Polymarkt trading

Hey everyone,

I have access to the Pinnacle API and I'm trying to figure out a way to use it to spot value by comparing it against markets on Polymarket.

The basic idea: Pinnacle is generally considered a sharp book, so I want to treat their odds (de-vigged into "true" implied probabilities) as a baseline, then compare those against the prices on equivalent Polymarket markets. Where the two disagree enough, there might be value — either on Polymarket or as an arb.

Would appreciate any input from people who've tried comparing a traditional sharp book against prediction markets. Thanks!
