The last 10 days proved an exceptionally busy period for the biggest Nvidia (NASDAQ: NVDA) stock insider trader, as he, across two sales, dumped nearly $650 million worth of the semiconductor giant’s equity.
Indeed, on September 8, a Securities and Exchange Commission (SEC) filing revealed that Director Mark Stevens sold slightly more than 1 million NVDA shares at an average price of $230.51.

Notably, Stevens executed the biggest Nvidia stock insider sale of the decade just days earlier when he dumped nearly $411 million worth of NVDA. Lastly, the prolific trader is responsible for 81.91% – $1.09 billion – of the $1.33 billion total raised in 2026 by the blue-chip chipmaker’s executives and other senior personnel.
Big tech stocks see elevated insider trading since August
Meanwhile, the Nvidia stock insider selling is notable primarily because it is part of a wider trend in big tech.
Specifically, as recent weeks saw significant recovery from the sector-wide downturn that started in June following temporary highs, they also ushered in a period of extensive equity dumping.

Along with Nvidia, Microsoft (NASDAQ: MSFT), Amazon (NASDAQ: AMZN), Palantir (NASDAQ: PLTR), and SanDisk (NASDAQ: SNDK) all saw major sales since early August, with AMZN and MSFT arguably being the most significant due to scale.
Why are big tech insiders selling stocks en masse?
Overall, the insider activity is worth keeping in mind due to its generally heightened level amidst a market rebound, but also due to the continuous instability of the pivotal artificial intelligence (AI) boom.
Recent months have brought a relentless marketing campaign about the capabilities of new models and apparent breakthroughs across various fields, but also little in terms of measurable financial benefits and corporate experiments that ended in what appears, at best, akin to felony hacking.
Furthermore, the narratives have also been somewhat confusing, with Jensen Huang of Nvidia declaring that artificial general intelligence (AGI) has been achieved despite the significant divergence in the current definitions of AGI and, indeed, no known model fitting the general notion of AGI.
Lastly, the latest flood of insider selling comes ahead of a significant political risk for the AI ‘boom.’

Opposition to data center construction – one of the most profitable parts of the overall industry, even if for a small handful of companies – in the U.S. has been mounting ahead of the Midterms, meaning the results of the fight for Congress could significantly impact valuations.
