Bitcoin (BTC) ETFs Pulled in $2B in April: Can the Flows Continue in May?

• BlackRock's IBIT ETF alone contributed roughly $2 billion in net subscriptions during April, accounting for more than the entire category's total inflows as other funds experienced outflows
• Cumulative Bitcoin ETF inflows since January 2024 reached $58 billion with total net assets of $103.78 billion, despite the week ending May 15 posting $1.16 billion in gross outflows against just $158 million in inflows
• The U.S.-China trade deal and 90-day tariff pause on April 9 caused the Fear and Greed Index to jump from 18 to 39 in a single day, driving institutional capital back into Bitcoin ETFs alongside traditional markets

Bitcoin ETF Market Summary

Key Performance Metrics

Bitcoin ETFs recorded approximately $2 billion in net inflows during April 2026, marking the strongest monthly performance of the year. Cumulative inflows since January 2024 reached $58 billion, with total net assets hitting $103.78 billion.

May began strongly with $629.73 million flowing in on May 1 and $532.21 million on May 4. However, a $1 billion weekly outflow during the week ending May 15 broke a six-week inflow streak.

Leading Players

BlackRock's IBIT dominated the market, attracting roughly $2 billion in net subscriptions in April alone—exceeding total category inflows as other funds like Grayscale's GBTC posted outflows. On May 4, IBIT led with $335.49 million, while Fidelity's FBTC added $184.57 million.

Market Drivers

April's momentum was fueled by three catalysts:

• U.S.-China tariff pause announced April 9
• Bitcoin recovery toward $80,000 (approaching the 200-day moving average of $82,455)
• Strong institutional conviction through BlackRock's IBIT

May's reversal resulted from:

• Rising Treasury yields following a 3.8% CPI print
• Fed rate cut probability declining (rate hike probability jumped to 44%)
• Bitcoin's failure to sustain momentum above $80,000
• Profit-taking after April's rally

Outlook

Analysts suggest May inflows could resume if inflation moderates and the Fed signals potential rate cuts. However, continued high Treasury yields pose significant headwinds as institutions rotate toward safer bond allocations. Bitcoin maintaining levels above $80,000 remains critical for renewed institutional demand.
