American Bitcoin (ABTC), a mining and treasury company linked to US President Donald Trump’s family, announced on Wednesday that it had added nearly 11,300 bitcoin mining rigs to its Drumheller site. The news sent its share price up about 12% to $1.38.
The company said miners were fully deployed at its facilities in Alberta, Canada, increasing its fleet of ASICs (application specific integrated circuits) to approximately 89,242. It also said that the new bitcoin mining rigs bring an increase of 3.05 exahash per second (EH/s) with an efficiency of 13.5 joules per terahash (J/TH) to its current operational fleet.
This high efficiency rating (13.5 J/TH) is critical because it reduces the company’s electricity cost per coin, allowing ABTC to remain profitable even as increasing network difficulty makes Bitcoin more difficult to mine, the company explained in its statement. “Increasing the hash rate is one of the ways we strengthen our position in Bitcoin,” the company said.
“Putting these miners online at Drumheller reflects exactly how we intend to lead: move quickly, allocate capital with discipline, and grow our exposure to Bitcoin efficiently on an institutional scale,” said Eric Trump, co-founder and chief strategy officer of American Bitcoin, in a statement.
American Bitcoin’s statement added that the new units at Drumheller 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 shift capital and infrastructure to AI 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.
