Bloomberg Intelligence Senior ETF Analyst Eric Balchunas has flagged new activity in US spot Bitcoin ETFs, though the specific figure and reporting period attached to his update have not been independently verified at the time of publication. The development is being tracked closely given Balchunas’s consistent role as a primary data source for institutional Bitcoin fund flows.
What Eric Balchunas Reported About US Spot Bitcoin ETFs
Balchunas, Senior ETF Analyst at Bloomberg Intelligence, shared an update on US spot Bitcoin ETF activity. Bloomberg Intelligence has been among the most cited sources for ETF flow data since the funds launched following SEC approval in January 2024. The specific metric, flow direction, and dollar value referenced in his latest update are pending verification against a primary data source.

Flow data for US spot Bitcoin ETFs is tracked daily by Farside Investors, which publishes fund-by-fund net inflow and outflow figures across all approved products. Until the underlying Farside or Bloomberg dataset can be cross-referenced, the precise figure in Balchunas’s report should be treated as unconfirmed.

The SEC’s decision to approve higher IBIT options limits earlier this year expanded the hedging toolkit available to institutional participants in the Bitcoin ETF market, a structural change that analysts have linked to sustained professional demand for the products.

How to Read a US Spot Bitcoin ETF Flow Update
Net flow figures measure the difference between new capital entering a fund and redemptions leaving it on a given day or week. A positive net flow indicates more capital entering the product than exiting; a negative figure indicates the reverse. The figure does not directly reflect Bitcoin’s spot price movement, though large sustained inflows tend to require ETF issuers to purchase Bitcoin on the open market to back new shares.
Bloomberg Intelligence has previously covered the pace at which US spot Bitcoin ETFs accumulated assets relative to other ETF launches. Bloomberg’s earlier coverage of spot ETF approval odds gave Balchunas’s team visibility as a consistent source for regulatory and flow-related commentary on these products.
Morgan Stanley’s Bitcoin ETF launch earlier this year added another major issuer to the competitive field that Balchunas’s flow reports cover, broadening the dataset beyond the original cohort of products.
Details That Need Confirmation
Three data points are required before the headline figure can be reported with confidence: the exact ETF metric being cited (net inflows, gross inflows, total assets under management, or trading volume); the applicable reporting period (daily, weekly, or since inception); and whether the number is net or gross. The primary Balchunas post or Bloomberg Intelligence report that carries the figure has not been linked to a verifiable source URL in the current research package.
Readers tracking this story can monitor Farside Investors’ Bitcoin ETF flow table for daily updates, which serves as the most granular publicly available dataset for individual fund performance across all US-listed spot Bitcoin products.
Bitcoin’s network fundamentals remain the baseline against which ETF demand is ultimately measured. Miner-side selling pressure, UTXO age distribution, and exchange reserve levels each provide on-chain context that complements the fund-flow picture Balchunas tracks from the institutional side.
