US stocks rise to start the week as Anthropic's IPO filing revives AI appetite

what happened

US stock indices closed higher on Monday, according to Stocktwits, buoyed by Anthropic's public IPO filing and renewed optimism about artificial intelligence. The S&P 500 climbed 0.7% to 7,676.77, the Nasdaq 100 advanced 1.1%, the Dow Jones Industrial Average added 0.3% to 52,361.58, and the Russell 2000 gained 0.4%. Semiconductor funds rose about 3%, helped by AMD, Micron and Nvidia.

The filing showed more than 1,900 customers paid the Claude developer at least $1 million over the past year, nearly double the April figure. Per The Wall Street Journal, the listing is targeted for November, though timing may shift, and it could bring in over $100 billion at a valuation between $1.5 trillion and $2 trillion. Shares would trade under the ticker ANT on the Nasdaq Global Select Market.

Oil moved lower, with Brent futures down 0.8% to settle at $115.81 a barrel and WTI sliding 1.7% to $101.57. Investors now look ahead to quarterly reports from Microsoft, Amazon and Alphabet later this week, and to the Federal Reserve decision on Wednesday, where fed funds pricing points to a 90% chance rates stay in the 3.75% to 4% range.

why it matters

Rising AI enthusiasm and a large prospective listing are supporting tech sentiment, while oil above $100 a barrel keeps energy costs in focus. The Fed meeting and big-tech earnings are the next tests, and hyperscaler debt, highlighted by Meta's planned $95 billion raise, remains a risk to watch.
