Riot Platforms, Inc.
A bitcoin mining and digital infrastructure company that runs massive data centers in Texas and Kentucky, mines bitcoin with specialized ASIC machines, and builds power-distribution equipment for industrial and government customers. It began life in 2000 as Bioptix, a medical diagnostics firm, before pivoting to crypto in 2017 and renaming itself Riot Blockchain, then Riot Platforms in 2023. Its Nasdaq ticker stayed "RIOT" through all the name changes.
