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.
BlackRock Leads as ETH and SOL Follow
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.
XRP ETFs Buck the Trend
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.
