Dow futures climb 250 points: 5 things to know before Wall Street opens

US stock index futures climbed to record highs on Tuesday, putting Wall Street on course for a stronger open as investors looked past volatile energy markets and focused on signs of progress in US-Iran peace talks.

The advance was also powered by fresh gains in AI-linked chipmakers, which have remained at the centre of this year’s equity rally.

Brent crude stayed choppy as traders assessed the risk of disruption in the Strait of Hormuz, but the broader mood in futures markets suggested investors were still willing to bet that geopolitical tensions would ease rather than spiral further.

5 things to know before Wall Street opens

1. US futures point to a record open

The futures market suggest investors are preparing for another strong session after major US indices pushed to record levels last week.

Dow Jones Industrial Average futures rose 255 points, or 0.51%. S&P 500 futures climbed 0.62%, while Nasdaq-100 futures advanced 0.95%.

2. Iran talks support risk appetite

The market’s brighter tone was partly driven by hopes that negotiations between the US and Iran could reduce the risk of a broader conflict.

US Secretary of State Marco Rubio said reaching a deal with Iran could “take a few days.”

President Donald Trump also said talks were going “nicely” in a post on Monday, helping calm some concern that recent tensions could escalate.

3. Oil remains the biggest wild card

Energy markets, however, remain far from calm.

Brent crude rose as much as 3% as traders continued to assess uncertainty around shipping access through the Strait of Hormuz.

The waterway remains a critical route for global oil flows, meaning any disruption could quickly feed into energy prices and inflation expectations.

For Wall Street, oil’s volatility matters because a sustained price spike could complicate the Federal Reserve’s rate outlook.

Higher energy costs can keep inflation sticky, making it harder for policymakers to justify cutting rates or shifting to a more dovish stance.

4. AI chipmakers lead premarket gains

Semiconductor shares were among the strongest performers before the open as enthusiasm around artificial intelligence continued to drive investor demand.

Marvell Technology rose 5.7% in premarket trading, while Micron and Intel gained about 2% each.

Chip stocks have been a central pillar of the broader US market rally, with investors betting that AI-related spending will continue to support revenue growth across the semiconductor supply chain.

5. Earnings and the Fed stay in focus

Beyond geopolitics and AI, investors are still watching corporate earnings and Federal Reserve signals for clues on whether the rally can continue.

Wall Street’s record highs have been supported by strong earnings, particularly among large technology companies.

But the next leg of the rally may depend on whether profit growth broadens beyond the AI leaders.

The Fed remains another key risk. If oil prices stay elevated, inflation worries could return, limiting the central bank’s room to ease policy.

That could challenge equity valuations, especially in growth sectors where higher rates tend to weigh more heavily.
