U.S. Spot Crypto ETFs Pulled In $214 Million on March 13 – BlackRock Bought the Most

U.S. spot crypto ETFs recorded approximately $214.95 million in net inflows on March 13, 2026, with Bitcoin ETFs leading the way and BlackRock accounting for the majority of purchases across both Bitcoin and Ethereum products.

The Bitcoin ETF Flows

According to data from SoSoValue, Bitcoin ETFs attracted $180.40 million in net inflows, representing 2,560 BTC purchased across all products. BlackRock’s IBIT drove the majority of that activity, buying 2,040 BTC worth $143.60 million, roughly 80% of the total Bitcoin ETF inflow for the day. Fidelity’s FBTC added 329 BTC worth $23.20 million. The remaining balance was distributed across other products in the Bitcoin ETF suite.

BlackRock’s single-day Bitcoin purchase of 2,040 BTC is notable in the context of the exchange supply data covered earlier this week. Bitcoin leaving exchanges is already at its lowest level since 2017. ETF products absorbing 2,560 BTC in a single session removes that supply from circulation permanently into cold custody, compressing available supply further with each passing day.

Ethereum and Altcoin ETF Flows

Ethereum ETFs recorded $26.70 million in inflows, representing 12,882 ETH purchased. BlackRock added 15,633 ETH worth $32.40 million across its combined Bitcoin and Ethereum ETF operations on the day. Fidelity added 1,061 ETH worth $2.20 million. The Ethereum inflows arrive the same week BlackRock launched its staked Ether ETF, as covered in earlier reporting, suggesting the new product is already generating initial demand.

Solana ETFs attracted $7.60 million in inflows representing 87,568 SOL, a meaningful figure given Grayscale’s bullish Solana thesis published the same day arguing the asset trades 67% below its September 2025 highs. Dogecoin ETFs recorded $193.36K in inflows and ChainLink ETFs added $324.61K.

Litecoin was the only asset recording outflows, with 4,890 LTC worth $271.26K leaving. AVAX, HBAR, and XRP ETFs recorded zero flows on the day.

What the Total Figure Represents

The $214.95 million single-day total follows the pattern of sustained institutional inflows documented across the past month. As Robert Mitchnick noted in his CNBC interview on March 12, 90% of IBIT’s investor base consists of long-term holders who buy the dip. The March 13 flow data is that behaviour expressed in real numbers. Bitcoin dropped to $66,000 on March 9. Four days later, institutional products absorbed $180 million in fresh Bitcoin exposure.

The money is not waiting for the bottom to be confirmed. It is arriving while the debate about where the bottom is continues.
