20Hz Capture Rate for Sports Analysts
Resolved Markets provides sports analysts with real-time orderbook data from NBA, NFL, and EPL prediction markets on Polymarket, capturing market sentiment through bid/ask spreads and order flow dynamics before games occur. Access continuous orderbook snapshots with millisecond timestamps and full depth arrays, enabling you to identify when sharp bettors accumulate positions, detect line movement ahead of public perception, and forecast outcomes by analyzing collective prediction market pricing. The platform tracks 100+ sports-related markets with 20Hz capture rates during high-volume periods, WebSocket streaming for live updates, and historical data for detailed post-game analysis of market accuracy and predictive power.
Sports analysts working on Polymarket sports contracts need more than closing lines. 20Hz Capture Rate from Resolved Markets provides 20Hz continuous snapshots delivered via REST, WebSocket, CLI, and MCP across WebSocket streams, REST snapshots, CLI bulk exports, MCP servers, so analysts can quantify pre-game depth, in-play sentiment, and live spread compression.
Data challenges Sports Analysts run into
20Hz Capture Rate from Resolved Markets is built around the data gaps Sports Analysts hit when they try to work with raw Polymarket feeds.
Traditional betting lines hide order flow and market depth
Sportsbooks publish final betting lines (point spreads, totals, moneylines) but don't reveal orderbook depth, spread width, or order accumulation patterns. Prediction markets on Polymarket show richer information—you can see exactly where liquidity clusters, how wide bid/ask spreads widen during uncertainty, and when large orders cause prices to shift. Traditional line data obscures this microstructure, leaving you unable to distinguish between genuine market consensus and thin, uninformed pricing.
Prediction market prices often move before public becomes aware
Sharp sports bettors and professional traders often move prediction market prices hours or days before casual bettors notice. By the time a line appears in mainstream betting forums, informed traders have already positioned. Resolved Markets captures continuous orderbook snapshots, revealing when unexpected buying (or selling) pressure emerges—the signal that sharpness is accumulating. Real-time WebSocket streams and millisecond timestamps let you detect position building moments before prices move 5-10 points.
Sharp money accumulation patterns remain invisible
Public betting lines show only final price, not the journey to reach that price. Did that NFL spread move 2 points because of sharp money or casual volume? Orderbook depth analysis reveals the answer—sharp orders typically result in steep spread compression and rapid order accumulation at specific price levels. Resolved Markets' full depth arrays show you the structure of orders behind each price level, distinguishing intelligent hedging from noise.
Post-game market analysis tools are limited or non-existent
After games conclude, sportsbooks don't publish how accurate their pre-game lines were or analyze why prediction markets mispriced certain outcomes. Resolved Markets' historical orderbook data enables detailed post-game reviews—compare final game results against the distribution of bid/ask prices throughout pre-game trading, identify which price ranges accumulated the most liquid orders (the market consensus), and measure how information (injury reports, weather changes) affected orderbook microstructure during the game.
Built for quantitative work on 20Hz Capture Rate
Orderbook-level prediction-market data that doesn't exist anywhere else.
Detect sharp money movement before consensus shifts
Sharp professional bettors move prediction market orderbooks in distinctive ways—they accumulate large positions gradually (creating steep order accumulation at specific price levels) or strike suddenly when they find mispricing. Resolved Markets' continuous orderbook snapshots reveal these patterns through order clustering analysis and spread compression tracking. When you see sudden deepening of the buy side at a specific price, followed by gradual uptick in buy volume, that's often sharp accumulation—a signal to pay attention before the rest of the market reprices.
Quantify market confidence through bid/ask spread compression
Bid/ask spreads in prediction markets widen dramatically when market participants disagree about fair value. Resolved Markets captures spread width changes at millisecond intervals, revealing moments of high uncertainty and opportunity. Narrow spreads indicate consensus; suddenly widening spreads signal disagreement—often because new information is emerging. Track spread compression over hours before games as consensus hardens, identifying when markets have shifted from uncertain to confident about outcomes.
Track order accumulation patterns for directional signals
Unlike traditional betting lines where all liquidity pools at discrete points (7-point spread, 3-point spread), Polymarket orderbooks show continuous price levels with varying depth. Analyze where orders cluster to identify the market consensus—NBA game orderbooks might show dense selling at over 105.5 points and dense buying at under 104.5 points, indicating strong consensus around 105 points. Resolved Markets shows these order accumulation zones, revealing where market participants genuinely believe prices should settle.
