Overview
Free research and practice site for prediction markets. A public scanner lists about 4,200 open Polymarket markets with price, 24-hour change, total volume and closing date, filterable by category, price, volume and close; with a free account you can follow markets, paper trade them at live prices with no money at stake, group trades into strategies, note the reasoning behind each position and review the record in a journal.

The site is running in what it calls recovery: Kalshi coverage, email notifications and paid plans are paused, and the scanner shows a delayed cache.
How it works
- A tool for doing the homework, not a bot: it finds markets, lets you rehearse a trade with no money down and keeps an honest record of how your calls turned out. Market links send you to Polymarket to trade for real.
- The scanner's prices match the exchange. On Oct 24, 2026 its Yes 5% / No 96% for J.D. Vance leaving the vice presidency by Dec 31, and Yes 7% / No 95% for Vance ruling out a 2028 run, were Polymarket's own asks on both sides, rounded — so Yes and No add up to a little over 100%. The data is delayed, though: that morning the cache was about an hour and a half old against the site's own 10-minute target, and its health check reported it as stale.
- The expert network is a plan, not a feature yet. The site's tagline speaks of knowledge from verified experts; its own About page says it is still building that network and will start publishing expert work later, and Pro's credits are for expert content “as it launches.”
- Young and anonymous. The domain was registered on Jul 29, 2026, the site names no person or company, its terms fall under Hong Kong law, and the only contacts are hello@chironus.com and @askchironus on X. With no payments and no wallet involved, the risk is limited to the email address you sign up with.
Supported markets
- Polymarket (all categories)
- Kalshi (listed on the site, paused when we checked)
Free account: follow up to 10 events, 5 open paper positions and 5 paper trades a day, journal and history kept for 30 days, weekly digest. The scanner needs no account. A $20/month Pro plan is listed for unlimited follows, real-time alerts and credits for expert content, but its checkout is paused, so nothing can be bought today. Information product — no funds held, no trades executed.

Chironus alternatives
Prediction Hunt
Odds aggregator and tools directory for prediction markets. Compares side-by-side pricing for the same market across Polymarket, Kalshi and PredictIt to surface arbitrage, and hosts a community-curated directory of prediction-market tools.
Dome
Prediction-market APIs and SDK for developers. One integration for Polymarket and Kalshi data — historical order books, real-time trade webhooks and WebSockets, and backtesting — via REST plus TypeScript and Python SDKs.
Kairos
Cross-venue trading terminal that merges Kalshi, Polymarket and Predict.fun into one order book. Matching contracts on different exchanges are shown as a single instrument with a composite ladder and a global best bid and offer, so you can see which venue is actually cheapest before you send, and an order to the NBBO endpoint routes to whichever book shows that price. Feeds are ingested next to the venues and merged in the browser with no polling interval; the ticket carries GTC, GTD, FOK, FAK and IOC time-in-force, post-only and slippage caps, with batch cancel and a per-venue kill switch. A bots panel runs parameterised templates — market making, cross-venue arbitrage, dip buying — against recorded books first and promotes the same config to live. The same engine is exposed as a REST and WebSocket API with scoped keys, IP whitelisting and a free read-only market-data tier. Built by a team from high-frequency trading firms and exchanges and backed by a $2.5M seed led by a16z.
