U.S. spot crypto ETFs recorded $867.2 million in combined net inflows for the week of March 9 to 13, 2026, with total AUM across all products reaching $106 billion, as institutional buying accelerated during the same week Bitcoin bounced from $66,000 back above $70,000.
The Bitcoin ETF Flows
According to data from SoSoValue, Bitcoin ETFs led the week with $763.40 million in net inflows, representing 11,117 BTC purchased across all products. BlackRock was the dominant buyer, acquiring 8,727 BTC during the week, accounting for roughly 78% of total Bitcoin ETF purchases. Fidelity added 2,170 BTC. VanEck bought 211 BTC. ARK 21Shares purchased 96 BTC. Bitwise bought 135 BTC on the Bitcoin side while Valkyrie sold 60 BTC and Grayscale sold 150 BTC, the only net sellers on the Bitcoin side for the week.
The 11,117 BTC purchased by ETFs in a single week adds context to the exchange supply data covered earlier today. Bitcoin sitting on exchanges has already fallen to its lowest level since November 2017. ETF products absorbing over 11,000 BTC in one week removes that supply permanently into cold custody, compressing available exchange inventory further with each passing week.
The Ethereum ETF Flows
Ethereum ETFs recorded $117.40 million in net inflows, representing 62,013 ETH purchased across products. Fidelity was the largest Ethereum buyer at 49,538 ETH. Grayscale added 3,416 ETH despite selling Bitcoin. ARK 21Shares purchased 517 ETH. Franklin added 390 ETH. Bitwise sold 3,373 ETH, the only meaningful Ethereum outflow for the week.
The Ethereum inflows arrive the same week BlackRock launched its staked Ether ETF and the Ethereum Foundation announced its 70,000 ETH staking initiative. Institutional appetite for ETH exposure is building precisely as the asset trades near its multi-cycle trendline support covered earlier this week.
The Altcoin ETF Picture
XRP ETFs recorded the only significant outflow among altcoins, with $28.07 million leaving and 20.76 million XRP sold. Every other altcoin ETF recorded positive or zero flows. Solana ETFs attracted $10.70 million with 121,800 SOL purchased. Chainlink added $2.653 million. Polkadot recorded $544,480 in inflows. HBAR attracted $655,150 and Dogecoin $193,360. Litecoin recorded a small outflow of $271,260. Avalanche recorded zero flows in both directions.
What the Weekly Total Means
$867 million in a single week during a bear market, while Bitcoin was recovering from a $66,000 low and DeFi lending deposits were falling 36% from their peak, describes a specific type of capital. It is not retail speculation. It is institutional allocation operating on a timeline that ignores weekly price volatility entirely.
As Robert Mitchnick noted in his CNBC interview covered earlier today, 90% of BlackRock’s IBIT holders are long-term focused retail and advisor clients who buy the dip. The $867 million weekly inflow during what many analysts are calling a bear market is that behaviour expressed at scale across the entire institutional ETF ecosystem.
