Memory is where the crowd is parked today: Micron drew 417 comments, with Sandisk and SK Hynix riding the same AI storage trade. Nvidia and Amazon are drawing arguments on both sides, Uber chatter is heating up, and Microsoft is souring fast.

Bitcoin miners owned Thursday's close, led by Marathon Digital finishing 13.5% higher, with Cipher Mining and Iren both up 7% or more. Large-cap losses ran heavier than usual, with Qualcomm off 5.66% and General Motors down 4.93%.

A single $44 million bet on Micron calls expiring October 2 is the tell: someone is positioning for a violent upside move in memory and semis within two weeks.

"Someone" just bought a boatload of short data (October2) calls Intel 115 $3.8 m; Marvell 250sm $3.8 million; Sandisk 1600s $41 million, Micron $1000s $44 million. If i didn't know any better I would say Leopold is back!!!
