Quad witching expiration is happening on Friday But what the hell is Quad Witching, and why does it matter for Bitcoin? Quadruple Witching is an event when 4 derivatives (stock index futures + options, single-stock futures + options) expire at once. It happens 4 times a year and creates significant stock volatility as funds roll positions. And that volatility often spills into BTC. Last 2 quad witchings this year → BTC went volatile, consolidated, then pumped. We saw the same thing in Sept 2021 (post-halving year). Now it’s Sept 2025 — another post-halving year — and the setup looks similar. If history rhymes, Bitcoin consolidates here before breaking out in October.(Lark Davis)
