American Bitcoin adds 3.05 EH/s on Bitmain miner buy

American Bitcoin (ABTC) reports buying 11,298 Bitmain ASIC miners, adding ~3.05 EH/s

American Bitcoin  BTC -2.47% (Nasdaq: ABTC) purchased 11,298 Bitmain ASIC miners, adding roughly 3.05 exahash per second (EH/s) at an estimated 13.5 joules per terahash (J/TH), as reported by StockTitan. The company framed the expansion as supporting network security and future readiness.

Why it matters: fleet now ~28.1 EH/s across 89,242 units

The same report indicates American Bitcoin’s owned fleet now totals approximately 28.1 EH/s across 89,242 miners. Scale at this level can lower unit operating costs if facilities, power contracts, and uptime are managed effectively.

For competitive context, Riot Platforms disclosed record annual revenue of $647.4 million amid a mixed operating backdrop for miners, as reported by Cointelegraph. Results across the sector remain sensitive to energy costs, machine efficiency, and commissioning timelines.

At the time of this writing, Bitcoin traded near $67,000 during risk-off market conditions, according to CoinDesk.

Efficiency, power, and risk context for Bitmain miners at ABTC

Reported efficiency ~13.5 J/TH and estimated power footprint implications

Based on the reported 13.5 J/TH efficiency, the new 3.05 EH/s tranche implies roughly 41 megawatts (MW) of incremental electrical load. This is derived by multiplying 3.05 million TH/s by 13.5 W/TH, which yields approximately 41.2 million watts.

Actual site-level draw can be higher due to power supply overhead, facility cooling, and power usage effectiveness (PUE). The overall fleet likely includes mixed-generation hardware, so company-wide averages may differ from the new tranche’s efficiency.

Verification notes, supply chain, tariffs, and regulatory exposure

The miner count, added EH/s, and efficiency were reported by StockTitan; the item did not specify exact Bitmain models, delivery schedule, or commissioning dates. Those details typically drive realized hashrate timing and could affect near-term capacity utilization.

According to Yahoo News, the U.S. Department of Homeland Security has reviewed security concerns related to Bitmain equipment, illustrating potential regulatory and national security scrutiny for U.S. operators sourcing Chinese hardware. American Bitcoin has publicly cast its strategy in system-resilience terms; the company said the purchase would “help protect the network and lead the future.” In a separate interview context, Bloomberg reported that American Bitcoin’s leadership has acknowledged U.S. tariffs while arguing Bitmain’s performance-per-dollar remains competitive under current chip generations.
