U.S. stocks climbed to fresh record highs on Tuesday, with falling oil prices, easing Treasury yields, and continued enthusiasm for artificial intelligence combining to lift markets across the board.

The S&P 500 rose to around 7,841 points, while the Nasdaq also set an all-time high. The Dow Jones Industrial Average gained more than 350 points during the session. Notably, all 11 S&P 500 sectors moved higher, signaling broad investor support across industries rather than a rally confined to technology. The easing in Treasury yields helped as well: lower yields shrink the discount rate applied to future corporate earnings, a dynamic that historically lends outsized support to growth-heavy technology shares.

Nvidia Nears $6 Trillion Valuation

Nvidia remains at the center of the rally. The chipmaker's shares gained roughly 1% on Tuesday, pushing its market value closer to the $6 trillion mark—a threshold no publicly listed company has ever crossed.

Nvidia has become a symbol of the AI spending boom, as technology companies continue to spend heavily on chips and data centers and demand for computing power stays elevated across the industry.

The broader tech sector also advanced on hopes for strong earnings. Analysts expect S&P 500 profits to rise more than 30% year over year in the third quarter, with AI-related demand one of the biggest drivers behind that growth. Investors are watching closely for confirmation in upcoming earnings reports, where the capital-spending plans of major cloud providers will offer a read on whether the AI buildout is still accelerating.

Uber to Buy ezCater for $2.3 Billion

Uber Technologies made separate headlines on Tuesday, agreeing to acquire U.S. corporate catering platform ezCater for $2.3 billion in cash. The deal strengthens Uber's position in workplace food delivery, a higher-ticket corner of the market where orders tend to be larger and more regular than everyday consumer deliveries.

ezCater generated more than $2.5 billion in gross bookings over the past year, and the average corporate catering order placed through the platform exceeds $400. Uber plans to combine ezCater with Uber Eats and Uber for Business as it attempts to close the gap with DoorDash in U.S. food delivery—a contest investors will be able to track in upcoming quarterly results.

Delivery accounted for roughly 37% of Uber's second-quarter revenue, and the ezCater deal gives the company another source of growth. That comes as investors also watch how self-driving vehicles could affect Uber's ride-hailing business over time.

Constellation Energy Jumps on Google Power Deal

Constellation Energy was one of Tuesday's biggest stock winners, with shares surging more than 13% after a new deal with Google.

Google agreed to buy 3,590 megawatts of electricity from Constellation in one of the largest power deals signed in the U.S. grid market. Around 890 megawatts will come from upgraded nuclear plants, with Constellation planning to invest more than $4.3 billion to expand capacity at reactors in Illinois, Pennsylvania, and New Jersey. A separate 15-year agreement covers another 2,700 megawatts of power. For Google, the pact secures long-duration electricity for its data-center footprint; for Constellation, it converts existing nuclear assets into contracted revenue backed by one of the world's largest technology buyers.

The transaction points to a growing theme in markets: AI is becoming a power story as well as a chip story. Large data centers need steady supplies of electricity, creating demand for utilities and nuclear plant operators. Energy infrastructure firms are benefiting alongside chipmakers, and attention now turns to whether other hyperscalers strike comparable long-dated power agreements as their data-center needs expand.

Falling Oil Helps Stocks Reach New Highs

Lower energy prices gave stocks another boost on Tuesday. Brent crude fell nearly % to around $98.48 per barrel, while U.S. West Texas Intermediate dropped to about $88 a barrel.

Oil prices have declined as Middle Eastern crude exports recover, and G7 countries are preparing an emergency release of diesel and crude reserves, adding further downward pressure on prices.

Lower oil prices matter for stocks because energy costs affect inflation. Falling crude can ease pressure on consumers and businesses, and it may also give the Federal Reserve more room to act on interest rates. Markets will watch future oil moves closely in the weeks ahead.
