Spot Bitcoin ETFs

A spot ETF holds bitcoin behind its shares

A spot Bitcoin exchange-traded fund holds bitcoin and issues shares that investors can buy through a brokerage account. The share price follows the value of those holdings, after fees and other expenses. Investors need to understand both the underlying asset and the fund’s custody and trading arrangements. BlackRock’s IBIT disclosures give one example of how these products work.

Fund flows measure money entering or leaving the products through share creation and redemption. They help show investment demand. The dollar value of a fund’s assets also changes when Bitcoin’s price moves, so assets under management and net flows answer different questions.

The latest week ended with $678.9m leaving

US spot Bitcoin funds received $21.1m on 9 October 2026, according to Farside Investors. BlackRock’s IBIT received $22.4m and VanEck’s HODL $2.3m, while Fidelity’s FBTC lost $3.6m. Across the five sessions from 5 to 9 October, the net result was $678.9m of outflows.

Cumulative net inflows since launch were $57.178bn, rounded to $57.18bn above. These are completed trading-day figures. When checked on 13 October, Farside’s 12 October row still had an unreported fund entry, so 9 October remains the latest complete session shown here. Several sessions give a better view of the direction of flows than one day alone.

Redemptions can use bitcoin or cash

Authorised participants create or redeem large blocks of fund shares under each product’s rules. In July 2025, the SEC permitted in-kind creations and redemptions for crypto exchange-traded products. An in-kind redemption can transfer bitcoin to the participant; a cash redemption uses cash. The fund’s prospectus explains the permitted arrangements.

This distinction affects how a flow reaches the wider market. A reported outflow measures a redemption from the product. Whether and when the transferred coins are sold depends on the transaction and the participant’s subsequent activity.

Compare fees, custody and trading costs

Compare a fund’s annual charge, the gap between its buy and sell prices, its tracking of Bitcoin and the custody terms. IBIT’s stated annual sponsor fee is 0.25%. Other funds have their own fees and conditions.

The Bitcoin reference places fund demand alongside a dated coin price, company holdings and the Federal Reserve calendar. Those records show what has happened; future returns depend on many sources of demand and supply.
