AI‑Heavy Stocks Lift S&P 500 to Record

S&P 500 reaches new record highs driven mainly by AI‑focused Magnificent Seven stocks such as Nvidia, Microsoft and Broadcom.
Excluding AI heavyweights, the broader index would be in the red, with 118 S&P 500 stocks down over 10% since late February.
Only 82 stocks, largely AI‑linked, have risen more than 10%, sparking valuation froth and interest in upcoming AI IPOs like Anthropic and OpenAI.
Analysts debate a potential AI bubble, noting massive data‑center spending while near‑term free cash flow from AI developers remains limited.
