Polymarket bettors now see a 4% chance of a Chinese invasion of Taiwan in the near term, after Japan confirmed Chinese and Russian warships held joint live-fire drills inside its claimed exclusive economic zone in the Pacific. Defense Minister Shinjiro Koizumi disclosed the activity, which Tokyo views as a provocation.
Details of the drills
Japan's defense ministry said the warships conducted the exercises inside Japan's claimed EEZ on Wednesday. The ministry did not specify the exact location, but the area is part of the Pacific Ocean where Japan asserts exclusive economic rights. The drills involved both Chinese and Russian vessels, according to the ministry. Koizumi's disclosure marked the first time Tokyo has publicly confirmed such exercises inside its claimed EEZ this year.
Market reaction
On Polymarket, a decentralized prediction platform, the odds of a Chinese invasion of Taiwan rose to 4% after the drills report emerged. The probability had been at 3% earlier in the week, according to the platform's data. The shift suggests that traders are paying attention to military activity in the region, but the odds remain low, indicating that most bettors do not see an invasion as imminent.
Strategic context
China and Russia have conducted joint military exercises in the past, but the live-fire drills inside Japan's claimed EEZ are a relatively rare event. The Japanese government has regularly protested such incursions, arguing they violate international law. Koizumi's decision to disclose the drills publicly signals Tokyo's growing concern over the military cooperation between Beijing and Moscow.
For now, the odds on Polymarket suggest that the market is not pricing in an invasion as a likely scenario, but the presence of Chinese and Russian warships in Japan's waters keeps the issue on the front burner. The 4% probability is a small but notable increase from the previous level, and further drills could shift the odds again.
