Every major cryptocurrency spot ETF recorded net inflows on September 28, marking a coordinated positive day across Bitcoin, Ethereum, Solana, and XRP products. The combined total reached roughly $65 million, according to data from SoSoValue.
Bitcoin ETFs led with $31.07 million in net inflows, followed by Ethereum at $17.10 million, Solana at $12.70 million, and XRP at $3.96 million.
Cumulative Performance and Market Penetration
Bitcoin spot ETFs have absorbed $57.58 billion in total net inflows since launching in January 2024, with total net assets now at $107.82 billion. This represents 6.42% of Bitcoin's entire market cap held within 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 accumulated $1.79 billion in cumulative inflows, while Solana's tally sits at $1.62 billion. Solana and XRP products entered the market in 2025, following Bitcoin's January 2024 launch and Ethereum's May 2024 debut.
Recent Momentum
The week ending around September 25 set the stage for the synchronized inflows. Bitcoin ETFs pulled in approximately $2.39 billion that week alone, the largest single-week figure of 2026, pushing Bitcoin ETFs' 2026 net flows into positive territory after earlier redemptions had made the year-to-date figure negative. Solana recorded a single-day inflow record of $86.7 million on September 25.
Competitive Landscape and Product Differentiation
The issuer lineup for these products includes BlackRock, Fidelity, Bitwise, and Grayscale, competing on fees and product structure.
Solana ETFs offer staking integration, a feature currently absent from Bitcoin and Ethereum products. Some Solana ETF structures pass through staking yield to holders, transforming passive index exposure into yield-bearing positions.
XRP's growth reflects resolution of the asset's regulatory history. Following the SEC's lawsuit against Ripple, which has now been resolved, regulated ETF vehicles have attracted investors who were previously unable to access the asset through institutional channels.
