The tweet discusses a potential "hit piece" from SemiAnalysis targeting IREN (Iris Energy) regarding cooling infrastructure at its Childress site. The author notes that short interest in IREN has risen from 15% to 22.51% since May, but expects the bearish sentiment to be dispelled by the late July handover of the H1 site to MSFT (Microsoft). The post also mentions previous reports on Nvidia and the upcoming GB300 exemplar status.
