πŸ“° Key Takeaways

Core Scientific announced that it expects to exit bitcoin mining entirely by the end of 2026 and become a pure high-density colocation data center operator focused on artificial intelligence and high-performance computing infrastructure. CFO Nygaard said on the Q3 earnings call that the company will finish winding down in Q4 and enter 2027 as a pure colocation provider. The company had already disclosed in its July quarterly report that its hosting business for other people’s mining would end on December 31, and this is the first time it has set a timeline for fully exiting mining. By the numbers, the transition is already well advanced: Q3 total revenue was $232.9 million, of which colocation services made up $215.4 million, while bitcoin mining contributed only $17.5 million, or 7.5%. Self-mining revenue fell from $57.4 million a year earlier to $12.3 million, and revenue from hosting miners for others dropped from $8.7 million to $5.2 million. As of the end of September, the number of online miners was down nearly 50% from the end of 2025. Looking back, the company signed an initial colocation agreement with CoreWeave in March 2024 and announced a larger contract in June, when it still stressed that it was keeping its mining capacity; by December 2025, the Wall Street Journal had reported that it aimed to end mining by 2028. In Q1 2026, with bitcoin prices weak, hashprice at record lows, and the value of used mining rigs declining, the company recognized a $266.5 million impairment on mining-related assets; in Q2 it terminated its miner agreements with Block and Proto, booking a $41.9 million loss. In addition, after the US midterm elections, candidates opposing data center development benefited from a big Democratic win, as rising electricity bills and large facilities taking up local resources have sparked backlash, adding uncertainty to the AI infrastructure buildout.

πŸ’¬ JudyAI Lab Take

Core Scientific announced it will fully exit bitcoin mining by the end of 2026 and become a pure colocation data center operator for AI and high-performance computing. Q3 total revenue was $232.9 million, and mining contributed just $17.5 million, or 7.5%. By the numbers, the company has basically already made the turn.

For AI builders, this case shows that the center of gravity in compute infrastructure is shifting. The same data halls, power, and cooling that used to serve mining now serve AI and HPC, and the company was willing to take a $266.5 million impairment and terminate its miner agreements with Block and Proto, which is not a small price. On the other hand, the original article also mentions backlash over rising electricity bills and large facilities taking up local resources, and that candidates opposing data center development benefited after the US midterms. So the AI infrastructure buildout isn’t going to be a smooth ride. Compute supply is tied to power, land, and local politics, and all of that affects the cost and stability of the compute we can get.

When planning AI products, I’d put compute sourcing and cost volatility on your risk list, and consider whether you need to keep the flexibility to work across multiple providers.
