Insiders Cash Out at NVDA, WMT, AMAT

A wave of high-value insider selling hit several major US names this month, with filings revealing over $1.6 billion in combined exits across NVDA, WMT, AMAT, and ASTS.

NVIDIA director sells $410M. Mark Stevens, an independent director at NVIDIA, filed sales totalling $410M across multiple tranches. Trades were reported between June 4 and June 23. Stevens sold shares at prices near NVIDIA's recent highs.

Walton family trims Walmart. The Walton Family Holdings Trust filed $793M in Walmart sales over four separate dates. The largest single tranche — $467M — was reported on June 18. The trust remains one of the company's dominant shareholders.

AMAT C-suite moves in sync. Seven Applied Materials insiders filed sales on June 17. CEO Gary Dickerson alone accounted for over $45M across multiple transactions. The CTO and a division president also sold. This kind of coordinated C-suite selling is worth watching.

AST SpaceMobile founder sells $147M. Abel Avellan, founder and CEO of AST SpaceMobile, filed a $146.7M sale on June 23. He sold 2.5 million shares. That is a significant exit from a company whose stock has rallied sharply in 2026.
