Update: Equities Fall Intraday Amid AI Safety Warnings

01:56 PM EDT, 09/14/2026 (MT Newswires) -- (Updates with latest market prices and developments.) US benchmark equity indexes were lower intraday as Anthropic and OpenAI flagged increasing safety risks tied to artificial intelligence. The S&P 500 was down 0.3% at 7,635.4 after midday Monday. The Nasdaq Composite and the Dow Jones Industrial Average fell 0.2% each to 26,291.4 and 52,493.7, respectively. All three main indexes finished Friday trading higher, snapping a four-day losing streak. Among sectors, industrials led the laggards intraday Monday, while communication services paced the gainers. Dario Amodei, chief executive of AI chatbot Claude maker Anthropic, called on the industry Saturday to slow the pace at which it advances AI model capabilities. OpenAI CEO Sam Altman and Tesla (TSLA) and SpaceX (SPCX) CEO Elon Musk supported Amodei's call. OpenAI's initial public offering will not take place this year, Altman separately said in a Fortune Magazine interview, citing the need for safety-related work, according to Bloomberg News. Shares of technology bellwether Nvidia (NVDA) were the third-worst performer on the Dow, down 2.7%. Advanced Micro Devices (AMD), Micron Technology (MU), SanDisk (SNDK), Intel (INTC) and Qualcomm (QCOM) were also down intraday. West Texas Intermediate crude oil was up 1.8% at $101.84 a barrel intraday, while Brent rose 1.5% to $106.11, both trading off the day's peaks. The Islamic Revolutionary Guard Corps said it destroyed an advanced US MQ-1 drone over the Strait of Hormuz, a key crude and energy chokepoint, CNBC reported. A meeting to discuss the future of the strait, scheduled for Monday with Tehran and Gulf states, has been postponed, Omani Foreign Minister Badr Albusaidi said on X. The postponement comes following Yemen's Iran-aligned Houthis' attack on Saudi Arabia last week. US President Donald Trump said Monday that Iran "wants to make a deal, quickly and badly." "I will determine whether or not the USA will choose to engage," Trump said in a social media post. Treasury yields were lower, with the two-year rate retreating 2.6 basis points to 4.62% and the 10-year rate falling two basis points to 4.96%. The Federal Reserve is expected to raise interest rates by 25 basis points at this week's policy meeting, with its latest "dot plot" likely signaling another hike later this year, UBS Securities said in a note. The Federal Open Market Committee kicks off its two-day meeting on Tuesday. Markets are currently pricing in a 93% probability that the Fed will raise the benchmark lending rate by 25 basis points on Wednesday, according to the CME FedWatch tool. The remaining odds point to another central bank pause. In other company news, Baldwin Insurance (BWIN) has agreed to be acquired and taken private by a consortium that includes the family investment firm of Dell Technologies (DELL) Chief Executive Michael Dell, in a deal worth $7.7 billion. Baldwin shares were up 7.7% intraday. Spot gold lost 1% to $4,306.30 per troy ounce, while silver shed 2% to $63.92 per ounce.
