Dow futures plunge 320 points: 5 things to know before Wall Street opens

• Fed rate hike bets have shifted sharply, with markets now pricing approximately 50 basis points of increases by December, reflecting sustained inflation concerns under Chair Warsh
• AI spending sustainability is under scrutiny as companies increasingly rely on debt to fund infrastructure investments while borrowing costs rise, shifting focus from growth to balance-sheet strength
• Micron earnings Wednesday and PCE inflation data Thursday will serve as critical tests for the tech rally, with hot inflation readings likely to deepen pressure on rate-sensitive assets including crypto and gold

Market Summary

Key Market Movements:

U.S. stock futures pointed to significant losses ahead of Tuesday's open, with Dow futures down 319 points (-0.61%), S&P 500 futures declining 1.33%, and Nasdaq 100 futures plunging 2.42%. The selloff extended pressure on megacap technology stocks following global equity weakness.

Main Concerns:

The market faces mounting pressure from rising interest rate expectations, with traders now pricing in approximately 50 basis points in Federal Reserve rate hikes by December under Chair Kevin Warsh. This represents a sharp reversal from earlier expectations and reflects concerns about persistent inflation.

AI sector valuations are under scrutiny as investors question the sustainability of debt-funded infrastructure spending amid higher borrowing costs. The focus has shifted from revenue growth to balance sheet strength, pressuring long-duration growth stocks.

Key Upcoming Events:

• Micron Technology (MU) earnings Wednesday will serve as a critical test for the AI and semiconductor rally, with investors seeking evidence that memory and AI chip demand justifies elevated valuations
• PCE inflation data Thursday, the Fed's preferred gauge, could determine near-term market direction
• PMI business surveys Tuesday will provide insight into June economic activity

Market Implications:

Higher rate expectations and tighter financial conditions threaten rate-sensitive assets including tech stocks, crypto, and gold. The Philadelphia Semiconductor Index recently hit records, making Micron's results particularly significant for confirming AI demand sustainability. A hot inflation print could deepen tech sector pressure, while softer readings might provide limited relief given the hawkish policy outlook.
