S&P 500 rises 0.76% and Nasdaq 100 gains 1.48% at the open on CoreWeave results

U.S. stocks opened higher on Wednesday, November 11, 2026, with the S&P 500 at 7577.79, up 0.76% at 09:45 a.m. in New York. The Nasdaq 100 gained 1.48% to 28152.53 as CoreWeave's results eased worries about AI spending.

What happened

The S&P 500 stood at 7577.79 at 09:45 a.m., against a previous close of 7520.93. That is a gain of 56.86 points, or 0.76%. The Nasdaq 100 traded at 28152.53, up 411.74 points from a previous close of 27740.79.

The CBOE Volatility Index stands at 18.67, down 0.79 points, or -4.06%, from a previous close of 19.46. A lower reading points to somewhat calmer conditions in options pricing than a day earlier. Futures for both indexes had already shown gains before the bell, and Nasdaq futures were up nearly 2% in early trading.

Technology led the move, as the larger gain in the Nasdaq 100 shows. Nvidia shares rebounded after a significant drop earlier.

Why it matters

CoreWeave's earnings were the main catalyst. The company predicts profitability by the first half of 2028. That outlook eased fears about the scale of AI spending, a theme that has worried investors in technology shares.

Nvidia's recovery adds to the picture. The company is a central name in AI hardware, so its shares carry weight for sentiment across the broader market. A stronger Nvidia often lifts the wider group of chip and data-center names.

Rates remain a counterweight to the optimism. Market commentary says the latest inflation data has raised the odds of Fed interest rate hikes. Higher rates tend to weigh on the valuations of growth companies, which are heavily represented in the Nasdaq 100. For investors, the open shows that AI earnings and the Fed outlook are the main forces behind price action at present.

What to watch next

The first question is whether the early gains hold through the session at the New York Stock Exchange, which runs until 4:00 p.m. The VIX will show if the calmer tone persists after its early decline from 19.46.

Attention also stays on further AI-related earnings and on any new signals about Fed policy. Both can shift the balance between the growth story that lifted technology shares today and the rate concerns that follow the latest inflation data.
