Spot Bitcoin exchange-traded funds (ETFs) in the U.S. saw a shift in daily flows on Tuesday, ending a seven-day run of net inflows. Data from SoSoValue indicates that the 12 spot Bitcoin ETFs faced $79.09 million in outflows, with significant withdrawals from Ark and 21Shares’ ARKB fund, which lost $134.74 million. However, some funds still registered inflows.

BlackRock’s IBIT, the largest spot Bitcoin ETF by net assets, gained $42.98 million in net inflows, while Fidelity’s FBTC fund saw $8.85 million in positive flows. VanEck’s HODL also added $3.82 million. Meanwhile, eight other funds, including Grayscale’s GBTC, showed no net flow changes for the day. The $79 million in net outflows decreased the cumulative net inflows for all 12 spot Bitcoin ETFs to $21.15 billion. Trading activity saw a drop in total daily trading volume for these ETFs to $1.4 billion on Tuesday, down from $1.76 billion the previous day.

The outflows followed a seven-day period where spot Bitcoin ETFs attracted more than $2.67 billion, with BlackRock’s IBIT alone pulling in $1.5 billion during that time. This inflow period coincided with Bitcoin’s rally, which saw its price rise above $69,400 on Monday.

Meanwhile, U.S. spot Ether ETFs recorded net inflows of $11.94 million on Tuesday, driven entirely by BlackRock’s ETHA fund. Despite these inflows, Ether’s price dropped 0.99% to $2,611, while Bitcoin decreased 0.38%, trading at $67,038, according to data from The Block.

Bitcoin derivatives reached new heights as open interest (OI) in Bitcoin futures hit an all-time high of $40.5 billion on October 21. Data shows that the Chicago Mercantile Exchange (CME) holds the largest share of Bitcoin futures open interest at 30.7%, followed by Binance at 20.4%, and Bybit at 15%. The increase in open interest coincided with Bitcoin’s price nearing the $70,000 mark. Open interest indicates market activity and investor engagement in Bitcoin derivatives, and a rise in OI can signal increased leverage, potentially leading to greater market volatility. High open interest periods can lead to significant market movements, especially when prices change sharply.

Bitcoin spot ETF experienced a total net outflow of $79.09 million on October 22, the first net outflow after a week of net inflows. Meanwhile, Ethereum spot ETF had a net inflow of $11.94 million on the same day.
