Bitcoin, Ethereum, Solana, and XRP Spot ETFs Record Simultaneous Inflows

Bitcoin, Ethereum, Solana, and XRP spot ETFs all recorded net inflows on September 28, according to data from SoSoValue. The four asset classes pulled in a combined total of approximately $65 million on the day.

Bitcoin ETFs led the group with $31.07 million in net inflows, marking the lowest single-day figure for the month. Ethereum followed with $17.10 million, while Solana and XRP products saw $12.70 million and $3.96 million in inflows, respectively.

The cumulative figures highlight the scale of institutional adoption. Since launching in January 2024, Bitcoin spot ETFs have absorbed $57.58 billion in total net inflows, with total net assets reaching $107.82 billion. This accounts for 6.42% of Bitcoin's total market cap.

Ethereum’s cumulative net inflows currently stand at $13.96 billion with $17.69 billion in total assets. Meanwhile, Solana and XRP products, which both launched in 2025, have accumulated $1.62 billion and $1.79 billion in cumulative inflows, respectively.

The synchronized inflows follow a strong week for Bitcoin products, which saw approximately $2.39 billion in inflows for the week ending September 25. This was the largest single-week figure of 2026 for Bitcoin ETFs, pushing their year-to-date net flows into positive territory. Solana also recorded a single-day inflow record of $86.7 million on September 25.

Institutional interest in Solana ETFs is partly attributed to staking integration, which allows some structures to pass staking yield to holders. For XRP, the inflows follow the resolution of the SEC’s lawsuit against Ripple, with the current $1.79 billion in cumulative inflows reflecting pent-up demand for a regulated investment vehicle.

The market for these products includes issuers such as BlackRock, Fidelity, Bitwise, and Grayscale, who continue to compete on fees and product structure.
