Deep Dive
1. Todays Tally
The freshest daily snapshot shared today shows Bitcoin ETFs at roughly ?2,061 BTC, or ?$183.86M, with the fund-level split still to come later in the day as issuers and trackers finalize data daily flows update.
Data vendors and observers typically post aggregate figures first, then per?issuer tables once creations and redemptions are reconciled. Intraday prints can be revised as late filers come in.
If you need exact leaders today, wait for the per?fund table later; early reads are directionally useful but incomplete.
2. Where Leadership Usually Sits
Flows have been concentrated in iShares Bitcoin Trust (IBIT), which dominated 2025 with over $25 billion of inflows, while Grayscale products often anchor the other side of the ledger due to ongoing redemptions IBIT dominance.
This concentration means the leader on any given day is frequently IBIT on the inflow side and a Grayscale vehicle on outflow days. Smaller issuers can occasionally top the table on quieter sessions.
When the per?fund table drops, check IBIT first for direction and GBTC or BTC (Grayscale Mini) for the largest offsetting outflows.
3. Last Per?Fund Leaders Posted
The latest detailed per?ETF breakdown available is for 31 Dec. It showed outflows led by iShares Bitcoin Trust (IBIT, about $99.04M), followed by ARK 21Shares Bitcoin ETF (ARKB, about $76.53M), Grayscale Bitcoin Trust (GBTC, about $69.09M) and Fidelity Wise Origin Bitcoin Fund (FBTC, about $66.58M) per-ETF list.
While that was a year?end session, it illustrates the typical concentration pattern in leaders and laggards across issuers.
If today also skews risk?off, expect a similar pattern where IBIT and one or two large peers explain most of the net move.
Conclusion
The best current read is that US Bitcoin ETFs are net negative today on preliminary figures, with the fund?by?fund leaderboard not yet posted. Leadership typically clusters in IBIT on inflows and Grayscale products on outflows. Once the per?issuer table updates later, the days leaders should mirror that concentration pattern unless an unusually large creation or redemption hits a smaller fund.
