Bitcoin, Ethereum, Solana, and XRP spot ETFs all post net inflows on Sept. 28
All four major crypto spot ETFs pulled in a combined $65 million on the same day, a signal that institutional appetite is spreading well beyond Bitcoin.
Every major crypto spot ETF had a good day on September 28. Bitcoin, Ethereum, Solana, and XRP products each recorded net inflows simultaneously, according to data from SoSoValue, bringing the day’s combined total to roughly $65 million.
Where the money went
Bitcoin ETFs led on the day with $31.07 million in net inflows, which was actually the lowest single-day figure for Bitcoin ETFs during that month. Ethereum followed at $17.10 million, Solana at $12.70 million, and XRP at $3.96 million.
Those daily numbers look small against the cumulative picture. Bitcoin spot ETFs have now absorbed $57.58 billion in total net inflows since launching in January 2024, with total net assets sitting at $107.82 billion. That represents 6.42% of Bitcoin’s entire market cap sitting inside regulated ETF wrappers.
Ethereum’s cumulative net inflows stand at $13.96 billion against $17.69 billion in total assets. XRP ETFs, which launched in late 2025, have already accumulated $1.79 billion in cumulative inflows. Solana’s tally sits at $1.62 billion.
Solana and XRP products only came to market in 2025, after Bitcoin’s January 2024 launch and Ethereum’s May 2024 follow-on.

The week ending around September 25 set the stage for this. Bitcoin ETFs pulled in approximately $2.39 billion that week alone, the largest single-week figure of 2026, enough to push Bitcoin ETFs’ 2026 net flows into positive territory after earlier redemptions had dragged the year-to-date figure negative. Solana set a single-day inflow record of $86.7 million on September 25, just three days before the synchronized four-asset inflow day.
Why Solana and XRP are picking up institutional interest
The issuer lineup for these products includes BlackRock, Fidelity, Bitwise, and Grayscale, competing on fees and product structure.
Solana ETFs carry an additional feature that Bitcoin and Ethereum products currently lack: staking integration. Some Solana ETF structures pass through staking yield to holders, which turns a passive index exposure into something closer to a yield-bearing position.
XRP’s trajectory is its own story. The asset spent years in regulatory limbo following the SEC’s lawsuit against Ripple. With that resolved and ETFs now live, pent-up demand from investors who were waiting for a regulated vehicle is the most straightforward explanation for $1.79 billion in cumulative inflows in a relatively short window since the late 2025 launch.
