Prediction markets price the same event differently.
That gap is your edge, and Arbitrex helps you catch it.
Web3 ↔ Web3 (PM-PM) • Web2 ↔ Web3 (Cross-Arb)
How it works
Prediction markets independently price the same real-world event, and they rarely agree on the probability.
Our scanner watches 5 platforms 24/7. When combined YES+NO prices fall below 100% (Web3↔Web3) or when prediction market odds diverge from bookmaker lines (Web2↔Web3), an arbitrage window opens.
Web3↔Web3: Buy YES on one PM, NO on another. Web2↔Web3: Bet opposite sides on bookmaker vs PM. No matter the outcome, you collect the spread. The math guarantees it.
Under the hood
Finding real arbitrage means solving two problems: which markets on different platforms are about the same event, and how confident are we?
We compare markets across all platform pairs (hundreds of millions of potential combinations) using fast text similarity algorithms. This filters the pool down to a manageable shortlist of candidates where a real match is plausible.
Each candidate pair is validated by AI that reasons about whether the two markets truly describe the same event. It returns a confidence score; only high-confidence pairs are promoted to the live arbitrage scanner.
