Polymarket hits $176M and Kalshi $108M in record crypto volume on June 2

Polymarket and Kalshi set fresh single-day records in crypto-category volume on June 2, posting $176 million and $108 million, respectively. The surge occurred during a sharp market sell-off that wiped out more than $1.76 billion in leveraged positions and pushed Bitcoin below $67,000, while Kalshi later rolled out Bitcoin perpetual futures on June 3.
