Wall Street records AI stocks once again dominated the market narrative on Tuesday, as the U.S. stock market edged to fresh all-time highs powered by the relentless momentum of the artificial-intelligence boom. Investors continued to pile into the companies seen as the biggest winners of the AI era, pushing major indices into uncharted territory.

A Record-Setting Session

All three major U.S. indices closed at all-time highs, capping a session marked by cautious optimism and AI-driven enthusiasm.

The day’s closing figures showed:

• The S&P 500 rose 0.1%, adding 9.82 points to 7,609.78
• The Dow Jones Industrial Average gained 228.91 points, or 0.4%, to 51,307.79
• The Nasdaq composite inched up 7.09 points, or less than 0.1%, to 27,093.90

While the gains were modest, the records underscored just how durable the market’s upward trend has become, even after an extraordinary run.

AI Winners Lead the Charge

The standout performers of the day were companies riding the AI wave, and several posted dramatic gains.

Hewlett Packard Enterprise helped lead the market, with its stock soaring 19.5% after reporting quarterly profits that blew past analyst expectations. The company credited surging demand from customers building out their artificial-intelligence capabilities.

Even more striking was Marvell Technology, which leaped 32.5% for its best single day since the stock began trading in 2000. The surge came after Nvidia’s CEO, Jensen Huang, suggested at a conference in Taiwan that Marvell could become “the next trillion-dollar company.”

The comment highlighted the expanding club of AI behemoths. The most recent entrant, Micron Technology, is likewise benefiting from the AI boom. Nvidia itself, whose total value has topped $5 trillion, slipped slightly by 0.7% on the day.

The Data Center Gold Rush

A key engine behind the rally is the massive spending on AI infrastructure, particularly enormous data centers.

Generac climbed 5.7% after announcing a deal to supply backup power generators to an unnamed leading hyperscale data center operator. These so-called “hyperscalers” are pouring tremendous sums into building vast AI data centers, which many proponents believe will power the next great revolution for the global economy.

Alphabet’s Massive Bet, and the Market’s Doubt

Alphabet, the parent company of Google, embodies both the promise and the peril of the AI spending frenzy. The company revealed plans to raise $80 billion in cash by selling shares to help fund its investments.

The scale of its ambitions is staggering. Alphabet plans to spend as much as $190 billion on equipment and other investments this year, a sum larger than the entire value of The Walt Disney Co. Even more notably, the company forecast that its investment spending next year would significantly increase.

Yet these enormous figures have raised pointed questions about whether AI can ultimately generate the profits and productivity needed to justify such spending. Critics have increasingly warned about the possibility of a bubble in AI investment.

That skepticism showed in Alphabet’s own stock, which fell 3.9% and became one of the heaviest weights dragging on the S&P 500.

Signs of a Possible Slowdown

Despite the record highs, some analysts caution that the broad market may be due for a breather. The Wall Street records AI stocks rally has been remarkably persistent, but it cannot run forever.

The S&P 500 has now logged nine straight winning weeks, its longest such streak since 2023. That momentum has been fueled largely by two forces:

• Strong profit reports from U.S. companies
• Hopes that the United States and Iran will reach a deal to reopen the Strait of Hormuz

A resolution on the strait would allow oil to flow freely again from the Persian Gulf, potentially easing prices.

Oil, Bonds, and Global Markets

Beyond equities, other markets reflected the broader uncertainty. In the oil market, prices rose again to recover more of last week’s slump. Brent crude, the international standard, climbed 1.1% to settle at $96.00 per barrel, still well above its roughly $70 level from before the war.

In the bond market, Treasury yields held relatively steady. The yield on the 10-year Treasury slipped to 4.45% from 4.47% late Monday. It briefly jumped after a report showed U.S. employers advertising far more jobs at the end of April than economists expected, a potential sign of continued labor market health, before quickly pulling back.

High yields worldwide remain a concern, threatening to slow economies and undercut prices for stocks and other investments. They have already pushed the average long-term U.S. mortgage rate to its most expensive level in nine months and could eventually curb the borrowing that funds AI data center construction.

Overseas, markets were broadly positive. Indices rose across much of Europe and Asia, with Hong Kong’s Hang Seng jumping 2.5% for one of the world’s biggest moves.

The Bigger Picture

The latest record highs capture a market driven by powerful but potentially fragile forces. The key themes now defining the rally include:

• AI enthusiasm propelling select stocks to extraordinary gains
• Massive infrastructure spending by hyperscalers like Alphabet
• Growing concerns about whether AI investment will pay off
• External risks from high bond yields and Middle East tensions

What Comes Next

As Wall Street records AI stocks continue to make headlines, the central question grows louder: can the artificial-intelligence boom deliver the returns needed to sustain its sky-high valuations?

For now, investor confidence remains strong, and the records keep falling. But with warnings of a possible slowdown, persistent worries about an AI bubble, and uncertainty over oil and interest rates, the market’s path forward is far from guaranteed. The coming weeks may reveal whether this historic rally has more room to run or whether the long winning streak is finally approaching its limits.
