A multi-outcome event, such as “Who will win?” with several candidates, is a group of binary markets where exactly one market resolves Yes. CHOK links these markets through the Neg Risk Adapter contract.

​
Why it matters

In a group where only one answer can win, holding No on one candidate is economically linked to holding Yes on all the others. The adapter lets you convert No shares:
Convert 1 No share on each of k candidates into 1 Yes share on every other candidate, plus (k − 1) chUSD.
Example with candidates A, B and C:
  • You hold 1 No on A and 1 No on B (k = 2).
  • Converting gives you 1 Yes on C and 1 chUSD.

​
On CHOK

  • Multi-outcome events appear as one event with a row per candidate. Each row is a regular Yes/No market.
  • In a market’s positions table, use Convert to turn No shares into Yes shares on the other candidates.
  • Each candidate’s market resolves separately. When one resolves Yes, the others resolve No. See Resolution.
