Key Points

• Nvidia’s market capitalization crosses $5 trillion, making it the first company to hit the milestone.
• Microsoft slips ahead of the release of its quarterly earnings. It closed Tuesday with a market value exceeding $4 trillion.
• Alphabet and Meta Platforms are scheduled to report earnings after the closing bell Wednesday.

The S&P 500 closed flat Wednesday after Federal Reserve officials lowered interest rates by a quarter-point, as expected, and voted to stop shrinking the Fed’s balance sheet through a strategy known as quantitative tightening.

These stocks made notable moves Wednesday:

Nvidia rose 3.1% and surpassed a valuation of $5 trillion, making it the first company to hit the milestone. It has been just 78 trading days since Nvidia hit $4 trillion. The gains came after CEO Jensen Huang said Nvidia now has visibility on more than $500 billion of cumulative revenue for its current Blackwell AI chips and future Rubin chips through 2026. President Donald Trump remarked he may discuss the Blackwell chips with Chinese President Xi Jinping when the two leaders meet Thursday.

Micron Technology gained 2.1% after its larger rival in the memory chip space, South Korea’s SK Hynix, forecast a “supercycle” of demand powered by the boom in artificial-intelligence investments.

Microsoft fell 0.1%. Shares rose 2% on Tuesday to a record $542.07, causing Microsoft to finish the session with a market capitalization of $4.03 trillion for the first time. It’s scheduled to report fiscal first-quarter earnings after the closing bell.

Joining Microsoft Wednesday on the earnings docket are Google parent Alphabet , which rose 2.6% ahead of its third-quarter earnings report scheduled after the market closes Wednesday, and Meta Platforms , the owner of Facebook and Instagram, which was flat ahead of the release of its quarterly numbers.

Earnings reports are also expected after the closing bell Wednesday from ServiceNow, KLA Corp., Carvana, Starbucks, Chipotle Mexican Grill, and eBay.

Centene surged 13% after the health insurer posted third-quarter adjusted earnings of 50 cents a share, better than expectations for a loss of 14 cents. Revenue of $49.69 billion beat Wall Street estimates of $47.72 billion.

CVS Health declined 2%. The health insurer posted third-quarter adjusted earnings and total revenue that topped analysts’ expectations. However, CVS Health swung to a net loss as it posted a $5.7 billion goodwill impairment charge tied to its senior clinics business, which it bought in 2023.

Caterpillar jumped 12% after the maker of heavy construction equipment reported better-than-expected-third quarter earnings and revenue.

Verizon Communications gained 2.3%. The wireless carrier beat third-quarter earnings estimates, missed on revenue, and promised to make big changes to its business under new CEO Dan Schulman.

Seagate Technology climbed 19% after the data storage company topped Wall Street earnings estimates in its fiscal first quarter and forecast its profit and revenue for the current second quarter also would top expectations.

Shares of Caesars Entertainment tumbled 15% after the casino operator reported disappointing quarterly earnings, driven in part by weak results in Las Vegas. Revenue in the city, which accounts for about one-third of Caesars’ business, dropped 9.8% from a year earlier.

Fiserv sank 44% after the financial-technology company said it expects full-year adjusted earnings of $8.50 to $8.60 a share, down from its previous outlook of $10.15 to $10.30. BTIG analysts noted that sentiment was “already very weak” ahead of the report, and the guidance cut “will only maker investor appetite more challenged.” Fiserv also named co-presidents and a new finance chief.

Bloom Energy soared 18% after posting third-quarter adjusted profit of 15 cents a share, beating analysts’ expectations of 10 cents. Revenue of $519 million outpaced expectations for $428 million. Bloom Energy shares have risen more than 400% in 2025, largely on expectations that it will play a role in providing power for AI data centers.

Enphase Energy fell 15% after the maker of solar-power inverters said its third-quarter profit and revenue rose from a year ago, but issued fourth-quarter revenue guidance that missed analysts’ expectations.

Teradyne shares jumped 21% after the automatic test equipment designer said it expects a 27% jump in sales in the fourth quarter as “AI-related test demand remains robust across compute, networking and memory segments.”

Stride plunged 54% after the online education company’s revenue guidance for its fiscal second quarter and fiscal year missed analysts’ forecasts. Company executives said on a call with analysts that investments in third-party platforms to upgrade its online learning platform didn’t go as smoothly as expected. That and other factors led to about 10,000 to 15,000 fewer enrollments.
