BlackRock ETHA Leads: Ethereum Spot ETF Continues to Attract Funds, Bitcoin ETF Inflows Slow Down

On April 22, 2026, Gate market data shows that ETH is quoted at approximately $2,360, with a 24-hour increase of 2.3%; BTC is quoted at approximately $78,010, with a 24-hour increase of 2.78%. While prices are gradually rising, structural changes in ETF capital flows are occurring—Ethereum spot ETFs have recorded nine consecutive days of net inflows, whereas Bitcoin spot ETFs lag significantly behind in capital inflow scale. Is this divergence in capital flows a short-term disturbance or the beginning of a long-term trend?

Who is Leading the Capital Inflow Structure of Ethereum ETFs

According to SoSoValue data, on April 21, the total net inflow into Ethereum spot ETFs was $43.3589 million, continuing nine consecutive days of positive capital flow. The persistence of this trend is far more significant than the absolute daily value—the nine-day consecutive net inflows form a statistically meaningful signal sequence, not just short-term fluctuations caused by isolated events.

Specifically, the ETHA product issued by BlackRock led all Ethereum ETFs with a single-day net inflow of $37 million, bringing its total net inflow to $11.94B. BlackRock’s staked version ETHB also contributed a net inflow of $15.4593 million, with a total net inflow of $424 million. Grayscale’s Ethereum Trust ETF ETHE experienced a net outflow of $12.1355 million, with total net outflows reaching $5.23B. As of April 21, the total net asset value of Ethereum spot ETFs was $13.67B, accounting for 4.89% of Ethereum’s total market cap. The total net inflow has reached $12.06B historically.

This pattern clearly indicates that the current continuous net inflow into Ethereum ETFs is not a broad industry-wide recovery but is driven by flagship products of leading asset managers. Aside from contributions from BlackRock’s ETHA and ETHB, other products generally show slight net outflows.

Why Is Bitcoin ETF Capital Inflow Significantly Lower Than Ethereum

On April 21, the US Bitcoin spot ETF recorded a net inflow of $11.8 million, roughly a quarter of the Ethereum ETF inflow during the same period. Breaking down at the product level, the internal capital structure of Bitcoin ETFs also shows differentiation: BlackRock’s IBIT led with a net inflow of $39.3 million, and Morgan Stanley’s MSBT had a net inflow of $10.8 million; meanwhile, Fidelity’s FBTC experienced a net outflow of $6.6 million, Bitwise’s BITB outflow of $12.7 million, ARK’s ARKB outflow of $14.5 million, and Grayscale’s GBTC outflow of $17.5 million. Grayscale’s Mini BTC experienced a net inflow of $17.3 million, partially offsetting the outflows from GBTC.

The relatively weak scale of Bitcoin ETF inflows does not mean institutions are retreating from the crypto market. In fact, Bitcoin ETFs experienced nine consecutive days of positive inflows from April 8 to April 20, with BlackRock’s IBIT accumulating about $1.61B during this period. On April 20, Bitcoin spot ETFs still recorded a net inflow of $238 million. Therefore, the $11.8 million inflow on April 21 should be understood as a phase of incremental capital convergence rather than a trend reversal.

Is Capital Moving from Bitcoin ETFs to Ethereum ETFs

The key to understanding the difference in capital flows between the two ETF types lies in whether it is “stock transfer” or “incremental rebalancing.”

If institutions are systematically selling Bitcoin ETF holdings to buy Ethereum ETFs, then the capital flows should show a significant inverse correlation. However, based on the data during the same period, the Bitcoin ETF market did not experience corresponding drastic capital outflows. A more accurate description might be “incremental capital rebalancing”—some newly allocated funds or previously cautious capital are choosing to prioritize or increase their allocation to Ethereum ETFs.

The continuous net inflow of Ethereum ETFs began around mid-April. In the week before (up to the week ending April 10), weekly inflows into Ethereum ETFs rose to $187 million, completely reversing the previous three weeks’ cumulative outflows of about $308 million. During the same period, Bitcoin ETFs still maintained net inflows. This indicates that institutions are not “selling Bitcoin to buy Ethereum,” but rather adjusting the weights of their digital asset portfolios between the two core assets.

Why Can BlackRock Dominate Both ETF Markets Simultaneously

BlackRock demonstrates overwhelming product competitiveness in both Bitcoin and Ethereum ETF markets. In Bitcoin ETFs, IBIT led with a single-day net inflow of $39.3 million; in Ethereum ETFs, ETHA and ETHB together contributed about $52.5 million, accounting for 121% of the total net inflow into Ethereum ETFs that day (partially offset by outflows from other products).

This dominance stems from BlackRock’s systemic advantages as the world’s largest asset manager. Its compliance framework, distribution channels, and market-making support enable it to reach institutional clients that other issuers find difficult to access, including pension funds, endowments, and wealth management platforms. The sustained inflow into ETHA not only reflects BlackRock’s sales capabilities but also indicates that its large and strictly demanding institutional client base’s collective judgment of Ethereum’s investment value is shifting from “exploratory allocation” to “fundamental allocation.”

What Fundamental Factors Support Continuous Capital Inflows into Ethereum ETFs

Institutional interest in Ethereum typically rises due to changes in asset fundamentals or relative valuation reassessment. Recently, the Ethereum network has made substantial progress across multiple dimensions: Layer 2 scaling solutions continue to lower transaction costs, real-world asset tokenization use cases are expanding, and post-EIP-1559 supply dynamics are trending toward deflation.

