Bitcoin ETF experiences over $600 million in net outflows in a single day: An in-depth analysis of the capital withdrawal behind the trend

On May 13, 2026, the U.S. cryptocurrency spot ETF market experienced the largest capital outflow in recent times. Bitcoin spot ETFs saw a net outflow of $630.4 million in a single day, Ethereum spot ETFs net outflowed $36.3 million, totaling over $660 million — and not a single ETF recorded a net inflow that day. Is this a purely risk-averse retreat, or a signal of institutional strategy adjustment?

What is the scale of the $630.4 million daily outflow

The single-day net outflow of $630.4 million from Bitcoin ETFs is one of the largest single-day outflows since 2026. According to market data, this is the highest daily net outflow since January 29, 2026, ranking high in historical records. Over the past five trading days, the total net outflow was about $1.25 billion, reducing the total net inflow of Bitcoin spot ETFs since their launch in January 2024 from $59.76 billion to approximately $58.5 billion. From a temporal perspective, this outflow scale is comparable to a few extreme trading days during this ETF cycle. Notably, although the Ethereum ETF’s single-day outflow of $36.3 million is much smaller in absolute terms, it represents the third consecutive day of net outflows, showing a trend of continuous capital reduction.

Which products bore the main outflows

In Bitcoin ETFs, outflows are highly concentrated in leading products. BlackRock’s IBIT had a single-day net outflow of about $285 million, leading all ETFs, but the fund’s total net inflow still reached $65.77 billion. ARK Invest and 21Shares’ ARKB had a net outflow of $177 million that day, and Fidelity’s FBTC net outflow was $133 million, ranking second and third respectively. On the Ethereum ETF side, BlackRock’s ETHA had a single-day net outflow of $21.1 million, and Fidelity’s FETH net outflow was about $14.04 million, also concentrated in top products. It’s worth noting that the net outflow of IBIT, after conversion, is equivalent to a one-time redemption of about 3,580 Bitcoin, and FBTC about 1,680 Bitcoin being redeemed — such a scale of operation is usually not retail behavior but systematic rebalancing by institutional accounts.

What macro factors are driving the capital withdrawal

The timing of the capital outflow overlaps heavily with macro pressures. U.S. April PPI data significantly exceeded expectations, indicating inflation pressures stronger than anticipated. Prior to this, CPI data also rebounded unexpectedly, and inflation concerns continued to suppress the market. The market generally believes that the Federal Reserve will find it increasingly difficult to justify rate cuts this year, and the high yields on U.S. Treasuries continue to weaken risk appetite for risk assets. Under this pressure, Bitcoin’s price has fallen below $80,000, and as of May 14, 2026, BTC was around $79,800. Macro data reinforce institutional expectations of tightening liquidity conditions, prompting some allocators to reduce their exposure to crypto assets. The outflows are more a risk-avoidance response triggered by macro environment changes rather than a fundamental negation of the crypto market itself.

Are institutions panicking or tactically rebalancing

Data on institutional behavior provide richer signals than single-day outflows. Quantitative trading giant Jane Street’s Q1 13F filings show the firm reduced its holdings of IBIT by about 71%, and FBTC by about 60%, while decreasing its position in MicroStrategy (MSTR) by approximately 78%. Notably, during the same period, Jane Street significantly increased its holdings in Ethereum ETFs, nearly doubling ETHA’s position and substantially increasing FETH’s holdings, injecting about $82 million of incremental capital into Ethereum ETFs. This combination of Bitcoin reduction and Ethereum accumulation indicates active internal rebalancing within the crypto sector, rather than a full-scale panic exit. Many research reports suggest that Bitcoin ETF outflows are unlikely to be the start of long-term disposals, but rather a result of portfolio rebalancing.

