Bitcoin ETFs Just Set Their Worst 30-Day Outflow on Record

U.S. spot Bitcoin ETFs just posted their worst 30-day stretch since they launched. Galaxy Research clocked a record $6.35 billion in net outflows over the past month.

Galaxy ranked it #1 across all 582 rolling 30-day windows it tracks. That is every monthly window since these funds went live, and this one was the ugliest.

Bitcoin, the largest crypto asset by market cap, fell about 17% over the same month. It was trading near $64,260 in BeInCrypto’s snapshot.

The ETF bid that once helped push Bitcoin higher is now pulling the other way.

BeInCrypto detailed the record 30-day Bitcoin ETF outflow and the signs that the selling pace has cooled. U.S. spot Bitcoin ETFs posted a $6.35 billion net outflow over the last 30 days, the heaviest rolling window Galaxy Research has tracked since the products launched in January 2024.

Galaxy ranked the stretch first across all 582 rolling 30-day windows it follows, which makes this more than a rough patch in one fund. The outflow period arrived while Bitcoin was down about 17% over the past month and trading near the mid-$64,000 area in BeInCrypto’s market snapshot.

That matters because ETF flows were a central support for Bitcoin during earlier rallies, and a sustained redemption window can turn the same channel into a source of supply pressure. The story also keeps the pressure in perspective: BlackRock IBIT still showed $62.1 billion of net inflows since launch, while GBTC had lost $27 billion.

Across the full complex, Farside data cited by BeInCrypto still showed $53.4 billion in total net inflows, so the record 30-day bleed did not erase the entire ETF adoption story. The more interesting twist is that weekly outflows dropped 87%, from $1.72 billion in the week ending June 5 to about $226 million last week.

Farside Investors tracks the daily fund-by-fund Bitcoin ETF flow data behind the headline numbers. The Farside table separates daily flows by individual fund, including IBIT, FBTC, BITB, ARKB, GBTC, and the total complex flow.

That fund-level view is important because ETF demand is not a single pool of money moving in one direction for one reason. A daily total can hide very different behavior underneath it, including old GBTC redemptions, newer IBIT demand, profit-taking, portfolio rebalancing, and risk-off withdrawals.

For a 30-day record outflow story, the table helps readers understand the difference between one dramatic daily print and a rolling window built from many trading sessions. It also helps explain why the market can see record cumulative outflows while some funds still carry massive net inflows from launch.

That is the cleaner read for Bitcoin: ETF demand has turned negative over the current window, but the product category remains structurally large. The pressure therefore sits in the marginal flow, not in the existence of the ETF market itself.

CoinDesk showed how June ETF pressure had already been building before the latest 30-day record. CoinDesk reported earlier this month that U.S. spot Bitcoin ETFs ended a 13-session outflow streak totaling roughly $4.4 billion.

That earlier run matters because it shows the current 30-day record did not appear from one isolated redemption day. ETF pressure had already been accumulating through June as investors reduced exposure during a weaker Bitcoin tape.

The same story also showed how quickly a daily flow reading can flip, since the streak ended with a small net inflow. That is useful context because the market should not treat one day, or even one week, as the whole demand picture.

The 30-day window is serious because it smooths the day-to-day noise, while the recent weekly cooldown shows the selling intensity may be changing. Both points can be true at once: ETF flows are the worst they have been on a rolling 30-day basis, and the most recent weekly pace is less severe.
