Bitcoin’s $16.3 billion Wall Street stress test splits into four positional patterns

Summary

Five 13F filings after Q2 show four distinct Bitcoin ETF responses to June’s drawdown. Mubadala and Abu Dhabi Investment Council kept IBIT share counts flat, but reported values fell about 13.35%, indicating price revaluation rather than net selling. JPMorgan increased ordinary spot-ETF holdings, mainly IBIT, while also raising disclosed IBIT call exposure and cutting put exposure. UBS raised spot holdings and sharply shifted its long-options mix, with IBIT call equivalents jumping and puts falling. Morgan Stanley reduced external spot-ETF units but added a new Bitcoin Trust wrapper in its filing, so the net change across products is not fully comparable. The filings freeze positions at June 30 and 13F excludes shorts and written options, so they show only partial books. Meanwhile, the Bitcoin ETF complex saw about $4.89 billion of Q2 net outflows, including about $2.06 billion in June’s final five sessions. No filing proves a forced liquidation; the data instead show that the same ETF stress was absorbed through different structures, owners, and instruments.
