U.S. spot Bitcoin ETFs extended a selloff streak into a new record, according to NewsData.io.
In late May and early June 2026, the funds ran 13 straight days of net outflows. The total, per NewsData.io, was $4.4 billion. That makes the run the longest since the ETFs launched.
What drove the outflow run
NewsData.io points to macro headwinds and sector rotation as the main backdrop. Those forces matter because spot Bitcoin ETFs do not trade like traditional “set and forget” vehicles. Their flows react to risk appetite, and they can lose momentum when institutions rotate into other areas.
Within the selling, BlackRock’s IBIT took the lead in driving outflows, NewsData.io reports. In practice, “led the selling” means investors were pulling net capital through the most liquid and widely tracked option.
Are institutions done? Not yet
The same NewsData.io report adds a more conditional detail. It says recent sessions show flows turning positive and outflows slowing sharply.
That matters because a streak can overstate direction. A long run of outflows signals pressure, but a sudden shift toward positive flows suggests at least some of that pressure eased. Still, the report frames the episode as a test of institutional conviction, not as proof institutions quit the trade.
The bigger ledger still favors inflows
Even with the record outflow streak, NewsData.io says cumulative inflows remain above $54 billion.
So the episode looks less like a structural reversal and more like a short-term pullback that temporarily fought the longer accumulation trend. That distinction is the key practical takeaway for readers tracking ETF flows as a real-time signal of institutional appetite.
| Metric | What NewsData.io says | Why it matters |
|---|---|---|
| Outflow streak length | 13 days | Longest since launch, shows persistent pressure |
| Total outflows during streak | $4.4 billion | Scale of the pullback |
| Primary fund with selling pressure | BlackRock IBIT | Indicates where net selling concentrated |
| Recent sessions | Flows turning positive, outflows slowing | Suggests pressure eased, not necessarily a full exit |
| Cumulative inflows | Above $54 billion | Long-run demand still outweighs the recent dip |
What to watch next
NewsData.io’s framing boils down to a simple question. When flows flip back positive, does it stick, or do macro headwinds and rotation win again?
For now, the numbers show an institutional pullback significant enough to set a record, alongside signs that the sell pressure may be losing steam. That tension is exactly what ETF flow watchers should track day by day.
