Wall Street futures mixed today: 5 things to know before the market opens

US stock futures found a tentative bid on Wednesday, but the rebound looked more like a pause than a reset.

After two sessions of selling, investors moved back into parts of the technology complex, helped by gains in memory-chip names before Micron Technology’s results.

The mood was still cautious as the Nasdaq 100 had just suffered a wipeout of more than $1 trillion in market value, while investors were also weighing debt-funded AI spending, a more hawkish Federal Reserve and fragile diplomacy in the Middle East.

For Wall Street, the open is less about relief and more about whether buyers have conviction.

5 things to know before Wall Street opens

1. Futures point to a split start

S&P 500 futures edged up 0.17% and Nasdaq 100 futures rose 0.59%, while futures tied to the Dow Jones Industrial Average slipped 69 points, or 0.13%

The split reflected a market trying to stabilise after a sharp technology-led drawdown, without fully shaking off concerns around valuations and rates.

2. The AI trade faces a credibility test

The previous session’s selloff was centred on semiconductors and AI-linked megacaps. Investors are no longer just buying the growth story.

They are asking whether hyperscalers can keep funding AI infrastructure through debt without pressuring margins, balance sheets or future returns.

That marks a shift from momentum trading to closer scrutiny of cash flows.

3. Micron becomes the bellwether

Micron’s results after the closing bell will be watched as a read-through for memory demand, high-bandwidth memory pricing and the broader AI supply chain.

The stock has surged this year, making the bar unusually high.

Market strategists said a strong quarter may already be priced in, leaving the shares vulnerable if guidance fails to extend the rally.

4. Fed rate risks return to the front

Traders have increased bets on another Fed rate rise by year-end after Chair Kevin Warsh signalled a tougher stance on inflation.

Thursday’s personal consumption expenditures report now carries more weight.

Economists expect inflation to remain well above the Fed’s target, keeping pressure on richly valued growth stocks.

5. Geopolitics remains a background risk

Markets are also tracking conflicting US and Iranian accounts of their peace discussions, including nuclear inspections, access to frozen funds and the Strait of Hormuz.

Any setback could quickly revive energy-market stress.

Among single stocks, Cerebras fell sharply after its first post-IPO report, as investors looked past strong revenue growth and focused on margin pressure.
