American Bitcoin president Matt Prusak to exit for Giga Energy on Aug. 4
The interim CFO will take commercial and finance roles at the Houston power-and-AI infrastructure developer.
Matt Prusak will step down as president and interim CFO of American Bitcoin effective Aug. 4, 2026, and start at Giga Energy the same day as chief business officer and interim CFO. The move puts a senior mining executive directly into the power-and-data-center layer that is increasingly setting the ceiling for both hashrate growth and AI compute buildouts.
Matt Prusak is leaving American Bitcoin as president and interim chief financial officer effective Aug. 4, 2026. He is joining Houston-based Giga Energy on Aug. 4 as chief business officer and interim CFO.
American Bitcoin is described as a Nasdaq-listed mining company backed by Hut 8 (HUT) and co-founded by Eric Trump. Prusak has been one of the public faces of the company’s bitcoin accumulation strategy, regularly pointing to a dual focus: expanding hashrate while increasing BTC holdings per share.
The catch for traders is what is not in the handoff. No successor for the president/interim CFO roles is identified in the provided details, and there is no explicit reaffirmation of American Bitcoin’s capital allocation priorities post-transition. That leaves a near-term continuity gap until American Bitcoin clarifies who owns the strategy and the balance sheet decisions.
Prusak framed the move as a deliberate shift in where the bottleneck sits. He said in emailed comments that after “years building bitcoin businesses,” he is moving “upstream to the power infrastructure now constraining both mining and AI compute.”
Power Infrastructure Is the New Chokepoint for Both Mining and AI Buildouts
Giga Energy is positioning itself as a developer and manufacturer of power equipment and AI data center infrastructure. The company says it has delivered more than 6.5 gigawatts (GW) of power infrastructure and is developing more than 500 megawatts (MW) of AI-ready data center capacity.
Those scale claims matter because they explain the counterparty to the talent shift. If mining is increasingly commoditized and margins are under pressure, the economic rent migrates to whoever controls interconnection, generation, and buildable capacity. Electricity becomes the binding constraint, and the firms that can deliver power and data center infrastructure get to price scarcity.
The broader setup described here is miners repurposing what they already have, namely power access, land, and data center operating experience, toward AI infrastructure to diversify revenue beyond bitcoin production. The acceleration point is hyperscalers racing to secure electricity and capacity, which has supported higher valuations for AI infrastructure businesses and pulled executive talent toward the upstream layer.
The forward-looking signal is not just “mining to AI.” It is “mining to power.” AI compute is ultimately a power procurement and delivery problem dressed up as a chip story, and bitcoin mining’s expansion path runs into the same wall. When a president/interim CFO moves from a miner into a power-and-data-center supplier, it is a clean tell on where management teams think the constraint will price.

The threshold that matters is Aug. 4, 2026. Confirmation of Prusak’s exit and start date is table stakes, but the real test is whether American Bitcoin names an interim or permanent replacement quickly and uses that moment to reaffirm, tweak, or quietly de-emphasize its bitcoin accumulation strategy.
Giga Energy’s stated 6.5 GW delivered and 500 MW in development are the other fulcrum. If those numbers get corroborated with customer announcements or project timelines, the move reads structural rather than narrative-driven, and it reinforces the market’s tendency to re-rate power and AI data center infrastructure over pure-play mining when electricity is scarce.
