What if Bitcoin spot ETFs face mass redemptions?
A $5bn multi-day spot-ETF outflow forces APs to sell underlying BTC into thin books, with MSTR (-7.5%) the highest-beta casualty as its NAV premium compresses. Rhymes with the early-2024 GBTC unwind and the Oct-2025 $19bn liquidation cascade, where reflexive ETF selling overshot fundamentals. Forward angle: ETF ownership is now the marginal price-setter, so flow reversals hit faster and deeper than in the pre-ETF era.

What it would mean
If this plays out, it is a mixed shock. A multi-day $5 billion outflow wave from US Bitcoin spot ETFs forces authorized participants to dump underlying BTC.
