The extension is also known as PMs4X. Use it beside relevant content, then open a suggested market to examine the actual outcome and deadline. A topical connection is not necessarily a match to the post’s precise claim: a contract can ask a narrower or different question. The store describes a focused discovery extension rather than a separate analytics dashboard or documented order-execution system. It is a browser extension, not a standalone mobile app. The developer declares that account data is not collected or stored; that is the developer’s privacy statement. ### Who it is for - Users who find news and market ideas while reading X. - Readers who want a shorter path from a post to a relevant contract. ## Browser tools and permissions - **Post-to-market matching** Find Polymarket questions connected with an X post and inspect them while the original content is still available. - **In-feed discovery** Invoke the extension’s control during X browsing instead of repeating the topic in a separate manual search. - **Chrome installation** Use the published Chrome Web Store installation listing. - **Developer privacy statement** The developer states that account data is not collected or stored. ## Browser workflows ### Follow a news lead Inspect the suggested market as a route back to the underlying contract. Read the post that prompted it, then open the contract’s exact question and deadline before taking the match further. ### Verify the connection Judge the suggestion against the claim actually made in the post. A related subject can still lead to a different outcome question, so compare the outcome wording before calling it the same event. ## Pricing and total cost The store offers an Add to Chrome installation path but does not publish a subscription or trading-fee schedule. ## Installation and permissions 1. Install from the official Chrome Web Store listing. 2. Open X in the supported browser. 3. Use the market-discovery control beside relevant content. 4. Open a proposed Polymarket market and read the question and rules. ## Useful links ### What to check - A related topic can differ from the precise claim in a post. - Automatic order execution is not documented in the store description. - This is a browser extension rather than a standalone mobile app. A closer look ## Ratings & reviews Editorial rating **3.0**/ 5 0 user reviews PredictionToolkit editorial ### Our take on Prediction Markets for X Editorial rating: 3/5.
