Predexon is the OpenRouter for prediction markets. Prediction liquidity is fragmented across chains, assets, venues, and schemas. Prices move, gaps emerge, but users can’t arbitrage efficiently because every market is siloed across different platforms. Predexon unifies all of it. Here’s what our API enables: - Universal Market Schema: Polymarket, Kalshi, Manifold, Limitless, and more standardized into one ontology - Market Matching Engine: Automatically identifies equivalent markets across venues - Deep Data Layer: Tick-level data, OHLCV, and full historical market coverage since 2020 - Unified Trading API: A single endpoint to route orders anywhere prediction liquidity exists (smart routing, copy trading, and agent primitives coming soon) One API to build terminals, agents, bots, funds, and latency sensitive arbitrage systems across the entire prediction market universe. Prediction markets don’t need more liquidity. They need liquidity you can actually use with size. Predexon makes markets interoperable and whale friendly.

On Polymarket, the price is a blend of everyone trading the market, and it counts a wallet that's been profitable for years exactly the same as one that opened an account today. The number on the screen doesn't tell you who is behind it. Predexon scores every Polymarket wallet on realized/unrealized P&L, fees, ROI, win rate, trade count, and more. so you can pull the skilled money back out of that blend. For any market you set the bar for what counts as skilled, say 15% ROI across 100 or more trades, then look at how those wallets are actually positioned: how many are net long versus short, the average price they got in at, and the volume behind it. That changes what the price tells you. A market sitting at 38 cents looks like a plain 38% chance on its own. But if the wallets with real track records have been buying around 35 and are net long, you are not looking at a neutral 38 anymore. You are looking at a level that informed money already accumulated under. Same price, different trade. You can also run it in reverse and rank markets by where skilled wallets are quietly building positions, so you find them before that flow shows up in the price.

The fastest way to make a prediction-market backtest look better than it is: fill everything at mid. Mid is not a tradable price. It's the halfway point between the best bid and the best ask. If your strategy wants to buy 20k, it doesn't fill at mid, it walks the asks that were actually there. Sometimes the first few levels cover it. Sometimes the trade gets expensive fast. Predexon stores that book for Polymarket. Every time it changes, we snapshot every bid and ask, going back to January 2026. A backtest can replay the book as it was, walk the depth, and answer the only question that matters: what average fill would I have gotten for the size I trade? You get the whole slippage curve, not one number. The endpoint is free and doesn't count against quota. And the live websocket book has the same shape as the snapshots, so the function that made the call in your backtest is the one running in production.
