Bitcoin ETFs Shed $412 Million in a Single Day as IBIT Bleeds $403 Million

U.S. spot Bitcoin exchange-traded funds lost $412 million in net flows on Friday, Nov. 6, with BlackRock's iShares Bitcoin Trust (IBIT) accounting for almost the entire outflow. IBIT alone recorded $403 million in net redemptions — roughly 98 cents of every dollar that left the category that day.

The figure comes from daily fund-flow data, which tracks money entering or leaving through share creations and redemptions. It is worth stating what the number does not mean: these flows do not represent direct Bitcoin purchases for BlackRock's corporate balance sheet. The funds are separate vehicles, and their creation and redemption mechanics are the only things the daily tally measures.

Where did the money move?

Fidelity's FBTC posted the largest daily inflow among the eleven-fund category, drawing $42.8 million. That is a tenth of what IBIT lost, but it kept Fidelity's fund on the positive side of the ledger on a broadly negative day.

Cumulative figures frame the single-day move in proportion:

• IBIT: $65.101 billion in cumulative net inflows since launch
• FBTC: $10.266 billion in cumulative net inflows
• All U.S. spot Bitcoin funds combined: $55.699 billion in cumulative net inflows

The category-wide cumulative number sits below IBIT's own because several funds have suffered net outflows over their lives, offsetting part of the larger funds' gains. A $412 million daily loss equals less than 1% of that cumulative total — a bad day, not a reversal of the category's overall trajectory.

How large are these funds relative to Bitcoin itself?

As of the prepublication snapshot, combined net assets across the spot funds stood at $95.897 billion. That equals 6.28% of Bitcoin's total market capitalization — meaning roughly one dollar in every sixteen of Bitcoin's market value now sits inside U.S. spot ETF wrappers.

That concentration matters for market structure. When nearly a fifth of the category's assets sit in a single fund, as is the case with IBIT, one fund's redemption activity can move the daily flow numbers almost on its own. Friday demonstrated exactly that pattern: strip out IBIT, and the rest of the category was close to flat, with FBTC's $42.8 million inflow largely offsetting the remainder.

What should readers watch next?

Two caveats temper any narrative built on this data. First, daily flows are a snapshot, not a trend — one heavy redemption day at a single issuer does not establish sustained institutional withdrawal. Second, cumulative net inflows remained positive despite Friday's withdrawals, so the category has not tipped into net contraction.

The forward question is whether IBIT's outflow repeats in subsequent sessions or proves to be a one-day event tied to a specific redemption. Sustained multi-day outflows at IBIT's scale — roughly $2 billion per week if Friday's pace held — would begin to erode the category's cumulative position and pressure the funds' share of Bitcoin's market capitalization. Until then, Friday stands as the largest single-fund outflow day for the category in recent sessions, but not yet a change in direction.
