Companies that once filled warehouses with computers to earn Bitcoin - a process known as mining - are now using that computing power for AI.
Bitcoin mining companies invested large sums on giant banks of powerful computers as the price of Bitcoin rocketed in recent years.
But those mining companies have faced falling rewards since the value of the cryptocurrency has slumped from its peak in October 2025.
Now many are pivoting to AI and signing deals with companies such as Anthropic - who are spending billions of dollars on the infrastructure needed to keep up in the AI race.
