What PredictEngine does
No-code bot builder that hosts and runs Polymarket strategies for you. You describe a rule in plain English — “buy BTC UP when it dips below $0.40” — or pick a template, and the platform writes the bot, provisions a dedicated Polygon wallet, signs the orders and keeps it running 24/7 on its own infrastructure, with a dashboard, a Discord bot and a mobile terminal to watch it. Templates cover single-side entries, cross-market arbitrage, copy trading that mirrors chosen wallets, market making and sports value against bookmaker lines; a marketplace lets users publish bots for others to run. The free plan runs five live bots; $9 a month unlocks the AI builder, 25 bots and backtesting; $49 adds an unlimited builder and 25% lower trading fees. The docs list Limitless and Predict.fun alongside Polymarket. The wallet is generated and encrypted on their side and the private key is exportable at any time.
Features- Plain-English bot builder plus a visual builder and a template library; bots deploy in minutes and run on hosted infrastructure
- Strategy types: single-side rules, cross-market arbitrage scanning, copy trading of chosen wallets, market making, sports value
- Dedicated Polygon wallet per user — send POL and it is converted to USDC automatically; card and Apple Pay deposits; no KYC
- Backtesting from the Starter plan, a public strategy marketplace and a leaderboard of bots with opt-in public profiles
- REST API and an MCP server for programmatic access; a Discord bot that provisions an account and wallet on first use
- Everything runs on their servers: the wallet is created for you, the key is AES-encrypted at rest and the bot signs with it. The terms say funds stay in your individually owned wallet with no pooled balances and that you can export the key any time — and, in the Discord section, call the same thing a custodial wallet. Treat it as keys on their server.
- The front-page numbers — $2M+ volume, about $20K in user profit, 10K+ bots, 1M+ trades — are the vendor's own counters; the public leaderboard promises trades verified on-chain but renders no rows without an account, and the live-activity ticker on the landing shows illustrative fills.
- Templates make it easy to launch an arbitrage or market-making bot with no idea what edge it has. Backtesting is gated to paid plans, so the free tier trades real markets with no way to test first.
