Against the Tape
Wednesday's 8.36 million dollar inflow is modest when sized against BITB's historical activity. It doesn't approach the largest positive flow in the stored window. That title belongs to an astonishing 2.95 billion dollar inflow recorded on August 21. The magnitude of that single day is so vast it defines the fund's journey, dwarfing every other daily move.
The latest event brings BITB's holdings to 37,812.15 BTC, valuing its assets under management at 2.91 billion dollars.
BITB's Three Regimes
The fund's history in this window breaks cleanly into three phases. The first was a steady climb, an accumulation phase where holdings rose to a peak of 38,295.25 BTC on August 28. That peak was immediately followed by a washout period, defined by the massive 2.95 billion dollar flow on August 21 (the largest inflow). Since then, the fund has been in a recovery regime, working its way back from a 50.41 million dollar outflow on August 31 with the smaller, positive flows seen this week. The table below shows every stored session.
| Date | Weekday | 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 |
| ... | ... | ... | ... | ... |

Ethereum Fund Holds Steady
Bitwise's Ethereum fund (ETHW) posted a computed flow of 0.00 dollars on Wednesday. This marked the second stored session in a row with a zero print. Its holdings remained unchanged at 112,053.33 ETH. This two-session streak of zero flows follows two inflows in late August, one for 3.58 million dollars on September 1 and another for 1.39 million dollars on August 28.
Taken over the fund's entire history, its holdings have increased by a net 108,775.33 ETH from its first snapshot to the most recent.
The Wait for iShares
The other major holdings snapshot comes from iShares (BlackRock). Its IBIT Bitcoin ETF and ETHA Ethereum ETF both show their first stored snapshot dated September 1 in this dataset. Because there is no prior row stored for them, their daily flow cannot be calculated and remains unknown. Until a second holdings file appears, their daily pulse is frozen.
Their sheer scale, however, is immense. IBIT's first holdings snapshot is 777,235.18 BTC. That's 20.6 times the size of BITB. ETHA's first snapshot is 3,498,552.07 ETH, which is 31.2 times larger than ETHW. As a pair, they dominate the landscape. Combined, the two Bitcoin funds in this dataset hold 815,047.33 BTC. The two Ethereum funds hold 3,610,605.41 ETH.
IBIT's holdings were valued at 59.84 billion dollars at the time of its snapshot, while ETHA's holdings were worth 8.32 billion dollars.
Computed Flow: How We Know the Numbers
XOOMAR's computed flow figure is derived from issuer public data. For BITB and ETHW, holdings are pulled from embedded fund-page baskets. For IBIT and ETHA, the source is the latest-holdings file from iShares. The flow is the change in the coin count versus the prior stored row for that ticker, multiplied by the XOOMAR mark at the moment of ingestion. A missing flow means it's a first snapshot, not a zero-trade day.
Context from Perpetual Markets
Concurrent price marks from perpetual futures markets provide context for the AUM valuations used in the flow calculation. Please note these are two separate Pulse tapes published together. No causation between ETF flows and these derivatives marks is implied or computed.
| Asset | Exchange | Mark | Funding Rate | |---|---|---|---|---| | BTC | binance | 77,023.60 | 0.00004728 | | ETH | bybit | 2,378.67 | 0.00010000 | | ETH | binance | 2,378.64 | 0.00008965 | | BTC | bybit | 77,023.06 | 0.00006675 |
The Key Is a Second Row
The current picture for Bitcoin ETF flows is split. BITB and ETHW provide a daily pulse. The iShares giants are a snapshot in time. The real story for IBIT and ETHA begins when their next holdings file arrives. That second row will create the first delta that can be multiplied by a mark, unlocking the first view of where the immense weight of those funds is actually moving.
