Yes 11.8%
Polymarket and Kalshi agree within 1 point on every outcome.
Fair chance strips out each venue’s built-in margin (its prices add up to more than 100%), then blends the venues by how much has traded there, so the outcomes add up to 100%. Best Yes price is the cheapest ask across venues, and the payout is what a winning $100 stake returns before fees. Open a row for each venue’s contract name, bid and ask, and how closely their rules match.
Prices come from our regular polls of each venue, the oldest 5 min ago. Ages are as of when this page was built.

Labels suggest the same named outcome; no persisted outcome identity or settlement parity is verified.
Indicative only, prices are 5 min old: No arbitrage: the best bid elsewhere is 10¢, at or below the cheapest ask of 13¢.
No cross-venue arbitrage right now: on every matched outcome, the best bid on one venue is at or below the cheapest ask on the other. Find markets with open spreads

Live prediction market odds for "FTC opens investigation into AI book destruction in 2026?". Yes leads at 11.8%. $9K has traded across 1 outcome on Kalshi and Polymarket. The market is expected to resolve by Jan 1, 2027.
This market will resolve to "Yes" if the United States Federal Trade Commission (FTC) publicly announces or confirms that it has opened an investigation, issued orders under Section 6(b) of the FTC Act, or filed an enforcement action concerning the acquisition, scanning, or destruction of print books by AI companies for use in training AI models (the "book destruction practice"), between market creation and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". On August 21, 2026, a coalition of 18 civil society groups, including Demand Progress Education Fund, the Consumer Federation of America, and the Institute for Local Self-Reliance, asked the FTC to investigate whether the bulk purchase, destructive scanning, and disposal of print books by AI companies (the practice described in the copyright litigation Bartz v. Anthropic) constitutes an unfair method of competition under Section 5 of the FTC Act, including through the FTC's Section 6(b) study authority. An AI company means any company that develops, trains, or operates AI models, and includes a contractor or vendor that acquires, scans, or disposes of print books on such a company's behalf. An investigation into any one of the steps of the book destruction practice (the bulk acquisition of print books, their destructive scanning, or the disposal of the books) qualifies, provided it concerns print books acquired or processed by AI companies for use in training AI models. A qualifying act is a public, on-the-record act of the FTC confirming an investigation into the book destruction practice, namely one of the following: an official FTC press release, or an official statement published by the FTC on ftc.gov or through the FTC's official accounts; an order issued under Section 6(b) of the FTC Act to one or more AI companies, publicly announced or published by the FTC, that concerns their acquisition, scanning, or destruction of print books; an administrative complaint or federal court complaint filed by the FTC concerning the book destruction practice; any other publicly available filing by the FTC in a federal court or in an FTC administrative proceeding that confirms such an investigation (for example, a petition to enforce a civil investigative demand); or an on-the-record statement by the FTC Chair or an FTC Commissioner, including in congressional testimony, confirming that the FTC has opened or is conducting such an investigation. The qualifying act need not name a specific company, need not use the word "investigation", and need not state that the books were or are to be used for AI training, provided it confirms that the FTC has opened or is conducting a formal investigation, study, or enforcement proceeding whose subject includes AI companies' acquisition, scanning, or destruction of print books. An investigation that also covers other conduct qualifies so long as the acquisition, scanning, or destruction of print books by AI companies is expressly identified in the FTC's public announcement, or in the published text of the order, complaint, or filing, as a matter under investigation. The following will not qualify: statements of general concern about the book destruction practice; a request for public comment, a workshop, or a report that does not confirm an investigation; an acknowledgement that the FTC has received or is reviewing the coalition's letter; an FTC investigation or Section 6(b) study of AI companies on other matters (for example AI partnerships, chatbots, or consumer protection) whose public announcement and published text do not expressly cover the acquisition, scanning, or destruction of print books; an investigation limited to the acquisition or use of digital copies of books (for example pirated or shadow-library files) that does not concern print books; investigations by other federal agencies, state attorneys general, or foreign regulators; and anonymous, unattributed, or leaked reports that the FTC has opened an investigation, unless publicly confirmed by the FTC by the deadline. Statements that the FTC is considering, reviewing, monitoring, or looking into the book destruction practice, or that it may investigate it, will not qualify unless they explicitly confirm that an investigation has been opened or is underway. If the FTC opens an investigation but does not publicly confirm it by December 31, 2026, 11:59 PM ET, this market will resolve to "No". Once a qualifying act has occurred, this market will resolve to "Yes" regardless of whether the investigation is later closed, narrowed, or results in no enforcement action. The primary resolution source for this market will be official information from the Federal Trade Commission (https://www.ftc.gov/news-events/news/press-releases); however, a consensus of credible reporting may also be used to confirm that a qualifying public act has occurred.
It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.
A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.
Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.
Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.
