U.S. Spot Bitcoin ETFs Pull In $223M on April 23, Extending Inflow Run to Eight Days
U.S.-listed spot Bitcoin ETFs logged about $223 million of net inflows on April 23, 2025, according to Farside Investors, marking an eighth straight session of net buying and underscoring continued institutional appetite for regulated crypto exposure.
Flows were concentrated in a handful of products. BlackRock's iShares Bitcoin Trust (IBIT) led with $167.5 million of net inflows, followed by Ark Invest's ARKB with $71.2 million. Morgan Stanley's newly launched MSBT added $9.4 million, while Grayscale's BTC took in $5.2 million.
Several funds posted outflows. Fidelity's FBTC saw $16.9 million leave, Bitwise's BITB recorded $7.6 million of net redemptions, and VanEck's HODL lost $5.5 million. The split performance points to increasingly selective positioning rather than broad-based buying across the category.
IBIT's continued dominance is widely attributed to BlackRock's brand and distribution reach, along with a 0.25% expense ratio. Analysts say the firm's standing with advisers and institutions helps reinforce a virtuous cycle, as deeper liquidity and visibility can attract additional allocations.
The eight-day inflow streak is being read as a shift in institutional sentiment following earlier bouts of choppy flows after the products launched. Market participants cite improved regulatory clarity, inflation-related demand for alternative stores of value, and post-halving supply dynamics following Bitcoin's April 2024 halving.
Spot Bitcoin ETFs are also drawing comparisons with futures-based ETFs and Grayscale's legacy Bitcoin Trust (GBTC), with spot structures viewed as offering cleaner price exposure than futures products. CoinShares data shows Bitcoin investment products have taken in $12.3 billion in net inflows year-to-date, far outpacing Ethereum and other crypto products.
Strategists also point to the mechanical impact of spot ETF creations on the underlying market: when issuers acquire Bitcoin to back new shares, it can add direct spot demand. JPMorgan analysts estimate each $100 million of ETF inflows typically moves Bitcoin's price by about 12%. On that framework, roughly $1.5 billion in cumulative inflows over the eight-day run could help explain recent gains. Bitcoin traded near $67,000 on April 23, up from around $62,000 at the start of the streak.
FBTC's outflows, despite the broader inflow backdrop, have prompted questions about rotation. Possible drivers cited include differences in liquidity, trading volume, and allocation rebalancing. Fidelity's fee also stands at 0.25%, matching IBIT, but its smaller asset base and lower trading activity may matter for larger institutional orders.
The first wave of U.S. spot Bitcoin ETFs launched on January 11, 2024, following SEC approval of 11 funds. Early adoption was strong, with $4.6 billion of inflows in the first month, before flows turned more volatile. Notable milestones cited by market trackers include: March 2024 when the group reached $10 billion in assets under management; June 2024, the first month of net outflows; October 2024, a return of inflow momentum; and April 2025, the start of the current eight-day streak, the longest since launch.
Industry commentary remains measured on how long the trend can persist. Bloomberg senior ETF analyst Eric Balchunas said consistent inflows over an extended period signal genuine demand rather than purely speculative activity, while other analysts caution that flows can reverse quickly amid volatility, regulatory shifts, or macro shocks.
Beyond price effects, sustained ETF buying is viewed as supportive for the broader crypto ecosystem by adding liquidity, lowering perceived risk, and accelerating product development, including potential Ethereum spot ETFs and options tied to Bitcoin ETFs. Higher Bitcoin prices can also improve miner economics, encouraging investment that strengthens network security.
Overall, the April 23 print adds to evidence that institutional participation is deepening, with capital gravitating toward low-cost, high-liquidity products and established issuers. The data suggests the market is beginning to resemble traditional ETF segments, where a small number of leaders capture the bulk of flows.
