Bitcoin, Ethereum, Solana, and XRP spot ETFs all recorded net inflows on the same day, adding roughly $65 million combined. The synchronized gain follows a record week for Bitcoin ETFs and a single-day inflow record for Solana, with staking features and resolved regulatory uncertainty cited as reasons Solana and XRP are drawing fresh institutional money.
Bitcoin, Ethereum, Solana, and XRP spot ETFs each recorded net inflows simultaneously on September 28, according to data from SoSoValue, pushing the day's combined total to roughly $65 million.
Where the money went
Bitcoin ETFs led the day with $31.07 million in net inflows, though that was actually the lowest single-day figure for Bitcoin ETFs that month. Ethereum followed at $17.10 million. Solana took in $12.70 million, and XRP added $3.96 million.
Those daily figures look small next to the cumulative totals. Bitcoin spot ETFs have now absorbed $57.58 billion in total net inflows since their January 2024 launch. Total net assets sit at $107.82 billion, equal to 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.
The week leading into this moment set the stage. Bitcoin ETFs pulled in approximately $2.39 billion the week ending around September 25, the largest single-week figure of 2026, enough to push Bitcoin ETFs' 2026 net flows positive after earlier redemptions had dragged the year-to-date figure negative. Solana, meanwhile, 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 drawing institutional interest
The issuer lineup behind these products includes BlackRock, Fidelity, Bitwise, and Grayscale, competing on fees and product structure. Solana ETFs carry a feature Bitcoin and Ethereum products currently lack: staking integration, with some structures passing through staking yield to holders and turning passive index exposure into something closer to a yield-bearing position.
XRP's trajectory follows its own path. The asset spent years in regulatory limbo following the SEC's lawsuit against Ripple, and 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 its cumulative inflows since the late 2025 launch.
