I checked the arbitrage amount increase of prediction markets @Polymarket and @Kalshi in the past two days, and found that the probability differences for several events are quite large, such as the Louvre, Fed interest rates, etc. I plan to research further.

This is my 7th article on learning arbitrage.

Arbitrage directions in prediction markets:

1. Cross-platform arbitrage on the same event: Trump winning, btc>100k, Fed rate cut

Arbitrage profit - kalshi fee 1% - gas fee = actual profit

2. Polymarket single platform: yes + no price deviation, winning semi-finals and championship related events, finalizing near-expiry certain events.

Real-time price difference scanning idea:

Connect 2 platforms web3 socket

Event matching

Price difference

Automatic order placement

Reminder: Don't gamble
