Crypto exchange-traded funds (ETFs) — investment products that give investors exposure to Bitcoin or Ethereum through regular brokerage accounts — recorded combined net outflows of $1.22 billion over a single week, and not one of the week's trading sessions ended in positive territory. Every single day closed in the red.

A “green session” refers to a trading day on which more money flows into a fund than leaves it, and the week in question produced zero such sessions. Investors pulled capital out every single day, adding up to one of the more consistent stretches of selling seen in the crypto ETF market. Net-flow figures like these are among the most closely watched numbers in the sector, since they show whether mainstream investors trading through ordinary brokerage accounts are adding to or trimming their crypto exposure.

Bitcoin ETFs Account for $686.7 Million of the Weekly Outflow

Bitcoin ETFs — funds that hold Bitcoin on behalf of investors — saw $686.7 million leave over the week. That represents just over half of the combined $1.22 billion total. When money leaves an ETF, it means investors are choosing to sell their shares rather than hold them.

The outflows fit within a much broader pattern of volatile ETF flows. Earlier periods saw the opposite extreme: Bitcoin and gold ETFs together drew $7 billion across five U.S. trading sessions, a reminder of how quickly sentiment toward these products can swing from one extreme to the other. There have also been individual sessions in which U.S. spot Bitcoin ETFs recorded their biggest single-day inflow in nearly two years, which makes a full week with zero green days stand out even more sharply by comparison.

Ethereum ETFs Add $504.1 Million to the Weekly Loss

Ethereum ETFs contributed the remaining $504.1 million in outflows. Together, the Bitcoin and Ethereum figures account for the full reported $1.22 billion weekly loss. Ethereum's share — roughly 41% of the total — is notable given that Ethereum ETFs are newer products with a smaller overall asset base than their Bitcoin counterparts. U.S. spot Bitcoin ETFs began trading in January 2024, with spot Ethereum ETFs following that July, so the Ethereum products have had less time to accumulate assets.

The Ethereum outflow also echoes a recent trend. In a prior week, Bitcoin ETF outflows of $480 million coincided with Ethereum outflows hitting a nine-month high, suggesting the two assets have moved in sync when turns negative. By contrast, Ethereum ETFs took in $226 million in a single day during a more optimistic stretch earlier this year.

It is worth noting that these figures are drawn from a single reported source and had not been independently verified by multiple data providers at the time of writing.

What an All-Red Week Signals for Crypto ETF Sentiment

An unbroken string of outflow sessions is unusual. Most weeks contain at least one day on which buyers slightly outnumber sellers. A week with no green sessions at all suggests sustained, consistent selling pressure rather than a bad day followed by a recovery.

That said, fund flows do not directly tell us anything about underlying coin prices. Outflows mean investors are selling their ETF shares, but that selling pressure is absorbed by market makers and does not always translate one-for-one into spot price declines for the underlying assets.

With net-flow data published at the close of every trading session, the disclosures due in the sessions ahead will show directly whether this streak of red days extended or broke.

Not every crypto ETF saw money leave during this period, however. XRP ETFs maintained a 13-week inflow streak even as Bitcoin, Ethereum, and Solana products lost a combined $1.25 billion, pointing to selective rather than broad-based selling across the crypto ETF landscape.
