June 2026 Bitcoin Selloff Cuts $62B From Corporate Treasury Holders’ Market Caps

A June 2026 crypto selloff erased $62 billion in combined market capitalization from public companies that hold Bitcoin on their treasuries. Strategy (MicroStrategy), Tesla, and Marathon Digital were cited among the biggest drivers of the drawdown, as BTC fell roughly 50% from its peak. The move has renewed scrutiny of whether mark-to-market-sensitive corporate BTC treasury strategies can withstand sustained downside.
