Polymarket US and Kalshi offer near-identical taker profits on 100-contract trade

The near-identical headline profit figure is less informative than the caveats buried in the analysis: resting orders and account-funding method can both shift the comparison, which means the apparent parity reflects a specific taker scenario rather than a general pricing equivalence. For traders choosing between the two venues, execution style and the cost of moving money in may matter more than the quoted profit on a single round trip. Whether the parity holds once maker fills and funding routes are factored in is the open question worth watching.
