The Biggest Bitcoin Miner of an Era Is Quitting: Income Increased by 60 Percent in His New Job

Core Scientific plans to wind down its proprietary Bitcoin mining entirely by the fourth quarter of 2026 and operate solely as a high-performance computing infrastructure provider from 2027, according to its third-quarter earnings call as reported by Wu Blockchain. The pivot marks the exit of one of the largest former Bitcoin miners from self-mining, with the company's new HPC business already delivering a 60% revenue increase. The shift reflects the sector's broader migration toward AI and HPC hosting as hashprice economics pressure pure-play mining margins. Investors should watch Core Scientific's contracted HPC capacity and client agreements through 2026, plus the pace at which it converts remaining mining sites to data-center use ahead of the 2027 transition.
