AI Stock Selloff Weighs on S&P 500 as Investors Shift Focus to SpaceX IPO Buzz

TLDR:

• Mega-cap AI stocks declined sharply, placing pressure on the S&P 500 despite broader market resilience.
• Oracle posted an 11.54% drop, making it the weakest major technology stock on the heatmap.
• Nasdaq remained above 1% while the S&P 500 stayed barely positive during the trading session.
• Market participants discussed a possible shift from crowded AI trades toward SpaceX IPO-related interest.

Large-cap technology stocks faced broad selling pressure, weighing on major U.S. equity benchmarks despite continued strength in parts of the Nasdaq.

Market participants appeared to reduce exposure to several leading artificial intelligence-related companies as attention turned toward the highly anticipated SpaceX IPO.

Mega-Cap Technology Stocks Lead Market Decline

A market heatmap shared by Bull Theory showed widespread losses across major technology companies. The largest declines came from several firms closely associated with the artificial intelligence trade, which has driven much of the market’s gains in recent years.

In a post on X, Bull Theory stated that AI stocks were being sold ahead of the expected SpaceX IPO. The post noted that Google, Microsoft, Meta, and Oracle were among the biggest contributors to the S&P 500’s weakness during the session.

According to the heatmap, Microsoft fell 2.57%, while Alphabet declined 2.52%. Meta dropped 2.24%, and Amazon traded 1.03% lower. The losses were notable because of the companies’ large weightings within major indexes.

Oracle recorded the steepest decline among the major names displayed on the chart. Shares fell 11.54%, making it the largest negative performer visible on the heatmap. The move stood out against a broader backdrop of technology-sector weakness.

Other companies also traded lower during the session. Netflix declined 2.04%, while Palantir fell 1.46%. Cisco lost 0.93%, and IBM slipped 0.80%. The selling extended beyond technology, with financial companies also posting losses.

Visa declined 1.09%, Mastercard fell 0.76%, American Express lost 0.98%, and Wells Fargo dropped 1.09%. The broad participation in the selloff suggested weakness was not limited to a single industry group.

Rotation Narrative Gains Attention as Nasdaq Holds Up

Bull Theory argued that more than $200 billion in market value had been erased from Google, Microsoft, Meta, and Oracle combined during the session.

The account also noted that the Nasdaq remained more than 1% higher while the S&P 500 was only marginally positive.

That divergence drew attention because mega-cap technology stocks often play a major role in index performance. When some of the market’s largest companies decline, they can place pressure on broader benchmarks even if other sectors remain stable.

The heatmap showed concentrated selling among many of the most widely held AI-related stocks. Microsoft, Google, Meta, Oracle, and Palantir all traded lower, reflecting reduced demand for names that have attracted strong investor interest over the past year.

At the same time, the chart alone did not provide direct evidence that capital was moving into the SpaceX IPO. It showed where selling occurred but did not identify where those funds were ultimately allocated.

Still, the timing fueled discussion about portfolio repositioning ahead of what many investors view as one of the most anticipated public offerings in recent years. Market participants often adjust holdings before major listings, particularly when investor interest is elevated.

For now, the heatmap points to a session dominated by weakness in large-cap technology stocks. Those declines were enough to pressure the S&P 500, while strength elsewhere helped keep the Nasdaq in positive territory.
