Data scientists leverage Resolved Markets to build predictive models using 11.4M+ orderbook snapshots from Polymarket across crypto, sports, economics, and weather categories. The platform provides raw bid/ask depth arrays with millisecond timestamps—ideal for feature engineering, time-series analysis, and market microstructure modeling. With continuous 20Hz capture rates for crypto markets and comprehensive coverage of 100+ prediction markets, data scientists can train models on real market behavior patterns, sentiment evolution, and price discovery mechanisms. The unified API and historical data storage enable reproducible research, backtesting frameworks, and deployment of models via WebSocket streaming for live predictions.

Multi-Domain Probability Data is the dataset data scientists actually want from prediction markets. 11.4M+ snapshots across 7 prediction-market categories produces clean, structured rows that map directly to pandas DataFrames, with rich orderbook microstructure features extractable from regime detection, arbitrage backtests, sentiment indices, factor models.

Live snapshot: Resolved Markets is currently tracking 171 active Polymarket contracts and has captured 793.2M orderbook snapshots. Latest update: 2026-05-09 03:14:12.061.

Data challenges Data Scientists run into

Multi-Domain Probability Data from Resolved Markets is built around the data gaps Data Scientists hit when they try to work with raw Polymarket feeds.

01

Fragmented data sources requiring extensive ETL and normalization

Building prediction models requires consolidating data from sports betting APIs, crypto exchanges, economics calendars, and weather databases. Each source has different schemas, timestamps, data quality standards, and update frequencies. Data scientists waste weeks building ETL pipelines just to get consistent data for model training. Resolved Markets eliminates this integration burden by providing all four categories through a single, normalized API with consistent timestamp precision and schema.

02

Insufficient orderbook depth granularity for sophisticated microstructure models

Most market data providers deliver only OHLCV candles—open, high, low, close, volume. This completely discards orderbook microstructure where the signal lives. Sophisticated traders and algorithms exploit bid/ask spreads, depth clustering, and order book imbalances minutes before price moves. Resolved Markets provides full depth arrays showing every bid and ask level, enabling feature engineering on fundamental market structure rather than derived price metrics.

03

Limited historical data windows for training robust prediction models

Historical prediction market data is nearly impossible to acquire at scale. Most platforms don't archive snapshots, leaving data scientists with limited training windows of days or weeks. Resolved Markets maintains 11.4M+ snapshots across 100+ markets with millisecond precision. This depth enables training time-series models on diverse market regimes, economic cycles, election outcomes, and sports season progressions—impossible with limited data.

04

High operational overhead managing real-time data pipelines

Real-time data pipelines are operationally complex: maintaining WebSocket connections, handling reconnection logic, buffering, deduplication, and writing to analytical databases. Building this infrastructure takes months and requires dedicated engineering. Resolved Markets abstracts this complexity through simple API endpoints and WebSocket subscriptions, letting data scientists focus on modeling rather than infrastructure.

Built for quantitative work on Multi-Domain Probability Data

Orderbook-level prediction-market data that doesn't exist anywhere else.

01

Millisecond-precision timestamps enable accurate microstructure feature engineering

Every orderbook update is timestamped to the millisecond, enabling precise sequence analysis and event-driven modeling. You can engineer features like 'time_to_next_large_buy_order', 'depth_concentration_ratio', and 'spread_evolution_velocity'—metrics that predict price moves seconds or minutes ahead. These ultra-precise timestamps turn raw orderbook data into predictive signals for microsecond-scale market efficiency models.

02

11.4M+ snapshots provide deep historical windows for robust model training

The 11.4M+ snapshot archive spans months of continuous Polymarket evolution. Your models can train on diverse market conditions: pre-election volatility (prediction markets repricing as new polls emerge), FOMC uncertainty (hourly probability shifts as economic data releases), sports event outcomes (live match developments changing contract prices), and crypto volatility (correlation with macro sentiment). This breadth prevents overfitting to narrow market regimes.

