CCXT now supports Prediction Markets! (v4.5.66+)

Trade Polymarket, Kalshi, Hyperliquid, Limitless and Myriad with the unified CCXT API — available in all CCXT languages: JavaScript/TypeScript, Python, PHP, C#, Go and Java. More prediction exchanges will be added shortly!

Instead of a market symbol you address an outcome (MARKET:LABEL, e.g. TRUMP_WIN_2024:YES) — or just pass the venue's raw outcome id, both work. Prices are probabilities (0–1), amounts are shares. Discovery starts with fetchEvents({}) — no loadMarkets() needed:

import ccxt.prediction
exchange = ccxt.prediction.polymarket()
events = await exchange.fetch_events({'query': 'bitcoin'})
outcome = events[0]['markets'][0]['outcomes'][0]['outcome']
order = await exchange.create_order(outcome, 'limit', 'buy', 5, 0.02)

All the unified methods work: fetchTicker, fetchOrderBook, createOrder, fetchPositions, watch* and more.
