Institutional money is voting with its feet โ and right now, it is walking straight into Bitcoin and away from Ether. The latest ETF flow data makes the preference unmistakable: US spot Bitcoin funds notched a third consecutive week of net inflows while Ether funds swung sharply back into the red, reinforcing a widening gap in institutional conviction between the two largest crypto assets.
Bitcoin ETFs Clock Third Straight Week of Inflows
US spot Bitcoin exchange-traded funds pulled in $241.1 million in net inflows last week, extending a winning streak that now spans three consecutive weeks, according to SoSoValue data. The haul pushed cumulative net inflows for the funds to $57.8 billion since launch โ a staggering figure that underscores just how deeply embedded Bitcoin exposure has become within institutional portfolios.
The momentum is worth contextualising. The two preceding weeks saw inflows of $2.4 billion and $6.2 million respectively, meaning last week's $241.1 million sits in a broader pattern of consistent, if uneven, institutional accumulation. Year-to-date net inflows for Bitcoin ETFs now stand at approximately $1.2 billion.
On the price side, Bitcoin was trading at approximately $86,200 at the time of reporting, up 3.7% over the prior seven days, according to CoinGecko. The confluence of rising prices and rising fund inflows points to a market where institutional buyers are not yet deterred by elevated levels โ they are, if anything, leaning in.
Bitcoin saw both rising prices and fresh inflows. Ether, by comparison, saw outflows during a week when its price also went up.

The contrast with Ether could scarcely be sharper. Ether ETFs recorded $138 million in net outflows last week โ a dramatic reversal from the $690 million in net inflows the funds had attracted the week before, per SoSoValue data. That is a swing of more than $828 million in a single week, and it raises uncomfortable questions about the durability of institutional enthusiasm for ETH-wrapped products.
Ether itself was not the culprit, at least not on a price basis. The asset traded at approximately $2,727, up 3% over the same seven-day period, according to CoinGecko. In other words, Ether ETFs bled capital during a week when Ether's price was rising โ a signal that the outflows reflect a deliberate repositioning rather than panic selling triggered by price action.
Year-to-date net inflows for Ether ETFs remain positive at approximately $1.5 billion, per SoSoValue. But the latest week's reversal suggests that patience for ETH exposure, at least via the ETF wrapper, is thinner than it appeared just seven days ago. Traders who rotated in during Ether's strong prior week appear to have rotated right back out.
Zcash Posts Its First Weekly Outflow Ever; Solana and XRP Hold Steady
The turbulence extended beyond the Bitcoin-Ether divide. Zcash funds posted their first weekly outflow on record, shedding approximately $94 million over the week, according to SoSoValue data. That figure ends what had been a perfect inflow record for the Zcash products since their launch โ a notable milestone, though one that likely reflects idiosyncratic positioning rather than a broader collapse in privacy-coin sentiment.
Meanwhile, smaller altcoin ETF categories continued to grind quietly higher. Solana ETFs added $2.4 million for the week, while XRP ETFs brought in $4.7 million โ both extending their respective inflow streaks. The totals are modest relative to the Bitcoin and Ether figures, but the consistency matters: both products have now built multi-week runs of positive flows, a sign that retail and institutional interest in diversified crypto exposure has not evaporated entirely.
Crypto market sentiment did cool slightly over the period. Alternative.me's Crypto Fear & Greed Index held in "Greed" territory at a reading of 70, down from a prior reading of 74. The index remains well above the neutral midpoint, suggesting that the broader market has not lost its risk appetite โ but the slight softening may reflect some caution creeping in as prices hold at elevated levels.
The Institutional Signal Is Clear: BTC Over ETH, For Now
Three straight weeks of Bitcoin ETF inflows, set against a sharp single-week reversal in Ether fund flows, tells a story that institutional allocators appear to be writing in real time: when forced to choose between BTC and ETH exposure, the money is choosing Bitcoin. The $241.1 million weekly inflow figure is not a blowout number โ Bitcoin has seen weeks of $2.4 billion โ but its consistency in the context of Ether's volatility is precisely the point.
The "Uptober" narrative that has historically buoyed crypto markets in October appears to be serving Bitcoin more than Ether this cycle. With cumulative Bitcoin ETF inflows now sitting at $57.8 billion and Ether funds swinging by hundreds of millions week to week, the divergence in institutional confidence is difficult to ignore. Unless Ether ETF flows stabilise and reverse in the coming weeks, the gap in institutional preference between the two assets risks becoming a self-reinforcing trend โ one that Bitcoin bulls will be happy to watch widen.
For now, the data is unambiguous: in the ETF era, Bitcoin is the institutional trade. Ether is still searching for its footing.
