Nvidia, Palantir, and Meta Platforms Are Rattling Wall Street With This $18.6 Billion Warning

No trend has fueled Wall Street's nearly four-year bull market quite like the evolution of artificial intelligence (AI). Empowering software and systems with the tools to make autonomous, split-second decisions is a multitrillion-dollar addressable opportunity that investors clearly don't want to miss.

Several of Wall Street's most influential businesses have led the AI revolution, including Nvidia (NASDAQ:NVDA), Palantir Technologies (NASDAQ:PLTR), and Meta Platforms (NASDAQ:META).

Nvidia is the heart and soul of the AI infrastructure build-out. Its graphics processing units (GPUs) hold a virtual monopoly in AI-accelerated data centers, with no other GPU makers particularly close to rivaling the compute capabilities of its hardware.

Meanwhile, Palantir and Meta have demonstrated the value of AI applications. Palantir's AI-driven software-as-a-service platform, Gotham, helps the U.S. government and its allies plan and oversee military operations, while Meta has deployed generative AI solutions across its social media advertising platforms that allow businesses to tailor static and video ads to individual users.

Although all three AI titans are growing their sales and profits at a breakneck pace, things may not be as perfect as their headline operating results suggest.

The people who know Nvidia, Palantir, and Meta best are sending a terrifying message to Wall Street

Arguably, no one knows these three leading businesses better than their insiders, consisting of high-ranking executives, board members, and beneficial owners of at least 10% of outstanding shares.

Securities law requires insiders to file Form 4 with regulators no later than two business days after buying or selling shares of their company's stock, including the exercising of option contracts. Aside from complying with securities law, this transparent reporting allows investors to effectively track whether insiders are putting their money where their mouth is.

Based on Form 4 filings over the trailing five-year period (as of Sept. 4), insiders at this AI trio have been notable net sellers of their company's stock:

• Nvidia: $6.31 billion in net insider sales
• Palantir: $6.63 billion in net insider sales
• Meta: $5.69 billion in net insider sales

Collectively, the people who know these companies best have dumped approximately $18.6 billion more in stock than they've purchased over the last half-decade.

However, it's important to keep in mind that high-ranking executives and board members are often heavily compensation in stock and/or options. Selling shares to cover federal and/or state tax bills is often required. In other words, tax-based selling isn't necessarily bad news for investors.

Unfortunately, insiders are raising red flags at both ends of the spectrum. While there are several reasons for insiders to sell shares, not all of which are nefarious, there's only one reason to buy: the belief that shares will rise. Over the trailing five years, insider buying has been almost nonexistent:

• Nvidia: $250,000 in insider buying
• Palantir: $7,837,856
• Meta: $0

This lack of insider buying may speak to the checkered history of next-big-thing technological innovations. While insiders at all three companies are undoubtedly excited about AI altering their respective futures, every game-changing innovation since the mid-1990s has endured an early stage bubble-bursting event. Investors have consistently overestimated the pace of adoption or optimization of new technologies, leading to eventual disappointment.

Nothing suggests that artificial intelligence is the exception to this unwritten rule.
