Today, the outflow of funds from Bitcoin ETFs mainly occurred through the BlackRock fund — IBIT, as well as smaller amounts from Fidelity (FBTC), Grayscale (GBTC), and Bitwise (BITB). The data account for flows after the US trading session; the figures provided correspond to the last reporting day (December 24, UTC).

IBIT led the outflow with approximately $157.34 million according to the daily report.
FBTC (~$15.30 million), GBTC (~$10.28 million), and BITB (~$5.72 million) also showed outflows in the same session according to the update.
Total assets of BTC ETFs remained around $114 billion, providing an idea of the scale and market pressure according to the session’s results.

Details

1. Leader — IBIT

The iShares Bitcoin Trust (IBIT) from BlackRock consistently remains the largest driver of flows; in the latest session, it led the outflow with approximately $157.34 million (session results). Its size and prevalence make IBIT’s daily net flows a reliable indicator of market sentiment for Bitcoin (BTC).

IBIT has accumulated some of the largest historical net inflows among BTC ETFs, so it often dominates daily flow reports (market analysis).

What this means: When IBIT shows large outflows, it usually intensifies short-term pressure on BTC; a return to inflows can quickly weaken this pressure.

2. Secondary outflows

Other major funds also participated in the outflow but in smaller volumes: FBTC (~$15.30 million), GBTC (~$10.28 million), and BITB (~$5.72 million) in the latest session (daily report). These secondary indicators are important for assessing the breadth of the outflow but usually follow the leader — IBIT.

Previous sessions showed similar trends when several funds simultaneously buy back shares, amplifying the overall outflow (session results).

What this means: Mass buybacks across multiple funds reinforce the outflow signal; isolated outflows are less significant if IBIT and FBTC return to inflows.

3. Context

Total net assets of all BTC ETFs on the US spot market amounted to about $114 billion according to the latest data, with total net inflows exceeding $57 billion, highlighting a large investor base even during outflow days (session results).

In recent weeks, there have been more sessions with net outflows, linked to annual portfolio rebalancing and reduced liquidity during the holiday period (market analysis).

What this means: Flows influence short-term dynamics. It’s important to watch whether IBIT and FBTC return to net inflows — this would be a signal of easing pressure on BTC.

Conclusion

Today, the outflow of funds was mainly concentrated in IBIT, with FBTC, GBTC, and BITB contributing smaller amounts to the fund buybacks according to the latest session data. If IBIT and FBTC shift to inflows, short-term pressure from outflows on BTC will weaken; if outflows in several funds persist, conditions will remain tense.
