Bitcoin has just suffered a slide of over 20% from its May peak, while ETF flows are drawing significant attention in the market. U.S. spot Bitcoin ETFs recorded a 12-day streak of net outflows as of June 2, the longest outflow streak since this group of products began trading in the U.S. In total, nearly $4 billion has left the ETFs during this period, while BTC dropped from the peak area around $84,600 to about $66,800.
Nearly $4B Leaves U.S. Spot Bitcoin ETFs
According to SoSoValue data, nearly $4 billion left U.S. spot Bitcoin ETFs during the outflow streak lasting from May 15 to June 2. This 12-session streak also surpassed the previous outflow record of the fund group, marking the longest withdrawal period to date. The scale of these withdrawals shows that the pressure did not come from a single day of redemptions, but occurred continuously across the entire product group.

The heaviest outflow session was May 27, when the funds recorded approximately $733 million in net outflows. BlackRock’s IBIT alone accounted for about $528 million, making the market’s largest Bitcoin ETF the focal point of this outflow session.
The final two sessions of the streak continued to record large outflows, with about $484 million leaving the funds on June 1 and about $519 million on June 2. During the same period, the total net assets of the spot Bitcoin ETF group decreased from around $104.3 billion in mid-May to around $94.2 billion at the end of the month, reflecting both the impact of the outflows and the decline of BTC.
ETF Demand Turns From Tailwind to Pressure Point
Spot Bitcoin ETFs were once one of Bitcoin’s most important sources of demand after they began trading in the U.S., helping traditional investors access BTC through brokerage accounts and listed products. Therefore, ETF flows are often viewed by the market as an indicator of demand through institutional and traditional financial investment channels.
With 12 consecutive trading sessions, this outflow streak has changed that narrative. Instead of continuing to support the price, ETF flows are becoming a source of pressure on market sentiment.
However, outflows from ETFs do not mean all institutional investors have abandoned Bitcoin. Net flows only reflect the capital entering and leaving ETF products, excluding spot, futures, or direct custody transactions. A portion of the outflows could also come from profit-taking, portfolio rebalancing, risk reduction, or closing ETF-related trading positions.
This makes the market monitor ETF flows more closely during BTC down legs, as each day of large outflows shows that buying power through the ETF channel has not yet returned strongly enough.
Bitcoin Faces Outflows as Price Momentum Weakens
The withdrawal streak occurred while Bitcoin was correcting sharply from its May peak. On the daily chart, BTC dropped from around $84,600 to around $66,800, equivalent to a decline of over 20%. The price falling simultaneously with ETFs continuously recording outflows makes daily flow data more closely watched, as the market waits to see whether ETF investors will return to buy when BTC drops deeply.

In previous corrections, ETF inflows could be seen as a signal of investors buying the dip. This time, the opposite is happening: BTC weakens while ETF capital leaves the market. This does not prove that outflows are the sole cause of the price drop, but it shows that buying power through the ETF channel has not appeared strongly enough to absorb the selling pressure.
The $66,000-$67,000 zone now becomes the area to watch in the short term. If BTC can hold this zone while outflows slow down, the market may enter a more stable state. Conversely, if the funds continue to lose hundreds of millions of dollars per session, the market may shift its attention to lower support zones.
A Flow Reversal Becomes the Key Signal
The most critical signal in the coming sessions is whether the outflow streak will end with a net inflow session. After 12 sessions of withdrawals, a single day of small inflows is not enough to confirm a trend reversal, but it will show that redemption pressure is starting to cool down.
The market will also monitor capital flows at major funds like IBIT, FBTC, and GBTC. If these funds return to inflows or withdrawal pressures ease, it could be a sign that demand through the ETF channel is recovering. Conversely, if multiple large funds continue to experience withdrawals simultaneously, ETF outflows could continue to put pressure on Bitcoin and make sentiment in the crypto market more cautious, rather than just being an issue isolated to ETF products.
In addition to daily net flows, two indicators to note are total net assets and cumulative net inflow. If both continue to decline, ETFs will remain a weak point in Bitcoin’s market structure. If capital flows stabilize while BTC holds its current support zone, this record withdrawal streak could transition from a strong sell signal to a phase where the market retests institutional demand.
