Per Woofun AI data, a large investor established a $21.2 million bearish position on Micron by acquiring MU $900 put options expiring on June 26, 2026. The trade involved a premium of $21.23 million, with a total trading volume of 7,311 contracts against an open interest of 3,909, leaving the options 13% out-of-the-money.

Notably, over 84% of the transaction volume executed at the ask price, reflecting aggressive demand for downside protection. Since the position size surpassed existing open interest, this indicates a fresh bearish bet rather than a transfer of existing positions. The premium appreciated steadily throughout the session, closing near its daily high, marking this as one of the most significant semiconductor put option trades observed today.
