Nasdaq hits record high as markets react to jobs data and bond yields
The Nasdaq Composite reached a new intraday all-time high and a record close on Monday. Market movement remained mixed across other indices as investors weighed a soft September jobs report against rising bond yields. While some futures drifted lower in premarket trading, other indicators trended higher. Traders are currently preparing for the upcoming earnings season during a week expected to be relatively quiet.

Why it matters

US Stocks Fall as AI Safety Fears and Rising Bond Yields Pressure Markets
The Dow, S&P 500, and Nasdaq are trending lower as investors react to artificial intelligence safety warnings and climbing Treasury yields. Market volatility intensified following a leaked Anthropic IPO prospectus and reports of a scrapped OpenAI next-generation model, both of which raised concerns about AI risks. Simultaneously, geopolitical tensions involving the US and Iran have supported higher oil prices. While some indices recently hit records, the major averages now face a losing week as the 30-year Treasury bond yield reached levels not seen since June 2002.
Why it matters
This volatility follows a period where the Nasdaq reached new all-time intraday highs in late September. The shift reflects a growing tension between AI optimism and safety concerns voiced by industry executives. Investors are now balancing these tech risks against macroeconomic pressures from the Federal Reserve and Middle East instability.
What is confirmed
- The Nasdaq Composite reached a new all-time intraday high and closed at a record on Tuesday, September 22.
- The 30-year Treasury bond yield reached levels not seen since June 2002.
- US-Iran tensions and AI safety concerns have contributed to market instability.
Still unconfirmed
- A leaked Anthropic IPO prospectus and a scrapped OpenAI next-generation model raised questions about AI safety.
What to watch next
- September payroll data report
- Federal Reserve interest rate decisions
- US-Iran diplomatic backchannel developments

US Stocks Fall as AI Warnings and Rising Oil Spook Traders
Major US stock indexes including the Dow, S&P 500, and Nasdaq fell sharply as technology traders reacted to artificial intelligence warnings from industry executives. The CEOs of Anthropic and OpenAI unsettled markets by calling for a slower pace of AI development due to potential technology risks. Meanwhile, oil prices jumped and the 10-year yield hit 5 percent as investors monitored upcoming Federal Reserve decisions. The tech selloff extended beyond pure AI slowdown fears, dragging down related equities during premarket trading.
Why it matters
The market pullback highlights growing anxiety over the rapid pace of artificial intelligence deployment and its broader economic implications. Tensions surrounding the technology escalated further after a Chinese state newspaper criticized Anthropic's calls to slow development as a Cold War tactic. Market participants are balancing these regulatory and geopolitical pressures alongside traditional macroeconomic concerns like interest rates and energy costs.

- The CEOs of Anthropic and OpenAI spooked markets while investors monitored rising oil prices and an upcoming Fed rate decision.
- U.S. stock index futures fell sharply on Monday with technology stocks under pressure after artificial intelligence executives called for a slower pace of development.
Still unconfirmed
