Prediction Markets

Integrate non-sports Prediction Markets through your existing TRADE connection

Prediction Markets are available through TRADE using your existing RabbitMQ connection. No separate feed, queue, or endpoint is required.

Content is sourced from Kalshi and covers a range of non-sports categories. Prediction Market fixtures follow the Outright League message structure — the prediction category acts as the competition container, and each prediction question is represented as a fixture.

Odds

Prediction Market odds are normalized from provider stake values:

Odds = 1 / Stake (cents)

Odds are delivered already normalized — no additional conversion is required.

---

Settlement

Settlement is confirmed manually by LSports after provider confirmation. Do not assume settlement is sent immediately after a market closes. Drive settlement logic from the Outright League Settlement message.

---

Rendering

Market ID 3455 — Render a single Yes / No pair against the fixture question.

Market ID 3456 — Render one Yes / No pair per selection line. Use Line as the display label and ParticipantId as the logical identifier where provided.

Integration Notes

No new connection required — Prediction Markets are delivered through the existing TRADE RabbitMQ infrastructure. No new queue, vhost, or endpoint is needed.

Livescore does not apply — Prediction Markets have no live score phase. Do not expect in-play score progression or scoreboard-driven state changes.

Reconnection — After reconnecting, request a snapshot before resuming normal consumption.
