Same bet.
Different rulebook.
Kalshi and Polymarket often list the same event. Lockstep reads both rulebooks and flags the cases where they would pay differently.
Independent. Not affiliated with Kalshi or Polymarket. Not investment advice.One event.
Three endings.
Pick what happens on release day. The rows that decide the payout light up, and the verdict for that case changes.
Two venues can list the same event and still disagree on the details. A late release. A tie. A rounding rule. Those details decide who gets paid, and they sit deep in rulebooks nobody has time to read.
Two rulebooks. One verdict.
We line up every clause that decides a payout, then mark the one that breaks the match.
The clause that broke the match · illustrative
Both contracts pay the same in every case we checked.
At least one realistic case pays differently on each venue.
A rule is silent, or the outcome is left to the venue's discretion.
