US spot crypto ETFs attracted roughly $64.8 million in combined inflows on Monday, a decline of about 80% from Friday, after the four major fund categories pulled in more than $3.3 billion over the previous week, according to SoSoValue data.

Spot Bitcoin ETFs led Monday's totals with $31.07 million, followed by Ether ETFs at $17.1 million, Solana funds at $12.7 million and XRP products at $3.96 million. Zcash ETFs, which added about $35 million last week, posted an $8.1 million outflow on Monday.

The sharp daily step-down follows Friday's combined intake of roughly $330.8 million across the four categories. On that day, Bitcoin funds drew $134.47 million, Ether funds took in $86.95 million, Solana products attracted $86.7 million and XRP ETFs added $22.65 million.

How strong was the prior week?

The weekly picture remains the dominant force behind the flows. Bitcoin ETFs alone attracted $2.39 billion last week, with Ether funds at $690 million, Solana at $188 million and XRP at $75.6 million, per SoSoValue data.

Monday's $64.8 million total represents normalization after that surge rather than a reversal. Every one of the four categories stayed in positive territory, and each extended its net inflow streak by another trading session.

Which funds drove Monday's flows?

The composition of Monday's inflows was concentrated in a handful of issuers:

• Bitcoin ETFs extended their net inflow streak to eight consecutive sessions, accumulating about $3 billion over that period, including a 2026 high of nearly $1 billion on Sept. 21.
• Ether ETFs logged a seventh straight positive session. Farside data shows BlackRock's iShares Ethereum Trust accounted for $15.4 million of the $17.1 million category total, with 21Shares' TETH adding $1.7 million.
• Solana ETFs stretched their streak to seven sessions, with Bitwise's BSOL responsible for most of the day's inflows.
• XRP ETFs marked a fifth consecutive positive session, with Canary Capital's XRPC attracting the entire $3.96 million category inflow.

What does the cooldown signal?

For issuers and market structure watchers, the data point to demand that is cooling in magnitude but persistent in direction. The continuation of all four streaks — five to eight sessions depending on the asset — suggests allocation flows into regulated crypto vehicles have not reversed, even as the pace falls back from last week's elevated volumes.

Issuer concentration also matters operationally. BlackRock's dominance of Ether inflows and Canary Capital's full capture of XRP flows indicate that liquidity is consolidating around a small number of products rather than distributing across the category, a pattern that shapes fee competition and secondary-market depth.

Whether the streaks hold will depend on whether last week's $3.3 billion run proves a sustained repricing of crypto exposure through ETF wrappers or a one-off allocation burst. The next several trading sessions of flow data from SoSoValue and Farside should settle that question.
