U.S. stock futures trend higher early Thursday as investors anticipate a positive start to the final quarter of 2026. Polymarket prediction data reflects an 85% probability that the S&P 500 will open higher on October 1.

Market drivers and geopolitical context
Traders are monitoring several key factors influencing sentiment:
- Geopolitics and energy: Iran announced receipt of a U.S. response to its proposal aimed at resurrecting the collapsed Gulf ceasefire. This coincides with the withdrawal of the final U.S. troops from Iraq, 23 years after the invasion. Energy prices extended their slide, with Brent crude dropping 1.19% to $96.86 a barrel and WTI crude falling 1.40% to $89.15 a barrel.
- Fed developments: President Donald Trump called for former Federal Reserve Chair Jerome Powell to resign or face a lawsuit over cost overruns related to the renovation of the Fed’s Washington headquarters. The Fed’s inspector general cited significant project-management deficiencies but found no criminal or administrative misconduct.
- Economic data: Weekly initial jobless claims are due at 8:30 am ET, followed by September’s ISM manufacturing PMI and August’s construction spending data at 10:00 am ET.
Divergence in market breadth
While AI-adjacent stocks helped the Nasdaq Composite post a nearly 3% gain in September, broader market breadth remains exceptionally poor. The Dow Jones ended the month down over 3%, while the small-cap Russell 2000 fell over 4%.
David Morrison, Senior Market Analyst at Trade Nation, noted this divergence highlights a severe lack of confidence in U.S. corporates outside the artificial intelligence ecosystem. Additionally, the yield on the 10-year Treasury Note spiked 81 bps in the third quarter, its steepest rate of increase since 2022. Morrison warns that at current levels, investors might begin shifting exposure away from highly valued equities into Treasuries, though momentum in the AI sector is currently keeping that rotation at bay.

How might the escalating legal threats against the Federal Reserve impact long-term investor confidence in central bank independence and bond market stability?
Will the successful U.S.-Iran ceasefire negotiations lead to a sustained decline in energy prices, or are geopolitical risks still priced into the current crude oil volatility?
Can the AI sector's momentum continue to mask the severe lack of market breadth, or will rising Treasury yields trigger a broader rotation out of high-valuation tech stocks?
