Karoline Leavitt press-briefing mention markets
Kalshi Definitional vagueness · 2026-01 · notional unreported · status: resolved
What happened
At the officially scheduled briefing, Trump took the podium for ~2 hours; Leavitt never reached the lectern and said no strikes. Kalshi treated the event as 'the next press briefing' and resolved all strikes No; traders argued the briefing never occurred and should have rolled.
Resolution outcome
All strikes resolved No.
The drafting lesson
'The next X' needs a definition of X actually occurring.
Failure type — Definitional vagueness: A key term ('suit', 'ban', 'invasion', 'go live') is undefined or defined differently than traders assumed.
