American Bitcoin Corp (Nasdaq: ABTC), a bitcoin mining company linked to Eric Trump, has significantly expanded its corporate treasury, now holding approximately 6,500 BTC, valued at around $470 million. This places the firm among the largest publicly traded bitcoin holders globally, ranking 17th out of roughly 193 public companies with bitcoin-focused treasury strategies, just behind Galaxy Digital.
The accumulation milestone was reached after the company added more than 500 BTC over a 21-day period, as announced by co-founder and Chief Strategy Officer Eric Trump in an X post on March 5, 2026. The news spurred a positive market reaction, with ABTC's stock rising 11.7% to close at $1.15 on Wednesday and gaining an additional 5.2% in pre-market trading on Thursday, though it remains down 34.3% year-to-date. The company currently has a market capitalization of roughly $1.4 billion.
This aggressive accumulation is supported by a major expansion of the company's mining infrastructure. American Bitcoin recently purchased 11,298 ASIC mining machines, expected to add about 3.05 exahash per second (EH/s) of computing capacity. Once deployed at its Drumheller site in Alberta, the company's owned fleet will reach roughly 89,242 machines, representing approximately 28.1 EH/s of hashrate.
President Matt Prusak stated the company's strategy is singularly focused, saying, "Every decision we make is oriented around maximizing bitcoin accumulation." The firm leverages its scaled mining operations to accumulate bitcoin at a cost basis below spot prices, reporting a 53% gross mining margin in Q4 2025.
Despite operational success, the company reported a net loss of $153.2 million for 2025, largely due to a $227.1 million non-cash mark-to-market loss on its bitcoin holdings under fair value accounting rules. However, it generated $185.2 million in annual revenue in its first year as a standalone public entity.
Insider confidence was demonstrated through recent share purchases by board members. Director Justin Mateen, co-founder of Tinder, acquired about 1.8 million shares on March 3. Fellow director Richard Busch purchased a total of roughly 330,000 shares across March 3 and 4.
American Bitcoin was launched in March 2025 as a majority-owned subsidiary of Hut 8, formed in partnership with Eric Trump's American Data Centers venture. It ended 2025 with 5,401 BTC on its balance sheet and has continued expanding through mining and capital markets activity, positioning itself as a critical piece of national digital infrastructure with a "miner-first" treasury model.
