Nvidia, Palantir and Tesla send shockwaves through Wall Street with this $53 billion warning

For the better part of the last four years, no catalyst has played a more significant role in the rise of the broader market than the evolution of artificial intelligence (AI). Whether it’s hardware or AI acceleration applications, an IDC report puts this cumulative opportunity at $22.5 trillion from 2025 to 2031.

Few companies have taken the bull by the horns as much as AI. Nvidia (NVDA +2.77%), Palantir Technologies (PLTR +3.48%)And Tesla (TSLA +4.23%).

Nvidia’s graphics processing units (GPUs) form the backbone of AI-accelerated data center infrastructure. None of its competitors come particularly close to matching the computing capabilities of its multiple generations of GPUs.

Meanwhile, AI-based software-as-a-service provider Palantir is a true model for deploying AI applications. The company’s Gotham platform helps the U.S. military plan and monitor its missions.

Electric vehicle manufacturer Tesla is also a specialist in AI applications. AI is integral to the success of its fully autonomous driving software and Optimus humanoid robots.

Even though this trio has thrived amid AI infrastructure development, the individuals who know these companies best are sending the wrong signals to Wall Street.

Nvidia, Palantir and Tesla insiders shake Wall Street to its core

Although stock analysts spend day after day studying the same industry and the companies that define it, no one understands Nvidia, Palantir, and Tesla better than their respective insiders.

An “insider” is a high-ranking executive, board member or beneficial owner of at least 10% of the outstanding shares of a company who may have non-public information. Whenever an insider buys or sells shares in their company, they are legally required to file Form 4 with regulators within two business days. This lets investors know whether a company’s insiders have been buying or selling.

In the case of this AI power trio, insiders have been undeniable net sellers of their company’s stock over the past five years:

• Nvidia: $6,860,636,476 in net sales
• Palantir: $6,371,606,538 in net sales
• Tesla: $39,479,555,646 in net sales

Collectively, insiders at these companies have sold more than $52.7 billion worth of their own company stock compared to what they have purchased since early November 2021.

There is, however, an asterisk that must accompany the above data. Because high-ranking executives and board members are often compensated in stock or options, they are required to sell some of their ownership interests to cover their federal and/or state tax obligations. In other words, insider selling isn’t automatically a bad thing, especially if it’s for tax purposes.

What’s equally troubling, from an investing perspective, is the relative lack of insider buying. With the exception of a large purchase totaling nearly $1 billion by Tesla CEO Elon Musk, insider buying has been virtually non-existent in this trio over the past five years:

• Nvidia: $250,000 in insider purchases
• Palantir: $7,837,856 in insider purchases
• Tesla: $1,000,984,274 in insider purchases

If insiders aren’t buying, historical precedent might explain why.

For over 30 years, every revolutionary innovation has gone through an event that erupted at the start of the round. This includes the Internet, 3D printing, blockchain technology and the metaverse.

Stock market bubbles throughout history… AI stocks now make up about 40% of the market. https://t.co/RxSAh09k6F

The reason these bubbles form and then burst is because investors systematically overestimate the pace of optimization of breakthrough technologies. Although AI solutions have been welcomed with open arms, it will likely be several years before companies optimize these solutions to increase sales and profits. In other words, the door is wide open for a possible AI bubble bursting event.
