U.S. stock index futures moved higher on Sunday evening as investors welcomed signs of progress in trade discussions ahead of a planned summit between President Donald Trump and Chinese President Xi Jinping. The meeting, scheduled to take place in Washington this week, comes at a sensitive moment for relations between the world’s two largest economies.
Markets also responded to Trump’s comments that he would be open to meeting Iranian President Masoud Pezeshkian during the United Nations General Assembly. However, continued hostilities in the Middle East, particularly involving Yemen’s Iran-backed Houthis and Saudi Arabia, kept geopolitical risks firmly in focus.
Summary
U.S. stock futures advanced as markets looked ahead to the Trump-Xi summit and renewed diplomatic activity surrounding Iran. S&P 500 futures rose 0.35%, Nasdaq 100 futures gained 0.54%, and Dow futures advanced 0.27% during Sunday evening trading.
The positive opening followed a modest recovery on Wall Street, where technology stocks regained some ground after significant losses earlier in the week. Investors also monitored reports that Anthropic had delayed its planned IPO while preparing a new AI model to compete with OpenAI.
Trade negotiations, AI regulation, Middle East tensions and oil-market volatility are expected to remain important drivers of market sentiment throughout the week.
U.S. Stock Futures Edge Higher Ahead of Major Diplomatic Meetings
S&P 500 Futures climbed 0.35% to 7,739.50 points by 22:14 ET (02:14 GMT). Nasdaq 100 Futures advanced 0.54% to 30,079.50 points, while Dow Jones Futures gained 0.27% to 52,220.0 points.
The gains followed a mildly positive Friday session on Wall Street, when technology shares recovered some ground after heavy losses earlier in the week. Semiconductor stocks contributed to the rebound, although investors remained cautious about the broader outlook for artificial intelligence spending and technology-sector valuations.
Markets are now balancing improving expectations for U.S.-China trade relations against continuing geopolitical uncertainty in the Middle East. The upcoming diplomatic meetings could provide further clarity on tariffs, AI cooperation and the prospects for reducing regional tensions.

Anthropic IPO Delay Keeps AI Stocks in Focus
A Wall Street Journal report over the weekend indicated that artificial intelligence company Anthropic had delayed its planned initial public offering from October to November. The revised timeline would give the company additional time to present its third-quarter financial results to prospective investors.
Earlier reports suggested that Anthropic could seek a valuation of approximately $2 trillion, although the proposed valuation and listing schedule remain subject to change. The offering would represent a major test of investor appetite for privately held AI companies as competition intensifies across the industry.
Reuters also reported that Anthropic was considering releasing a new AI model ahead of its planned IPO. The system would compete with OpenAI’s Astra model, adding another dimension to the rivalry between two of the most prominent developers of frontier artificial intelligence systems.
The developments come as investors increasingly examine whether strong demand for AI services can translate into sustainable revenue growth and profitability. Anthropic’s financial performance, product launches and IPO preparations could therefore influence broader sentiment toward AI-related technology companies.

U.S.-China Trade Talks Begin Ahead of Trump-Xi Summit
Markets were encouraged by the start of discussions between U.S. and Chinese officials ahead of the planned meeting between Trump and Xi later this week.
U.S. Treasury Secretary Scott Bessent met Chinese Vice Premier He Lifeng in New York City on Sunday to discuss the economic relationship between the two countries. The talks were intended to prepare the ground for the presidential summit and identify areas where further progress might be possible.
Trump and Xi are scheduled to meet in Washington on Thursday, September 24, marking the Chinese president’s first state visit during Trump’s second term. The U.S. president had previously visited Beijing earlier this year, and the latest meeting represents another opportunity to address unresolved economic and technological disagreements.
Tariffs and AI Regulation Remain Central Issues
Trade relations between the United States and China remain strained despite ongoing diplomatic engagement. Washington’s tariffs on Chinese goods are expected to feature prominently in the discussions, particularly as the existing trade truce approaches its scheduled expiration in early November.
Artificial intelligence is also becoming an increasingly important part of the bilateral relationship. Both countries are major players in advanced AI development, making questions surrounding technological competition, regulation and national security relevant to the upcoming talks.
Bessent said following Sunday’s discussions that the two sides had examined the possibility of establishing a U.S.-China AI dialogue. The proposed framework would improve communication on certain AI-related security concerns, although the broader trade and technology disagreements remain unresolved.
Trump Signals Openness to Meeting Iran’s Pezeshkian
Middle East developments remain another important factor for financial markets after the United States and Iran exchanged renewed warnings over the weekend.
According to a Fox News report, Trump said he was open to meeting Iranian President Masoud Pezeshkian during the United Nations General Assembly in New York. The comments raised the possibility of direct diplomatic engagement, although neither side had announced an agreement to hold such a meeting.
Trump also warned that Iran could face severe economic and political consequences if it failed to reach an agreement with Washington. Tehran, meanwhile, warned that any renewed U.S. military attacks would be met with sustained retaliation.
The contrasting messages highlight the uncertain diplomatic environment surrounding the conflict. While the possibility of negotiations remains open, the military situation continues to create risks for regional stability and international energy markets.
Houthi Attacks on Saudi Arabia Add to Regional Tensions
The latest diplomatic developments followed renewed missile and drone attacks by Yemen’s Iran-backed Houthi movement against Saudi Arabia. The group reportedly targeted Riyadh over the weekend while continuing operations that threaten regional security and shipping around the Bab el-Mandeb Strait.
The waterway connects the Red Sea with the Gulf of Aden and represents an important route for international trade and energy shipments. Military activity in the surrounding region can affect shipping costs, insurance premiums and the willingness of commercial operators to use the route.
The New York Times reported that Trump had declined Saudi requests for U.S. strikes against the Houthis, with the administration reportedly concerned about opening another front in the wider conflict involving Iran.
Oil prices remained volatile late Sunday as traders assessed the possibility of further escalation. Continued instability around regional shipping routes could keep energy markets sensitive to military and diplomatic developments throughout the week.
What Investors Should Watch This Week
The Trump-Xi summit will be an important event for investors monitoring international trade, technology regulation and relations between the world’s two largest economies. Any concrete agreements on tariffs or AI-related cooperation could influence market expectations, although the existing disagreements remain substantial.
Developments surrounding Iran will also deserve attention, particularly whether the possibility of a Trump-Pezeshkian meeting leads to further diplomatic engagement. Continued Houthi attacks or additional military escalation could maintain pressure on energy markets and international shipping.
Meanwhile, technology investors will be watching Anthropic’s IPO preparations and the company’s reported plans for another frontier AI model. Together, these developments highlight a week in which trade policy, artificial intelligence and geopolitical risk are likely to remain closely connected in financial-market sentiment.
