    Chrome Extensions for Prediction Markets: What's Changing Aug 1

    Google added predictive markets to Chrome Web Store prohibited products. Enforcement starts August 1, 2026 — here's what that means for traders.

    Quick Summary

    The key takeaway from this page

    From August 1, 2026, Chrome Web Store will enforce a ban on extensions that facilitate or enable real-money prediction market transactions. Official websites and apps still work. Use platform sites or this aggregator instead of store extensions for trading.

    What Google announced

    On July 1, 2026, Google published Chrome Web Store policy updates that expand Regulated Goods and Services language to predictive markets: extensions that "facilitate or enable real money transactions on predictive outcomes are not allowed." Enforcement begins August 1, 2026.

    Deadline

    Developers were told to review listings before August 1. After enforcement starts, out-of-compliance extensions may face Chrome Web Store action, including removal.

    What's affected

    Trading / order-entry extensions

    Extensions that place, edit, or cancel real-money prediction market orders from the browser toolbar or a side panel.

    Wallet / deposit helpers tied to real money

    Tools that move cash or crypto into prediction markets as part of the extension's purpose.

    One-click bet / arb bots in Chrome

    Any Chrome Web Store listing that facilitates real-money transactions on predictive outcomes — Google's exact policy language.

    What isn't affected

    Prediction market websites

    Kalshi, Polymarket, PredictIt, and similar sites in a normal browser tab are outside Chrome Web Store policy. Open the site directly.

    Mobile and desktop apps

    Native apps and progressive web apps are not Chrome extensions. Store policies for iOS/Android and desktop installs are separate.

    Read-only / paper tools (if clearly disclosed)

    Extensions that only show odds or simulated paper trading without real-money transactions are not the target of the new regulated-goods language — confirm the listing still complies with data and disclosure rules.

    This site and other aggregators

    Comparing odds, fees, and liquidity in a website (like PredictionMarkets.US) is not a Chrome extension distribution channel.

    What to use instead

    If an extension you relied on disappears from the store, switch to first-party surfaces or a comparison site — you do not need a Chrome Web Store listing to trade.

    Use the platform in a normal tab

    Trade on the official site or app for each venue — no extension required.

    Compare markets here

    Browse live events and cross-platform prices without installing store extensions.

    Spot price gaps without bots

    Scan cross-platform spreads in the browser; you still execute on each venue's own site.

    Why this matters

    Store bans are not the same as a CFTC product ban. Google is drawing a line for

    extensions
    that sit between you and real-money event contracts. Pair that with ongoing U.S. regulatory fights over event contracts — but do not confuse a Web Store policy with a nationwide trading ban.

    Prefer official platform UIs and well-known websites over unsigned sideloaded extensions that claim to "bypass" the store ban — those often create security and account risk.
