CT just got a fresh mood check, and it is not exactly bullish. US spot Bitcoin$60,174.13 ETFs just logged their longest withdrawal streak since launch, with investors pulling a cumulative $2.84 billion over nine straight trading sessions through May 29. [1]

That makes this the longest outflow run for the products since they debuted in 2024. The key nuance: it is a record by duration, not by dollars. A similar selloff in February 2025 lasted eight sessions but drained about $3.2 billion, so this stretch is slower, not necessarily more violent. [2]

The streak in numbers

Fresh data from Farside Investors showed another $223 million in net outflows on Thursday, extending the streak to nine days. For a product set that spent much of its early life marketed as the cleanest institutional on-ramp to Bitcoin$60,174.13, that is a loud signal. [3]

The simplest read is that demand through the ETF wrapper has cooled. That does not automatically mean institutions are done with BTC, but it does suggest fewer buyers want exposure in this format right now. For traders watching sentiment, this is one of those "follow the flows" moments.

BlackRock's IBIT carried most of the pain

BlackRock's iShares Bitcoin Trust, better known on CT as IBIT, did most of the heavy lifting on the way down. The fund accounted for roughly $2.04 billion of the nine-day total between May 15 and May 29.

One session stood out: May 27 saw about $527.8 million leave IBIT, its second-largest daily outflow on record. That was just shy of the fund's all-time biggest single-day withdrawal, around $528.3 million, set on Jan. 30, 2025. [4]

That matters because IBIT is not some side quest ETF. It is the category heavyweight. As of the latest available market close, the fund held about 792,000 BTC, around 62% of all Bitcoin$60,174.13 held across US spot Bitcoin ETFs, according to Wallet Pilot. When IBIT leaks, the whole room notices.

What the outflows may be saying

ETF flows are not a perfect sentiment poll, but they are one of the cleaner institutional tells available in public. A nine-day bleed like this can reflect several things at once: de-risking after a strong run, portfolio rebalancing, macro nerves, or a shift toward other crypto exposures. [5]
The timing also lands as some large public Bitcoin holders face renewed scrutiny from investors. At the same time, newer products tied to alternative crypto narratives have shown they can still attract attention. That does not mean capital is abandoning Bitcoin altogether, but it does hint that the market's appetite is getting more selective.

Record streak, mixed message

There is also a difference between "longest" and "worst." The current run beats the prior duration record from February 2025, but not the total dollars lost in that episode. That distinction matters if you are trying to separate panic selling from steady institutional cooling.

A drawn-out outflow pattern can be more revealing than a single ugly day. It suggests this is not just one headline shock or one fund rebalancing. It looks more like persistent hesitation.

Why this matters for Bitcoin's next move

Spot ETFs changed Bitcoin market structure by giving traditional investors a regulated, familiar wrapper for exposure. When flows were positive, they helped reinforce the idea that Wall Street demand could support price during risk-off stretches. When flows reverse for this long, that narrative gets stress-tested.

For Bitcoin itself, the immediate issue is less about optics and more about whether organic spot demand can offset ETF selling. If ETF redemptions keep running while broader crypto risk appetite stays uneven, price support may need to come from a different buyer base.

The Bottom Line

This is a record streak by length, with $2.84 billion pulled over nine sessions, and BlackRock's IBIT leading the exits. The setup does not prove a structural breakdown in Bitcoin demand, but it does show the ETF bid is no longer automatic.

The practical takeaway: watch whether this streak ends with a sharp reversal or just fades into more slow bleeding. A clean inflow bounce would suggest institutions were trimming risk, not leaving the trade. More outflows would make that "Wall Street is always buying the dip" narrative look a lot less sturdy.
