US spot crypto ETFs moved in opposite directions on October 5. Bitcoin and Solana funds ended the day with more money leaving than arriving. Ethereum funds went the other way and took in net new capital.
XRP products broke even with zero net flow, according to SoSoValue data reported the same day. A spot ETF is a fund you can buy on a normal stock exchange that holds the actual crypto. The flows are the daily scoreboard: inflows mean more investors put money in than pulled out, outflows mean the reverse.
When that scoreboard flips green for one coin and red for another on the same day, it tells you where money is moving this week. The October 5 flip matters because it ran against the week's trend. SoSoValue's weekly figures showed Bitcoin winning the period while Ethereum lost it.
A single day doesn't rewrite that. It does tell you the split isn't locked in place.
The week still belonged to Bitcoin
For the week ending in early October, US spot Bitcoin ETFs collected $241.09 million in net inflows, SoSoValue reported. That was the third straight positive week for the products. The three-week run has pushed cumulative inflows since the funds launched in 2024 to around $57.8 billion.
Bitcoin traded near $85,000 to $86,000 through the period covered, and capital kept choosing it over the alternatives. SoSoValue framed the pattern as a sentiment shift, with Bitcoin's market dominance continuing to build.
Ethereum's red week after a $690 million green one
Spot Ethereum ETFs shed $138.02 million over the same week, per SoSoValue. That erased the good news from the prior week, when Ethereum funds took in $690 million. The swing matters because of where the year stands.
Ethereum ETF inflows for 2026 now sit at approximately $1.5 billion, a fraction of Bitcoin's $57.8 billion cumulative total. One strong week can flip the monthly narrative, as $690 million proved. One weak week can flip the daily one, which October 5 just did in the opposite direction.
Solana's red day inside a green streak
The Solana outflow on October 5 is a one-day number, and its weekly line tells a different story. Solana spot ETFs gained around $2.43 million in weekly net inflows, according to SoSoValue, extending an existing streak. XRP spot ETFs brought in $4.74 million for the week, also extending a streak.
So the altcoin picture is less a flight to safety and more unevenness around a Bitcoin-led trend. Zcash broke from that pattern entirely. Zcash ETFs recorded their first weekly outflow, roughly $94 million, for the period covering late September through early October.
| Fund | Weekly net flow | Streak status |
|---|---|---|
| --- | --- | --- |
| Bitcoin spot ETFs | +$241.09 million | Third straight positive week |
| Ethereum spot ETFs | -$138.02 million | Reversal of prior +$690 million week |
| Solana spot ETFs | +$2.43 million | Inflow streak continues |
| XRP spot ETFs | +$4.74 million | Inflow streak continues |
| Zcash spot ETFs | -$94 million (approx.) | First weekly outflow |
## Where the next signal sits The weekly numbers still favor Bitcoin, and three straight inflow weeks point to steady demand rather than a one-off spike. The research flagged that Ethereum's outflows could pressure its market position if buyers stay away, though the prior $690 million week shows demand can return fast. Continued rotation toward Bitcoin and other established assets could also mean more volatility across the broader crypto market in the near term. Two concrete things resolve this next. First, the following weekly SoSoValue tally: if Ethereum posts a second straight negative week while Bitcoin stays green, the weekly gap hardens into a trend. Second, Bitcoin's price around the $85,000 to $86,000 zone it held through this data. Hold that range with steady inflows and the case for rotation strengthens; a break below it with outflows would flip the scoreboard everyone is watching.
