- Cash creations mean the fund buys the crypto itself.
- Daily flow reports net creations against redemptions.
- A creation unit is a large block, usually 50,000 shares.
A daily headline might say a spot bitcoin ETF took in money, or lost it. The figure comes from the fund's share count, not from the exchange where you place an order.
What ETF inflows and outflows mean
An inflow is a net increase in a fund's shares, and for a spot crypto fund those new shares come with more bitcoin or ether. An outflow is a net decrease, and the holdings drop with it.
How creation and redemption works
Authorized participants are large broker-dealers that deal with the issuer directly. An ordinary investor never creates or redeems ETF shares. The first US spot bitcoin ETFs, approved in January 2024, used cash creations, so the fund bought the crypto itself. Check a fund's prospectus for its method.
- 1Request a creation unitThe participant orders a block of new shares, generally 50,000.
- 2Deliver cash or cryptoIn a cash creation the participant pays dollars, and the fund buys the crypto.
- 3Receive the sharesThe issuer credits the shares, and they trade on the exchange.
- 4Redeem the sharesA redemption runs in reverse: shares go back to the issuer, and it pays cash or crypto.
How to read daily flow reports
Data providers publish a daily net figure for US spot crypto ETFs, a practice that began after the first US spot bitcoin ETFs were approved in January 2024. The figure adds creations and subtracts redemptions, and it does not set the price of bitcoin or ether.
- A positive figure means net creations; a negative figure means net redemptions.
- Keep flows apart from trading volume.
- Read the date, since a cash-created fund may buy the crypto later.
