Most people think Polymarket arbitrage is dead. They’re wrong. My bot continuously scans hundreds of markets (politics, sports, crypto, geopolitics, culture) looking for the classic inefficiency: YES + NO price summing to less than $1.00. When it finds one, it buys both sides instantly. This pure risk-free strategy has been one of the core engines behind the bot’s $130k+ profit. Even after fees and competition, small edges still appear every day if you have speed and capital.
I’ll break down the exact logic and risk controls in this post.

Cross-Market Logical Arbitrage:
The Strategy That Quietly Printed Money on Polymarket
Body:
Single-market arb is getting harder. Multi-market logical arbitrage is where the real edge lives.
My bot maps relationships between correlated markets (e.g., “Candidate A wins” vs “Party wins”, or sports tournament paths) and flags impossible pricing combinations. It then executes multi-leg trades that are mathematically guaranteed or heavily positive EV.
This approach works across politics, sports, and world events - not just crypto. It’s a big reason the bot crossed $130k in realized profits.
