropped 12% after hours. Semiconductors weakened amid profit-taking and uncertainty.

Near-term downside risk as AI-chip revenue guidance misses and the market read-through hits semis broadly.
Broadcom reported Q2 revenue below expectations and guided AI chip revenue to $16B vs $16.36B, sending shares down ~12% after-hours.
Bearish bias for the next session(s) with elevated volatility until investors reassess AI demand and competitive positioning.
Background
The piece links a Broadcom earnings/guidance reaction to a broader semiconductor selloff and adds geopolitical risk from the US-Iran conflict.
Why it matters
Broadcom’s revenue/guidance miss drives immediate after-hours selling and increases the likelihood of further semi de-risking in the next session, while geopolitical escalation and higher oil prices add macro pressure.
Market relevance
A single-company AI-chip guidance miss is being treated as a sector read-through catalyst, aligning with broader risk-off in US tech futures.
Market effects
Broadcom’s AI-chip revenue guidance miss is framed as resetting expectations across semiconductor stocks, increasing correlation and volatility.
Primarily US tech/semis; futures weakness suggests spillover into US-listed global chip supply-chain sentiment.
US-Iran escalation is cited as a macro risk factor, with oil higher adding uncertainty for global markets and risk appetite.
Alternative perspectives
Despite the revenue outlook miss, Broadcom maintained its AI chip forecast at $16B and delivered better-than-expected EPS, which could limit downside if investors focus on profitability and longer-cycle AI demand.
The article notes supply-chain constraints at major foundries (TSMC/Samsung) and competitive pressure (e.g., Marvell), which could mean the selloff is partly about near-term capacity/competition fears rather than collapsing AI demand.
