Deep Dive
1. IBIT Led Weekly Outflows
IBIT posted the largest weekly net redemptions, exceeding $1 billion, placing it at the top of the outflow leaderboard among spot Bitcoin ETFs (weekly summary). IBIT also printed a record single-day outflow of about $523 million earlier in the week (market update).
The largest fund bore the brunt of selling, signaling institutional trimming where liquidity is deepest.
2. GBTC and FBTC Followed
Grayscales GBTC and Fidelitys FBTC saw materially smaller but still notable weekly outflows near $172 million and $116 million (weekly summary). There was some stabilization late week, with FBTC recording a $108 million daily inflow on Friday (same summary).
Secondary outflows concentrated in the next-largest products, but late-week inflows show positioning can quickly swing.
3. Heaviest Day Breakdown
The second-worst single day on record saw about $903 million pulled across US spot Bitcoin ETFs, led by IBIT ($355.5M), GBTC ($199.35M), and FBTC ($190.4M) (The Block). Ether ETFs also bled on the day, with roughly $262 million in outflows reported (daily recap).
Outflows clustered in the largest vehicles, amplifying market stress. Watching whether such extreme single-day moves persist helps gauge near-term risk.
Conclusion
Outflows were concentrated in the biggest Bitcoin ETFs, with IBIT leading and GBTC and FBTC next in line. The pattern reflects risk-off positioning and profit-taking into volatility. If outflows moderate, late-week inflows suggest flows can stabilize quickly; if they persist, pressure on broader crypto beta could continue.
