Stock market today: Dow, S&P 500, Nasdaq fall as Anthropic's AI warning spooks tech traders, oil prices jump

Primary Journalistic Dispatch & Direct Reporting

The tech-heavy Nasdaq-100 ( ^IXIC ) fell 0.8%, led by losses in chip stocks, including Nvidia ( NVDA ). The Dow Jones Industrial Average ( ^DJI ) fell 0.3%, while those on the S&P 500 ( ^GSPC ) declined by 0.6%. In Asia, shares of memory chip makers SK Hynix ( SKHY ) and Samsung ( 005930.KS ) dropped.

Tech stocks were poised to fall after Anthropic ( ANTH.PVT ) CEO Dario Amodei wrote a 3,800-word essay over the weekend, arguing that AI companies should slow the pace of improving AI models in order to address safety concerns . Sam Altman, the CEO of rival AI lab OpenAI ( OPAI.PVT ), agreed in a post on X, putting the two AI companies at odds with Wall Street, which has banked on a brisk pace of improvement.

Worries about AI safety also led OpenAI to delay its initial public offering until 2027, Altman told Fortune. Anthropic still plans to list in the fall and has reportedly chosen the Nasdaq for its highly anticipated IPO.

In-Depth Developments & Factual Context

Oil prices, meanwhile, continued to climb after Saudi Arabia shut down a key pipeline in the Middle East and as the war in the Middle East spread. Brent crude ( BZ=F ) traded near $108 per barrel.

That sets the stage for the Federal Reserve's policy meeting on Wednesday. Trader bets of a Fed rate hike have spiked to 88% following Friday's consumer inflation report , creating a consensus even as Fed Chairman Kevin Warsh has emphasized that he will not provide forward guidance about the Fed policymaking.

Stocks opened lower on Monday as investors pulled back on risk.

Industry Impact & Strategic Analysis

The tech-heavy Nasdaq Composite ( ^IXIC ) fell by 1.2%, led by some of the AI trade's most high-flying chip stocks . Investors are grappling with whether the massive AI buildout could slow after AI leaders this weekend called for a temporary curb on frontier model development due to safety concerns .

The S&P 500 ( ^GSPC ) fell by 0.7% while the Dow Jones Industrial Average ( ^DJI ) fell by 0.2%.

Forward Outlook & Market Perspective

A bumpy start to the week for stocks isn't all that new. As of Monday's open, the three major indexes have either begun trading week mixed or down for six weeks straight.

Energy price pressure is letting up either as Middle East supply disruption spread to a crucial Saudi pipeline over the weekend. Brent crude ( BZ=F ) is hovering around $109 per barrel, up over 4% for the last 24 hours.

Meanwhile, the 10-year Treasury yield ( ^TNX ) is just below 5% , a level it hasn't crossed since 2023.

Traders put odds of the Fed announcing a hike later this week at 88.5%, according to the CME FedWatch tool, but the central bank's decision is likely closer than those odds suggest .

The 10-year Treasury yield ( ^TNX ) climbed to 4.97% on Monday, just 3 basis points away from the 5% threshold. Meanwhile, the 30-year Treasury ( ^TYX ) yield hovered at 5.35%.

Bond yields stayed elevated as Brent crude climbed to $107 a barrel, stoking inflation fears and leading investors to price in rate hikes ahead of the Federal Reserve's policy meeting this week.
