Crypto exchange-traded funds (ETFs) trading on US spot markets saw a robust net inflow totaling $214.95 million on March 13, 2026. The lion’s share of this influx targeted Bitcoin ETFs, with BlackRock commanding a substantial portion of the activity. Not only did the asset management giant record the highest volume on both its Bitcoin and Ethereum products, but it also dominated the market throughout the trading day with consistent, sizable acquisitions.
Bitcoin ETF Inflows Surge on Institutional Appetite
Bitcoin ETFs alone enjoyed $180.4 million in net inflows on the day, equating to the acquisition of 2,560 Bitcoins. BlackRock’s IBIT fund stole the spotlight, amassing 2,040 Bitcoins—worth $143.6 million—accounting for nearly 80% of the aggregate daily Bitcoin ETF inflows. Fidelity’s FBTC product contributed with the purchase of 329 Bitcoins, corresponding to $23.2 million in fresh capital, while other Bitcoin ETFs logged more modest but steady growth.
BlackRock’s single-day purchase of over 2,000 Bitcoins coincided with exchange Bitcoin supplies dropping to the lowest levels seen since 2017. As ETFs move large amounts of Bitcoin into cold storage wallets, the available liquid supply contracts further, putting additional pressure on market liquidity.
Ethereum and Altcoin ETFs Garner Steady Interest
Ethereum ETFs posted net inflows totaling $26.7 million during the same timeframe, representing purchases of 12,882 Ether. BlackRock’s combined activity in both Bitcoin and Ethereum ETFs reached 15,633 Ether acquired for $32.4 million. Fidelity followed suit, acquiring 1,061 Ethereum for a total of $2.2 million. Interest has been notably strong for BlackRock’s newly launched staked Ether ETF, which quickly attracted attention from market participants in its opening days.
Elsewhere, Solana ETFs recorded a $7.6 million inflow following the release of Grayscale’s new Solana analysis report, resulting in the acquisition of 87,568 SOL. The report highlights that SOL’s price remains 67% below its September 2025 peak. Dogecoin and Chainlink ETFs saw more modest interest, bringing in $193,000 and $324,000, respectively.
Litecoin ETFs bucked the trend, experiencing a net outflow of $271,000 as investors withdrew 4,890 LTC from funds. Products linked to AVAX, HBAR, and XRP registered little to no significant transaction activity throughout the period.
Institutional Players Shape Crypto ETF Momentum
The daily net inflow of nearly $215 million supports the narrative of sustained institutional demand driving the crypto ETF space over the past month. Robert Mitchnick, BlackRock’s Head of Digital Assets, emphasized during a television interview on March 12 that investors in IBIT predominantly maintain long-term positions, with many seeing market pullbacks as buying opportunities.
Mitchnick highlighted that most of his clients are holding for the long term and tend to increase their exposure when prices dip.
Following Bitcoin’s dip to $66,000 on March 9, institutional products quickly added $180 million in new Bitcoin positions over just four days. The market continues to see vigorous institutional participation despite the absence of clear signals that a market bottom has been established.
