Deep Dive

1. From Inflows To A Sharp Outflow

The most notable change was a single?day net outflow of about $194.6 million around Dec 4, breaking the preceding inflow run.

• The days redemptions were led by BlackRocks IBIT (~$113 million) and included Fidelitys FBTC (~$54.2 million), marking the largest daily outflow in two weeks per an AMBCrypto analysis and a corroborating Decrypt report.
• Bloomberg data also shows IBIT in a multi?week outflow streak totaling $2.7 billion through Nov 28, highlighting a persistent shift in flows per Bloomberg via Yahoo Finance.

2. A Brief Inflow Streak Before The Break

Earlier in the week, US spot BTC ETFs notched five consecutive inflow sessions, including $58 million on Tuesday.

• The inflow streak coincided with BTCs rebound and the average ETF holders cost basis turning favorable, per a CoinJournal update.
• A separate daily snapshot showed a smaller net outflow (~$14.9 million) that broke the streak mid?week, consistent with mixed flows reported by mainstream outlets per a Yahoo Finance market update.

3. Why The Shift Happened

Multiple sources attribute the flow reversal to the unwinding of basis trades and broader leverage reduction, not broad capitulation.

• Outflows were concentrated among a few issuers and linked to collapsing futures carry spreads, forcing arbitrage unwinds per an Amberdata research summary.
• Mixed macro signals and thin year?end liquidity amplified the impact of redemptions, reinforcing a cautious stance among institutional allocators per Investing.com commentary.

Conclusion

BTC ETF flows flipped from a modest multi?day inflow streak to a concentrated outflow day, driven largely by basis?trade unwinds and issuer?level dynamics. The near?term picture remains mixed: creations can resume as leverage resets, but thin year?end liquidity means outsized flow days can still sway price and sentiment.
