American Bitcoin Corp. (NASDAQ:ABTC), co-founded by Eric Trump, saw its shares rise about 10% in a single session on Wednesday after expanding its mining capacity and benefiting from a broader increase in Bitcoin (CRYPTO: BTC) prices.

Mining Expansion Boosts Capacity

American Bitcoin said it has activated approximately 11,298 additional mining machines at its Drumheller facility, adding about 3.05 exahashes per second (EH/s) of computing power at an efficiency of roughly 13.5 joules per terahash (J/TH).

The deployment completes a previously announced expansion plan.

Following the upgrade, American Bitcoin's total fleet has grown to around 89,242 miners, delivering approximately 28.1 EH/s at an average efficiency of 16.0 J/TH.

The expansion underscores the company's strategy of scaling hashrate while maintaining operational efficiency, with a focus on optimizing energy costs and deploying high-performance hardware.

Focus On Bitcoin Accumulation

Alongside operational growth, American Bitcoin has continued to build its Bitcoin holdings, accumulating about 7,000 BTC. At current prices near $79,000, the company's treasury is valued at more than $550 million.

Its holdings have grown significantly since its public debut, increasing from 2,443 BTC at its IPO in September 2025 to more than 4,000 BTC by November 2025.

While Bitcoin has gained roughly 11% over the past month, American Bitcoin shares have risen about 40.7% over the same period, reflecting investor optimism around the company's growth strategy.