03

Full bid/ask depth enables advanced market structure analysis impossible with price data alone

Orderbook depth reveals market participant composition and conviction. When large bids appear at favorable odds, orders are building conviction. When depth clusters at certain levels, smart money is defending support/resistance. When spreads widen dramatically, information asymmetry is high. Resolved Markets' full depth arrays let you engineer these structural features directly, rather than inferring them from price changes that may have already occurred.

04

Unified API across 4 market categories enables cross-domain transfer learning

Training a single-category model (just crypto, or just sports) limits generalization. Resolved Markets' unified API across crypto, sports, economics, and weather enables transfer learning: patterns in how BTC price predictions reprices ahead of US macro data might apply to EPL match predictions. Cross-category feature spaces create richer representations, improving model robustness when deploying to new markets.

Frequently asked: Multi-Domain Probability Data for Data Scientists

  • What features can we engineer from Resolved Markets orderbook data?

    The full bid/ask depth enables dozens of microstructure features: bid-ask spread evolution, depth concentration ratios, order book imbalance (total_bid_quantity vs total_ask_quantity), volume-weighted midpoint shifts, time-to-best-execution, depth clustering entropy, and inter-arrival times between large orders. With millisecond timestamps, you can calculate volatility measures at sub-second timescales. These features capture market sentiment and conviction far better than price-only inputs.

  • Can we use historical snapshots for backtesting prediction models?

    Yes, our full historical archive of 11.4M+ snapshots enables authentic backtesting. You can train models on snapshots from period A, validate on period B, and backtest on period C with zero look-ahead bias. Each snapshot includes the exact timestamp and full orderbook state, enabling realistic simulation of your model's performance. Export snapshots in JSON or Parquet format for efficient processing in your training pipeline.

  • How do we handle missing data or gaps in the snapshot stream?

    Our capture process is continuous at 20Hz for crypto and variable intervals for other categories. Gaps occur only during platform maintenance (announced in advance). We provide metadata with each snapshot indicating the time since the last capture, enabling you to detect and interpolate over gaps. For production models, our WebSocket API guarantees delivery of every update; client-side buffering prevents data loss due to network transients.

  • Can we build models predicting Polymarket price movements before crypto spot markets move?

    Yes, this is a primary use case. Polymarket prediction contracts for BTC and ETH price direction often reprices minutes before spot price changes, as sophisticated traders discover new information. Train models on orderbook features from prediction markets to predict subsequent spot price direction. The unified API makes it simple to correlate prediction market orderbook evolution with spot price candles from any exchange, enabling cross-market alpha research.

  • What's the best way to handle the scale of 11.4M+ snapshots in training pipelines?

    Export snapshots to Parquet format for efficient storage and query. Our API supports time-range and market-range filtering to limit export scope. Use distributed computing frameworks (Spark, Dask, Ray) to parallelize feature engineering across snapshot partitions. For live training, subscribe to WebSocket streams for specific markets rather than querying entire historical datasets. This hybrid approach—historical exports for model development, streaming for live updates—optimizes both training speed and inference latency.

  • Can data scientists access live Multi-Domain Probability Data for inference?

    Yes. WebSocket streaming pushes sub-second updates for real-time inference. The MCP server exposes Multi-Domain Probability Data as function calls for AI agents.

  • How do data scientists prepare Multi-Domain Probability Data for ML?

    Multi-Domain Probability Data ships as a 14-column ClickHouse-optimized schema with bid prices, ask prices, depth at each level, market identifiers, and millisecond timestamps. It maps directly into pandas for feature engineering.

  • What ML projects use Multi-Domain Probability Data?

    Price prediction, sentiment classification, liquidity forecasting, anomaly detection, cross-market correlation, and outcome probability estimation. Multi-Domain Probability Data is rich enough for sequence models and statistical pipelines alike.

  • Can Multi-Domain Probability Data be used in a portfolio context?

    Yes. Many funds treat prediction markets as an alternative sleeve and use Multi-Domain Probability Data as the structured data feed. Risk-parity, factor-tilting, and sentiment-overlay strategies all consume Multi-Domain Probability Data.

  • Is there published research using Multi-Domain Probability Data?

    Yes — academic and industry researchers have published work on prediction-market microstructure using Resolved Markets data. The dataset is documented and reproducible, which makes it suitable for peer review.
