Wall Street’s main indexes rose on Tuesday as Palantir’s results aided optimism around the AI trade, while investors geared up for a flood of corporate results through the week.

Palantir Technologies jumped 8.6% after upbeat results highlighted demand for its military-grade AI tools, with U.S. defense spending helping lift quarterly sales.

Teradyne rose 7.8% after the chip-testing equipment maker issued a strong first-quarter forecast, riding a separate wave of AI-linked investment as big tech pours multibillion-dollar sums into data-center expansion.

“(Palantir) earnings definitely have helped revive the AI trade this morning,” said John Campbell, senior portfolio manager, Allspring Global Investments.

Alphabet rose 0.8% after notching a record high in the previous session, while Amazon added 0.6%. Both the “Magnificent Seven” heavyweights are due to report later this week, offering investors another read on the race to commercialize artificial intelligence.

Advanced Micro Devices and server maker Super Micro Computer, both due to report after the market close, were higher. The Philadelphia SE Semiconductor Index rose 0.7%.

“We’ve got kind of an expensive market and expectations are really high. So there are many areas of the market, especially around AI, that are somewhat priced for perfection. That’s just got us in a little bit of a skittish environment,” Campbell added.

Earnings from the biggest technology companies have underscored a growing investor focus on payback from soaring capital expenditure plans. Spending on AI-related infrastructure has climbed sharply, putting pressure on companies to translate investment into measurable returns that can support lofty valuations.

Meanwhile, Walt Disney on Tuesday named theme parks head Josh D’Amaro as CEO, placing a longtime insider at the helm and ending succession uncertainty. The company’s shares dipped 1.2%.

Earnings Deluge

PayPal forecast 2026 profit below estimates, sending its shares falling 17.3%.

Pfizer shares fell 4.4% despite posting fourth-quarter profit above estimates, while Merck’s shares rose 3% after quarterly results.

PepsiCo shares gained 1.7%, with the brand announcing a price cut on core brands such as Lay’s and Doritos.

Chipotle Mexican Grill, Cadbury maker Mondelez and household products maker Clorox are scheduled to report after the bell.

On the macro front, the House of Representatives will try to pass a deal later in the day to end the latest shutdown that has again thrown economic releases off schedule, delaying the closely watched January jobs report that had been due on Friday.

Tuesday’s JOLTS report has also been postponed.
