According to @FarsideUK, US spot Bitcoin ETFs posted a total net inflow of $54.8 million on 2025-12-05 (source: @FarsideUK, farside.co.uk/btc, Dec 6, 2025). Inflow leaders were ARKB with $42.8M and FBTC with $27.3M, followed by HODL with $11.4M, BITB with $4.9M, and BTCW with $0.9M (source: @FarsideUK, farside.co.uk/btc, Dec 6, 2025). IBIT recorded a net outflow of $32.5M, while BTCO, EZBC, BRRR, GBTC, and BTC registered zero flow for the session (source: @FarsideUK, farside.co.uk/btc, Dec 6, 2025). For traders, the positive aggregate flow was driven by ARKB and FBTC inflows offsetting IBIT outflows, a useful read-through for tracking BTC demand via ETF subscriptions and redemptions (source: @FarsideUK, farside.co.uk/btc, Dec 6, 2025).
