Monitoring by the Svmuu Seer Channel shows that a two-week-old address spent $52,000 to buy "No permanent peace agreement between the US and Iran reached before May 15," while also making a small purchase of "No permanent peace agreement reached before May 31." This address had previously only bought two events: "No permanent peace agreement reached" on April 22 and April 30.
The Svmuu Seer Channel continues to monitor the prediction market, seeing changes before pricing.
