Bitcoin ETFs Break Their Outflow Record as $4.3 Billion Exits

Spot Bitcoin exchange-traded funds (ETFs) shed $4.33 billion across 13 consecutive trading sessions from May 15 to June 3, the longest net-outflow streak since the category launched in January 2024, per Galaxy Research’s flow tracking data. The funds returned 59,351 BTC over that span, erasing April’s $1.97 billion in inflows, the strongest monthly total the category had posted in 2026.

Year-to-date flows for the broad category turned negative over those 13 sessions, undoing a recovery that had taken months to build. Bloomberg senior ETF analyst Eric Balchunas noted that BlackRock’s iShares Bitcoin Trust (IBIT) and a handful of peers still held positive flows for the year, and that cumulative lifetime net inflows for the group sit near $55 billion, less than $10 billion below the category’s high-water mark.

Records That Span Every Window

Galaxy Research tracked the outflow pressure across multiple trailing windows, and each one set a fresh record. The 7-day window closed at 39,338 BTC, the highest for any rolling 7-day stretch since these products began trading. The 10-day reading hit 42,941 BTC, also a record. The 20-day trailing total reached $5.42 billion and 73,080 BTC, the heaviest reading in both measures the products have ever produced.

Across all U.S. spot Bitcoin ETFs, total net assets dropped from $104.29 billion on May 15 to $82.83 billion by June 3, a $21.46 billion decline that combines direct redemptions with a price fall, per SoSoValue’s U.S. spot Bitcoin ETF data and Farside Investors. Bitcoin traded near $80,000 on May 15 and settled at $62,644 on June 3, down roughly 22% over those same sessions, per CoinPaprika.

• $4.33 billion / 59,351 BTC shed during the 13-session streak
• $5.42 billion / 73,080 BTC in the 20-day trailing window, the heaviest on record
• 39,338 BTC in the 7-day window, a record
• 42,941 BTC in the 10-day window, a record
• Total ETF assets: $104.29 billion (May 15) to $82.83 billion (June 3)

Through 10 sessions, the run had already eclipsed a record Bitcoin ETF outflow streak at $2.97 billion that had stood as the longest in the category’s history. The 13-session final count reset every benchmark that run had established.

IBIT Carries 86% of a Single Day

On June 3, IBIT accounted for $342.3 million of the day’s $396.6 million in total Bitcoin ETF outflows, or 86% of the category’s daily redemptions, per Farside Investors and SoSoValue. Two sessions earlier, on June 1, the fund logged $440.3 million in outflows out of $483.8 million for the category.

IBIT’s weight in the outflow tally reflects its weight in the market. The fund holds roughly 660,000 to 670,000 BTC, and its asset base of $44 billion to $46 billion makes it the most liquid vehicle in the group by a wide margin. On May 26, a $1.26 billion dark-pool block sale tied to the fund registered as the single largest redemption event in its history since launch, per Tokenist. On-chain data confirmed the transfer of approximately 6,005 BTC from IBIT-linked custody wallets to Coinbase Prime alongside the redemption, per the same analysis.

Redemption pressure wasn’t limited to BlackRock. Fidelity’s FBTC lost $37.3 million on June 1, while Ark and 21Shares’ ARKB shed $12.3 million. Morgan Stanley’s MSBT drew $6.1 million in inflows that session, the lone exception among the named funds. Grayscale’s GBTC, which carries a substantially higher annual fee than its peers, drew an outsized share of redemptions relative to its market weight throughout the streak, a pattern that has recurred through every outflow episode since it converted from a closed-end trust structure in January 2024.

First-quarter 2026 13F filings had shown the broadest institutional ownership base yet for Bitcoin ETFs, with pension funds, endowments, and sovereign-wealth-adjacent vehicles appearing among holders for the first time, per data compiled by Coinfomania. Unlike dedicated crypto funds, pension funds and endowments operate under compliance mandates and portfolio-allocation limits that can become forced-selling triggers during sustained price declines. The June selling raised early questions about how sticky that new cohort would prove.

The Rate Reckoning

The streak opened on May 15, a session the Investing.com trading desk described as Bitcoin “pivoting around the $80,000 psychological line” while Treasury yields were printing multi-decade highs. The rate-expectations landscape had shifted sharply in the months prior: energy prices linked to ongoing geopolitical tensions had kept inflation above the Federal Reserve’s target, eroding the case for cuts that markets had priced in at the start of 2026.

By late May, the CME FedWatch Tool showed a greater-than-60% probability that the Federal Reserve’s next move under Chairman Kevin Warsh, who succeeded Jerome Powell, would be a rate hike, with a 25-basis-point increase priced as the most likely outcome by March 2027. The 10-year Treasury yield broke above 4.55% for the first time since May 2025, and the 30-year briefly crossed 5%. Barclays, in removing its 2026 rate-cut forecast, cited persistently high energy prices tied to geopolitical tensions as the driver keeping inflation elevated. JPMorgan made similar revisions.

