Top U.S. Bitcoin miners report strong May performance and infrastructure growth

Some of the biggest Bitcoin mining companies in the U.S.—CleanSpark, MARA, and Riot Platforms—just dropped their May 2025 updates, and it’s good news across the board. All three saw increases in Bitcoin production, expanded their infrastructure, and strengthened their strategies to adapt to the post-halving market. CleanSpark, in particular, had standout numbers. Basically, these miners are thriving despite the challenges of reduced block rewards.
