Polymarket comes under WSJ scrutiny as prediction-market open interest hits record $1.48B

Prediction-market open interest climbed to a record $1.48 billion in the week ending June 15, marking a second straight all-time high, according to a16z Crypto. The metric tracks the value of active bets still open, rather than daily buying and selling reflected in trading volume. The record comes as Polymarket faces questions over its marketing practices and how it presents itself.
