Telonex is a historical data platform for prediction markets aimed at traders, researchers, and academics. Its core purpose is to download tick-by-tick historical data from prediction markets such as Polymarket for backtesting, research, and cross-market analysis.
[Main Data Coverage] The platform's primary dataset is Polymarket, which it calls "the deepest Polymarket dataset available," covering every trade, every order book change, quotes, and onchain fills. Onchain records date back to November 2022, and it officially claims to have 100B+ data points and 1M+ markets. In addition to Polymarket, it also covers Polymarket Perps (perpetual contracts for crypto and real-world assets, including trades, quotes, order books, funding rates, and open interest), Predict.fun (a prediction market on BNB Smart Chain, including order books, quotes, and onchain fills, traced back to its launch), and Binance spot (trades, quotes, and order books for BTC, ETH, SOL, and XRP, used for cross-market research with prediction markets). It states that more exchanges will be added later.
[Data Types and Features] According to its official description, the data provided includes:
- Tick-by-tick trades: captured tick by tick via websocket, with precise timestamps, prices, and volumes.
- Full order book updates: every change is captured tick by tick rather than sampled at intervals, making it possible to reconstruct the historical market state at any point in time.
- Best bid and ask quotes: updated whenever the best quote changes, for spread analysis and market-making research.
- Daily order book snapshots: use the end-of-day market state as a starting point, avoiding the need to replay millions of events from the beginning.
- Cryptocurrency settlement prices: the exact price tick Polymarket uses to settle its crypto markets (BTC, ETH, SOL, etc.), including source and receipt timestamps.
- Onchain wallet data: wallet-level activity indexed from Polygon and BNB Smart Chain logs, used to track large traders and analyze fund flows.
- Market metadata: market titles, outcomes, settlement status, and identifiers, downloadable for free without an account.
[Data Methodology] It emphasizes that its construction approach focuses on reproducibility and research reliability, including: a unified normalized event architecture for all markets; automatic validation, deduplication, and completeness; partitioning by date for batch analysis; complete onchain history; tick-by-tick capture rather than interval sampling; redundant collection via independent websockets on multiple servers to preventNetwork outages cause data gaps; infrastructure upgrades with zero-downtime updates.
[How to use] The official instructions for downloading historical data are in three steps: 1) Log in with a Google account and create a free account, no credit card required; 2) Instantly generate an API key; 3) Download historical data via the Python SDK or REST API, with files in daily Parquet format that can be loaded directly into pandas, DuckDB, or Polars. The official statement says it takes less than two minutes from registration to first download, and it uses a unified schema and a single API key.
[Use cases] The official list includes the following use cases: quantitative traders and algorithmic traders conducting strategy backtesting; independent researchers and academics analyzing market microstructure, spreads, market making, capital flows, and large trader behavior. Official research article examples include: how sponsored liquidity rewards changed Polymarket's Jesus market (a tick-by-tick case study); an analysis of top crypto trader strategies on Polymarket within one week (an analysis of 46,945 wallets and $153 million in trading volume).
