Shares of American Bitcoin Corp. (ABTC) surged today after the company announced it had completed the energization of more than 11,000 new mining machines at its Drumheller facility, significantly expanding its operational capacity.
The company said it has brought approximately 11,298 additional ASIC miners online, adding about 3.05 exahashes per second (EH/s) to its active hashrate. The deployment marks the completion of a previously announced expansion plan and pushes American Bitcoin’s total operational fleet to roughly 25.0 EH/s across nearly 59,000 active machines.
Including inactive inventory, the firm now owns about 89,242 miners capable of producing up to 28.1 EH/s, positioning it among the more aggressive scale-up stories in the public Bitcoin mining sector.
The newly deployed machines operate at an efficiency of roughly 13.5 joules per terahash, improving the overall performance of the fleet. Post-expansion, the company’s operational efficiency averages around 14.1 J/TH, while its full owned fleet averages approximately 16.0 J/TH.
“Scaling hashrate is one of the ways we strengthen our position in Bitcoin,” said Eric Trump, co-founder and chief strategy officer of the company. He added that the deployment reflects a strategy focused on disciplined capital allocation and rapid execution to grow Bitcoin exposure at scale.
ABTC shares surge along with Bitcoin
The announcement triggered a sharp market reaction, with ABTC shares jumping double digits in early trading. The rally extends a broader upward trend in the stock, which has gained significantly over the past month as investors respond to both operational growth and rising Bitcoin prices.
American Bitcoin, a majority-owned subsidiary of Hut 8 Corp., operates with a business model centered on accumulating Bitcoin through self-mining rather than simply selling production into the market. The company has emphasized producing Bitcoin at costs below spot prices, a strategy it says enhances long-term shareholder value.
The Drumheller expansion is part of that approach, combining hardware efficiency with energy cost optimization. By increasing hashrate while maintaining relatively low operating costs, the firm aims to scale its Bitcoin holdings per share.
American Bitcoin said the Drumheller deployment represents the operational conclusion of its March expansion plan, signaling a shift toward optimizing output from its enlarged fleet rather than adding immediate new capacity.
On top of this, Bitcoin has surged above $79,000 and Strategy’s stock surged over 25% in five days amid the company’s aggressive accumulation strategy. The firm purchased 34,164 BTC for $2.54 billion, bringing its total holdings to 815,061 BTC and making it the largest corporate holder of Bitcoin.
