Why BetSync?
BetSync lets traders treat prediction markets like ETF-style exposure. It finds the best odds across multiple platforms and maintains a single, unified position.

Best Odds Routing
Route size to the platform offering the most favorable price while respecting liquidity and limits.
Auto Rebalancing View
See how odds shift over time and how a unified probability compares to each individual market.
Single Close Action
Close or reduce your exposure from one interface instead of unwinding multiple tickets across platforms.
BetSync reads odds and liquidity from multiple venues to construct a single, unified probability and suggested allocation.
About BetSync
BetSync is built for traders who believe prediction markets are powerful but fragmented. Instead of picking a single venue, BetSync treats each platform as a source of information and routes exposure across them.
By monitoring odds, spreads, and liquidity on Polymarket, Kalshi, Betfair, and Manifold, BetSync constructs a unified probability and allocation strategy. Traders see one position, one probability, and one risk profile—backed by multiple markets working underneath.
