Stocks opened higher Wednesday thanks to a tame inflation report. A reinvigorated AI trade, courtesy of several well-received earnings reports, kept equities mostly higher into the close, with one of the three main indexes nearing a new record high.
The broader S&P 500 finished up 0.3% at 7,748 — just shy of last Friday’s all-time closing high of 7,757.67 — and the tech-heavy Nasdaq Composite added 0.5% to 26,588. The blue-chip Dow Jones Industrial Average turned lower in the final minutes of the session, finishing down 0.04% at 53,770.
Things got off to a solid start this morning after the Bureau of Labor Statistics (BLS) said the Consumer Price Index (CPI) rose 0.1% from June to July and was up 3.4% year over year.

This matched economists’ expectations, while the 12-month rate rose at a slower pace than June’s 3.5% increase.
Cooling energy prices had a positive impact on headline inflation, but even core CPI, which excludes volatile food and energy costs, was mild. Core inflation rose 0.2% month over month and was 2.5% higher year over year. This compares to June’s flat monthly reading 2.6% annual increase.

“For the Federal Reserve, this is a helpful report rather than an all-clear,” says Daniela Hathorn, senior market analyst at Capital.com. “Inflation is moving in the right direction despite the earlier energy shock, while recent weakness in the labor market gives policymakers even less reason to consider another rate increase in September.”
But inflation remains above the Fed’s 2% target, Hathorn adds, meaning the central bank “is unlikely to declare victory yet, especially after Kevin Warsh was adamant to point out his focus on making sure that high inflation does not become detrimental to the U.S. economy.”
Still, the July CPI report lowered expectations that the Fed will hike rates next month. According to CME Group FedWatch, futures traders are now pricing in a 60% chance the central bank will keep the federal funds rate unchanged next month — up from 52% one day ago.
Super Micro, CoreWeave stocks soar on earnings
Well-received earnings reports from several artificial intelligence companies also lifted sentiment on Wednesday.
Super Micro Computer (SMCI), for one, was the best S&P 500 stock today, surging 19% after the AI server, software and infrastructure company disclosed higher-than-expected fiscal fourth-quarter earnings and gave strong fiscal 2027 first-quarter guidance.
“We added several hundred enterprise and other customers in the past year, generated more than $60 billion in new orders, and booked record backlog entering fiscal 2027,” said Super Micro Computer CEO Charles Liang in the press release.
CoreWeave (CRWV), meanwhile, jumped 19.3% after the AI cloud platform said second-quarter revenue more than doubled year over year — and that it expects more of the same in Q3.
“We believe CRWV is positioned to capture meaningful share of an AI cloud provider market growing at a server-melting pace, and we continue to see growing demand for CRWV’s platform,” says Mizuho Americas analyst Gregg Moskowitz.
However, the analyst cautions that the AI stock‘s risk/reward is “somewhat balanced given some ongoing uncertainty about the magnitude of CRWV’s revenue upside over the near term.”
Nebius pops 34% after earnings
While Wednesday’s gains for Super Micro and CoreWeave stocks are certainly impressive, Nebius Group (NBIS) emerged as the day’s hottest stock — popping 34.1% after the AI cloud infrastructure company said revenue surged more than fivefold in its second quarter, to $582.3 million.
Nebius’ results show that “AI compute demand is insatiable and pricing is strengthening, not weakening,” says Luke Lango, lead technology and cryptocurrency analyst at InvestorPlace.
Short sellers may have helped Nebius’ red-hot rally, too. Nearly 25% of NBIS’ stock is sold short, meaning speculators bet that its share price would drop. When a stock starts to soar, short sellers are forced to buy back the shares they sold short in order to contain their losses — and we may have seen some of that in today’s price action.
