4-bullet brief | narrative

Polymarket prices SCOTUS striking down the birthright citizenship executive order at 94%, with trading volume up 3,642% day over day.
The Supreme Court ruling is imminent; the surge in volume signals fresh capital entering the contract as the decision approaches.
The companion Kalshi contract (CM-EVT-JZ03HX93V0) prices the executive order actually coming into effect at only 6%, directly consistent with the 94% strike-down read.
Resolves via whitehouse.gov; a ruling that blocks the order from taking effect would settle the Polymarket contract YES.
