According to @Andre_Dragosch, the latest Bitcoin (BTC) upside was primarily derivatives-led rather than spot-driven, citing a +$900M options open interest delta (price-adjusted) and only +$467M spot volume delta (source: @Andre_Dragosch on X, Jan 15, 2026). He reports US spot Bitcoin ETF net inflows of +$47M, versus a futures open interest delta of +$182M (price-adjusted), indicating stronger participation from leveraged markets (source: @Andre_Dragosch on X, Jan 15, 2026). Perpetual funding rates were negative and short futures liquidations spiked, while the put-call ratio was essentially unchanged, suggesting balanced call and put OI increases (source: @Andre_Dragosch on X, Jan 15, 2026). He adds that a short gamma squeeze could have driven incremental spot demand during the move (source: @Andre_Dragosch on X, Jan 15, 2026).
