How much Bitcoin do US ETFs hold?
US spot Bitcoin ETFs collectively hold more than 1.29 million BTC across 11 funds as of Aug. 31, 2025, according to data shared by HODL15Capital. BlackRock’s iShares Bitcoin Trust (IBIT) is the largest single fund with 746,810 BTC, followed by Fidelity’s Wise Origin Bitcoin Fund (FBTC) at just under 199,500 BTC.
Why did global ETP holdings increase since year‑end?
Between Dec. 31, 2024 and Aug. 31, 2025 global Bitcoin ETPs added roughly 170,000 BTC—about $18.7 billion at mid‑period prices—reflecting ongoing institutional adoption and the launch of multiple spot products. This accumulation concentrated supply off-exchange and into regulated fund vehicles.
How are flows changing month-to-month?
August 2025 marked a slowdown: CoinShares reported a net outflow of $301 million from global Bitcoin ETPs while Ethereum funds attracted $3.95 billion of inflows. These monthly differences show rotation across crypto products and shifting investor preference toward ETH during the period.
What on-chain signals show investor rotation?
Blockchain analytics indicate large holders are reallocating capital. Arkham reports several whales booked BTC profits and moved into ETH, with one whale selling 4,000 BTC for 96,859 ETH in a 12-hour window. Collective whale buys into ETH total roughly $456 million, according to Arkham.
When could broader ETF approvals affect demand?
Market participants are watching a backlog of roughly 92 crypto-related ETF filings with the US SEC, including proposals tracking Solana and XRP. Final decisions expected in October could reallocate capital depending on approvals and product terms.
