Key Takeaways
- • US spot Bitcoin ETFs recorded a net outflow of about $643 million on Friday, October 30, 2026, their largest one-day exit since June 25 and the 12th largest since the funds began trading in January 2024, according to CoinDesk citing market data.
- • The outflow erased roughly 64 percent of the funds' just over $1 billion net inflow for 2026, pushing total assets to about $98 billion, below the $100 billion level traders watch.
- • MSCI will publish its final list of affected "non-operating companies" on November 11, with changes taking effect at the November 30 market close; Strategy Inc., holding about 848,000 BTC, accounts for most of the potential deletions by size at roughly $40 billion of float-adjusted value.
- • Index removal would not by itself force Strategy to sell Bitcoin, but could trigger passive selling of about 13 million shares, roughly 3.1 percent of its shares, per Strategy's own estimate.
- • Market participants cited a Binance security incident with about $6.3 billion in estimated financial impact, attributed by the FBI to North Korean hackers, as a factor behind the outflows.
Summary
US spot Bitcoin ETFs lost about $643 million on Friday, October 30, 2026, according to CoinDesk, citing market data. The outflow was the largest single-day exit since June 25, when outflows reached roughly $696 million. Reported fund-level figures show BlackRock's IBIT at about $234 million of outflows and Fidelity's FBTC at about $201 million, with ARK 21Shares' ARKB near $130 million, Grayscale's GBTC near $53 million and Bitwise's BITB near $26 million. Ether ETFs also lost roughly $156 million that day, according to one aggregator. Spot Bitcoin ETFs had posted a net inflow of just over $1 billion for 2026 before the outflow, which erased about 64 percent of that total. Total fund assets fell to about $98 billion. For October as a whole, one report put net flows at roughly negative $516 million, even though IBIT gained about $932 million over the month, suggesting demand is uneven across products.
Several factors were cited for the selling. Binance estimated the financial impact of a security incident at about $6.3 billion, said user funds were safe and that losses would be covered from its own reserves, and temporarily paused deposits and withdrawals. The FBI attributed the activity to North Korean hackers. A derivatives firm told CoinDesk that traders rushed to protect themselves. Separately, a negative Coinbase premium suggested weaker US buying, and the Crypto Fear and Greed Index sat in the low 30s. Bitcoin traded around the mid-$70,000s in early November. Markets also faced the November 3 US midterm elections and the November 6 US jobs report.
The second focus is MSCI's treatment of companies that mostly hold one asset. On October 15, 2026, MSCI announced results of its consultation on "non-operating companies" in its Global Investable Market Indexes. Companies first face a core screen for substantial operating assets, then are tested against five financial ratios and flagged as ineligible if they fail four or more. Current members are removed only if they fail in each of their two most recent annual filing periods. MSCI's potential-impact list named five possible deletions: Strategy (formerly MicroStrategy), Metaplanet, Yellow Cake, Skel Fjarfestingafelag and Upexi. Strategy accounts for most of the list by size. The company argues its Bitcoin business is an operating segment and that the rule treats digital asset treasury companies unfairly; chair Michael Saylor has called the rule discriminatory.
The mechanics matter for allocators. Index-tracking funds must sell a stock when it leaves an index. Strategy estimates, in its own calculation rather than an MSCI figure, that index-linked funds hold about 13 million shares, equal to about 60 percent of its 30-day average daily trading volume. Removal would not force Bitcoin sales, which remain a separate board decision, but a lower premium to net asset value could shrink Strategy's ability to raise capital for further purchases. MSCI will publish its final list on November 11, and changes take effect at the November 30 market close. The outcome was not known at the time of writing.
