What remains central to a mining company when another infrastructure market weakens? In a report published November 13, 2026, at 11:05:56 UTC+8, ChainCatcher said some large Bitcoin miners that had expanded into AI infrastructure were again emphasizing their cryptocurrency businesses amid an AI stock sell-off.
MARA Holdings CEO Fred Thiel told shareholders that Bitcoin mining remained the company’s core business. Bitdeer chief strategy officer Haris Basit said the company did not want to depend on any single market cycle.
The report placed those remarks against the margin pressure miners faced after Bitcoin’s 2024 halving, which had prompted several firms to expand into AI infrastructure. It also reported sharp recent share-price declines for IREN and CoreWeave, said CoreWeave’s bond yield had reached junk-bond levels, and noted that Bitcoin had fallen from its October 2025 record high. It did not provide mining-cost figures or quantify the effect of those market moves on either miner’s operations.
