arbitrage between @opinionlabsxyz and @Polymarket

prediction markets often disagree on probabilities for the same event

how it works in practice:

> find the same event on both platforms

> check YES price on one side and NO price on the other

> if YES + NO < 1.00 spread exists

there’s a tool designed specifically to help spot these kinds of discrepancies:

how the tool actually works:

> it automatically matches identical events between Opinion and Polymarket

> parses live orderbooks (not just last traded price)

> lets you choose bid / ask / mid mode

> calculates whether YES on one side + NO on the other creates a spread

> checks liquidity depth so the setup is executable

> lets you set your budget and calculates exact share sizing

instead of manually calculating anything, the tool shows:

> how many shares to buy on each platform

> how much capital goes to each leg

> payout if YES wins

> payout if NO wins

> net locked spread
