A fund's flow is the day's change in the coins it holds, in dollars. Rising holdings mean the issuer created shares and bought coin to back them; falling holdings mean it redeemed shares.

IBIT iShares -2,128.69 BTC -$161.20 million 784,525.64 BTC

BITB's second redemption in a week

BITB redeemed 162.78 BTC, almost exactly the 162.79 BTC that left on Thursday, September 10. It holds 38,029.22 BTC, worth about $2.90 billion, and that's still 276.64 BTC more than on August 21. IBIT holds 20.63 times as much bitcoin.

ARK 21Shares' ARKB starts its history on the ETF flows page on September 15, holding 32,095 BTC, and has no flow for the day.
