Market nodes support two prediction venues:
  • polymarket (default)
  • kalshi

​
Venue selection

In node configuration, set the market venue first, then choose the market reference for that venue:
  • Polymarket: token ID-backed markets.
  • Kalshi: Kalshi ticker-backed markets (for example INXD-26DEC29-T4500).
The selected venue is persisted on the node, so downstream pricing and execution use the correct market source.

​
YES/NO side selection

Market nodes can track either side of the market:
  • YES side: direct yes price/bid/ask.
  • NO side: inverted probability from YES where needed, while preserving spread semantics for that side.
Use side selection when your strategy thesis is explicitly contra to the base market statement.

​
Update cadence differences

  • Polymarket: live updates are streamed from WebSocket market data.
  • Kalshi: market updates are REST-polled (no public unauthenticated WS stream in current integration path).
Because of that, Kalshi node charts and price changes can appear less granular than Polymarket live charts.
