Bitcoin exchange-traded funds bled $2.8 billion over nine consecutive trading days, the longest and largest outflow streak on record. The selloff, which ended Wednesday, coincides with a sharp pullback in accumulation by large holders — a double blow for a market already struggling for momentum.
The record run
The nine-day outflow marathon began on May 18 and ran through May 27, according to data tracked by GFdaily. Each day saw net redemptions, with the total $2.8 billion figure surpassing any previous stretch of withdrawals since the first U.S. spot Bitcoin ETFs launched in January 2024. The previous record was a seven-day outflow of roughly $1.6 billion set last October.
The streak broke on Thursday as flows turned flat, but the damage is done: cumulative outflows for May now top $3.7 billion, putting the month on track to be the worst for the ETF category since its inception.
Whale activity dries up
Alongside the ETF exodus, large Bitcoin holders — often called whales — have pulled back sharply. Data from on-chain trackers shows that addresses holding at least 1,000 BTC have reduced their net accumulation over the past two weeks. The trend is a stark reversal from the first quarter, when whales were steadily adding to positions.
The combination matters. Whales are a key source of market liquidity and confidence. When they stop buying, and institutional money flows out of ETFs at the same time, it creates a feedback loop that makes it harder for prices to find support.
No clear catalyst
The facts don't point to a single trigger for the outflow streak. No major regulatory action, exchange hack, or earnings miss coincided with the start of the withdrawals. It's possible the selling reflects a broader rotation out of risk assets — equities have been choppy this month — or simply profit-taking after Bitcoin's run to $95,000 in April.
What's clear is that the ETF flows and whale behavior are moving in the same direction, and that's rarely a good sign for near-term demand. The nine-day streak is now in the books, but the question hanging over the market is whether the pause that followed Thursday's flat flows is a breather or the start of a new leg lower.
