Did Thailand strike Cambodia?
Market Background and Criteria
On May 28, 2025, a Cambodian soldier was killed during a clash with Thai troops in the disputed Emerald Triangle, a remote border region where Cambodia, Thailand, and Laos meet. Both sides accused the other of crossing into contested territory, and tensions steadily escalated in the weeks that followed. Relations between Thailand and Cambodia have been tense for decades, due to recurring border conflicts, long-standing political friction, and military standoffs.
The conflict intensified in July after landmine blasts along the border wounded several Thai soldiers on July 16 and again on July 23. Thailand responded by downgrading diplomatic ties with Cambodia and, according to analysts and satellite imagery, repositioning missile units closer to the frontier. On the morning of July 24, gunfire and artillery were reported along the border.
On July 24 at 1:00 PM ET, with the threat of escalation looming, Polymarket launched the markets Thailand strikes Cambodia by Friday, July 25? and by July 31?
For the market to resolve "Yes," Thailand had to initiate a drone, missile, or air strike on Cambodian soil or any Cambodian embassy or consulate between July 24 at 1:00 PM ET and July 25 at 11:59 PM ET. The strike had to be confirmed by the Thai government or a consensus of credible reporting. Intercepted drones, surface-to-air fire, or ground-based attacks didn't count. If no qualifying strike occurred within that window, the market would resolve to "No."
For the purpose of this case study, we focus on the July 25 market, as the July 31 version was not subject to dispute.
Price Movement and Trader Reaction
When the market opened on July 24, "Yes" shares traded between 25¢ and 60¢ as traders weighed the possibility of a Thai air or drone strike occurring within the narrow resolution window. Despite active fighting along the border, there was uncertainty over whether any strike would meet the market's strict criteria before the Friday night deadline.
On July 25, as the market approached expiration with no confirmed qualifying strike, confidence collapsed. Prices fell sharply, reaching a low of 5¢ just as the market deadline passed. Most traders appeared to believe the window would close without a valid strike.
After the market deadline passed, most traders believed the resolution criteria had not been satisfied, and someone proposed "No" as the outcome.
However, the decision sparked discussion in the community, and just six minutes before the proposal was set to be accepted, it was disputed.
A sudden price surge followed, with "Yes" shares jumping from 5¢ to 14¢, a level they held as the market neared final expiration.
Five hours later, the market was proposed as "No" again, but it was disputed once more.
The controversy sparked more structured discussion, with the price ranging between 15¢ and 40¢. However, around noon, the price spiked from 12¢ to 99¢.
This sudden shift laid the groundwork for what became the Thailand strikes Cambodia dispute, as both sides clashed over whether the evidence met the required standard of confirmation.
