Trump to speak at UN; Alibaba’s new AI chip - what’s moving markets
September 22, 2026
Global financial markets are closely watching developments in U.S. politics, Federal Reserve interest-rate policy, Middle East tensions, artificial intelligence and China’s technology sector. U.S. President Donald Trump is set to address the United Nations General Assembly, while Alibaba has unveiled a new artificial intelligence chip that could strengthen China’s AI ambitions.
Meanwhile, U.S. stock futures were broadly subdued after Wall Street posted a strong rally in the previous session, supported by renewed optimism surrounding artificial intelligence stocks.
Here are the key market-moving developments investors are watching today.
1. U.S. Stock Futures Remain Near Flatline
U.S. stock futures were relatively muted on Tuesday following a strong rally in the previous trading session.
The S&P 500 had its strongest session since August, supported by renewed demand for technology and artificial intelligence-related stocks. Investors continued to focus on developments in the rapidly expanding AI sector and expectations surrounding the next phase of AI adoption.
Dow futures edged lower, while S&P 500 futures and Nasdaq 100 futures remained close to unchanged.
Shares of Meta Platforms, AMD and Intel rallied sharply in the previous session as investors reacted positively to developments in AI technology. Meta's latest AI developments have strengthened expectations that agentic AI could increasingly reach mainstream consumers.
The technology rally also benefited semiconductor companies supplying the processors and infrastructure required for advanced AI applications.
At the same time, easing concerns about Middle East tensions pushed oil prices lower in recent sessions, helping reduce some market concerns about additional inflationary pressure.
The 10-year U.S. Treasury yield also moved lower, as investors assessed the outlook for inflation, Federal Reserve monetary policy and economic growth.

2. Trump to Address United Nations as Markets Watch Middle East Developments
U.S. President Donald Trump is scheduled to address the United Nations General Assembly in New York, with investors closely monitoring his comments on international security, Iran, the Middle East and efforts toward a diplomatic resolution to the ongoing conflict.
The Middle East remains a major factor for global financial markets because further escalation could disrupt energy supplies and increase volatility in crude oil prices.
The situation around key shipping routes is particularly important for oil markets. Developments involving the Strait of Hormuz and Bab el-Mandeb Strait have raised concerns about global crude supply and energy transportation.
Brent crude remains above the $100-per-barrel level, highlighting the sensitivity of oil markets to geopolitical developments.
Any signs of diplomatic progress could potentially reduce geopolitical risk premiums in oil prices, while further escalation could increase concerns over energy supply disruptions and inflation.
For investors, developments at the UN are therefore being watched alongside oil prices, inflation expectations, Treasury yields and Federal Reserve policy.

3. Fed Official Signals Possible Additional Interest Rate Hike
Federal Reserve policy remains another major focus for financial markets.
St. Louis Fed President Alberto Musalem said the central bank may need to raise interest rates again to contain inflationary pressures linked to energy costs and persistent demand.
Musalem argued that inflation risks could remain above the Federal Reserve's 2% target without additional policy restraint.
His comments come after the Federal Reserve recently increased interest rates by 25 basis points, while policymakers' latest projections and comments suggested that another rate increase could remain possible later this year.
Higher interest rates can influence a wide range of financial assets, including U.S. stocks, technology shares, bonds, Treasury yields, the U.S. dollar, gold and cryptocurrencies.
Investors are therefore closely monitoring every Federal Reserve statement for clues about the future path of U.S. monetary policy and interest rates.

4. Alibaba Unveils New AI Chip as China Expands Artificial Intelligence Capacity
China's technology sector is in focus after Alibaba Group unveiled a new artificial intelligence accelerator at its annual Apsara Conference in Hangzhou.
Alibaba CEO Eddie Wu introduced the company's new Zhenwu V900 AI chip, describing it as the company's most powerful AI chip to date.
According to Alibaba, the V900 delivers around three times the performance of its predecessor, the Zhenwu M890. The company also said the chips can be combined into large clusters designed to support the training of advanced AI models.
Alibaba is also planning a major expansion of its data center capacity, highlighting the company's broader ambitions in artificial intelligence, cloud computing and AI infrastructure.
The announcement comes as the global technology industry competes to develop increasingly powerful AI processors and computing infrastructure.
The development could attract further attention to Chinese AI companies, semiconductor technology, cloud computing and data-center investment.
Alibaba shares were also higher, keeping the stock in focus among investors tracking China's technology and AI sectors.
5. Paramount Skydance Settlement Clears Path for Warner Bros. Discovery Deal
The media and entertainment industry is also attracting investor attention after Paramount Skydance reached a settlement with California and 11 other states that had challenged its proposed acquisition of Warner Bros. Discovery.
The settlement removes a major legal obstacle to the proposed $110 billion Warner Bros. Discovery acquisition, potentially clearing the way for one of the largest transactions in the global media industry.
Under the settlement, Paramount would increase domestic film production spending by at least $300 million annually.
The company is also expected to increase film production following completion of the transaction, with additional requirements covering independent productions and blockbuster releases.
The agreement also includes provisions relating to editorial independence at CBS and CNN.
Investors are now watching the next steps in the proposed transaction and its potential impact on the competitive landscape of the U.S. media, streaming and entertainment industries.