Measure prediction market accuracy for sports outcome forecasting
Historical orderbook analysis enables post-game confidence calibration. Did markets price an outcome at 65% likelihood (odds of 1.85), but that outcome occurred in 70% of similar situations? Did early game orderbooks show lopsided depth on one side that disappeared as game progressed? Resolved Markets' historical snapshots let you analyze pre-game confidence distribution and measure whether prediction markets accurately reflected true event probabilities—critical for improving your forecasting.

Frequently asked: 20Hz Capture Rate for Sports Analysts
-
How does Polymarket's orderbook data for NFL/NBA games compare to traditional sportsbook lines?
Sportsbooks publish a single price (7-point spread, for example) representing their midpoint—you don't see bid/ask or order depth. Resolved Markets shows you the full orderbook, revealing bid/ask spreads (maybe 6.8 to 7.2), order volume at each price level, and how prices move as new orders arrive. This microstructure is invisible in traditional lines and often moves 1-2 hours before sportsbooks adjust their published spreads.
-
Can I use orderbook data to predict game outcomes better than published lines?
Prediction market prices already reflect sophisticated betting, so they're statistically difficult to beat. However, orderbook microstructure often reveals mispricings or sharp money signals before prices fully adjust. Track when order depth suddenly increases on one side (suggesting informed money), or when bid/ask spreads compress (indicating emerging consensus). Combine orderbook analysis with your own game analysis to identify moments when markets are temporarily inefficient.
-
Do you capture orderbooks for all sports markets, or only major leagues?
Resolved Markets captures 100+ sports markets including NBA, NFL, and EPL at high frequency during active trading periods (pre-game, halftime for ongoing games). We also track lower-profile sports and specific bet types (player props, quarter/half bets) when Polymarket offers them. WebSocket streams prioritize high-volume periods; query historical data for any tracked sport.
-
What's the latency between an event (like an injury report) and the reflected change in prediction market orderbooks?
With millisecond-precision timestamps, Resolved Markets captures the exact timing of orderbook responses to external events. Injury reports typically trigger reordering within 10-60 seconds on Polymarket, visible as sudden spread widening and order volume shifts. Historical data lets you measure typical response latencies for different event types, revealing whether prediction markets are fast or slow to incorporate sports information.
-
Can I export historical orderbooks for all games in a season for research?
Yes—the REST API supports batch queries for date ranges, teams, or sports categories. Export complete orderbook snapshots for an entire NFL season with bid/ask depth, timestamps, and order volumes. ClickHouse backend processes season-long queries quickly, and exported data includes metadata enabling game-level analysis (teams, game time, final score) for correlation studies.
-
How do sports analysts use 20Hz Capture Rate?
Sports analysts watch bid-ask spreads inside 20Hz Capture Rate to identify sharp versus public betting, depth shifts before major events, and market overreactions. 20Hz continuous snapshots delivered via REST, WebSocket, CLI, and MCP reveals intraday momentum that closing lines hide.
-
Which sports markets are covered by 20Hz Capture Rate?
20Hz Capture Rate spans WebSocket streams, REST snapshots, CLI bulk exports, MCP servers — NBA outcomes, NFL games, EPL matches, March Madness, Tennis, World Cup, and Olympic results. All Polymarket sports contracts are continuously sampled.
-
Can 20Hz Capture Rate detect sharp money before lines move publicly?
Yes. Sharp money typically causes rapid spread compression and depth shifts at specific prices. 20Hz continuous snapshots delivered via REST, WebSocket, CLI, and MCP surfaces these microstructure events inside 20Hz Capture Rate, often hours before mainstream odds move.
-
Can I run 20Hz Capture Rate in a serverless environment?
Yes. The REST API works from any HTTP client, including Cloudflare Workers, AWS Lambda, Vercel functions, and Modal containers. WebSocket streams work in long-running environments like Fly.io or Railway.
-
Does 20Hz Capture Rate have an MCP server?
Yes — `npm install -g resolved-markets-mcp` installs an MCP server that exposes 20Hz Capture Rate as function calls. Drop it into your Claude Desktop or Cursor MCP config and your agents can query live prediction-market data on demand.
