4-bullet brief | narrative

The Kalshi contract puts only 20% odds on the Supreme Court hearing a tariff case in 2026, resolving via Supreme Court records.
Despite critics framing the new tariffs as circumventing Congress, prediction markets give only a 1-in-5 chance of a Supreme Court case reaching argument stage this year.
The low odds likely reflect the Supreme Court's docket timeline, not a view on tariff legality, as expedited review is rare absent emergency injunctions.
Companion ladder CM-EVT-8P2Y9LGSL3 prices the effective tariff rate at 7.5-10%, suggesting markets expect tariffs to take economic effect well before any legal resolution.
