SEC filings show a $17.4 billion BlackRock crypto reversal as mystery investors redeem 106,000 BTC

BlackRock’s crypto ETFs moved from a $13.9 billion Q2 increase to a $3.5 billion decrease, while positive August sessions remain inconclusive.

Quick Take

  1. BlackRock’s spot Bitcoin and Ethereum ETFs saw a $3.5 billion net capital-share decrease in Q2, after a $13.9 billion gain a year earlier.
  2. That swing reflects share creations and redemptions, not market prices, and it hit IBIT and ETHA trust-level activity directly.
  3. August inflows offered a small offset, but the filings suggest only sustained buying will show whether redemptions have eased.

BlackRock’s spot Bitcoin and Ethereum ETFs recorded a combined $3.5 billion net decrease from capital-share transactions in the second quarter, reversing a $13.9 billion increase a year earlier, according to new SEC filings.

The $17.4 billion year-over-year swing measures trust-level share creation and redemption activity.

The Aug. 6 filings for the iShares Bitcoin Trust ETF (IBIT) and iShares Ethereum Trust ETF (ETHA) use the capital-share line for contributions tied to issued shares less distributions tied to redeemed shares. It is separate from price-driven changes in the trusts’ net assets and investors’ individual profits or losses.

IBIT recorded $4.3 billion of contributions for shares issued and $7.2 billion of distributions for shares redeemed during the three months ended June 30. The difference produced a $2.9 billion net decrease.

ETHA recorded $943.3 million in contributions and $1.5 billion in distributions, resulting in a $583.4 million decrease.

The 2025 IBIT filing and 2025 ETHA filing show the combined $13.9 billion prior-year increase, creating a $3.5 billion decrease against this year.

BlackRock’s IBIT and ETHA shifted from a $13.9 billion capital-share increase in Q2 2025 to a $3.5 billion decrease in Q2 2026.

The activity tables placed 106,148 BTC and 770,839 ETH in rows labeled as assets sold for share redemptions. The footnotes say those rows include in-kind distributions valued at $3.85 billion of Bitcoin and $904 million of Ethereum, without disclosing the unit-level split.

The full token quantities cannot be treated as wholly open-market sales, and the filings do not identify who initiated the underlying share redemptions.

As a nominal scale marker only, $562.3 million equals 15.9% of $3.5 billion. If August sustains the same $187.4 million combined daily average, it would take about 19 trading sessions for BlackRock funds to accumulate a similar amount.

That shows why persistence over weeks is the more meaningful test.
