Bitcoin (BTC) spot ETFs recorded $767 million in net inflows from March 9 to March 13, with BlackRock’s IBIT accounting for $600.1 million of that total.
Grayscale’s GBTC remained the largest seller, posting $25.9 million in net outflows during the same period.
The five-day streak marked the first unbroken run of daily inflows for BTC ETFs in 2026, according to SoSoValue data.
On-chain analytics firm Arkham confirmed BlackRock’s dominance in the weekly ETF race. IBIT alone absorbed more than 78% of all net BTC inflows. This reinforces the asset manager’s position as the largest institutional buyer of Bitcoin through regulated products.
Ethereum (ETH) spot ETFs also extended their momentum, pulling in $160.9 million over the same window. Fidelity’s FETH led purchases at $90.1 million, while Grayscale’s ETHE saw $13.4 million in outflows.
Solana (SOL) spot ETFs posted a modest $10.7 million in net inflows, signaling early institutional interest in the asset class.
While capital flowed into BTC, ETH, and SOL products, XRP (XRP) spot ETFs diverged sharply. The funds recorded $28.07 million in net outflows during the week, making XRP the only major crypto ETF category to see withdrawals.
The outflows add to a difficult March for XRP ETFs, which have seen persistent institutional selling despite the token’s cumulative ETF inflows still sitting above $1.2 billion since launch.
Whether this divergence reflects a temporary rotation or a deeper shift in institutional sentiment toward XRP remains an open question heading into the second half of March.
