This stake consists of PUT bets worth close to 3 million shares. Previously, Leopold Aschenbrenner had bought a stake in this chip giant in the third quarter of 2025. This position consisted of PUT bets worth 230,000 shares and was sold off completely by the next quarter. In addition to Leopold Aschenbrenner, other elite money managers with bearish bets on Broadcom include Ken Griffin, Israel Englander, Sander Gerber, Matthew Hulsizer, and D.E. Shaw.

Broadcom Inc. (NASDAQ:AVGO) does not sell general-purpose GPUs like NVIDIA. The AI growth of the firm is driven by designing custom AI accelerators and high-speed Ethernet networking for cloud giants. This business relies heavily on a concentrated base of six major hyperscaler customers, including Alphabet, Meta, and OpenAI, for AI revenues. Even though the AI-specific backlog sits at $73 billion, pushing AI-related revenue up to 44% of the total sales mix, short-sellers have pointed out that cloud customers are using Broadcom as a stepping stone while they build out internal engineering teams to design their own proprietary custom silicon.
