American Bitcoin Corp., a bitcoin mining and treasury company backed by Donald Trump Jr. and Eric Trump, made a striking debut on the Nasdaq on September 3, 2025, following its merger with Gryphon Digital Mining. Trading under the ticker ABTC, its shares skyrocketed by as much as 110 percent intraday before settling with a 16.5 percent gain, closing at $8.04—a valuation that placed the company’s worth at around $7 billion. At the peak price, the Trump brothers—who collectively own roughly 20 percent of the company—saw their stake valued at up to $2.6 billion, though the closing-day value was estimated at $1.5 billion.
American Bitcoin, a spin-off from American Data Centers, benefits from a strategic partnership with Hut 8 Mining, which supplies mining infrastructure and holds an 80 percent ownership stake in the new entity. The company has already amassed 2,443 bitcoins as part of its combined mining and treasury strategy and has plans to raise $2.1 billion through a stock offering to fund further bitcoin purchases and mining expansion. While supporters highlight the transparent accumulation of bitcoin and the company’s vertically integrated mining model, critics raise concerns about potential conflicts of interest—especially given President Trump’s efforts to ease crypto regulation during his second term—as the Trump family continues to diversify its crypto footprint, including ventures such as World Liberty Financial and branded tokens.
