Paradigm says Polymarket trading volume may be inflated by double-counting error

Cryptocurrency investment firm Paradigm has analyzed that trading volume on the prediction market platform Polymarket may be inflated due to a double-counting error. According to Cointelegraph, Paradigm researcher Storm explained that Polymarket's complex on-chain data structure has caused many analytics tools to adopt flawed accounting methods. The researcher stated that major dashboards such as DeFiLlama, Allium, and Blockworks are double-counting single transactions by summing them from the perspectives of both the maker (sell-side) and the taker (buy-side).
