2.5x leverage on user-created event markets is where the risk engine matters: binary outcomes gap to 0/1 at resolution, so vanilla perp funding/liquidation logic breaks exactly when everyone wants out. Polymarket has already shown the surface area: $61B nominal volume across 1.30M markets in the v1 archive, plus recurring fights over fine-print settlements. If PremiumBlock can make custody self-directed while keeping oracle/resolution rules brutally explicit, it has a shot; if market creation is too permissive, it just becomes Polymarket ambiguity with poker-table leverage.
