Large $422 million inflow into Bitcoin ETFs as BlackRock dominates with $351 million
Bitcoin exchange-traded funds recorded $422 million in inflows on May 1, led by BlackRock’s IBIT, which added $351 million.
The move followed Thursday’s outflow, which broke an eight-day win streak and pushed cumulative net flows for US-listed spot Bitcoin ETFs back to $39.5 billion since their launch (including Grayscale outflows), according to Farside Investors’ data.
Total Bitcoin ETF AUM across both spot funds has reached $112 billion as the Bitcoin price continues to rise well above ETF launch prices. BlackRock’s IBIT alone has had total inflows of an AUM of $58 billion, or 597k BTC.
The gap in net cumulative flows and AUM is mainly due to the price appreciation of Bitcoin since those inflows arrived (plus a few small items such as accrued cash, fees, and rounding). Net inflows are historical costs; AUM is marked‑to‑market.
Fidelity’s FBTC and Bitwise’s BITB saw smaller gains of $29.5 million and $38.4 million, respectively, while Grayscale’s GBTC posted $16 million in net inflows after prolonged outflows.

| Grayscale | GBTC | 1.50% | -32.0 | 16.0 | -22,747 |
| Grayscale | BTC | 0.15% | 0.0 | 41.9 | 1,288 |
| Total | -56.3 | 422.5 | 39,532 |
The renewed inflows arrived as Bitcoin surpassed $97,000 on May 2, drawing attention to the feedback loop between spot prices and ETF demand.
The gap between the largest issuers remains wide. While BlackRock and Fidelity benefit from deep distribution networks, smaller players such as Valkyrie and VanEck recorded little or no daily flow.
Competitive pressures may grow as Grayscale considers pricing adjustments to stem outflows and maintain relevance in a rapidly maturing ETF landscape.
