U.S. spot Bitcoin ETFs logged their worst 30-day stretch on record, with $6.35B in net outflows across 582 rolling windows tracked by Galaxy Research since the funds launched in January 2024. The mass exodus — concentrated in BlackRock's IBIT and Fidelity's FBTC — coincided with BTC's 17.4% price decline to ~$64,000. But long-term holders absorbed 125,000 BTC in June, and whale wallets now control 35.82% of available supply, suggesting the ETF panic is being fully absorbed by strong hands.
U.S. spot Bitcoin ETFs logged their worst 30-day stretch on record, with $6.35B in net outflows across 582 rolling windows tracked by Galaxy Research since the funds launched in January 2024. The mass exodus — concentrated in BlackRock's IBIT and Fidelity's FBTC — coincided with BTC's 17.4% price decline to ~$64,000. But long-term holders absorbed 125,000 BTC in June, and whale wallets now control 35.82% of available supply, suggesting the ETF panic is being fully absorbed by strong hands.
Galaxy Research data published June 21, 2026 confirms that U.S. spot Bitcoin ETFs suffered $6.35 billion in net outflows over the trailing 30 trading days — the largest drawdown across all 582 rolling 30-day windows the firm has tracked since the funds launched in January 2024.
The bleeding was most acute during a 13-consecutive-day outflow streak from May 15 through June 3, which alone accounted for approximately $4.4 billion in net redemptions — roughly 59,400 BTC walking out the door. The pain was concentrated in the two largest funds: BlackRock's IBIT and Fidelity's FBTC, which saw peak daily redemptions in the hundreds of millions.
Weekly outflows peaked at $1.72 billion during the week ending June 5, then declined sharply to approximately $226 million last week — an 87% drop. Galaxy Research notes that daily withdrawal figures are still "deepening day over day," though the rate of decline has moderated.
The outflow pushed aggregate net flows since ETF launch down to approximately $53.4 billion, a sharp decline from the October 2025 high-water mark of $63 billion. Bitcoin traded near $64,167 at the time of the report, down 17.4% over the same 30-day window.
The other side: whales are taking it all.
While ETF investors fled, long-term holders absorbed 125,000 BTC in June alone, according to data from Finance Magnates cited by Fortune. Whale wallets now control 35.82% of available Bitcoin supply — the highest concentration on record.
This creates a striking divergence: the same BTC that exited ETF wrappers was almost entirely absorbed by non-ETF accumulators. The 59,400 BTC that left during the 13-day streak represents less than half of the 125,000 BTC that long-term holders added to their positions during the same month.
BlackRock has pushed back against concerns. Jay Jacobs, BlackRock's head of thematic and active ETFs, emphasized that temporary outflows won't alter the firm's strategic Bitcoin outlook. Bernstein maintains its $225,000 year-end price target, and Bitwise CIO Matt Hougan confirmed his $200,000 forecast.
The record outflow also comes amid a broader institutional rotation. Tokenization of real-world assets crossed $20 billion on-chain, driven by deals like Bullish's $4.2B acquisition of Equiniti and Ondo's live settlement with JPMorgan. Capital isn't exiting crypto — it's rotating from plain-vanilla Bitcoin exposure toward yield-bearing and infrastructure plays.
The OCC granted Circle final approval to establish Circle National Trust, a federally supervised national trust bank, placing the world's second-largest stablecoin (USDC, $73.2B) under direct federal banking oversight — with reserve management as a planned future capability.
Morgan Stanley amended SEC filings for its proposed Ethereum (MSSE) and Solana (MSOL) ETFs with a 0.14% management fee — the lowest in crypto ETFs — while offering staking yield (50-80% ETH, up to 100% SOL). Its Bitcoin ETF (MSBT), launched just April 8, already holds $364M.
SWIFT announced its blockchain-based shared ledger is ready for initial use, with 17 Tier 1 banks across six continents preparing to pilot live tokenized deposit transactions. The network — used by 11,500+ financial institutions and moving the equivalent of global GDP every 2-3 days — built the ledger in just nine months, marking the most significant mainstream blockchain deployment by traditional finance infrastructure.
