Wall Street $16.3B Loss in Bitcoin ETFs Ahead of Aug. 14 Filings

Institutional managers held roughly $16.33 billion in unrealized losses in U.S. spot Bitcoin ETFs as of the June 30 quarter end, based on a market-research estimate that places the average net cost basis at about $82,249. Form 13F filings due Aug. 14 will report the quarter-end ETF positions of large managers required to file under SEC rules.

SEC rules require institutional managers with at least $100 million in qualifying securities to file Form 13F within 45 days of quarter end. Those filings capture holdings as of June 30 and do not include short positions or written options. Long options can appear separately on the form, so analysts are expected to focus on common share counts rather than aggregated market values when reviewing the reports.

Flow data from a market-data provider show cumulative net inflows into U.S.-traded spot Bitcoin ETFs of about $51.6 billion since launch. The funds recorded a net inflow of $233.1 million on July 30. Between May 15 and June 3 the ETFs saw about $4.36 billion in net outflows across 13 sessions, and June as a whole recorded roughly $4.51 billion in net outflows. Through July 30, July net inflows totaled about $438 million.

BlackRock’s iShares Bitcoin Trust (IBIT) remained the largest ETF by assets, reporting net assets near $47.7 billion, about 1.3 billion shares outstanding and a year-to-date net asset value return of negative 25.94%.

An analyst at a major bank revised a 12-month Bitcoin price target to $82,000 and reduced a forecast for net ETF inflows from $10 billion to zero. That price target is close to the estimated aggregate net cost basis for ETF capital.

A simple reconciliation of the figures highlights a numerical variance: a 22% drawdown that corresponds to $16.33 billion in unrealized losses implies a capital base near $74 billion, which is larger than the roughly $51.6 billion in cumulative reported inflows.

Quarterly 13F aggregates published earlier this year showed wide differences by methodology. One aggregation counted about 1,560 institutions disclosing IBIT exposure totaling $27.6 billion, while a separate tally that excludes options put the figure closer to $12.5 billion. The discrepancy reflects how options positions can inflate gross 13F totals.

Macro conditions at the end of July included the 10-year Treasury yield near 4.74% and the 30-year yield near 5.27%, with the Federal Reserve’s policy rate target at 3.5%–3.75%. A 2025 study found that Bitcoin’s correlation with the S&P 500 rose after spot ETFs launched.

The Aug. 14 Form 13F filings will provide a quarter-end snapshot of which large managers held, added, reduced or exited spot Bitcoin ETF positions as of June 30. The filings will not reflect trading or flows that occurred after June 30, including July’s partial recovery.
