HIGHEST VOLUME MARKETS

Leading the pack in terms of trading volume is the market on whether a permanent peace deal between the US and Iran will be reached by May 31, 2026. Despite a 0.0% probability, this market has amassed a staggering $87,888,981 in trading volume on Polymarket.

NOTABLE PROBABILITY SHIFTS

Several markets have experienced significant probability shifts. The likelihood of Lane Johnson announcing his retirement before the 2028-29 NFL season has reached 21.0%, reflecting recent developments or speculations within the sports community. Similarly, the probability of an 8.0 magnitude earthquake in California before 2035 stands at 27.0%, driven by ongoing discussions about seismic activity in the region.

Ethan Holliday's potential debut in MLB has two markets with differing timelines. The probability for him playing before November 1, 2029, is at 49.0%, while a more optimistic scenario for August 1, 2030, stands at 69.0%. These shifts suggest varying expectations about his career trajectory.
