Q2 filings show banks expanding Bitcoin ETF positions, macro funds cutting exposure and sovereign holders staying put.
itcoin fell 14.2% in the second quarter, while institutional Bitcoin ETF holdings rose 7.5% over the same period, climbing from 498,389 to 535,723 BTC equivalent. Fewer institutions drove that increase, with the number reporting Bitcoin positions through 13F filings falling roughly 6.8%, from about 2,000 to around 1,900.
Those figures are Bitcoin Strategy's second-quarter estimate, built from public 13F filings the SEC collects but does not itself aggregate this way.
CoinShares, using its methodology on the prior quarter, counted just 261,000 BTC held by professional 13F filers. It put the professional share of US-traded spot Bitcoin ETF assets at 20.8%, well below Bitcoin Strategy's 44.2% figure.
It does not establish that JPMorgan made a $356 million wager on Bitcoin's price, since a consolidated bank 13F can reflect client accounts, hedging, or exposure spread across multiple desks.
Macquarie's ordinary IBIT position fell a similar 61.78%, to 1,581,934 shares worth about $52.7 million. Macquarie also functions as an authorized participant able to create and redeem IBIT shares, the same plumbing role that complicates reading Jane Street's filing.
The bull case has the second quarter's quiet holders staying quiet, or adding, through the third quarter, while banks and wealth platforms keep building alongside them and the number of institutional filers stabilizes.
If sovereign, endowment, and advisory-platform ownership keeps expanding while spot ETF inflows turn consistently positive, Bitcoin's institutional float starts looking genuinely less reflexive during the next downturn.
The bear case has the headline institutional number staying strong for reasons that have little to do with durable demand, driven mainly by trading firms, options books, and ETF plumbing that dominate every quarter-end snapshot.
Sticky holders remain present without expanding their positions, and the next real drawdown shows how much of the second quarter's institutional total was always closer to inventory than conviction.
Bitcoin's second-quarter filings show that the institutional ownership base is already splitting into holders built to stay and holders built to trade. Only one of those groups says much about what happens the next time Bitcoin falls 14% in a quarter.
