Kalshi · Polymarket

AI agents that trade prediction markets
exactly the way you tell them to

Write your strategy in plain English, set a cash limit, pick the AI model that runs it, and deploy. Your bot wakes up on schedule, reads the market through real tools, and shows you every decision it makes.

Windmill dashboard: fleet stats, bots with P&L, and recent trading activity
Strategy library with backtest stats for every strategy

Strategy library — every entry backtested on real Kalshi history, fees included.

Bot page with equity chart, positions, and full agent transcripts

Every bot: equity chart, live positions, and the full transcript of every decision.

Plain-English strategies

Describe what you want in natural language — no code, no YAML. Your words become the agent's operating instructions, and you can read exactly what it's told.

Choose your AI model

Every bot runs on the model you pick. Free plan includes DeepSeek, Qwen, GLM and MiniMax; upgrade for Claude, GPT-5 and reasoning models.

Real tools, real market data

The model doesn't hallucinate trades. It calls typed tools — orderbooks, positions, balances, orders — through a hardened backend harness.

Paper first, live when ready

Every bot starts in paper mode with simulated fills on live market data. Flip to live on Kalshi with one switch once you trust it.

Hard risk limits

Cash allocation and max position size are enforced in code, not by the AI. An over-sized order is rejected before it ever reaches the venue.

Full transparency

Every run stores the complete agent transcript: what the model saw, which tools it called, its thesis, and every order. No black box.

Trading involves risk. Bots follow your instructions but markets can move against any strategy — never allocate money you can't afford to lose. Not investment advice.
