End of bitcoin 'HODL': public miners going all-in on AI, signaling more BTC selling

Public bitcoin miners shift capital from bitcoin treasuries to AI infrastructure; Core Scientific sold almost 1,900 BTC and disclosed $175 million in bitcoin sales as it transitions to AI, Marathon Digital expands policy to permit balance-sheet bitcoin sales after reporting a $422.2 million fair-value decline for 2025, and Riot Platforms increases owned mining capacity to 28.1 EH/s while holding 18,005 BTC — companies did not disclose total reallocated capex to AI.
