American Bitcoin has significantly expanded its mining operations by adding nearly 11,300 rigs at its Drumheller site, increasing its total fleet to 89,242 ASIC units. This expansion has boosted the company's hashrate by 3.05 exahash per second (EH/s), operating at an efficiency of 13.5 joules per terahash (J/TH). The announcement led to a 12% rise in American Bitcoin's stock, reflecting investor confidence in the company's growing capacity and operational scale. The company emphasized its strategy of low-cost Bitcoin accumulation, mining at a 53% discount to spot prices in the fourth quarter of 2025. This approach has increased its Bitcoin holdings to 7,000 BTC by March 30, positioning it as the 16th-largest corporate Bitcoin holder. Co-founder Eric Trump highlighted the disciplined capital approach and the focus on expanding Bitcoin exposure at an institutional scale. The expansion aligns with industry trends towards efficiency and long-term accumulation, especially as the next Bitcoin halving in April 2028 is expected to tighten supply further.
