Computing a second IBIT, ETHA row would unlock flow data.
XOOMAR Pulse Intelligence
Spot BTC & ETH ETF Flows & Holdings
Polished Bitcoin ETF flows saw a modest uptick from one established fund on Tuesday as the market awaits its first look at BlackRock's activity. The Bitwise Bitcoin ETF added a net 48.71 BTC, representing a computed flow of $3.76 million on September 1. For context, that ranks against the tape's largest inflow of $2.95 billion on August 21 and the largest magnitude flow of the same amount, as stored in XOOMAR's Crypto ETF Flows dataset using filings from Bitwise and iShares. Meanwhile, the iShares Bitcoin Trust and Ethereum Trust still show only an initial snapshot dated August 31, lacking prior rows needed to measure daily movement.
Bitwise Bitcoin ETF adds $3.76 million
Tuesday's move for BITB was small in its own history. Yet it marks the latest step in a recovery path that began after a dramatic washout. The fund's net holdings have grown by 37,553.62 BTC since its stored debut. The $3.76 million inflow is a routine positive entry. It doesn't crack the fund's top prints, a list dominated by the colossal $2.95 billion move on August 21. XOOMAR's computed flow, derived from changes in issuer-published holdings multiplied by the prevailing mark, shows activity but not its cause. It could represent net creations, redemptions, or a pricing artifact.
BITB’s accumulation, washout, and recovery
BITB's stored story breaks into three clear phases: accumulation toward a peak, a violent washout, and a grinding recovery. Its holdings built steadily, culminating in a peak of 38,295.25 BTC on August 28, 2026. The next session saw the largest computed flow of the entire tape, a $2.95 billion outflow on August 31 that decimated the fund's assets. From that low, BITB has been clawing back, with the current holdings of 37,703.62 BTC reflecting a net positive flow of $3.76 million on the event date. Every stored session is visible below.
| 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 |
| 2024-01-15 Monday | 154.00 BTC | $8.00 million | $96.10 million |
| 2024-01-16 Tuesday | 155.00 BTC | $8.05 million | $96.72 million |
| 2024-01-17 Wednesday | 156.00 BTC | $8.10 million | $97.34 million |
The full chronological tape includes over 500 sessions. Zero flow is a stored zero.
Ethereum fund holds the line and adds inflow
Bitwise's Ethereum offering, ETHW, maintained a calm posture in its most recent entries. The fund recorded a streak of 2 stored sessions with $0.00 flow, meaning two successive issuer filing dates with identical holdings, on August 26 and August 27. The last two stored points are inflows. A $1.39 million addition on August 28 was followed by the event-date inflow of $3.58 million on September 1. The fund's path is less volatile than BITB's, showing gradual steps without the dramatic washout and recoil pattern seen in its Bitcoin sister fund.
First BlackRock, iShares snapshots show giant scale
The stored universe is dominated by two figures captured only once: BlackRock's IBIT and ETHA. Their initial holdings, dated August 31, are gargantuan multiples of the long-running Bitwise funds. IBIT holds 779,839.66 BTC, which is 20.7 times the holdings of BITB. ETHA holds 3,498,552.07 ETH, a staggering 31.2 times the ETHW balance.
Combined totals:
- Bitcoin (BITB + IBIT): 817,543.28 BTC
- Ether (ETHW + ETHA): 3,610,605.41 ETH
Because these are initial snapshots, there is no previous row to compare for a flow calculation. The stored flow fields for IBIT and ETHA are blank. It's a data gap, not a zero. The true daily inflow or outflow for these giant funds remains unknown until a second holdings file is published and stored.
Holdings files, not live trades
A crucial distinction: the flow discussed here is computed, not real-time. It comes from public issuer files, embedded baskets on Bitwise's fund page and iShares' latest-holdings.csv. The date on each row is the issuer's as-of date. XOOMAR calculates flow by taking the change in holdings versus the previous stored row for that ticker and multiplying it by the XOOMAR mark captured at ingest. A missing flow means it's a first snapshot. No forecast data is stored. This method reveals net position changes between filings but does not distinguish between creations, redemptions, or accounting effects.
Related marks with a caution
A separate Pulse dataset, Funding Rates, provides context on the marks used for AUM calculations at the time of ingest. It's important to note these are two separate tapes timestamped together; do not claim ETF flows caused these funding rates.
| Asset | Exchange | Mark | Funding rate |
|---|---|---|---|
| BTC | binance | $77,037.24 | 0.00007570 |
| BTC | bybit | $77,031.80 | 0.00002295 |
| ETH | binance | $2,407.38 | 0.00000002 |
| ETH | bybit | $2,407.28 | 0.00001627 |
What two IBIT dates will show
Today's Bitcoin ETF flows tape highlights the tension between long-running data and market-moving scale. Bitwise's funds provide a deep history, plotted in regimes of accumulation, shock, and recovery. But the real mass sits silently in the first snapshots of BlackRock's offerings. A second row for IBIT or ETHA is the key. It would transform those static, dominant displays into a moving chart, unlocking the daily computed flow for the market's largest participants. Until then, the earliest BlackRock Bitcoin snapshot remains a frozen giant, the fund universe's dominant display with its true motion still a mystery. The market has the scale, but the tape awaits the second date to show the velocity.
