Researchers benefit from WebSocket streaming for live capture and REST APIs for batch analysis, enabling both real-time market observations and deep historical investigations into how information propagates through Polymarket.
Quantitative researchers use Sub-Second Arbitrage Signals from Resolved Markets to study the prediction-market research layer at tick resolution. With 11.4M+ snapshots, 11.4M+ snapshots across 7 prediction-market categories, and a 14-column ClickHouse schema, the dataset supports rigorous market microstructure work on regime detection, arbitrage backtests, sentiment indices, factor models that simply isn't possible with aggregated OHLC sources.
Data challenges Quantitative Researchers run into
Sub-Second Arbitrage Signals from Resolved Markets is built around the data gaps Quantitative Researchers hit when they try to work with raw Polymarket feeds.
Prediction market datasets typically lack orderbook depth information
Published prediction market datasets (Manifold, CPMM datasets) provide only aggregate trade volumes or final outcomes, omitting the rich orderbook structure that reveals price discovery mechanisms. Researchers cannot analyze bid/ask spreads, order accumulation patterns, or market depth changes—the very microstructure that reveals when informed traders enter markets. Resolved Markets captures complete depth arrays, enabling investigation of information asymmetry and market efficiency questions that remain unanswerable with standard datasets.
Millisecond-precision timestamps unavailable from alternative sources
Academic research on prediction markets requires precise timing to correlate information arrivals with price movements. Standard prediction market APIs provide second-level or day-level timestamps, obscuring the millisecond-scale price discovery process. Resolved Markets' millisecond-precision timestamps enable sophisticated event-study methodologies, allowing researchers to measure how quickly Polymarket incorporates external information (news, sports outcomes, economic reports) into prediction prices.
Cross-category market analysis requires manual data fusion
Prediction market dynamics vary dramatically across crypto, sports, economics, and weather—but assembling a unified dataset requires independently scraping each category or using fragmented APIs. Manual data fusion introduces inconsistencies in timestamp precision, orderbook representation, and market coverage. Resolved Markets provides standardized orderbook snapshots across all 100+ tracked markets, eliminating data integration work and enabling cross-category analysis of market efficiency and herding behavior.
Real-time and historical data require separate infrastructure
Traditional research workflows separate real-time observation (for validating hypotheses on live markets) from historical analysis (for deep investigations). This split requires maintaining two separate data pipelines. Resolved Markets unifies real-time WebSocket streams and historical batch queries into a single API, allowing researchers to seamlessly transition from exploratory analysis of live markets to rigorous backtesting against months of historical orderbook data.
Built for quantitative work on Sub-Second Arbitrage Signals
Orderbook-level prediction-market data that doesn't exist anywhere else.
Investigate price discovery mechanisms at millisecond resolution
Price discovery happens at the orderbook level—before trades execute, bids and asks reveal trader intentions. With full depth arrays and millisecond timestamps, you can track how orders accumulate before price moves, quantify bid/ask asymmetry changes, and measure how quickly informed orders push prices toward fair value. Analyze moments when sudden order cancellations precede price reversals, revealing strategic order placement and information cascades invisible in trade-level data.
Analyze orderbook microstructure across 100+ markets simultaneously
Prediction markets exhibit distinct microstructure across categories: crypto markets show high-frequency trading dynamics, sports markets experience demand surges near game time, economics markets react to scheduled data releases. Resolved Markets captures cross-category orderbook data with consistent timestamping, enabling comparative studies of information flow and market maturity. Quantify whether crypto prediction markets are more efficient than sports or economics markets by analyzing order speed, spread compression, and depth changes.
Test market efficiency hypotheses with unbiased historical data
Published datasets introduce sampling bias—researchers often access only final outcomes or aggregate statistics, not the continuous orderbook snapshots that define true price paths. Resolved Markets' 11.4M+ snapshots covering months of data eliminate survivor bias and provide the complete information set available to market participants at any moment. Historical queries directly reveal when arbitrage opportunities existed, whether informed traders exploited them, and how quickly prices converged to fundamental values.
Publish reproducible research with timestamped, auditable datasets
Reproducible research requires datasets that can be audited and independently verified. Resolved Markets provides timestamped, immutable orderbook snapshots stored in ClickHouse with query-transparent access—you can export exact data used in analyses, enabling other researchers to validate findings or extend work. REST API batch exports include snapshot checksums, ensuring data integrity across research teams and publications.
