To browse and interact with Polymarket prediction markets from OpenClaw, run `clawhub install polymarket` — no API key required for reading. The skill lets you browse all active markets, search by topic or category, read current odds and volume, and explore prediction market data for elections, crypto events, sports, and more directly from OpenClaw chat.
Browse and Search Polymarket Prediction Markets from OpenClaw Chat
Prediction markets provide something uniquely valuable: an aggregated, financially-incentivized probability estimate for future events. Participants bet real money on outcomes, which aligns incentives toward honest beliefs rather than motivated reasoning. Polymarket has emerged as the dominant venue for this kind of market, running billions in trading volume on thousands of active markets covering everything from presidential elections to Bitcoin price milestones to scientific discoveries.
The OpenClaw Polymarket skill gives you a full interface to this information layer from your AI agent workflow. Unlike the companion Polymarket Odds skill which is optimized for quick probability lookups on specific events, the Polymarket skill provides the full browsing experience: search all active markets, explore by category, find trending markets with the most recent activity, read full resolution criteria to understand exactly what conditions make a market resolve YES or NO, and compare markets within a topic to build a comprehensive view of how the crowd is pricing related events.
This is particularly powerful as a research and decision-support tool. Before a major strategic decision that depends on uncertain external factors, you can ask OpenClaw to scan all relevant Polymarket markets, summarize the collective odds, and give you a data-driven prior to work from. Combined with live crypto prices, DEX data, and AI-powered web search, Polymarket adds the dimension of collective human judgment — real money on real outcomes — to your research process.
Integration method
The Polymarket skill connects to Polymarket's public API to browse, search, and read all active markets without authentication. You can explore markets by category, search for specific events, compare probabilities across related markets, and read full market details including current odds, trading volume, resolution criteria, and commentary. No API key or wallet connection is required for read operations.
Prerequisites
- OpenClaw installed and running (see openclaw.ai for installation instructions)
- ClawHub CLI available in your terminal (bundled with OpenClaw)
- Internet access for live market data (no account or API key required for reading markets)
Step-by-step guide
Install the Polymarket Skill via ClawHub
Install the Polymarket Skill via ClawHub
Open your terminal and run the ClawHub install command. The Polymarket skill has no required configuration for read operations — Polymarket's public API allows full market browsing and data reading without authentication. The install completes in seconds. Note that the broader Polymarket skill and the focused Polymarket Odds skill are different packages with different purposes. The Polymarket skill covers browsing, searching, and detailed market reading. The Polymarket Odds skill is optimized for quick probability lookups on known events. You can install both if you want both capabilities available in OpenClaw chat. If you also want to place bets or interact with markets as a participant, that requires wallet configuration which is covered in the advanced section.
1clawhub install polymarketPro tip: Run `clawhub install polymarket-odds` as well if you want the quick-lookup odds skill alongside this full browsing skill. They complement each other well for different types of queries.
Expected result: Terminal confirms: 'polymarket@X.X.X installed successfully. No required config for read access.' The skill is immediately active.
Browse Markets and Search for Events
Browse Markets and Search for Events
Open OpenClaw chat and explore Polymarket's market catalog. The skill can browse by category, search by keyword, find trending markets, and look up specific events you care about. Polymarket organizes markets into categories including: Crypto, Politics, Sports, Science & Technology, Business & Finance, Entertainment, and more. Each market has a title (the yes/no question), current probability, volume, and resolution date. For effective searches, use key nouns and concepts rather than full questions. 'Bitcoin ETF' finds more markets than 'Will the Bitcoin ETF see record inflows in 2026?'. The skill searches titles and descriptions, so both work — but broader terms cast a wider net. The most useful data points to request for each market are: current YES probability, total trading volume, days until resolution, and the resolution criteria (the specific rule that determines how the market settles).
Browse Polymarket for all markets related to 'artificial intelligence' that are currently active. Show me the top 10 by volume with their current probabilities, resolution dates, and a brief summary of what each market is asking.
