Recently, I developed an arbitrage strategy for prediction markets, mainly targeting the same thematic events on the Opinion and Polymarket platforms.

After going live for a while, to be honest, getting rich quickly is not very realistic, but controlling drawdowns and steadily earning some points is quite reliable.

The core logic is as follows:
1. Capture market data for the same prediction topics on both sides.
2. Automatically distinguish between binary markets and multi-choice markets
3. Real-time monitoring of the price differences between the two platforms to capture arbitrage opportunities.
4. Evaluate how large an order can be absorbed based on market depth.

In simple terms, it is about finding pricing discrepancies on both sides, buying low and selling high within the limits of liquidity. The prediction market is actually quite suitable for cross-platform Arbitrage, as price differences often occur; the key is to have tools to monitor it automatically.
