US spot Bitcoin exchange-traded funds recorded $102.7 million in net inflows on the first trading day of October, reversing Wednesday's $148.7 million in net outflows, according to data from SoSoValue. The positive session followed the funds' strongest quarter to date, with $6.34 billion in third-quarter net inflows.

The combined net assets of the US spot Bitcoin ETF complex rose to $109.3 billion, while cumulative net inflows since launch reached $57.6 billion. September alone contributed $2.65 billion to the quarterly total, and Bitcoin gained 42.71% over the three-month period.

Ether funds told a different story. US spot Ether ETFs posted $55.4 million in net outflows on Thursday, extending a redemption streak to three consecutive trading days and roughly $118 million in cumulative losses over that window. The divergence marks a persistent imbalance between the two largest crypto ETF categories: Bitcoin products continue to absorb assets while Ether products bleed, despite trading in the same macro environment.

Solana ETFs also faced pressure, recording approximately $6 million in net outflows on Thursday and extending their own outflow streak to two sessions. XRP funds were the outlier among altcoin products, attracting $4 million in net inflows.

Bitcoin traded at about $85,900 at the time of publication, up 2.1% over the past 24 hours, according to CoinGecko. Alternative.me's Crypto Fear & Greed Index slipped to 72 from 74 a day earlier, remaining in "Greed" territory — a modest cooling that has not yet translated into reduced Bitcoin ETF demand.

The inflow figures arrive as market participants track whether October, historically a strong month for crypto asset performance among retail traders who label it "Uptober," can sustain the institutional momentum built during the third quarter. The $6.34 billion quarterly intake represents the benchmark for the current period, and Thursday's $102.7 million daily pace would need to accelerate materially to match it.

The operational picture for issuers remains favorable on the Bitcoin side. Sustained net creations support primary-market activity and keep authorized participants engaged, while the Ether outflow streak pressures issuers of those products to defend market share with fee compression and new product structures. If Ether ETF redemptions extend through another week, the three-day $118 million outflow could become a quarterly-scale drag comparable to the inflows Bitcoin funds are capturing.

The next test comes with the release of September employment data and further movement in US bond yields, which dropped from new 24-year highs this week — a macro shift that has coincided with Bitcoin's attempt to hold its local uptrend. Traders will watch whether Bitcoin ETF inflows hold above the $100 million daily threshold in the coming sessions, a level that would confirm the October opening was more than a single-day reversal of Wednesday's outflows.
