MARA Fell 4% as Riot Landed a $28 Billion AI Lease. Here’s What November 9 Must Show
MARA Holdings (MARA) fell 4% on Nov. 4, while Riot Platforms (RIOT) rose 10% after securing a $28B AI lease. MARA's upcoming earnings report must show its power can generate more than bitcoin mining. Cipher Digital (CIFR) dropped 20% despite its leases, and IREN's AI cloud revenue was seven times its mining revenue. MARA trades at a discount until it signs a tenant.
