The Form 4 filings show cofounder Henry Samueli selling about $250 million of stock a quarter, and today's buyers are paying less than his every exit price. [Broadcom](https://theinference.org/markets/companies/broadcom) CEO [Hock Tan](https://theinference.org/markets/people/hock-tan) called AI investors gamblers [at a Singapore conference on October 13](https://protos.com/broadcom-ceo-calls-ai-a-casino-after-co-founder-dumped-750-million/), saying they set "very extreme expectations only to find out that it's almost like they are in a casino" and have "no clue what they are investing in" [1]. The filings that same week show what his cofounder did with the stock those investors bought. [Henry Samueli](https://theinference.org/markets/people/henry-samueli), Broadcom's other founder and board chairman until June 2026, filed his third Form 4 of the year, taking total 2026 sales to about $750 million, roughly $250 million a quarter [1]. Tan himself sold 70,000 shares in January for over $24 million [1]. ## The cofounder's exits were priced near the top, and today's buyer pays less Samueli sold in March at a weighted average of $319.71 a share, in June at $382.13, and in September at $356.04 [1]. The June sale landed near the year's high. Broadcom shares sat [roughly a third below their 52-week high](https://finance.yahoo.com/technology/articles/broadcom-fought-t-over-vmware-020300795.html) last week [3], which puts the stock near $255, below every one of Samueli's three sale prices. The cofounder sold near the top; the retail crowd is buying lower than he sold, on a stock that has trailed the S&P 500 by 11 points this year [1]. ## The $21.7 billion guide is the number those sales sit under What makes the timing worth watching is the guidance. AI semiconductor revenue hit $16.7 billion last quarter, up 221%, now the majority of Broadcom's revenue, and management [guided $21.7 billion for the December quarter](https://slicast.com/article/16mb2xa), up 236% [2]. That is a forecast, not revenue earned, and it makes the next print unusually consequential [2]. A steadier software line, including a new 10-year VMware deal with Japan's NTT DOCOMO, softens but does not remove that exposure [3]. Samueli has every right to sell, and a diversified founder selling into strength is not evidence of anything sinister. But insiders banking about $250 million a quarter at $320 to $380 is a factual position taken ahead of a forecast the company itself calls pivotal. As we noted in September, Broadcom's AI promise rests on a handful of customers. Watch whether the December print reaches $21.7 billion, and whether the next Form 4 appears before it does. *Chart: **Samueli's three 2026 exits priced between $320 and $382 a share** Bars chart of the weighted average price per share of Henry Samueli's three 2026 Form 4 sales: March $319.71, June $382.13, September $356.04.* *Weighted average price per share in Henry Samueli's three 2026 Form 4 sales, from SEC filings reported by Protos, October 13, 2026.
