IBIT shares = shares (not options or notes) reported under CUSIP 46438F101 in the filer’s 13F report for the quarter, summed over the filing.1 Share of IBIT = shares ÷ IBIT’s shares outstanding on the date; bitcoin-equivalent = shares × the trust’s bitcoin per share (0.000564 at June 30), from BlackRock’s holdings file.2 Reported value is the filer’s figure in dollars. Where a filer also filed an amendment, the original report is used. Option positions on IBIT, which several filers also report, are excluded. A 13F filer reports holdings it has investment discretion over, which can include client accounts, funds it manages and positions it holds to hedge or trade; the filing does not say which. Filers that list other managers in a combination report may overlap with those managers’ own reports, so totals are not de-duplicated across filers. Observed facts, not a forecast.
Form 13F is the quarterly report in which institutional investment managers that exercise investment discretion over $100 million or more in qualifying securities list their holdings, so smaller and individual holders are not in it.3 At March 31, 2026, 1,521 filers reported 341,881,717 IBIT shares, 24.8% of the 1,379,920,000 outstanding; at June 30, 1,466 reported 346,229,740, 26.6% of 1,302,440,000.12 For the fund’s daily flows, see the largest IBIT flow days, and for its size against other funds, the largest spot bitcoin ETFs.
