S&P 500 Futures Fall as Congress Challenges Trump Military Authority While Broadcom Weighs on Tech

The Quick Take

• US stock futures were mixed on Thursday, with S&P 500 and Nasdaq futures falling while the Dow Jones gained.
• The House of Representatives voted to challenge Trump's military authority, adding political uncertainty to market sentiment.
• Broadcom earnings miss weighed on the Nasdaq as AI sector valuations faced fresh scrutiny after the disappointment.

US equity futures presented a mixed picture on Thursday, with S&P 500 and Nasdaq 100 contracts declining while Dow Jones futures gained, reflecting a bifurcation between technology-heavy indices and the more industrials-weighted Dow benchmark. The sessions was shaped by dual headwinds: Congressional action challenging Trump administration military authority introduced a layer of political risk to market positioning, and Broadcom's below-consensus quarterly earnings added fresh uncertainty about whether AI infrastructure spending is translating into proportionate earnings outcomes for chip sector leaders. The divergence between Nasdaq weakness and Dow resilience suggests rotation away from high-multiple technology names toward more value-oriented sectors.

The Congressional challenge to Trump's military authority represents a notable political development with potential market implications for defense contractors, weapons manufacturers, and companies with significant government contract exposure. If congressional resolutions constrain executive branch military spending authority, the defense sector could face budget allocation uncertainty. Meanwhile, Broadcom's earnings miss is creating a reassessment moment for the AI trade — when a bellwether semiconductor name underperforms despite reporting strong AI revenue growth, investors begin questioning whether the earnings power of the AI cycle has been adequately priced into equity valuations across the sector and its adjacent supply chains.

Key data releases to monitor include weekly US initial jobless claims, which will provide a near-term macro health check, and any Federal Reserve commentary following recent economic data that could shift rate expectations. The macro variable determining the S&P 500's near-term direction is the interplay between AI earnings delivery and Congressional/executive policy uncertainty — if tech sector earnings fail to justify premium multiples while policy uncertainty increases, the multiple compression scenario that bears have anticipated could begin to materialize more broadly. Options market implied volatility data and VIX levels are the most immediate sentiment gauge for whether Thursday's mixed open represents a brief consolidation or the start of a broader risk-off episode.
