Justin Mateen, a director at American Bitcoin Corp. (**NASDAQ: $ABTC), acquired 162,438 shares of the company's stock in an open-market transaction on August 6, 2026. The purchase was executed at a price of $6.19 per share, yielding a total transaction value of $1,005,053, according to a Form 4 filing with the Securities and Exchange Commission dated August 7, 2026.
The transaction followed a separate open-market purchase by Mateen on August 5, when he bought 144,543 shares at $6.40 per share, totaling $924,555. The combined dollar value of the two-day buying reached approximately $1.93 million. Both trades were included on the same Form 4 filed on August 7, meaning the August 5 trade was reported two days after execution and the August 6 trade was reported the following day.
On August 5, $ABTC shares traded in a range of $6.08 to $6.61 and closed at $6.54. The following day, the stock opened at $6.38, traded between $6.09 and $6.42, and closed at $6.19 — the same price at which Mateen's purchase was executed.
Following the August 6 purchase, Mateen's direct holdings in American Bitcoin Corp. stood at 492,297 shares. The shares-owned-after figure from the August 5 purchase was 329,859, indicating that Mateen held approximately 185,316 shares prior to the two-day buying sequence.
The August trades represent Mateen's only disclosed $ABTC purchases since March 3, 2026, when he acquired 1.8 million shares at $1.03 per share in an open-market transaction valued at $1.85 million. Across all three $ABTC transactions captured in SEC filings, Mateen has deployed roughly $3.78 million into the stock.
American Bitcoin Corp. has seen limited insider transaction activity beyond Mateen in 2026. Director Richard Busch executed a series of open-market purchases in early March 2026, acquiring shares across multiple days at prices between $0.96 and $1.15. Busch also made purchases in December 2025 at prices ranging from $1.66 to $1.98 per share. The last insider sales on record for $ABTC occurred in September 2025, when Anchorage Lending CA, LLC — listed as a director in its Form 4 filings — executed three open-market sales at prices between $7.36 and $9.20 per share. No other insider has filed a Form 4 for $ABTC transactions in 2026 outside of Mateen and Busch.
American Bitcoin Corp., classified in the technology sector, carried a market capitalization of approximately $402 million at the time of the transactions. A review of STOCK Act filings shows no congressional trades involving $ABTC.
Mateen's Form 4 filing history indicates that all three of his disclosed $ABTC transactions — the two August 2026 purchases and the March 2026 purchase — were open-market acquisitions. The shares-owned-after totals reflect his cumulative position as a director of the company.
