Spot bitcoin funds lost $211.1 million in seventh day of outflows

U.S. spot-bitcoin exchange-traded products recorded an estimated $211.1 million of net outflows during the September 5, 2024 securities session, according to Farside Investors’ fund-level table. A separate SoSoValue total reported by The Block was $211.15 million. The $50,000 difference is consistent with Farside’s display rounding to one decimal place in millions.

The session extended the group’s negative run to seven consecutive U.S. trading days. Using Farside’s rounded daily totals from August 27 through September 5—and excluding the September 2 Labor Day market holiday—Coinburn calculates cumulative net outflows of $1.0159 billion.

That was a consequential reversal in the regulated channel created after the Securities and Exchange Commission approved exchange rule changes for spot-bitcoin products on January 10, 2024. The September 5 result did not establish who redeemed shares, why they did so or whether fund activity caused bitcoin’s concurrent weakness. It did show that withdrawals were no longer confined to one isolated session.

Fidelity led a session with no recorded inflows

Farside attributed $149.5 million of the September 5 outflow to Fidelity’s Wise Origin Bitcoin Fund, ticker FBTC. Bitwise’s Bitcoin ETF, BITB, lost $30 million; Grayscale Bitcoin Trust, GBTC, lost $23.2 million; and Grayscale Bitcoin Mini Trust, ticker BTC, lost $8.4 million. The other products in Farside’s table showed zero or no positive flow.

Those four rounded entries sum to $211.1 million. FBTC therefore represented about 70.8% of the session’s aggregate outflow, a Coinburn calculation based on Farside’s rounded figures. The concentration matters: the category-wide result was negative, but most of the reported movement came from one fund.

September 5 also followed a $287.8 million net outflow on September 3 and a $37.2 million net outflow on September 4. The sequence began with Farside totals of $127.1 million on August 27, $105.3 million on August 28, $71.8 million on August 29 and $175.6 million on August 30. September 2 was not counted as a trading session because U.S. exchanges were closed for Labor Day.

What the flow numbers measure

The figures are estimates of daily net fund flows compiled at the product level. They are not ETF share-trading volume: secondary-market shares can change hands without creating or redeeming fund shares. They also are not a timestamped measure of bitcoin sold on crypto exchanges. Authorized participants, fund processes, inventory and settlement timing can separate the reported fund flow from any underlying bitcoin transaction.

The source record has another limitation. Farside publishes values rounded to the nearest $100,000, while the contemporaneous SoSoValue-based report supplied a more precise aggregate. Coinburn used one internally consistent Farside series for the seven-session calculation rather than mixing provider totals. The resulting $1.0159 billion is therefore a sum of rounded observations, not an exact accounting figure.

Why the streak mattered

By September 2024, the U.S. products had made demand for bitcoin exposure visible through familiar brokerage infrastructure. The SEC’s January 10 approval allowed listing and trading of the shares but did not approve or endorse bitcoin itself. Daily flow estimates consequently became a useful institutional-market signal, though not a complete map of investor demand.

The defensible conclusion for September 5 is narrow: the regulated U.S. spot-bitcoin product group experienced a seventh straight negative trading session, the estimated outflow exceeded $200 million, and the rounded cumulative loss since August 27 crossed $1 billion. The record did not identify investor type, demonstrate panic selling, establish a consolidated global bitcoin price or prove causation between redemptions and the spot market. Those uncertainties limit interpretation, but they do not erase the scale or persistence of the documented fund-flow reversal.
