American Bitcoin (ABTC), a mining and treasury company linked to U.S. President Donald Trump’s family, announced Wednesday that it has added nearly 11,300 Bitcoin mining rigs at its Drumheller site. The news sent its stock price up about 12% to $1.38.
The company said the miners were fully deployed at its facilities in Alberta, Canada, increasing its ASIC (application-specific integrated circuits) fleet to approximately 89,242. It also said the new Bitcoin mining rigs contribute an additional 3.05 exahash per second (EH/s) to its current operational fleet with an efficiency of 13.5 joules per terahash (J/TH).
This high efficiency rating (13.5 J/TH) is key because it reduces the company’s cost of electricity per coin, allowing ABTC to remain profitable even as increasing network difficulties make Bitcoin more difficult to mine, the company explained in its statement. “Hashrate scaling is one of the ways we are strengthening our position in Bitcoin,” the company said.
“Bringing these miners online at Drumheller reflects exactly how we intend to lead: moving quickly, allocating capital with discipline, and efficiently growing our exposure to Bitcoin on an institutional scale,” Eric Trump, co-founder and chief strategy officer at American Bitcoin, said in a statement.
Bitcoin’s US release adds that Drumheller’s new units represent the operational completion of a fleet expansion first announced on March 3, 2026, a sign that the company has decided to double down on its bitcoin mining operations even as several other miners pivot their capital and infrastructure toward artificial intelligence and AI data centers.
On March 18, American Bitcoin increased its BTC holdings to 6,899, becoming the 16th largest Bitcoin holder, surpassing Mike Novogratz’s Galaxy Digital. On March 30, the Trump-backed company increased its BTC treasury to 7,000.
