Spot Bitcoin ETFs Post $7.81M Net Inflow on March 25 as Ethereum ETFs Record Outflows

U.S. spot Bitcoin ETFs recorded a combined net inflow of $7.81 million on March 25 (ET), while spot Ethereum ETFs posted net outflows on the same day, highlighting a continued divergence in institutional appetite between the two largest crypto assets.

The modest positive flow into Bitcoin ETF products contrasts with the previous session’s $74.53 million net outflow, suggesting a potential stabilization in demand after a choppy stretch for BTC-linked funds.

Ethereum ETFs, meanwhile, extended a pattern of net redemptions that has persisted through much of March.

Bitcoin ETF Inflows and Ethereum ETF Outflows: March 25 Flow Data Breakdown

Across all U.S.-listed spot Bitcoin ETF products, net inflows totaled $7.81 million for the trading day ending March 25 (ET), according to data tracked by Wu Blockchain.

The figure is relatively modest compared to the multi-hundred-million-dollar inflow days that major fund launches like Morgan Stanley’s MSBT have generated. However, any positive flow day marks a shift from the outflow pressure that characterized several recent sessions.

On the Ethereum side, spot ETH ETFs recorded a net outflow on March 25. The exact aggregate dollar figure was not fully broken down in available reporting, but the direction was clear: capital continued to exit Ethereum-linked ETF products.

Ethereum ETF products have consistently lagged their Bitcoin counterparts in flow momentum since launch. March has been particularly challenging, with multiple sessions of net outflows across the month.

What the March 25 ETF Flow Divergence Signals for Crypto Investors

The $7.81 million Bitcoin ETF inflow is best characterized as cautious accumulation rather than aggressive institutional buying. It represents a fraction of the daily flows seen during peak demand periods but is nonetheless a positive data point following consecutive outflow sessions.

The BTC-ETH divergence on March 25 is not an anomaly. Since the launch of spot Ethereum ETFs, flows into ETH products have generally trailed Bitcoin ETFs by a significant margin in both volume and consistency.

Bitcoin vs. Ethereum ETF Flows: A Persistent Gap

Several factors contribute to the gap. Bitcoin’s first-mover advantage in the spot ETF market gave it a deeper liquidity base and stronger brand recognition among traditional finance allocators. Ethereum’s more complex value proposition, tied to smart contracts and staking yield rather than a straightforward digital-gold narrative, has made it a harder sell for conservative institutional portfolios.

The broader digital asset ecosystem continues to evolve, with competing Layer-1 platforms also vying for institutional attention. This fragmentation of the altcoin narrative may further dilute demand for ETH-specific products relative to Bitcoin’s clearer positioning.

For context, earlier in March, Ethereum spot ETFs recorded an $82.85 million net outflow in a single session, according to reporting on March 6 flow data. The March 25 outflow appears smaller in scale, though the continued negative direction underscores persistent headwinds.

Daily ETF flow data remains one of the most closely watched indicators for gauging institutional crypto sentiment. The next several sessions will show whether Bitcoin’s return to positive flows marks the beginning of a renewed accumulation phase or proves to be a one-day pause in a broader cooling trend.
