U.S. spot bitcoin funds capped a $3.06 billion inflow week

By April 26, 2025, the completed U.S. trading week showed a sharp return of demand for spot bitcoin exchange-traded products. Farside Investors’ fund-flow table recorded $3.0629 billion of net inflows across the five sessions from April 21 through April 25. Every session was positive: $387.4 million, $936.5 million, $917.0 million, $442.0 million and $380.0 million, respectively.

That sequence mattered more than any single daily print. It showed that regulated brokerage wrappers had again become a large channel for bitcoin exposure after an unsettled start to April. A contemporaneous report by The Block described the total as the strongest weekly inflow since November 2024 and the second-largest weekly result then on record. Those rankings are the publication’s characterization of the dataset, not a claim that fund demand alone caused bitcoin’s move.

Where the money concentrated

BlackRock’s iShares Bitcoin Trust ETF, IBIT, accounted for $1.4457 billion of the five-day total, according to a Coinburn calculation from Farside’s daily table. That was 47.2% of the aggregate. ARK 21Shares Bitcoin ETF, ARKB, contributed $621.1 million, while Fidelity Wise Origin Bitcoin Fund, FBTC, contributed $573.8 million. The remaining net amount was spread among the other listed products after fund-level inflows and redemptions were offset.

The structure behind those numbers was already established. The Securities and Exchange Commission had approved exchange rule changes for multiple spot bitcoin exchange-traded products on January 10, 2024. The products gave investors exchange-traded price exposure without requiring them to operate a wallet or hold private keys directly. They were securities trading on regulated venues, but the SEC’s approval of their listing was not an endorsement of bitcoin and did not remove bitcoin-market risk.

Flow data also require careful reading. “Net inflow” means estimated creations less redemptions in dollar terms for the specified product and session. It is not the same as trading volume, assets under management or a verified on-chain purchase made at one moment. Farside compiles the figures from fund data, and historical entries can be corrected. Summing rounded daily figures produces the $3.0629 billion total; it should not be read as precision beyond the reported $0.1 million units.

Price rose with the flow reversal

A third-party aggregated historical series carried by StatMuse records bitcoin at an $85,174.30 daily close on April 20 and a $94,646.93 close on April 26. On that series, the change was 11.1% over the six-day interval. The April 26 observation also shows a $95,251.36 high and a $93,927.25 low.

Those values are dataset-specific. Bitcoin trades continuously across venues, so there is no single official global close, and another exchange or cutoff can produce different open, high, low and close values. The comparison establishes contemporaneous direction and scale; it does not establish that ETF creations caused the appreciation. Price gains can themselves attract allocations, while macroeconomic news, positioning and liquidations can influence both price and flows.

What April 26 established

The defensible conclusion on April 26 was narrower than a declaration of a new bull market. U.S. spot bitcoin products had just completed five consecutive positive sessions, with unusually large net creations concentrated in three funds, while bitcoin’s aggregated dollar price had advanced materially over the same calendar stretch.

That combination demonstrated the institutional access channel was active and capable of absorbing billions of dollars in a week. It did not reveal the identity or motives of end investors, separate long-only allocations from arbitrage trades, or guarantee that the flow pattern would continue after April 26, 2025.