What are the synchronized changes in market sentiment and capital flows

Alongside ETF capital outflows, market sentiment has also noticeably cooled. Recently, the Crypto Fear & Greed Index has remained around 38, in the fear zone, down from the previous neutral zone at 47. Meanwhile, U.S. market purchasing power is significantly subdued, with Coinbase’s premium index remaining negative for several days, indicating weak spot demand among U.S. investors. Bitcoin’s market share has rebounded from a low of about 55% to around 58.5%, showing that, despite overall capital pressure, some funds still concentrate on Bitcoin rather than shifting to altcoins. The relationship between ETF capital flows and price is also changing. Correlation studies show that Bitcoin’s daily returns and ETF daily net inflows’ 90-day rolling Pearson correlation coefficient has fallen to about 0.16, statistically close to zero, indicating that daily ETF capital flow directions have become much less predictive of price movements.

From single-day peaks to multi-day trends: what shifts are occurring in capital flows

While large daily outflows are noteworthy, the deeper change in institutional demand can only be revealed through cumulative trends over weeks or months. Before this outflow, in April 2026, Bitcoin spot ETFs still recorded about $2.44 billion in net inflows, with total net inflow for the year exceeding $59 billion at one point. Looking at a longer timeframe, crypto investment products saw a net inflow of $857.9 million in the week ending May 10, 2026, with Bitcoin products receiving $706.1 million, marking the sixth consecutive week of positive capital flow. This indicates that the overall institutional allocation trend to crypto assets has not reversed. The large outflow on May 13 is more likely a temporary peak rather than a directional trend reversal. Whether Ethereum ETFs’ three consecutive days of net outflows evolve into a more persistent withdrawal pattern, or Bitcoin ETF outflows are later offset by capital inflows, requires ongoing monitoring.

Summary

The combined capital withdrawal of over $660 million from Bitcoin and Ethereum spot ETFs on May 13 reflects institutional risk-avoidance in response to U.S. inflation data exceeding expectations. Leading products like BlackRock’s IBIT, ARKB, and Fidelity’s FBTC contributed most to the outflows, with Ethereum’s ETHA also among the top. Quantitative firm Jane Street’s Q1 reduction in holdings shows a strategy of Bitcoin trimming and Ethereum increasing, indicating internal sector rebalancing rather than a full exit. The Crypto Fear & Greed Index remains in the fear zone, but crypto investment products have recorded six consecutive weeks of net inflows, with the annual net inflow still high. The significance of the peak daily outflow needs to be tested over subsequent weeks or months — if capital quickly flows back, this outflow may merely be a tactical rebalancing peak.

FAQ

Q: Where does the $630.4 million net outflow stand historically?

A: This outflow is one of the largest single-day outflows since 2026 and is a relatively rare capital peak since November 2025. Over the past five trading days, the total outflow was about $1.25 billion, but the annual net inflow remains high.

Q: Why is Ethereum ETF outflow much smaller than Bitcoin ETF?

A: The assets under management for Ethereum spot ETFs are about $13.19 billion, far less than Bitcoin ETFs’ $105 billion, so the absolute daily outflow is naturally smaller. However, in proportional terms, both reflect similar withdrawal tendencies.

Q: Does Jane Street’s significant reduction in Bitcoin ETF holdings imply institutional bearishness on Bitcoin?

A: While Jane Street sharply cut its IBIT and FBTC holdings in Q1, it also significantly increased its Ethereum ETF positions, nearly doubling ETHA and adding substantially to FETH. This more reflects internal rebalancing and strategic adjustments within the crypto sector rather than a fundamental negative view on Bitcoin assets.

Q: Does this capital outflow indicate that demand for crypto ETFs has peaked?

A: Determining a demand peak requires observing continuous trends over weeks or months. A single peak day has limited predictive value. Despite the recent six-week streak of net inflows, the long-term trend of institutional crypto allocation needs ongoing data to confirm.

Q: Will the outflow immediately negatively impact spot prices?

A: Correlation studies show that the correlation between ETF daily net flows and Bitcoin’s daily returns has fallen to about 0.16, indicating a weak predictive capacity of daily flow directions on prices. However, sustained large outflows may still reflect marginal shifts in institutional demand.
