Polymarket has listed a market titled “2026 Taiwan Local Elections: Party Winner.” The page currently shows 88% of funds backing the KMT to win the most mayoral seats in the November 28 elections, while the DPP stands at 12%. The market, though, has recorded less than $30,000 in total volume, leaving prices highly sensitive to a small number of trades.
Low volume makes the headline odds less convincing
Polymarket drew broad attention during the 2024 US election cycle, when its presidential election markets reached $3.68 billion in volume. Against that benchmark, the Taiwan market is tiny. With liquidity this thin, a handful of orders can move implied probabilities sharply, so the current 88% reading says more about existing positioning than about a deep, broad market consensus.
Settlement is based on seats won, not total votes
The contract does not settle on nationwide vote share. Under the rules cited in the source material, the winning outcome will be the party whose officially nominated candidates secure the most seats across Taiwan’s 22 mayoral and county magistrate races. Victories by independent candidates do not count toward any party.
If the seat count ends in a tie, the rules call for the result to be decided by alphabetical order of the parties’ English names. In the example noted by the source, KMT comes before DPP, which means the contract structure itself could affect settlement in a deadlock scenario.
Taiwan users face more than trading losses
For Taiwan-based users, the bigger issue may not be market risk. The source says Polymarket has explicitly stated that it does not open the service to users in Taiwan. Even so, permissionless blockchain infrastructure means access may still be technically possible.
The legal exposure is more serious. The source cites Article 88-1 of Taiwan’s Public Officials Election and Recall Act, which says gambling on election outcomes through the internet can carry up to six months of imprisonment, plus fines ranging from NT$100,000 to NT$1 million. Penalties can be heavier for those who provide venues or organize group gambling. The same source says Taiwan’s High Prosecutors Office has treated election betting as illegal, and past cases and prosecution standards have placed prediction markets in that category.
On-chain activity can still be traced back to real identities
The report also points to enforcement history. During Taiwan’s 2023 presidential election period, police reportedly deployed more than 70 officers in a nationwide operation and arrested 17 people suspected of using Polymarket for election betting. According to the source, investigators traced on-chain transactions to addresses linked to centralized exchanges, then used KYC records to identify individuals. A wallet address may appear pseudonymous, but that protection can weaken fast under legal scrutiny.
Prediction markets are also facing insider-trading scrutiny
Regulatory pressure is not limited to Taiwan. The source says US prediction market Kalshi recently disclosed its first insider-trading cases. One involved an editor for MrBeast, who was fined $20,000 and banned for two years for trading on non-public information. A former California gubernatorial candidate received a five-year ban.
The source also notes that Democratic members of Congress in the US have introduced the “Financial Prediction Market Public Integrity Act of 2026,” a proposal that would bar elected officials and government insiders from trading political prediction markets.
