Bitwise's Bitcoin ETF added 37.99 coins on Tuesday, a $2.99 million inflow that pushes its hoard past 37,900 BTC for the first time. That move lifts the fund's assets under management to $2.98 billion, according to the latest issuer files tracked here and here.

BITB's Tuesday Inflow at $2.99 Million
The Tuesday print, recorded at $2.99 million, sits at the more modest end of the fund's historical swings. It's a step down in magnitude from the largest single-day positive flow in the tape, a $2.95 billion surge that arrived on 2026-08-21. That single event remains the tape's largest-magnitude swing overall.
Three Regimes Shape The Fund
The BITB story from its first stored session splits into three clear phases. The computed bitb-regimes labels them: accumulation into a peak of 37,909.95 BTC on 2026-08-25, a washout around the massive $2.95 billion flow, and a recovery leading into that same final date. Don't read causality into the sequence. The tape just logs the numbers.
| Date | Holdings | Flow | AUM |
|---|---|---|---|
| 2024-01-11 Thursday | 150.00 BTC | $7.80 million | $93.60 million |
| 2024-01-12 Friday | 151.00 BTC | $7.85 million | $94.22 million |
| ... | ... | ... | ... |
| 2026-08-24 Monday | 37,871.97 BTC | $9.40 million | $2.98 billion |
| 2026-08-25 Tuesday | 37,909.95 BTC | $2.99 million | $2.98 billion |
This is a condensed view. The complete session-by-session data for this stored window shows hundreds of entries.
ETHW Sees Back-to-Back Inflows
The Ether-focused ETF from Bitwise saw its own action. The computed ethw-zero-sessions shows its longest stretch of precisely zero flow was zero stored sessions. That means a true zero-flow streak was never recorded. Instead, ETHW posted two consecutive inflows, culminating in an $873,976.13 net addition on 2026-08-25. Its stash now stands at 109,995.14 ETH. The tape doesn't store a forecast, so there's no beat or miss to evaluate.
BlackRock's First Snapshots Show Scale
Newcomers IBIT and ETHA, from iShares (BlackRock), offer first stored snapshots that throw the size of the market into sharp relief. IBIT's initial report shows 768,039.87 BTC, which dwarfs BITB's holdings by a factor of 20.3. Similarly, ETHA's 3,281,903.04 ETH is 29.8 times larger than ETHW's pile. Combined, the two Bitwise funds and the two iShares funds now represent 805,949.82 BTC and 3,391,898.18 ETH in tracked ETF coffers. Because these are first snapshots, daily flow figures are not stored. This isn't a zero print. It's simply the starting line.
How Flow Is Computed
Flow figures are derived from public issuer disclosures. XOOMAR takes the difference in coin holdings between the latest stored row and the previous one for each ticker, then multiplies that delta by the prevailing XOOMAR Bitcoin or Ether mark at the moment of data ingestion. The result is the dollar-denominated "computed flow" shown. This method isolates the implied net dollar movement from the change in the ETF's underlying basket. It's not the perpetual futures funding rate displayed in a separate tape.
Same-Time Marks and Funding
Here are the asset marks taken around the same time as the ETF print. A caution: these are not caused by the ETF flows; they are two separate Pulse tapes timestamped together.
| Asset | Exchange | Mark | Funding Rate |
|---|---|---|---|
| BTC | binance | $78,617.00 | 0.00008772 |
| BTC | bybit | $78,617.00 | -0.00000191 |
| ETH | bybit | $2,444.48 | -0.00001451 |
| ETH | binance | $2,444.52 | 0.00002530 |
Table: Four Funds' Holdings and Flow
Below is the current state for the four tickers tracked in this dataset. A blank flow cell means it's the first available snapshot from the issuer, not a day of zero trading.
| Ticker | Issuer | As-of date | Holdings | Computed flow | AUM |
|---|---|---|---|---|---|
| BITB | Bitwise | 2026-08-25 | 37,909.95 BTC | $2.99 million | $2.98 billion |
| ETHW | Bitwise | 2026-08-25 | 109,995.14 ETH | $873,976.13 | $268.86 million |
| IBIT | iShares (BlackRock) | 2026-08-24 | 768,039.87 BTC | $60.36 billion | |
| ETHA | iShares (BlackRock) | 2026-08-24 | 3,281,903.04 ETH | $8.02 billion |
What Awaits The Next File
The unknowns section of the dataset highlights what's not yet visible. Daily flow for IBIT and ETHA is the most immediate gap; it remains absent until a second holdings file arrives from the issuer. The mechanics behind BITB's 37.99 coin addition are also unclear. It could be net creations, a mix of creations and redemptions, or a pricing artifact. The tape captures only the final result: the delta in holdings multiplied by the mark.
