Matt Prusak, president and interim chief financial officer of Trump-linked bitcoin miner American Bitcoin (ABTC), is leaving the company to join AI and energy infrastructure developer Giga Energy, marking another senior executive move toward the power sector that is increasingly underpinning both bitcoin mining and artificial intelligence.
Prusak said he will step down from American Bitcoin effective Aug. 4 and join Giga Energy as chief business officer and interim CFO.
He said in emailed comments that after “years building bitcoin businesses,” he was shifting “upstream to the power infrastructure now constraining both mining and AI compute.”
The departure reflects a broader shift as bitcoin miners reposition around AI and power infrastructure. As mining becomes increasingly commoditized and margins come under pressure, a growing number of miners are pivoting toward artificial intelligence infrastructure, repurposing their power, land and data center expertise to serve the surging demand for AI compute.
The shift has accelerated as hyperscalers race to secure electricity and capacity, allowing mining companies to diversify revenue beyond bitcoin production and tap the higher valuations being awarded to AI infrastructure businesses.