On-chain data also provides validation. Ethereum’s daily transaction volume increased by approximately 41% compared to the previous week, reaching about 3.6 million transactions, nearly vertical from around 2.5 million on April 10. Tether issued an additional 1 billion USDT on the Ethereum network, with the stablecoin supply expansion seen as a leading indicator of potential buying power. Asset management firm Bitmine increased its ETH holdings by 101,627 coins in the third week of April, the largest weekly purchase since 2026, with total holdings accounting for 4.12% of Ethereum’s total supply. These fundamental signals collectively underpin the logic for institutional continuous allocation to Ethereum.

How Will the Capital Divergence Between the Two ETF Types Affect ETH and BTC Pricing

The scale difference in ETF capital inflows does not necessarily translate into a linear relationship with price performance. The marginal effect of capital allocation needs to be understood within the broader market structure.

With nine days of continuous inflows into Ethereum ETFs, ETH broke through $2,400 on April 22, with a 3.57% increase over 24 hours. Market prediction data from Polymarket shows that the probability of ETH reaching $2,600 before the end of April has risen to 33%, while the probability of falling below $2,000 is only 18%. For Bitcoin, BTC surpassed $78,000, with the market’s probability of reaching $80,000 in April rising to 46%. Both assets are gradually rising supported by ETF capital inflows.

From a longer-term perspective, the cumulative net inflows of the two ETFs still differ significantly in scale. Ethereum ETFs have accumulated over $12.06B in net inflows historically, while Bitcoin ETFs have exceeded the trillion-dollar mark. The inflows into Ethereum ETFs more reflect an incremental increase in institutional allocation rather than a substitution for Bitcoin.

Key Variables That Will Determine Whether the Capital Divergence Can Continue

Assessing whether Ethereum ETF capital inflows can sustain surpassing Bitcoin ETF inflows depends on several core variables. First, the implementation pace of Ethereum’s technological upgrade roadmap. Vitalik Buterin announced a five-year roadmap on April 20, focusing on quantum security, ZK-EVM scaling, and protocol resilience, providing a long-term narrative support. Second, changes in the macro liquidity environment—if risk appetite continues to recover, funds may flow more into higher-volatility, more elastic assets, with Ethereum often seen as a representative. Third, the evolution of ETF product structures—BlackRock’s dual-product strategy with ETHA and ETHB effectively covers staking yield and traditional spot exposure needs; whether this product matrix will be replicated by other issuers will influence the competitive landscape of Ethereum ETFs.

Summary

On April 21, Ethereum spot ETFs recorded a net inflow of $43.4 million, while Bitcoin ETFs saw $11.8 million in net inflows. The divergence in capital flows between the two products reflects institutions’ internal rebalancing of crypto asset allocations. Ethereum ETFs have experienced nine consecutive days of net inflows, driven by structured buying led by BlackRock’s ETHA, indicating that institutional perceptions of Ethereum’s investment value are shifting from exploratory to fundamental allocation. This movement is not a “stock transfer” of existing funds but a redistribution of incremental capital within digital asset portfolios. On-chain transaction volume growth, stablecoin issuance, and leading institutional holdings support this trend. The continuation of capital divergence between the two ETFs depends on the implementation of Ethereum’s technical roadmap, macro liquidity conditions, and further evolution of ETF product structures.

FAQ

Q1: What is the significance of Ethereum spot ETFs’ nine consecutive days of net inflows in history?

A: The nine consecutive days of positive capital inflows form a statistically meaningful signal sequence, indicating that institutional behavior patterns may be undergoing substantive change rather than being driven by short-term emotional buying.

Q2: Why can BlackRock’s ETHA continue to attract capital?

A: As the world’s largest asset manager, BlackRock’s compliance framework, distribution channels, and market-making support enable it to reach institutional clients that other issuers find difficult to access. The inflow into ETHA reflects the collective judgment of these institutional clients on Ethereum’s investment value.

Q3: Is capital moving from Bitcoin ETFs to Ethereum ETFs?

A: Based on the data during the same period, the Bitcoin ETF market did not experience corresponding drastic capital outflows. A more accurate description is “incremental capital rebalancing”—newly allocated funds or previously cautious capital are prioritizing or increasing their allocation to Ethereum ETFs rather than systematically selling Bitcoin ETF holdings.

Q4: Can the inflow trend of Ethereum ETFs continue?

A: Sustained continuation depends on the implementation pace of Ethereum’s technical roadmap, macro liquidity conditions, and the evolution of ETF product structures. The roadmap announced on April 20 provides long-term narrative support.

Q5: Will the capital divergence between the two ETFs directly drive ETH and BTC prices higher?

A: There is a transmission mechanism between ETF capital inflows and price performance, but it is not linear. Increased capital inflows enhance marginal buying power, but prices are also influenced by market sentiment, liquidity environment, and on-chain activity. As of April 22, ETH broke through $2,400, and market data shows bullish sentiment is rising.

Q6: Why does Grayscale’s ETHE continue to outflow?

A: The persistent outflow from Grayscale’s ETHE is mainly related to its higher fee structure. In contrast, new products like BlackRock’s ETHA, with more competitive fee rates, attract institutional funds seeking low-cost exposure.
