US stock futures slump, oil jumps after Iranian media reports explosions on Kharg Island

Stocks returned to negative territory in premarket trading and oil futures jumped after Iranian state-sponsored media said that explosions were heard on Kharg Island.

The Mehr News Agency, which reported this at 6:25 a.m. ET, did not comment on the source of these explosions. Fox News reported that the US targeted military installations, and unintentionally hit a landing dock. Axios also reported that the strikes were intended to hit military targets, citing a US official.

The SPDR S&P 500 ETF turned from slightly positive to down about 0.5% in the wake of this report, and extended losses after President Donald Trump posted on Truth Social that “a whole civilization will die tonight.”

West Texas Intermediate crude oil futures traded about 3% higher to $116 per barrel after having previously been roughly flat.

Trump’s Tuesday morning post seemingly reaffirms his commitment to escalate attacks on Iran, including targets that can be considered war crimes, if the Strait of Hormuz is not reopened. His current deadline, which has previously been pushed back on multiple occasions, is 8 p.m. on Tuesday night.

On Sunday, the president’s Truth Social account posted that “Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran.”

Kharg Island handles roughly 90% of Iran’s crude exports. Strikes that reduce Iran’s ability to ship oil would further disrupt energy markets, which have been roiled by the war and the limited movement of tankers through the Strait of Hormuz, a key choke point. Initial US attacks on Kharg Island in March were said to have hit military sites rather than energy infrastructure.

Samsung’s massive Q1 fails to lift Sandisk, other data center plays

Almost all memory stocks slipped Tuesday, despite getting a positive update on the massive flood of money pouring into the sector from the AI build-out, as the potential escalation of the US war with Iran Tuesday evening overshadowed Samsung’s blowout numbers.

Korean chip giant Samsung Electronics reported preliminary Q1 results showing operating profit up by 755% compared to Q1 2025, trouncing pretty elevated expectations for a gain of about 550%.

Samsung is the world’s largest producer of NAND and DRAM chips. Once considered low-value commodity inputs to tech products, NAND and DRAM prices have exploded over the last six months amid a hyperscaler scramble to secure chips that can manage the surfeit of data produced by AI.

The same dynamics have made memory plays like Sandisk, Western Digital, and Micron some of the best-performing stocks in the S&P 500 over the last 12 months.

But other than Seagate Technology Holdings, those stocks were down Tuesday as of 11:15 a.m. ET, as the surge in oil prices and ongoing war with Iran muted much of the AI data center trade excitement. Bellwethers like Nvidia and hyperscalers like Oracle and Meta were struggling early, as were data center input makers like Corning and Coherent, AI power plays like GE Vernova, Vertiv Holdings, and even hard-hat builders of the shells that house all those AI servers.

On the other hand, some so-called optical stocks — makers of fiber-optic connections that quickly shift data between users, hyperscalers, and all around data centers themselves — were up. Lumentum and Arista Networks, two popular optical stocks, were showing resilience.

Paramount surges on bullish options activity, 1 day after $24 billion Gulf backing report

Paramount Skydance shares surged more than 9% shortly after markets opened on Tuesday, on pace for their best day since news that the company had emerged victorious in the Warner Bros. bidding war broke in late February.

The entertainment giant is being propelled by bullish options activity, with about 17,000 call options having changed hands as of 10:03 a.m. ET, already ahead of the 20-day average for a full session.

The market move comes a day after reports that three Gulf sovereign wealth funds would back Paramount’s offer for WBD to the tune of $24 billion. Those working on the deal don’t expect the Gulf funds’ involvement to spark any additional regulatory reviews.
