Bitcoin spot ETFs showed a split picture this week. Total weekly net outflows came in at $305 million, yet the category still recorded $95 million in inflows. Data cited from SoSoValue points to a market where short-term selling and continued allocation happened at the same time, leaving sentiment mixed rather than outright negative.
BlackRock's IBIT accounted for the largest share of withdrawals
The biggest source of pressure came from BlackRock's iShares Bitcoin Trust, or IBIT. The fund posted $116 million in outflows, the largest withdrawal among all products tracked in the report. Other Bitcoin ETFs also saw money leave, though none matched the scale recorded by IBIT during the week.
That did not erase demand completely. Fresh inflows still offset part of the redemptions, suggesting that one group of investors was taking profits while another kept adding Bitcoin exposure through listed funds.
Outflows lined up with BTC's move above $70,000
The timing of the withdrawals matched a sharp move in Bitcoin's price. BTC climbed above $70,000 and reached roughly $71,300 on March 20, the weekly high cited in the source material. At the same time, continuous outflows were reported on March 18, 19, and 20, indicating that rising prices triggered selling from holders locking in gains.
Regulatory news added another layer of pressure. Developments tied to the Digital Asset Clarity Act were described as a source of short-term uncertainty, shaping trading behavior and weighing on sentiment during the same period.
Momentum fell sharply from earlier March levels
The slowdown stands out even more against prior weeks. Earlier in March 2026, weekly Bitcoin ETF inflows averaged around $767 million. This week's $95 million marks a steep drop in pace, even though flows remained positive overall.
Ethereum spot ETFs faced a similar pattern. Weekly net outflows totaled $41.97 million, with a large portion tied to BlackRock's ETHA fund. The source described the same driver in both markets: price gains encouraged investors to sell into profit, reducing net inflows across crypto investment products.
BTC slips to $68,400 as total crypto market cap nears $2.35 trillion
After the weekly peak, Bitcoin fell back to around $68,400. Total crypto market capitalization stood near $2.35 trillion, down 0.97% over 24 hours. The report noted that the market had shown signs of recovery in the previous week, helped by improving global conditions and renewed demand, while the latest move looked more like a correction than confirmation of a longer downturn.
The source also cited analyst views that the market may already have tested its weak point, lowering the odds of another sharp leg down. What the flow data shows for now is a market under pressure but not in retreat across the board: ETF buying is still present, though far below the stronger levels seen earlier in the month.
