Naxos provides synchronized Level 2 order book and tick data across seven prediction market venues, normalizing microstructure differences for algorithmic
Overview
Naxos is a prediction market data and analytics platform that captures and normalizes Level 2 order books across seven venues: Polymarket, Kalshi, ForecastEx, Limitless, PredictIt, Drift BET, and Smarkets. It addresses three core challenges in prediction market trading: forward-only data with no backfill APIs, incompatible market microstructure across venues, and settlement non-fungibility that creates basis risk.
The platform delivers four institutional capabilities: un-backfillable historical L2 archives with millisecond reconstruction, canonical symbology and fungibility scoring, an asymmetric net-of-fee engine, and a local SDK with backtesting lab. Naxos normalizes Kalshi's reciprocal binary bids into standard USD bid-ask ladders in under 400 microseconds, scores every cross-venue contract pair 0–100 on settlement equivalence, and provides pre-calculated liquidity metrics and VWAP curves.
Subscribers access historical tick archives, real-time WebSocket feeds, REST endpoints, and Python/TypeScript SDKs. The platform is engineered for systematic desks, algorithmic traders, market makers, and quantitative researchers who need to execute cross-venue arbitrage, model latency and slippage, extract implied probability term structures, or analyze tick-level market microstructure.

Q&A
- How does NaxosData provide high-performance historical prediction market data?
- The NaxosData Tick Engine captures and reconstructs full Level 2 order books across Polymarket, Kalshi, ForecastEx, Limitless, PredictIt, Drift BET, and Smarkets. Subscribers access millisecond historical replays, REST endpoints, and scoped CSV, JSON, and Parquet exports directly via the high-throughput API and open-source Python SDK.
- What is the difference between raw tick streams and Millisecond L2 Reconstruction?
- Raw tick streams capture every individual WebSocket delta with microsecond timestamps, while Millisecond L2 Reconstruction deterministically synthesizes the complete Level 2 bid-ask order book at any precise millisecond in history, enabling backtesters to inspect market depth without replaying hours of delta logs.
- How does Kalshi reciprocal normalization work for algorithmic orders?
- Kalshi's native API only streams reciprocal Yes-No bids where buying NO at 36¢ is equivalent to selling YES at 64¢. NaxosData normalizes this reciprocal book in real time into canonical USD bid and ask ladders so execution algorithms interact with standard equities-style Level 2 books.
- Can I upgrade or downgrade my tier at any time?
- Yes. Tier changes take effect immediately with zero downtime. You can switch between Hobbyist ($0/mo), Quant Pro ($30/mo), and Institutional ($100/mo) directly from the dashboard terminal settings or via the API.
