American Bitcoin shareholders got a signal of insider confidence on August 10, 2026, when Simply Wall St reported that independent director Justin Mateen had spent roughly $1.9 million buying more ABTC stock.
Mateen, a co-founder of Tinder and an ABTC board member since March 2025, made the purchase at an average price of $6.29 per share, boosting his holding by 166%. The buy came against the backdrop of a rough stretch for the company’s stock.
The Largest Insider Buy in a Year
Simply Wall St reported that this was the largest single purchase by an American Bitcoin insider in the past twelve months, made close to the stock’s current trading price of $6.47 rather than at a steep discount. Insiders have bought steadily over that period and have not sold a single share, and they now hold about 7.1% of the company, worth an estimated $34 million.
Why the Timing Stands Out
Mateen’s purchase lands during a stretch that has been brutal for American Bitcoin shareholders. According to Bloomberg’s calculations, shares have fallen more than 95% from their peak, erasing over $600 million from the market value of Eric Trump’s stake over the past 10 months.
The company posted a third consecutive quarterly loss in early August after a decline in the value of its Bitcoin holdings, the kind of backdrop that makes an insider committing nearly $2 million of his own money worth a second look for anyone tracking the bitcoin mining and treasury sector.

The Next Filing Window to Watch
Mateen also received a grant of 46,404 restricted stock units on July 29, separate from this week’s open-market buy. Whether fellow director Richard Busch, who has bought shares after past earnings reports, makes a similar move before the next filing deadline is the detail worth watching.
What this means for you: an insider spending nearly $2 million of his own money on a stock that’s down more than 95% from its peak is a signal of confidence, not a guarantee, so treat it as one data point rather than a reason to buy.
