Overview
- Matt Prusak said he will leave his roles as president and interim chief financial officer of Nasdaq-listed American Bitcoin to join Houston-based Giga Energy as chief business officer and interim CFO, a change reported as effective Tuesday.
- American Bitcoin named Paul Sacks as its interim CFO beginning August 4 and disclosed Prusak notified the company of his decision on July 30, while it has not announced a replacement for the president role.
- Prusak was a public face of American Bitcoin’s accumulation strategy and infrastructure buildout, and his exit follows a string of departures as ABTC’s shares have fallen sharply over the past year.
- Giga Energy says it has delivered more than 6.5 gigawatts of power infrastructure and is developing over 500 megawatts of AI-ready capacity, though analysts warn converting that pipeline to operating AI data centers requires large capital, long equipment lead times and favorable power contracts.
- The hire highlights a broader industry shift in which miners and executives repurpose land, power deals and data-center skills toward AI compute and modular power solutions, a trend that could change where and how large compute projects secure electricity and funding.
