Is MARA Stock A Buy Today, Before Any AI Leases Are Signed?

The hopeful view of MARA (MARA) is that it is becoming a power and data center business, not only a Bitcoin miner. Management expects its power portfolio to reach about 4.8 gigawatts once pending deals close, more than double today's capacity. For that to pay off, the deals must close and turn into AI leases, and MARA's Bitcoin must carry it until then. The Long Ridge power deal looks close to a decision. The Bitcoin cushion is holding, but much of it is now pledged against loans.
