XMarket Composer

Recommend prediction markets while composing posts on X.

XMarket Composer helps writers add prediction-market context while composing posts on X. When you write a prediction, the extension can match your draft to relevant Polymarket and Kalshi markets, show current market probabilities, and insert a shareable XMarket citation link into your post. The citation page gives readers more context, including the market source, current odds, selected outcome, volume, end date, and an information-only link to view the live market. XMarket is built for creators, analysts, researchers, newsletter writers, and readers who want clearer market-backed context around public forecasts. Key features: - Detect prediction-ready drafts in the X composer. - Search for related prediction markets. - Compare market probabilities before posting. - Insert a clean citation link into your X post. - Save citation snapshots for creator records. - Support Polymarket and Kalshi market context. XMarket is information-only. It does not connect wallets, place trades, route orders, custody funds, or provide financial advice.