Paste this in OpenClaw chat
Pro tip: Ask OpenClaw to explain the resolution criteria for any market you find interesting — understanding exactly what counts as YES and what counts as NO is essential for correctly interpreting the probability.
Expected result: OpenClaw returns a list of AI-related Polymarket markets with probabilities, volumes, and resolution dates, sourced live from Polymarket's API.
Read Full Market Details and Resolution Criteria
Read Full Market Details and Resolution Criteria
When a market looks relevant to a research question or decision, ask OpenClaw to pull the full market details. Beyond the probability and volume, the resolution criteria is the most critical piece of information — it tells you exactly what the market is actually betting on. For example, a market titled 'Will BTC hit $100k by end of 2026?' might resolve YES only if BTC's daily close on a specific exchange exceeds $100k on December 31st. The resolution source (which data provider determines the outcome), the resolution timing, and edge cases all matter for correctly interpreting what the probability represents. Additionally, many Polymarket markets have comments from participants explaining their reasoning. These comments can be high-signal, as they often come from participants who have done significant research and are financially committed to their view. Ask OpenClaw to include top comments when fetching market details. RapidDev can help build research workflows in OpenClaw that systematically incorporate Polymarket data alongside trading data from Hyperliquid and crypto prices into a unified decision-support pipeline.

Research Synthesis: Building a Multi-Market View
Research Synthesis: Building a Multi-Market View
The most sophisticated use of the Polymarket skill is building a comprehensive view of how markets are pricing a complex situation. This means finding all relevant markets for a topic, understanding how they relate to each other, and synthesizing the combined signal into an actionable research insight. For example, if you're assessing political risk for a business decision, you might pull all active US political markets, group them by topic (election outcomes, regulatory decisions, legislative outcomes), compare probabilities within each group, and identify where the market is most confident vs most uncertain. For investment or trading decisions, compare event markets with price target markets — the probability of a specific price target hitting can be compared against the on-chain market data from Hyperliquid's funding rates and open interest to see if the derivatives market and the prediction market are telling consistent or inconsistent stories. This multi-signal analysis approach — combining Polymarket's crowd wisdom with live market data and news context — is what makes OpenClaw a genuinely powerful research environment.
Comprehensive analysis: find all Polymarket markets related to the US elections in 2026. Group them by type (Senate races, gubernatorial races, ballot measures, policy outcomes). For each group, show the markets, probabilities, and volumes. Then summarize what the collective markets imply about the overall political landscape for 2026.
Paste this in OpenClaw chat
Pro tip: When researching complex topics, ask OpenClaw to synthesize the market probabilities into an 'implied scenario' at the end of the query — this translates a table of numbers into a coherent narrative about what the market collectively believes is most likely to happen.
Expected result: OpenClaw returns a structured, grouped analysis of related Polymarket markets with a synthesized narrative at the end describing what the collective probabilities imply about the overall situation.

Troubleshooting
OpenClaw returns empty results when searching for a market that exists on polymarket.com
Cause: The search terms may not match the market title closely enough. Polymarket market titles use specific phrasing, and the API search may require closer matching than a general web search.
Solution: Try searching with fewer, more specific keywords (e.g., 'Fed rate cut Q2' instead of the full question). Also check if the market has already resolved — resolved markets may be excluded from search results by default. If needed, browse by category instead of searching.
clawhub install polymarket fails with a network error or registry timeout
Cause: Temporary ClawHub registry issue.
Solution: Wait 2-3 minutes and retry. Use --force to clear partial installation state.
1clawhub install polymarket --forcePolymarket probabilities don't match what I see on polymarket.com
Cause: The API may have a brief caching delay, or the skill may be formatting probabilities differently (e.g., rounding). Polymarket's displayed prices can also slightly differ from raw API values due to order book mechanics.
Solution: Small differences (0.5-2%) between API and website display are normal due to bid-ask spread representation. Larger discrepancies may indicate the skill is querying a cached snapshot — wait a few minutes and query again.
