US spot Bitcoin exchange-traded funds continued their aggressive inflow streak this week, attracting nearly $1 billion in fresh capital over two trading sessions as Bitcoin climbed back above the $80,000 level.

According to SoSoValue data, spot Bitcoin ETFs recorded $467.4 million in net inflows on Tuesday after adding another $532 million on Monday, extending a broader recovery trend that has accelerated alongside Bitcoin’s rebound above $81,000.

The latest inflows push total ETF allocations since May 1 to roughly $1.63 billion, while cumulative net inflows have now reached $59.7 billion. Assets under management across US spot Bitcoin ETFs have also climbed to approximately $109 billion, their highest level so far this year.

Bitcoin ETF demand remains resilient despite market volatility

The surge in inflows comes even as markets digest fresh uncertainty surrounding Michael Saylor and Strategy after the company signaled it may consider selective Bitcoin sales despite previous promises of "never selling any Bitcoin."

Despite those concerns — alongside Bitcoin’s earlier 50% drawdown during the current market cycle — ETF demand has remained remarkably stable.

Bloomberg ETF analyst Eric Balchunas noted that while Bitcoin fell roughly 50% from its highs, ETFs only experienced around 8% outflows, suggesting institutional investors continued holding exposure through traditional financial vehicles even during periods of heavy volatility.

Speaking to Roxom TV, Balchunas credited the resilience to Wall Street’s distribution networks and the accessibility ETFs provide to traditional investors.

“Don’t underestimate the firepower of Wall Street wholesalers!”

The trend reinforces a growing market narrative that spot Bitcoin ETFs are becoming a structural demand layer for crypto markets, helping stabilize capital flows during both rallies and sharp corrections.

Institutional appetite expands beyond Bitcoin

Momentum has also begun spilling into altcoin investment products as broader crypto sentiment improves.

Spot Ether ETFs recorded $97.6 million in inflows on Tuesday, while XRP funds attracted $11.3 million. Solana ETFs added smaller but positive inflows totaling $1.7 million.

Dogecoin ETFs also returned to positive territory for the first time since late April, pulling in roughly $400,000 and pushing cumulative inflows above $10 million.

The broad-based inflows suggest institutional investors are gradually expanding beyond Bitcoin exposure as crypto markets recover, with ETFs increasingly functioning as the primary gateway for regulated digital asset investment.

After posting $1.97 billion in inflows during April, Bitcoin ETFs now appear to be carrying that momentum into May, reinforcing their growing role as one of the strongest drivers of institutional crypto demand in the current market cycle.
