Nvidia, Palantir, Alphabet insiders dump $17.5 billion

The article frames the insider activity against the backdrop of the AI infrastructure build-out, which it compares to the internet's arrival three decades ago. Nvidia's graphics processing units hold a virtual monopoly in AI-accelerated data centers, Palantir's Gotham platform is described as critical for overseeing military operations for the U.S. and its allies, and Alphabet's Google Cloud sales growth has gone parabolic since integrating generative AI and large language model capabilities. Yet the people who know these companies best have been net sellers — to the tune of roughly $17.5 billion since October 2021.

The article notes an important caveat: insiders often sell to cover taxes on stock-based compensation, which shouldn't alarm everyday investors. The more telling signal, it argues, is the lack of buying. Insider purchases have been underwhelming over the trailing five years, and since the only reason to buy is the expectation of share-price appreciation, the absence of purchases raises questions. Valuation may be one answer, with Palantir trading at a price-to-sales ratio of almost 80, well above the 30 level the article says history has shown to be sustainable.

Beyond valuation, the article points to a historical pattern: every game-changing innovation endures an early-innings bubble-bursting event, because investors constantly overestimate the pace of optimization of new technologies. While AI adoption hasn't been an issue, it'll likely take years for businesses to optimize AI solutions to maximize sales and profits. That, the article suggests, leaves the door wide open for an AI bubble-bursting event — though the timing and severity remain uncertain.
