Declared capabilities

  • Search open prediction markets on any topic
  • Show market-implied odds for every outcome of a market
  • Rank the candidates or outcomes of multi-outcome events

Cost & access

PolyScan does not sell products, process payments or place trades. It only reads public prediction-market data.

Declared limitations

  • Trade execution request. It must not be completed because PolyScan is read-only: it has no tools to place, simulate or route an order, and order execution is outside the plugin's purpose.
  • Personalized financial advice. It must not be completed: the user asks which market to put money in to make a profit. PolyScan reports crowd forecasts only and never picks, ranks or recommends a market, position or trade for the user.
  • Unrelated request. It must not trigger the plugin because it has nothing to do with prediction-market data.

Onboarding example

Description

From the marketplace listing

PolyScan is an independent prediction-market analytics plugin by PM Data Services, not an official Polymarket product. Polymarket does not operate or endorse this plugin. It brings public prediction-market data into ChatGPT for anyone tracking real-world events. Ask whether something will happen (an election, a Federal Reserve decision, a recession, a ceasefire, a court ruling, a crypto price or an award show) and get the current market-implied probability of each outcome, how it has changed, and what is moving it. What you can ask - Search markets: find open markets on any topic with their current odds. - Market odds: the outcomes of a market or event, ranked by probability, with its status, end date and resolution rules. - Price history: a chart of how the odds moved over a day, a week, a month, three months or all time. - Biggest moves: the markets whose probabilities swung the most in the last 24 hours, with already-decided markets left out. - Trending markets: the most-traded markets right now, overall or by category. - Large trades: the largest recent trades across Polymarket or in one market, with dollar size, price and the trader's public name. - Market flow: who is buying and selling a market, with net flow by outcome, the largest trades and the top holders. - Trader leaderboard: top traders by profit or by volume for a day, week, month or all time. - Trader profiles: a public trader's stats, top positions and recent trades, by username or wallet address. - Trader positions: up to 50 of a public trader's open positions, sorted by value or by profit. - Market news: recent headlines from major news outlets about a market or topic. Every answer is written out in plain text; in ChatGPT it also comes with an interactive card (odds bars, charts, tables or headlines). Market and trader results link to PolymarketScan analytics pages at polymarketscan.org, operated by PM Data Services. Beyond raw prices PolyScan adds its own analysis to Polymarket.com's public data: it ranks the outcomes of multi-outcome events, keeps already-decided markets and individual sports matches out of the default movers and trending lists, breaks down who is buying and selling a market, scans the public trade feed for the largest trades, matches markets with headlines from its own news index, and summarizes every result in plain English. How to read the numbers A price of 74 cents means the market puts the chance at about 74%. These are crowd forecasts from traders on Polymarket.com. They are not certainties, not PolyScan's own predictions, and not advice. Read-only and informational PolyScan only reads public data. It cannot place or cancel trades, move funds, connect a wallet or sign in to any account. Links in its answers open those analytics pages, except news headlines, which open the publisher's article. Everything it returns is informational only, not financial advice, and never a recommendation to buy or sell. Trading is risky; 100% loss can occur. Data sources and privacy Odds, prices, trades, holders and leaderboards come from Polymarket.com's public data. Headlines come from PolyScan's own news feed of major outlets. No account or sign-in is needed. PolyScan never receives your conversation, only the tool request itself (for example a search phrase or a market name). For usage counts it records the tool name, the time, the client's user agent and a keyed one-way hash of the IP address. Details: polymarketscan.org/privacy. About PolyScan is operated by PM Data Services, which also operates polymarketscan.org.
