XRP ETFs Were the Only U.S. Crypto Fund Group Taking In Money on Tuesday

The five U.S. spot XRP ETFs pulled in nearly $2 million on Tuesday, Sept. 8 — the only meaningful inflow anywhere in the U.S. crypto ETF market that day, according to SoSoValue figures reported by CoinDesk. That leaves the group at $1.69 billion in cumulative inflows and $173 million over the trailing 30 days.

Everything bigger moved the other way, and Grayscale did most of the damage. U.S. spot bitcoin ETFs lost roughly $47 million on net, but Grayscale's GBTC alone shed $66 million in redemptions; BlackRock's IBIT, Bitwise's BITB, Ark and 21Shares' ARKB and Morgan Stanley's MSBT together added about $41 million, partly offsetting the outflow. The ether complex ran the same pattern: Grayscale's two ether products bled a combined $34 million and Fidelity's FETH lost $10 million, leaving ether ETFs down about $24 million on the day, with every other ether fund flat. Hyperliquid-linked ETFs lost $13 million and solana funds under $1 million, per the same data.

Bitcoin ETF net assets closed at $99.52 billion — back below the $100 billion mark the category first crossed on Sept. 3.

The real-world read

Frame the XRP "standout" for what it is: a single day's ~$2 million is a rounding error against a bitcoin complex holding roughly $99.5 billion, and one green day doesn't establish a trend. The more durable story is the fee arbitrage CoinDesk flags — GBTC's 1.50% expense ratio against IBIT's 0.25% has driven Grayscale outflows into cheaper rivals all year, and Tuesday fit the pattern: Grayscale supplied $66 million of $66 million-plus in gross bitcoin redemptions while its lower-fee competitors took in money. The ether side told the same story. Two caveats worth holding: these are one-day, unaudited flow estimates from a single aggregator (SoSoValue), not confirmed issuer filings, and daily ETF flows are noisy — read the direction, not the decimal.
