Nvidia CEO Jensen Huang's surprise resignation triggered a scramble out of Nvidia-linked stocks and into Taiwan's custom chip (ASIC) makers, a clear win for that group and a warning sign for Nvidia's direct supply chain.

• MediaTek, Alchip, and GUC (Taiwan's top ASIC design firms) all hit daily price limits as traders bet big cloud companies will lean harder on their own custom chips instead of Nvidia GPUs.
• Big US cloud firms are already diversifying away from Nvidia toward AMD and Broadcom, and firms that do pure chip design work are seen as the biggest winners from this shift.
• Nvidia's own stock fell on the news and lost around $180 billion in value in a day, while Super Micro dropped even harder on the leadership shakeup plus a reported Justice Department probe; US retail investors rushed in to buy the dip, limiting Nvidia's losses.
• Taiwanese supplier Pegatron wobbled on the news but analysts still expect strong AI server demand ahead and kept a buy rating.
• Taiwan's broader stock market actually jumped over 1,200 points despite the Nvidia shock, as money rotated into the ASIC winners.

Outlook: Expect continued volatility in Nvidia-linked suppliers short-term, while ASIC-focused chipmakers keep attracting investor money as cloud giants push further into custom silicon.
