CleanSpark Sinks 6% Even as Bitcoin Jumps 7%, MARA Holds Flat as Traders Weigh Tensions Among AI Miners

CleanSpark's stock declined 6% as Bitcoin rose 7%, while MARA holdings remained flat amid skepticism over the shift from mining to AI data center operations. Riot Platforms' $9.1 billion deal with Anthropic failed to gain, and the WGMI ETF dropped 3% with Bitcoin's surge. CleanSpark's $6.6 billion lease at Sandersville remains unfulfilled, with mining revenue falling 30% and EBITDA turning negative.

The split within the Bitcoin miner cohort is evident, with CleanSpark suffering while MARA holds steady. The market now values CleanSpark's promises based on confirmed anchor tenants, not just construction milestones. The CoinShares Valkyrie Bitcoin Miners ETF also fell 3%, highlighting the disconnect between the miner and Bitcoin trends.
