The real alpha on Polymarket isn't in trying to predict events better than the market -- it's in the market microstructure. Price discrepancies between Kalshi and Polymarket on the same event can persist for minutes because the two venues have different participant bases and settlement rules. Kalshi is USD-settled with KYC, Polymarket is USDC on Polygon with pseudonymous wallets. And because Polymarket's CLOB runs on-chain, you can literally watch competing bots' strategies by tracing their contract interactions.

The part people miss about these 'insider' Polymarket trades is how little capital it actually takes to make these kinds of returns on binary contracts. On most non-headline events the orderbook has maybe 5-10k of depth at the top of book. A new account dropping 50k into a 5-cent yes contract right before news breaks isn't sophisticated -- it's someone with information and a Metamask wallet. The CLOB structure makes it trivially easy to trace these wallets on-chain though, which is arguably better transparency than you'd get in trad finance.

The real issue here isn't just the insider trading -- it's how thin Kalshi and Polymarket orderbooks are on niche events. You can move the price 10-15 cents on a binary contract with a few thousand dollars. That makes insider trading on these platforms both incredibly easy and incredibly profitable compared to traditional securities markets where you'd need serious capital to materially move the price.
