BlackRock ETFs Go Full Tsunami While Holders Swim 22% in the Red 🏊

BlackRock's spot Bitcoin ETF pulled in $273.2 million in net inflows over two sessions after clients shed $63.6 million earlier in the same week, according to Arkham on-chain data that reconciles to the dollar with reported fund creations. The reversal made the iShares Bitcoin Trust (IBIT) effectively the entire U.S. spot Bitcoin ETF market for the July 27 to July 30 window, with the 13-fund complex posting a combined net inflow of $203.9 million over the four sessions. On July 30 alone, IBIT contributed $183.38 million of the $233.13 million in creations, or 79% of the day's total and the largest single-day inflow since July 6, according to Farside Investors and SoSoValue data.

The buying arrives with the average U.S. spot Bitcoin ETF investor sitting on paper losses of roughly 22%. Research firm Hedgeye cited Bloomberg Intelligence figures on July 28 showing an aggregate gross cost basis of $82,249 across all spot Bitcoin ETF purchases, measured against a marked price of $64,114. Bitcoin ($BTC) traded around $62,907 on Friday, down 2.96% over 24 hours, which widens the gap to about 24%. Aggregate unrealized losses reached $16.33 billion as of July 20, swinging from a peak unrealized gain of $86.32 billion recorded on October 6, 2025, the day $BTC hit its $126,080 all-time high.

IBIT share creations reflect authorized participant demand rather than proprietary positioning by BlackRock, with creations forcing purchases of $BTC and redemptions forcing sales. IBIT has led flows in both directions during July, absorbing $202.5 million and $212.2 million of outflows on July 23 and July 24, the two worst sessions of the month. Trust holdings peaked near 823,000 $BTC in mid-May, declined by roughly 90,000 $BTC through early July, and have since flattened near 730,000 $BTC.
