Question 1

What prediction market data does Telonex provide?

Accepted Answer

Telonex is the most comprehensive source for historical prediction market data. Its flagship dataset covers Polymarket, the world's largest prediction market: every executed trade, order book snapshots at multiple depth levels, best bid/ask quotes, onchain settlement data with wallet addresses, and the crypto price feeds (BTC, ETH, SOL, XRP, BNB, DOGE, HYPE) Polymarket uses to resolve crypto markets. Telonex also covers Polymarket Perpetuals (including funding rates and open interest), Predict.fun, and Binance spot data. Across all sources: 1M+ markets and 100 billion+ data points spanning 3+ years of history.

Question 2

Which exchanges does Telonex support?

Accepted Answer

Four exchanges today: Polymarket (trades, quotes, order books, onchain fills, and crypto resolution prices), Polymarket Perpetuals (trades, quotes, order books, and a derivative ticker with funding rates and open interest), Predict.fun (order books, quotes, and onchain fills from BNB Smart Chain), and Binance spot (BTC, ETH, SOL, XRP). More exchanges are on the way - if there is a venue you need covered, tell us at support@telonex.io. Every exchange shares the same normalized schema and download API.

Question 3

Do you have Polymarket perpetuals historical data?

Accepted Answer

Yes.

Question 5

Can I backtest prediction market strategies with this data?

Accepted Answer

Yes. Telonex provides the tick-level trades and order book snapshots needed for realistic strategy backtesting — including slippage modeling and fill probability estimation. Unlike OHLCV candles, our data captures every market event for accurate simulation.
