AI company insiders sold $7.4 billion into the top, before this week's rout

Executives and directors at nine publicly traded US AI firms sold a combined $7.39 billion of their own stock between May and October — months before the sector reversed hard this week, according to a tally by Protos drawn from SEC Form 4 filings.

The selling spanned 282 Form 4s across Nvidia, Oracle, Micron, Broadcom, AMD, SanDisk, CoreWeave, Arista and Astera Labs, Protos reported. Stripping out $179 million in tax-related sales, discretionary exits still came to more than $7.2 billion across 243 filings.

The context is a sharp downturn. The PHLX Semiconductor Sector index is down 32% from its October high and 16% so far in November, per Protos. On Thursday, US-listed stocks shed $3.2 trillion in market capitalization in a single session and the Nasdaq 100 fell 6.4%; South Korea's KOSPI dropped 8.5%, triggering a limit-down circuit breaker.

The largest individual sales, as logged by Protos: Nvidia director Mark Stevens sold roughly $1.3 billion across five filings this year at $210–$235 a share (Nvidia closed the prior session at $181.60). Broadcom co-founder Henry Samueli sold $750 million. CoreWeave insiders sold $2.88 billion across 141 filings — $740 million of it after the company's Nasdaq 100 inclusion. AMD CEO Lisa Su sold 360,000 shares for $169 million; SanDisk CEO David Goeckeler took $105 million at $1,523–$1,587 a share in September, versus an $806.43 close before Thursday.

Key facts

• $7.39B sold across 282 Form 4s, May–October, at nine AI firms; $7.2B+ discretionary (ex-tax) across 243 filings — Protos, from SEC Form 4 filings
• $3.2T in US market cap wiped out Thursday; Nasdaq 100 –6.4%; KOSPI –8.5% (circuit breaker) — Protos
• PHLX Semiconductor index: –32% from October high, –16% in November — Protos
• Nvidia's Mark Stevens: ~$1.3B across five filings at $210–235/share; NVDA last close $181.60 — Protos, citing Form 4s
• CoreWeave insiders: $2.88B across 141 filings; stock closed Thursday 68% below its 2026 high — Protos

The real-world read

The numbers are real and traceable to Form 4s, but the framing deserves a cold eye. Protos's "right on time" headline implies foresight — that insiders knew the top. The filings don't show that. Form 4s generally don't distinguish opportunistic sales from pre-scheduled 10b5-1 plans (the data here separates only tax-related sales), and executives selling into a multi-year rally is routine, not prophetic. The $7.39 billion is a cumulative sum across nine companies over six months, not a coordinated pre-crash dump.

This is also a single-outlet tally. Protos is a reputable secondary source, but the aggregate figure is its own compilation; the underlying primary records are the SEC filings it cites. Correlation — sold high, then stocks fell — is documented. Causation or inside knowledge is not.

This is news reporting, not investment advice.
