U.S. stock futures fell Wednesday morning as surging oil prices rekindled inflation fears and investors positioned for a heavy night of Big Tech earnings.

Futures on the tech-heavy Nasdaq 100 dropped about 0.7%, leading the pullback. S&P 500 futures eased around 0.3% and Dow Jones Industrial Average futures slipped roughly 0.1%. The moves point to a soft open on Wall Street after a chip-led rally on Tuesday.

Two forces are driving the pre-market tone: a sharp move higher in crude, and caution ahead of results from Alphabet and Tesla, both due after Wednesday’s closing bell.

Oil surge puts inflation back in focus

Crude prices led the overnight story. Brent crude jumped about 4% to around $94 a barrel, its highest in more than a month, while U.S. West Texas Intermediate climbed close to $88. The catalyst was fresh geopolitical risk: the move followed another round of overnight U.S. military strikes on Iran, and Secretary of State Marco Rubio said Tehran was “not serious about talks.”

For markets, the concern is less about supply today and more about what higher energy costs do to inflation. A sustained climb in crude feeds directly into headline prices, and that complicates the path for interest rates. Traders looking for context on how much of the world’s oil sits at stake can review how much oil Iran actually holds and why disruptions there ripple across global benchmarks.

Bonds and the Fed backdrop

The rates picture stayed firm. The yield on the 10-year U.S. Treasury note rose to 4.63% on Tuesday, holding above the 4.6% mark, according to Treasury Department data. Higher yields tend to weigh on richly valued growth and technology names, which helps explain why the Nasdaq is leading the downside.

The Federal Reserve is now in its customary blackout period ahead of next week’s policy meeting. According to the Fed’s official calendar, the Federal Open Market Committee meets July 28-29, with the rate decision due Wednesday, July 29. Policymakers are widely expected to leave the federal funds rate unchanged, but futures markets are pricing tighter policy later in the year, with traders assigning roughly a 68% chance of a rate increase at the September meeting. An oil-driven inflation scare only reinforces that hawkish lean.

The main event: Alphabet and Tesla after the close

The session’s biggest swing factor lands after hours. Two members of the “Magnificent Seven” report on the same evening, and both speak to the health of the AI trade that has powered this market. Investors worried about concentration risk in those names can look at S&P 500 ETFs built to sidestep the Magnificent Seven.

For Alphabet, the focus is on Search and Google Cloud. Analysts remain broadly bullish, expecting cloud demand and resilient advertising to keep revenue growth above 20%. The question is whether heavy AI capital spending is starting to pressure margins.

For Tesla, the story is margins over volume. The company reported record second-quarter deliveries of 480,126 vehicles, up about 25% from a year earlier. Yet Wall Street consensus sits near $0.52 a share on roughly $26 billion in revenue, with analysts flagging that price competition and softer average selling prices could cap profitability even as unit sales climb. Commentary from chief executive Elon Musk on robotaxis, energy storage, and full self-driving will likely matter more to the stock than the headline numbers. For investors weighing broader exposure to the theme rather than a single name, AI-focused ETFs offer a diversified route.

What to Watch for the Open

  • Oil: Watch whether Brent holds above $90. A further leg higher keeps inflation and the Fed’s hawkish tilt front and center.
  • Yields: The 10-year Treasury above 4.6% is a headwind for tech. A break higher would pressure growth stocks further.
  • Earnings after the close: Alphabet on cloud and ad growth; Tesla on margins and Musk’s forward guidance. Both will set the tone for Thursday’s session.
  • Breadth: Tuesday’s rally leaned on semiconductors. If chips cool alongside the Nasdaq, the pullback could broaden.

The setup is a market caught between a firm rates backdrop, an energy shock it did not expect this week, and two earnings reports that could either confirm or crack the AI narrative. By Thursday’s open, traders should know a lot more about all three.
