Chips Lead Broad Rally as Markets Shrug Off Iran Strikes; SK Hynix 7x Oversubscribed Ahead of Friday Debut; Dow Still Set to Snap Winning Streak

Market Snapshot (Closing Prices — Thursday, July 9, 2026, 4:00 PM NYC)

Market Sentiment & Technology Sector

Wall Street rallied broadly Thursday, with all three major indices closing higher as investors chose to focus on a resurgent AI-chip trade rather than a second consecutive day of U.S.-Iran hostilities. The Nasdaq Composite led with a 1.30% gain to 26,206.89, the S&P 500 rose 0.81% to a fresh closing high of 7,543.64, and the Dow Jones Industrial Average added 139.02 points (0.27%) to close at 52,487.41. The VanEck Semiconductor ETF (SMH) jumped 2.5%, led by a 4.5% gain in Micron Technology and a 7.6% pop in Sandisk, while Bloomberg reported a broader semiconductor gauge climbing 4% and the Nasdaq 100 adding 1.6%.

The rally's clearest catalyst was overwhelming demand for SK Hynix's imminent U.S. listing: the offering is more than seven times oversubscribed ahead of Friday's debut, according to a Reuters source. Nasdaq president Nelson Griggs told CNBC at the RAISE summit that "there's only two main competitors, Micron and Samsung, there's tremendous demand for their products which usually translates to tremendous demand for the stock." SK Hynix shares themselves rose 5.3% in Asian trading ahead of the listing. Sophisticated ai analysis of the day's price action suggests investors have decisively compartmentalized geopolitical risk from the AI infrastructure story — a genuinely notable divergence given that the U.S. struck roughly 90 targets in Iran overnight. Automated ai trading systems appear to have amplified the chip-sector rally throughout the session, even as oil markets and geopolitical headlines remained genuinely volatile in the background.

Despite today's strength, the Dow remains on track to snap a four-week winning streak — its longest since late 2024 — sitting down nearly 1% for the week. Sherwin-Williams and Home Depot led the index lower this week, each sliding around 5%, while Cisco and Nvidia helped offset losses, both climbing more than 4% week-to-date.

Geopolitics & Global Macro Events

Several threads shaped the session beyond the chip-sector rally:

• Iran Conflict Continues, Markets Look Past It: The U.S. launched airstrikes on roughly 90 Iranian targets overnight, and Iran retaliated by striking targets in U.S.-allied Middle East countries, according to the Associated Press. Despite the escalation, oil prices fell Thursday, erasing some of Wednesday's sharp gains as markets weighed the "bumpy path to Middle East peace." One analyst noted that "the market's fundamental oversupply is large enough to allow for plenty of downside participation once current tensions subside," while flagging risks from potential damage to Middle East energy infrastructure and the possibility Iran tests Trump's patience further.
• Existing Home Sales Miss: Sales of previously owned homes fell 2.4% in June to a seasonally adjusted annual rate of 4.09 million units, missing expectations for a slight monthly gain, according to the National Association of Realtors. NAR Chief Economist Lawrence Yun said continued job gains should support the housing market, while warning that stalled inventory growth could limit progress on affordability.
• Global Markets Rally in Sympathy: Europe's Stoxx 600 closed up 0.8%, with chipmakers ASML (+2.2%), BE Semiconductor (+3.5%), and STMicroelectronics (+4%) leading gains. In Asia, Japan's Nikkei 225 closed 1.4% higher and mainland China's CSI 300 jumped 2.5%, though Hong Kong's Hang Seng slipped 0.5%.
• Paramount Skydance's Antitrust Overhang: Shares fell roughly 8.2% after Reuters reported that several U.S. states are preparing an antitrust lawsuit against the company over its acquisition of Warner Bros. Discovery.
• Notable Decliners: Ionis Pharmaceuticals tumbled nearly 20%, and AstraZeneca fell 6.7% after a disappointing heart-disease drug trial.

SpaceX & Nasdaq-100 Giants Tracker (Market Close)

• SpaceX (SPXC): Shares closed Wednesday at $148.30 and traded up 0.80% to $149.45 in Thursday's premarket session, helped by a record-breaking 36th launch of one of the company's Falcon 9 boosters, which carried 29 Starlink satellites into orbit from Cape Canaveral. In a notable vote of institutional confidence, ARK Investment Management CEO Cathie Wood purchased 153,084 shares of SpaceX on Wednesday across three ARK ETFs (ARKK, ARKQ, and ARKX), a stake worth roughly $22.7 million at Wednesday's closing price. SpaceX now represents 4.27% of the flagship ARK Innovation ETF, making it the fund's sixth-largest holding — a meaningful signal even as the stock continues to digest Tuesday's rocky Nasdaq-100 debut (-6%) and remains well off its post-IPO peak.
• Micron's Mega Capex Signal: In a move with direct read-through for the "Magnificent Seven" and the broader AI infrastructure trade, Micron Technology announced plans to increase spending on new U.S. plants to $250 billion to meet AI-driven demand — one of the largest domestic manufacturing commitments disclosed by any chipmaker this year, and a figure that helped fuel today's sector-wide rally.
• Nvidia: Up more than 4% week-to-date, Nvidia was one of the two Dow components (alongside Cisco) that helped offset this week's broader index weakness, reinforcing its outsized influence on both the Dow and Nasdaq given its market capitalization.
• SK Hynix (Friday Debut Preview): With its U.S. listing over seven times oversubscribed, tomorrow's debut is shaping up as the week's single most important event for gauging genuine investor appetite for continued AI-infrastructure exposure — a verdict that will likely set the tone for chip-sector sentiment heading into next week's CPI report and Fed Chair Warsh's congressional testimony.

Commodities, Currencies & Monetary Policy

Oil pulled back Thursday, giving back some of Wednesday's sharp gains as markets recalibrated around the idea that this week's U.S.-Iran exchanges, while serious, may not represent a full return to the earlier, more disruptive phase of the conflict. Ai futures trading models continued to track the volatile crude tape closely, given how quickly sentiment has swung over just the past 48 hours.

Treasury yields steadied Thursday morning after this week's oil-driven volatility, offering the bond market a moment of relative calm ahead of next week's CPI report and Fed Chair Warsh's congressional testimony. Leading ai quant funds are likely using today's rally to reassess semiconductor-sector risk models following Wednesday's hawkish-leaning FOMC minutes, particularly given Micron's massive new capex commitment. In currencies, the relatively contained oil and yield moves left the dollar without a strong directional catalyst; proprietary ai forex trading models will be watching whether that changes once SK Hynix's debut and next week's inflation data provide fresh input.

Market Outlook for Tomorrow

• SK Hynix's Nasdaq Debut: Friday's highly anticipated listing, already seven times oversubscribed, will be the week's culminating event for the AI-chip narrative — a strong open could extend this week's late rally, while any stumble would echo SpaceX's own rocky index debut.
• Delta Air Lines Earnings: Friday's report will offer a read on travel demand resilience amid this week's oil-price volatility and ongoing Middle East uncertainty.
• Iran De-escalation Watch: Whether the current exchange of strikes stabilizes or escalates further remains the single largest tail risk for markets heading into the weekend; ai algorithmic trading systems remain on high alert for overnight developments.
• Dow's Weekly Streak: With the index still down nearly 1% for the week entering Friday, a strong SK Hynix-driven session could determine whether the Dow's four-week winning streak survives or snaps.
