The Bitwise Bitcoin ETF recorded a $24.20 million inflow on September 4, while iShares' IBIT and ETHA funds await a second holdings snapshot to show their daily flows.
XOOMAR Pulse Intelligence
Spot BTC & ETH ETF Flows & Holdings
The Bitwise Bitcoin ETF added 303.88 BTC ($24.20 million computed flow) on Friday, September 4. The iShares Bitcoin and Ethereum trusts, IBIT and ETHA, have yet to post a second daily holdings file, so their flows remain unknown. These are some of the crypto ETF flows tracked by XOOMAR Pulse. This pulse covers only BITB, ETHW, IBIT, and ETHA; it does not show the full US spot-ETF market.
BITB's Friday Inflow
Friday's inflow of $24.20 million for BITB is a solid print. Put it next to the largest positive flow in this stored window, a massive $2.95 billion surge on August 21. The XOOMAR calculation shows the fund has accumulated a net total of 38,020.30 BTC from the start of the tape to this Friday's close.
| Ticker | Issuer | As-of date | Holdings | Computed flow | AUM |
|---|---|---|---|---|---|
| BITB | Bitwise | 2026-09-04 | 38,170.30 BTC | $24.20 million | $3.04 billion |
| ETHW | Bitwise | 2026-09-04 | 112,053.33 ETH | $0.00 | $274.71 million |
| IBIT | iShares (BlackRock) | 2026-09-03 | 784,301.23 BTC | $62.48 billion | |
| ETHA | iShares (BlackRock) | 2026-09-03 | 3,504,887.83 ETH | $8.59 billion |
A blank flow is a first snapshot, not a zero print. this dataset covers only the four tickers shown.
A Rollercoaster Quarter in Three Acts
The BITB tape from August tells a story in three distinct phases, built around computed turning points. First, there was a rapid accumulation that peaked at 38,295.25 BTC on August 28. That phase was marked by net inflows.
The washout arrived on August 31, a Monday, with a single-session outflow of $50.41 million. That drawdown was the largest-magnitude daily move within the stored window. It underscores the volatility inherent in the fund's creation and redemption mechanism during that period. Since that point, the fund has recovered ground, culminating in Friday's $24.20 million inflow. The chronology is captured in the session-by-session table.

| 2026-08-24 Monday |
| 2026-08-28 Friday |
| 2026-08-31 Monday |
| 2026-09-04 Friday |
Looking back over the entire stored tape, BITB flows have totaled over $15 billion. That massive figure sits on top of a net change in holdings of 38,020.30 BTC since the tape's initial entry. This Friday's move continues the trend of recovery following the late-August volatility.
ETHW's Flat Streak Finally Ends
Bitwise's Ethereum fund, ETHW, ran a distinctive dry spell over the last quarter. The tape shows a streak of three consecutive stored sessions with exactly $0.00 computed flow, from August 26 to August 28. That flatline was finally broken on Monday, September 1, with a $3.58 million inflow. Since that point, the next three sessions have again posted zero computed flows, leaving the fund's holdings flat on Friday at 112,053.33 ETH.
iShares Debut: First Snapshots Add Immense Scale
The tape now includes first snapshots for IBIT and ETHA, the iShares trusts. Their holdings files are dated September 3. Because these are initial entries, a computed daily flow cannot be determined. Their scale, however, is noteworthy.
IBIT's debut holdings of 784,301.23 BTC are over 20.5 times the size of BITB's current position. Combined, IBIT and BITB together represent 822,471.52 BTC. On the Ethereum side, ETHA's debut of 3,504,887.83 ETH is a staggering 31.3 times larger than ETHW's stash. Together, they hold 3,616,941.16 ETH. The presence of these giants on the tape resets the scale for ETF flows.
How These Numbers Are Made
Holdings are taken directly from issuer public files and snapshotted with their as-of dates. The computed flow shown is the change in the number of coins versus the prior stored row for that ticker, multiplied by the XOOMAR mark at the moment of ingest. AUM is similarly calculated as holdings multiplied by that same mark. When a fund appears for the first time in the tape, there's no prior row, so flow is absent.
Marks Fingerprint, Not a Pressure Gauge
A separate funding rates tape provides context for the marks used in these ETF flow calculations. Do not claim ETF flows caused these funding rates; they are two Pulse tapes timestamped together.
| BTC and ETH marks and funding | | :--- | :--- | :--- | :--- | :--- | | Asset | Exchange | Mark | Funding rate | Open interest notional | | BTC | binance | $79,664.18 | 0.00003226 | not available | | ETH | binance | $2,451.72 | 0.00002735 | not available | | BTC | bybit | $79,663.32 | -0.00002998 | $4.42 billion | | ETH | bybit | $2,451.74 | 0.00001831 | $1.81 billion |
What's Next for the Big Two
The immediate next step for iShares' products is straightforward: a second holdings file. When IBIT and ETHA post a new snapshot with a different as-of date, the tape will compute their flows for the first time. That's the unlock. Until then, their scale is a frozen giant, a debut without motion. For BITB and ETHW, Friday's action is on the tape. The narrative moves with the next issuer update.
