Priced is a Chrome extension that brings real-time prediction markets directly into your X (Twitter) feed. It matches tweets to live Polymarket predictions and lets you trade on-chain through Jupiter on Solana. The extension uses intelligent semantic matching to detect tweets about real-world events and embeds interactive trading cards right below the tweet. Trade YES or NO shares without ever leaving your feed.
