IREN Jumps 6% but Then Gives Up Gains as Microsoft Accepts Horizon 1; TeraWulf Ticks Up, Cipher Digital Drops 5%
On a Friday morning while former Bitcoin miners pivoting to AI infrastructure moved on a landmark Microsoft acceptance milestone (Horizon 1), shares of Cipher Digital dropped 5% after an initial rise in IREN and a modest gain for TeraWulf.
Why it matters — CIFR watchers would note that Cipher Digital declined even as peer AI-infrastructure miners gained on the Microsoft milestone, signaling weaker relative momentum for the company.
