Some Bitcoin mining companies are re-emphasizing their mining operations

MARA Holdings CEO Fred Thiel stated to shareholders that Bitcoin mining remains the core business of the company. Bitdeer Chief Strategy Officer Haris Basit mentioned that the company does not wish to rely on any single market cycle. Amid the sell-off of artificial intelligence stocks, some large Bitcoin mining companies that had previously shifted towards AI infrastructure are re-emphasizing their cryptocurrency business.

After the Bitcoin halving in 2024, mining profit margins are being squeezed, and several mining companies are expanding their business into AI infrastructure. Recently, IREN and CoreWeave's stock prices have plummeted, with CoreWeave's bond yields reaching junk bond levels, and Bitcoin prices have also fallen from the historical high set in October 2025.
