U.S. spot bitcoin funds drew $908.1 million in strongest inflow since November

U.S.-listed spot bitcoin funds recorded an estimated $908.1 million of aggregate net inflows on January 3, 2025, reversing the group’s $242.3 million net outflow on January 2. The January 3 total was the largest daily inflow since November 21, 2024, according to Farside Investors’ fund-flow dataset.

The reversal mattered because it showed that demand through regulated securities products could change sharply between consecutive sessions. Less than one year after the funds began trading, the January 3 result demonstrated that their daily creations and redemptions had become a material part of bitcoin’s institutional market context. It did not, by itself, prove a durable change in investor sentiment or establish what bitcoin would do next.

Four funds accounted for nearly all of the estimate

Farside attributed $357.0 million of the January 3 inflow to Fidelity’s Wise Origin Bitcoin Fund, or FBTC. BlackRock’s iShares Bitcoin Trust, IBIT, followed with $253.1 million, while the ARK 21Shares Bitcoin ETF, ARKB, recorded $222.6 million and Bitwise’s BITB recorded $61.1 million.

Those four estimates sum to $893.8 million, approximately 98.4% of the $908.1 million group total. VanEck’s HODL added an estimated $5.6 million and the Grayscale Bitcoin Mini Trust added $8.7 million. Farside recorded zero net flow for the remaining products in its table.

The January 3 total exceeded the absolute value of the January 2 outflow by $665.8 million. The larger session-to-session swing was $1.1504 billion, calculated by comparing negative $242.3 million with positive $908.1 million. These are Coinburn calculations from Farside’s figures, not separately reported fund statistics.

ETF.com subsequently reported the same $908.1 million group total and the same four leading funds. Another specialist publication, citing SoSoValue, independently placed the session near $908 million and also identified Fidelity, BlackRock and ARK products as the principal contributors.

Bitcoin advanced, but causation is unverified

Coinbase Exchange’s BTC-USD market opened its January 3 UTC candle at $96,905.48 and closed it at $98,136.51. That represents an open-to-close increase of approximately 1.2703%. The same candle recorded a low of $96,016.63, a high of $98,969.92 and volume of 9,021.88538159 BTC.

Those measurements apply only to Coinbase’s BTC-USD instrument during the 24-hour window beginning at 00:00 UTC on January 3. Bitcoin trades continuously across venues, so the Coinbase close is not a consolidated global closing auction. Coinbase also cautions that historical candle data can be incomplete where an interval contains no trading ticks.

The contemporaneous records do not isolate the ETF flows as the cause of the price increase. Fund subscriptions, broader risk appetite, derivatives positioning, activity on non-U.S. venues and sales by existing holders could all affect bitcoin’s price during the same window.

What the evidence establishes

The SEC’s January 10, 2024 approval order verifies the regulatory foundation for the listed spot products, including funds sponsored by Grayscale, Bitwise, BlackRock, ARK, Fidelity and other issuers. That order establishes what the products were; it does not certify Farside’s January 3, 2025 flow estimates.

The defensible conclusion is narrower: an attributable dataset, corroborated by specialist reporting, recorded the strongest aggregate daily inflow since November 21 and a sharp reversal from January 2. Because the surviving public record does not provide a single audited, issuer-level statement covering every fund, the $908.1 million figure should be understood as a widely cited estimate rather than an official consolidated total.