The skill returns too many results and it's hard to find the relevant market
Cause: Broad category queries return many markets. Without a minimum volume filter, low-quality thin markets may appear alongside important ones.
Solution: Configure min_volume in your skill config to filter low-quality markets. Also use more specific search terms to narrow results. Ask OpenClaw to 'sort by volume descending' to see the most-traded (and thus most reliable) markets first.
1# In ~/.openclaw/skills/polymarket.yaml2polymarket:3 min_volume: 100004 default_sort: volumeBest practices
- No API key required — install and start browsing markets immediately without any configuration.
- Always read resolution criteria before relying on a probability — what a market is technically asking can differ significantly from its colloquial title.
- Weight market probabilities by volume — a market with $1M in volume provides a more reliable signal than one with $1K in volume.
- Set a minimum volume filter in your skill config to automatically exclude thinly-traded markets from browse results.
- Use prediction market probabilities as calibrated priors, not certainties — they represent the market's best estimate given current information, and new information can move them sharply.
- Combine Polymarket data with Hyperliquid funding rates and Crypto Price data for multi-signal analysis of crypto events — the three data sources provide complementary views of market sentiment.
- Install both polymarket (browsing) and polymarket-odds (quick lookup) for full coverage — use whichever is appropriate for the task at hand.
Alternatives
Polymarket Odds is the focused quick-lookup version — use it when you know which event you want and just need the probability fast, rather than browsing.
Crypto Price provides live spot market prices — use it alongside Polymarket to compare actual market prices with prediction market probability estimates for price events.
Hyperliquid provides DEX trading data including funding rates and open interest — use it with Polymarket to compare derivatives market positioning with prediction market probabilities.
Technical Analyst provides chart-based trading signals — pair its technical analysis with Polymarket's event probabilities for a more complete analytical framework.
Frequently asked questions
How do I install Polymarket in OpenClaw?
Run `clawhub install polymarket` in your terminal. No API key is required — the skill connects to Polymarket's public API immediately and you can browse markets from OpenClaw chat. For quick probability lookups on specific events, also install `clawhub install polymarket-odds` as a companion skill.
What is the difference between the Polymarket skill and the Polymarket Odds skill in OpenClaw?
The Polymarket skill provides full market browsing, category search, trending market discovery, and detailed market information including resolution criteria. The Polymarket Odds skill is optimized for a single use case: quickly looking up the probability for a specific known event. Install both if you need both capabilities — they complement each other and have no conflict.
How accurate are Polymarket prediction markets?
Polymarket markets are generally well-calibrated, especially for high-volume markets — events assigned 70% probability by the market resolve YES roughly 70% of the time historically. The key factors affecting accuracy are market volume (higher is better), time to resolution (near-term events are more accurately priced than long-term ones), and whether the market has clear, objective resolution criteria.
Does RapidDev help with Polymarket research workflows in OpenClaw?
Yes — RapidDev can help build research pipelines in OpenClaw that combine Polymarket market data with Hyperliquid trading data, crypto prices, and AI-powered news search for comprehensive event-driven analysis. Simple market browsing as described on this page is self-serve, but systematic research workflows across multiple skills benefit from structured configuration support.
Can I place bets on Polymarket through OpenClaw?
The basic skill installation covers read-only market browsing and probability reading. Placing bets requires wallet-level authentication with a Polygon wallet that holds USDC. This capability is in the skill's advanced configuration — the OpenClaw documentation covers wallet integration for users who want to interact with Polymarket markets as participants.
Why is the Polymarket skill not finding active markets in a specific category?
Try adjusting your search terms to match how Polymarket titles its markets, and ensure your min_volume filter isn't too high for the category you're searching. Some categories (like sports) have markets concentrated around specific seasons. Also confirm your include_resolved setting isn't excluding active markets accidentally. Browse with category: 'all' and include_resolved: false as a starting point.
