Justin Mateen, a board director at American Bitcoin (ABTC) — the Nasdaq-listed bitcoin mining and accumulation company backed by U.S. President Donald Trump's family — purchased approximately $1.93 million worth of the company's Class A common stock across two consecutive trading sessions on August 5–6, according to regulatory filings.
Mateen acquired roughly 145,000 shares on August 5 at an average price of $6.40 per share, totaling approximately $925,000. The following day, he purchased an additional 162,000 shares at an average price of $6.19 per share, amounting to approximately $1 million. Combined, the two transactions totaled 306,981 shares for roughly $1.93 million.
Following these purchases, Mateen beneficially owns 492,297 Class A shares of American Bitcoin, a figure adjusted to reflect the company's recent reverse stock split. Reverse splits are commonly used by Nasdaq-listed companies to regain compliance with the exchange's minimum bid price requirements.
The buying activity came shortly after the Miami-based firm released its second-quarter 2026 earnings, in which it reported a net loss of approximately $57 million alongside record mining production and continued growth in its bitcoin treasury. Open-market purchases by insiders following earnings releases are tracked by investors as one data point among many regarding insider sentiment.
During the quarter, American Bitcoin mined approximately 932 BTC — its highest quarterly output to date — and expanded its corporate treasury to more than 8,000 BTC as part of its ongoing mine-and-hold strategy. The approach of mining bitcoin and retaining it on the balance sheet rather than selling to cover operating costs has been adopted by a growing segment of publicly listed mining firms, increasing their direct exposure to bitcoin price movements.
Mateen, best known as a co-founder of the dating app Tinder, has served on American Bitcoin's board since March 2025. The company counts Eric Trump and Donald Trump Jr. among its prominent backers and has positioned itself as a vehicle for building bitcoin exposure through a combination of industrial-scale mining and direct purchases for its corporate treasury.
In a separate development earlier this week, Matt Prusak, former president and interim chief financial officer of American Bitcoin, departed the company to join Giga Energy, as reported by CoinDesk.
