Core Scientific paid $41.9 million to terminate a bitcoin miner contract with Block and its Proto unit, the company disclosed this week. The move marks another step in the publicly traded miner's (NASDAQ: CORZ) accelerating retreat from bitcoin mining toward AI infrastructure.
The termination deal
The $41.9 million payment ends an agreement with Block's Proto division, which supplies mining hardware. Core Scientific did not specify how many machines were covered or when the contract was originally signed. The termination fee suggests a significant commitment was being unwound.
Why Core Scientific is pivoting
The company has been shifting resources toward AI infrastructure, a trend seen across the mining sector. Core Scientific's pivot isn't new — it has been converting mining facilities to host high-performance computing for AI workloads. This contract exit accelerates that strategy. The timing isn't great for bitcoin miners still recovering from the 2024 halving, but Core Scientific appears to be betting on AI demand over bitcoin rewards.
What this means for Block
Block's Proto unit has been developing its own mining chips and systems. Losing a customer like Core Scientific — one of the largest publicly traded miners — is a blow. Block hasn't commented on the termination, but the lost revenue could slow its hardware rollout. The $41.9 million payment softens the hit, but it doesn't replace a long-term contract.
The story was first reported by The Energy Mag, formerly The Miner Mag. Core Scientific's retreat from mining mirrors moves by other operators who are repurposing power and infrastructure for AI. The question now is how fast the transition can happen — and whether AI revenue can replace mining income at scale.
Core Scientific hasn't announced new AI contracts or further mining exits. Investors will be watching for its next quarterly report for clues on the pace of the pivot.
