According to ChainCatcher, citing SoSoValue data, U.S. spot Bitcoin ETFs recorded a combined total net outflow of $90.6566 million on June 18 Eastern Time. The figure represents the net result after daily inflows and outflows across the spot Bitcoin ETF group were calculated for that reporting date.
MSBT Posts the Largest Daily Net Inflow
Among the listed spot Bitcoin ETFs covered in the data, the Morgan Stanley ETF MSBT recorded the largest single-day net inflow. SoSoValue data showed that MSBT brought in $10.4337 million in net inflows on the day. After including the June 18 flow, MSBT’s historical total net inflow reached $301 million.
MSBT’s daily inflow placed it at the top of the spot Bitcoin ETF group for net positive flows on that specific trading day. However, the broader category still ended the day with a combined net outflow, as total outflows across other products outweighed the inflows recorded by MSBT and any other funds in the group.
BlackRock’s IBIT Leads Daily Net Outflows
The spot Bitcoin ETF with the largest single-day net outflow was BlackRock’s IBIT. According to the same SoSoValue dataset, IBIT recorded a daily net outflow of $96.6552 million on June 18 Eastern Time. Despite that daily outflow, IBIT’s historical total net inflow stood at $62.07 billion.
As of the time of publication, the total net asset value of spot Bitcoin ETFs was $78.325 billion. The ETF net asset ratio, defined in the source data as the share of spot Bitcoin ETF market value relative to Bitcoin’s total market value, stood at 6.19%. Historical cumulative net inflows into spot Bitcoin ETFs had reached $53.398 billion.
