China vows countermeasures over Taiwan tip site as Polymarket invasion odds slip

China Condemns Taiwan’s Tip-Reporting Website as Polymarket Cuts 2026 Invasion Odds to 6.45%

China said it would take countermeasures after Taiwan launched a new website for Chinese nationals to submit intelligence tips, stepping up the war of words over cross-strait security. On Polymarket, traders slightly marked down the chance of a China invasion of Taiwan by the end of 2026 after the latest exchange.

Key Takeaways

Polymarket prices a 93.55% chance of No and a 6.45% chance of Yes on a China invasion of Taiwan by end-2026.
Odds fell 1.00 percentage point as Beijing condemned Taiwan’s new tip-reporting website and warned of legal action.
The contract resolves on 2026-12-31, with $35,180,763 in total volume so far.

China said it would take countermeasures in response to a new Taiwan government website that allows Chinese nationals to report intelligence tips, calling it evidence of Taipei’s “confrontational mindset.” Taiwan’s National Security Bureau unveiled the site on Sunday, saying it offers a secure channel for a growing number of people who are dissatisfied with China’s system and want change. At a regular news conference in Beijing, Taiwan Affairs Office spokesperson Chen Binhua accused Taiwan of “intelligence theft, infiltration, and sabotage” and said authorities would act, without giving details. Chen also said Chinese citizens, organizations and companies have an obligation to safeguard security and warned that those who provide intelligence to Taiwan in a way that constitutes a crime would face legal responsibility. Taiwan said the program follows approaches used by agencies in countries including the United States, Britain and Israel, while reiterating that it rejects Beijing’s sovereignty claims.

Polymarket Data: $35.18M Volume as “No Invasion by End-2026” Holds at 93.55% After 1-Point Dip

The Polymarket contract “Will China invade Taiwan by end of 2026?” was last priced at 6.45% for Yes versus 93.55% for No. That marks a 1.00 percentage-point drop from the prior 7.45% Yes price in the provided snapshot. Total traded volume stands at $35,180,763, indicating deep liquidity even as the market remains heavily skewed toward a No outcome. The 24-hour and 7-day changes in the provided history summary were both 0.0, signaling limited recent follow-through beyond the latest move.

Any further statements from Beijing’s Taiwan Affairs Office or Taiwan’s National Security Bureau about enforcement, arrests, or new countermeasures could test whether the market’s low-probability invasion pricing holds into the 2026-12-31 resolution.
