U.S. spot Bitcoin ETFs recorded approximately $202 million in net inflows on March 16, 2026 (Eastern Time), extending a positive streak to six consecutive days of inflows.
This marks renewed institutional demand after earlier periods of hesitation or outflows in 2026. BlackRock’s iShares Bitcoin Trust (IBIT) led the day with around $139 million or up to $139.4 million in some reports, accounting for the majority of the inflows.
Fidelity’s Wise Origin Bitcoin Fund (FBTC) followed with roughly $64-65 million. Other funds contributed smaller amounts, with minor outflows in a few cases; VanEck’s HODL saw some outflow. Total assets under management (AUM) for these ETFs reached about $95.77 billion around that time, representing a significant portion around 6.45% of Bitcoin’s overall market cap.

The inflows coincided with Bitcoin’s price action, where BTC was testing levels around $74,000–$76,000 amid a broader relief rally, supported by institutional buying. This $202 million figure reflects a strong but not record-breaking day—earlier in March and prior months saw larger single-day hauls.
The six-day streak (totaling hundreds of millions cumulatively) signals a shift back toward accumulation, helping stabilize and support BTC’s price floor despite ongoing market volatility from factors like geopolitical tensions. March 17 inflows were around $199 million, pushing the multi-day total higher.
Cumulative inflows since early March have exceeded $900 million in some windows, aligning with BTC’s rebound. These flows highlight sustained interest from institutions in Bitcoin as a maturing asset class, with major players like BlackRock and Fidelity dominating the inflows. If the trend continues, it could provide ongoing upward pressure on Bitcoin’s price in the near term.
U.S. spot Ethereum ETFs have shown a positive turnaround in inflows during March 2026, following earlier periods of outflows or mixed performance earlier in the year. The trend has shifted toward consistent net inflows, signaling renewed institutional interest amid Ethereum’s price recovery (ETH trading around $2,000–$2,300 levels) and developments like staking-enabled products.
Approximately $138–$71 million net inflows; reports vary; one source notes $138.28 million, another $71 million total, with BlackRock’s ETHA leading at ~$81.7 million offset by some outflows elsewhere. March 16: Around $35.9 million net inflows, extending a streak.
March 13: $26.7 million net inflows, marking the fourth consecutive day of positive flows (BlackRock’s ETHA led with $32.4 million). March 12: Strong day with $72.4 million net inflows (Fidelity’s FETH led at ~$52 million, BlackRock’s ETHA at ~$18.7 million). March 11: $57 million net inflows (Fidelity FETH and Grayscale contributions prominent).
March 10: $12.6 million net inflows (Fidelity FETH dominant at ~$10.7 million), snapping prior outflows. This reflects a multi-day streak of net inflows at least 5–6 consecutive days in some reports up to mid-March, contrasting with earlier March periods that saw outflows and a broader 2026 context of prior outflow cycles; billions in earlier drawdowns tied to market corrections.
For the week ending around March 14, Ethereum ETFs saw cumulative inflows, though trailing Bitcoin’s stronger weekly hauls ($767 million in BTC ETFs). The third consecutive week of net inflows was highlighted in some updates. Total historical net inflows across spot Ethereum ETFs stand around $11.7–$12 billion, with total assets under management (AUM) reaching $11.8–$12.3 billion representing roughly 4.7–4.8% of Ethereum’s market cap.
BlackRock’s ETHA dominates with billions in cumulative inflows, followed by Fidelity’s FETH ($2.3–$2.4 billion cumulative). Notable drivers: Major players like BlackRock (ETHA and the newer staked ETHB) and Fidelity (FETH) lead inflows, with staking features; BlackRock’s ETHB launch around March 12 boosting appeal for yield-seeking investors.
Inflows coincide with ETH price stabilization and recovery from sub-$2,000 lows, network upgrades, and broader macro shifts. Unlike Bitcoin ETFs’ more robust streaks; aligning with the $202M+ daily BTC inflows referenced earlier, Ethereum flows remain more modest and variable but show clear momentum reversal.
March 2026 marks a rebound phase for Ethereum ETF inflows after prior weakness, driven by institutional accumulation via established funds and emerging staking options. This supports ETH’s price floor and positions it as a maturing asset class, though flows lag Bitcoin’s scale and remain sensitive to macro volatility. If the streak persists, it could exert sustained upward pressure on Ethereum amid ongoing market dynamics.
