Bitcoin spot ETF regained a net inflow of US$101.1 million, and Ethereum and Solana funds continued to flow out

On September 2, 2026, the U.S. spot Bitcoin exchange-traded funds (ETFs) recorded a net inflow of US$101.1 million, reversing the net outflow of US$236.5 million in the previous trading day. At the same time, funds from Ethereum and Solana-related funds continue to drain. Against the backdrop of the weak performance of altcoin funds that day, the strong rebound of Bitcoin ETFs was particularly eye-catching, with BlackRock's IBIT playing a key role.

This one-day trend once again refocuses the market's focus on Bitcoin, highlighting its status as the preferred destination for institutional funds. This article will compare the momentum of Bitcoin ETFs with the outflow pressure faced by Ethereum and Solana products, and sort out the key points investors should pay attention to as this differentiation develops.

Quick overview of core points

• On September 2, the spot Bitcoin ETF returned to a net inflow of US$101.1 million after experiencing a net outflow of US$236.5 million on September 1.
• On the same day, the Ethereum ETF had a net outflow of US$48.2 million and the Solana ETF had a net outflow of US$6.1 million.
• Bitcoin prices were US$77,824, up 1.86% during the day, showing strong momentum in the spot market, while fund funds flowed among different assets.

BlackRock IBIT led the rebound of Bitcoin ETF

This rebound was mainly concentrated on the top products. On September 2, BlackRock's IBIT attracted US$115.4 million in new funding, enough to offset the US$56.2 million outflow from Grayscale's GBTC on the same day. The net result is positive, turning the entire sector green (net inflow). Currently, the cumulative net inflow of U.S. spot Bitcoin ETFs tracked is close to US$54.781 billion.

The one-day recovery replicated the pattern of a rebound led by BlackRock in previous cycles, when the fund recorded record inflows. Despite volatile capital flows, spot prices remained firm. At the time of data collection, Bitcoin had risen 1.86% to $77,824 in the past 24 hours, showing that even as ETF fund flows rotate, spot prices remained strong, decoupling from the more volatile fund flow picture.

Outflows from Ethereum and Solana are in sharp contrast

While Bitcoin funds are recovering, the two major altcoin ETF categories are moving in the opposite direction. The split was the clearest sign of the day: funds were withdrawn from Ethereum and Solana products on the same day and diverted to Bitcoin.

Ethereum ETF lost US$48.2 million

On September 2, the U.S. spot Ethereum ETF recorded a net outflow of US$48.2 million. Specifically, ETHA lost US$53.4 million, FETH lost US$26.2 million, and ETHA lost US$23.5 million; while ETHB bucked the trend, increasing US$52.9 million. This makes the situation of the Ethereum fund portfolio very different from the recent strong period when Ethereum ETF surpassed Bitcoin.

Solana ETF lost US$6.1 million

Solana ETF's decline was small but still negative, recording a net outflow of US$6.1 million, and all divestments came from BSOL. This concentrated exit may indicate that investor confidence is relatively weak in younger product systems, although a one-day change is not enough to constitute a trend judgment.

What needs to be carefully discerned is that these outflows may reflect position corrections and changes in sentiment rather than fundamental conclusions about these two assets. It is worth noting that this contrast is particularly prominent given that major crypto assets, including Bitcoin and Ethereum, have jointly attracted capital in recent weeks (for example, Bitcoin and Ethereum ETFs combined attracted US$2.3 billion in one week).

The follow-up focus of traders and readers

It is unclear whether this divergence will continue or reverse in the next few trading sessions. If the continued inflow led by IBIT is confirmed, it means that the rebound is effective; if a new Bitcoin outflow date occurs, the September 2 market may be regarded as just noise.

It is recommended to focus on three signals:

1. Whether the momentum of Bitcoin ETF can be maintained after a single trading session;
2. Whether outflows from Ethereum and Solana have stabilized or deepened;
3. Whether the strength of spot prices continues to deviate from the flow of funds.

Overall market sentiment remained constructive. At the time of data collection, the "Cryptocurrency Fear and Greed Index" was at 65 points, which was in the "greedy" range.