For institutional allocators running carry-trade-adjacent positions in Bitcoin ETFs, the arithmetic changed. A 30-year Treasury at 5% is a near-risk-free return on its own terms. Many positions built in the $52,000-to-$58,000 range during the first quarter of 2026 sat on substantial unrealized gains when the rate shock arrived in mid-May.

Analysts cited by Coinfomania characterized the selling as rational profit-taking that a changing macro backdrop accelerated, with outflow concentration in higher-fee and larger vehicles pointing to deliberate de-risking. Short-dated Treasuries above 4% provide institutional capital a liquid alternative to Bitcoin positions, a meaningful change from the zero-rate environment that powered the category’s first year of inflows.

Strategy’s 32-Coin Signal

On June 1, Strategy Inc., the largest corporate Bitcoin holder, disclosed in a Form 8-K filed with the Securities and Exchange Commission that it had sold 32 BTC between May 26 and May 31 at an average price of roughly $77,135 per coin, generating approximately $2.5 million to fund distributions on STRC, its high-yielding perpetual preferred stock known as Stretch.

The sale was the company’s first since December 2022, when it disposed of 704 BTC for a tax-loss harvest before buying back more two days later. With 843,706 BTC on its balance sheet as of May 31, the 32 coins were roughly 0.004% of its holdings. TD Cowen analyst Lance Vitanza called reports of a meaningful position reduction “overblown,” characterizing the transaction as a tactical dividend move with no bearing on the company’s accumulation stance, per CoinDesk.

Markets didn’t read it that way first. Its shares fell more than 5% in premarket trade on June 1. Bitcoin slipped below $72,000 on the announcement, down roughly 2.5% over the prior 24 hours.

The disclosure also resolved a $79 million Polymarket prediction market on whether the company had sold Bitcoin by May 31. One trader had bet YES when the implied probability sat near 11%, and the June 1 filing delivered an estimated $200,000 payout, per CoinDesk.

Ethereum and the Altcoin Split

Bitcoin ETFs weren’t alone in the selloff. Ethereum spot ETFs posted 17 straight outflow days through June 3, their longest consecutive streak on record. BlackRock’s ETHA shed roughly $35 million on June 1; Fidelity’s FETH logged approximately $9.5 million in redemptions the same session, per Bitcoin.com. Total Ethereum ETF assets tracked by SoSoValue declined in parallel, though the absolute dollar figures are smaller given the Ethereum funds’ more limited asset base.

Newer products followed a different path. Hyperliquid (HYPE) spot ETF funds drew continuous inflows since their mid-May debut. XRP products recorded scattered positive sessions alongside flat days. The BNB ETF posted just one positive session since its launch.

Across all five categories, the split is consistent: capital has left the established crypto ETF products at record pace while newer, smaller funds face their own early test of demand durability. The stablecoin market reached a total value above $322 billion through the same period, per Intellectia AI, suggesting some capital rotating out of directional crypto positions held in dollar-denominated form within the digital asset ecosystem.

Is the Holder Base As Strong As the Numbers Suggest?

When the scale of the streak became clear, Bloomberg senior ETF analyst Eric Balchunas drew a comparison to the SPDR Gold Shares ETF (GLD), which launched in 2004 and eventually lost roughly 40% of its assets over a difficult stretch before gold’s price recovered and the fund rebuilt many times over. His assessment, posted on X:

Not bad at all for this type of drawdown and negative sentiment. Gold went down like this a few years after GLD debuted and 40% of the assets left, much stronger holders here so far. But yeah, to quote Henry Hill, this is the bad times.

Balchunas posted that on X as year-to-date flows had already gone negative for the category, noting a handful of funds had held positive for the year.

Measured against the category’s history, the $4.33 billion that exited during the streak is less than 8% of cumulative lifetime net inflows of $55 billion. The 59,351 BTC that left across all Bitcoin ETFs during those 13 sessions equals roughly 9% of what the category’s largest fund holds by itself, one data point on how much of the overall institutional base stayed through the selling.

GLD’s recovery unfolded over years in which the Federal Reserve eventually cut rates toward zero following the 2008 credit crisis, generating the liquidity environment that helped gold rebuild its asset base. Bitcoin ETFs are navigating a setup where CME FedWatch data shows markets pricing a rate hike as the most likely next Fed move, and Barclays has pushed its forecast for any policy easing to March 2027.

Cumulative lifetime net inflows sit near $55 billion, less than $10 billion below the high-water mark the category held before May 15.
