Bitwise's Bitcoin spot ETF BITB saw its holdings rise by 119.39 BTC on Monday, August 24, equal to a computed inflow of $9.40 million. This modest flow arrives alongside a foundational shift: the first holdings snapshots for BlackRock's massive iShares Bitcoin and Ethereum funds, IBIT and ETHA, dated August 21. These funds dominate the landscape but have no prior stored sessions for flow comparison. For a complete picture of the daily Bitcoin ETF flows, see the Crypto ETF Flows hub and its API.

Spot BTC & ETH ETF Flows & Holdings
Monday's Action
BITB's addition lifted its holdings to 37,871.97 BTC ($2.98 billion AUM) as of August 24. This $9.40 million inflow is a routine print compared to the fund's stored history. XOOMAR reading places it far from the largest positive flow in the tape: a $2.95 billion print dated August 21. Measured by sheer magnitude, the same $2.95 billion event also holds the record.
BITB's Stored Journey
BITB's story in this window divides into three distinct phases while climbing to a peak holding of 37,871.97 BTC on August 24, 2026. The recovery phase, defined by an ultimate flow value matching the peak asset value of $2.95 billion, leads directly into the August 24 entry with its $9.40 million inflow.
The full chronological tape below shows the progression.
| Date | Holdings | Flow | AUM |
|---|---|---|---|
| 2024-01-11 | 150.00 BTC | $7.80 million | $93.60 million |
| 2024-01-12 | 151.00 BTC | $7.85 million | $94.22 million |
| 2024-01-15 | 154.00 BTC | $8.00 million | $96.10 million |
| ... | ... | ... | ... |
| 2026-08-21 | 37,752.58 BTC | $2.95 billion | $2.96 billion |
| 2026-08-24 | 37,871.97 BTC | $9.40 million | $2.98 billion |
Table: BITB holdings and flow, every stored session. Zero flow is a stored zero, not a missing row.
Ethereum ETF: Bitwise's Turnaround
Bitwise's Ethereum ETF, ETHW, also posted a flow on August 24. Its holdings increased by about 930 ETH, translating to a computed inflow of $2.30 million. This marks the second consecutive Monday inflow for ETHW, preceded by a $272.74 million inflow on August 21. The stored record shows the fund never had a session with exactly $0.00 flow.
The New Giants: iShares' First Snapshot
The August 21 data introduces baseline snapshots for two market giants. BlackRock's iShares Bitcoin Trust (IBIT) reported holdings of 765,389.94 BTC, or over 60 times the size of BITB's AUM. Its Ether counterpart ETHA reported 3,245,090.15 ETH, a figure nearly 30 times larger than ETHW. Together, the iShares products hold 803,261.91 BTC and 3,354,727.74 ETH across both asset classes.
Because these are first snapshots, the table shows a blank flow column. Daily flow for IBIT and ETHA is not stored in this dataset, and no prior row exists for comparison.
| Ticker | Issuer | As-of date | Holdings | Computed flow | AUM |
|---|---|---|---|---|---|
| BITB | Bitwise | 2026-08-24 | 37,871.97 BTC | $9.40 million | $2.98 billion |
| ETHW | Bitwise | 2026-08-24 | 109,637.59 ETH | $2.30 million | $271.54 million |
| IBIT | BlackRock (iShares) | 2026-08-21 | 765,389.94 BTC | $60.26 billion | |
| ETHA | BlackRock (iShares) | 2026-08-21 | 3,245,090.15 ETH | $8.04 billion |

How the Tape is Made
These flow figures are computed from issuer public files. For BITB and ETHW, holdings come from Bitwise's fund-page embedded baskets. For IBIT and ETHA, holdings are pulled from iShares' latest-holdings.csv. The date on each row is the issuer's as of date. Computed flow is the change in holdings versus the previous stored row for that ticker, multiplied by the XOOMAR mark at ingest. A first snapshot has no previous row, so flow is absent. This analysis cannot determine whether the BITB addition was driven by creations, redemptions, or a pricing artifact. The tape only shows ฮ holdings ร mark.
Context from the Perpetual Markets
At the time of ingest, perpetual futures markets quoted Bitcoin around $78,790 and Ethereum near $2,479. This parallel market data from Funding Rates provides context for the ETF AUM calculations. It's crucial to note that no causation should be inferred; these are two separate Pulse tapes timestamped together.
What a Second File Would Show
With a second holdings file for IBIT or ETHA, the flow columns would unlock. Their sheer size means even modest daily percentage changes could translate to dollar flows that dwarf typical prints from other funds. Until then, these giants move in silence, their scale only visible as a snapshot.
Tracking Bitcoin ETF flows requires looking beyond single-day prints to the structural shifts in market participation. The addition of BlackRock's titans reshapes the baseline, while established funds like BITB continue their own stored journeys. The next movement to watch is the first computed flow for IBIT or ETHA, which will finally quantify the daily appetite moving through the industry's largest conduits.
