How to use this market index
Start with category pages
Each category route gives Google and human readers a stable overview page instead of a temporary client-side filter state.
Open canonical market pages
Featured market links point to route-specific detail pages with unique metadata, structured data, venue comparison, and resolution context.
Use venue depth before clicking out
Mantis helps you decide whether to open Polymarket, Limitless, Kalshi, or another venue by surfacing liquidity and market overlap first.
Featured markets
These canonical detail pages are the first URLs we are pushing into search because they are specific, liquid, and materially different from a generic venue browse screen.

FAQ
What is Mantis?
Mantis is a cross-venue prediction market router that searches Polymarket, Kalshi, Limitless, Myriad, SX Bet, and PredictIt simultaneously. Type any question in plain English — "Will France win the World Cup?", "Fed cut before September?", "BTC above $200k?" — and Mantis returns the best-priced market with live odds, liquidity, and a direct link to trade on any venue. No account required to search.
Which prediction market venues does Mantis compare?
Mantis covers Polymarket (largest decentralized venue by volume), Kalshi (regulated US prediction market), Limitless (Gnosis Chain), Myriad, SX Bet (sports), and PredictIt (US politics). The same outcome often trades at 1–8 percentage points difference across venues — Mantis shows all lines at once so you always route to the best price.
Can AI agents use Mantis to trade prediction markets?
Yes. Mantis exposes a full MCP server at mantiss.store/mcp with 5 tools: route_market (find the best venue), get_quote (live yes/no prices), get_arbitrage (cross-venue spread detection), execute_url (attributed trade link), and get_unmet_demand (demand intelligence). Claude, OpenAI, Cursor, and Windsurf agents can connect with a free API key. See mantiss.store/pricing to get started.
Is Mantis free to use?
The web app at mantiss.store is free with no account required. The REST and MCP APIs require a free API key (100 requests/day). Paid tiers — Starter ($29/mo, 10,000 req/day) and Pro ($199/mo, unlimited) — unlock higher rate limits, webhook alerts, L2 order book depth, and fee-normalized spread calculations.
