Top US Bitcoin Miners Report Stellar Gains in May 2025: CleanSpark, MARA, and Riot Platforms Surge Ahead

CleanSpark: Doubling Down on Infrastructure and BTC Reserves

CleanSpark is absolutely crushing it, folks! In May 2025, they mined a whopping 694 BTC and skyrocketed their hashrate to 45.6 EH/s, a solid 7.5% jump from last month. But that's not all—they're now sitting on a treasure trove of 12,502 BTC, double what they had just a year ago, and every single coin was mined by them. No buying here, just pure mining power!

And they're not slowing down. CleanSpark just boosted their contracted power capacity to a mind-blowing 987 megawatts. They're on a mission to be the first public miner to hit 50 EH/s with all self-operated infrastructure. It's like watching a rocket take off!

CEO Zach Bradford is fired up, saying their infrastructure-first approach is set to scale beyond 60 EH/s while keeping everything under their control. This is next-level stuff!

MARA: Post-Halving Powerhouse

MARA is not playing around either. They just reported their best month since the April 2024 halving, mining 950 BTC in May—a massive 35% increase from April. They also smashed it with 282 blocks, up 38% from the previous month. It's like they're on a winning streak!

And get this: MARA's BTC stash is now over 49,000, thanks to their self-operated MARA Pool, which is killing it with above-average block reward "luck" and top-notch operational efficiency. It's like hitting the jackpot!

CEO Fred Thiel is all about that vertically integrated life, saying it's the secret sauce to slashing costs and maximizing energy use. It's like they've got the cheat code to mining!

Riot Platforms: Mining and Data Centers on Fire

Riot Platforms is also on a roll, mining 514 BTC in May—an 11% increase from April. But they're not just mining; they're investing big time in their data center game.

They just locked in 355 acres near their Corsicana site in Texas to build some seriously high-performance computing data centers for enterprise and hyperscale clients. And they've brought in Jonathan Gibbs, a total boss in the field, as their new Chief Data Center Officer to lead this epic expansion. It's like they're building the future!

Post-Halving Power Plays

These three giants are not messing around in the post-halving world. They're all in, doubling down on infrastructure, vertical integration, and smart treasury management. It's like watching the heavyweight champs of crypto go head-to-head, and we're here for it!
