Market context
Taiwan’s opposition-controlled Legislative Yuan has already voted to initiate impeachment proceedings against President Lai Ching-te, but the motion failed on 17 May 2026, falling short of the two-thirds majority required for passage. This outcome, confirmed just one day before Lai’s second anniversary in office, has cemented the current 0% crowd-implied probability that he will be impeached by June 30, 2026. The failure was not due to lack of opposition mobilisation; the Kuomintang and Taiwan People’s Party issued top-level attendance orders, yet DPP lawmakers and the opposition’s inability to secure sufficient votes rendered the effort symbolic rather than substantive.
Historically, this is Taiwan’s first presidential impeachment vote, and no precedent exists for a successful case since the island’s transition to democracy. Under the Additional Articles of the Constitution, impeachment requires backing from half of all legislators to initiate, but passage demands two-thirds approval—a threshold the opposition has consistently lacked. Comparable cases in other democracies show that without a clear constitutional crisis or overwhelming public mandate, impeachment motions rarely succeed when the executive retains legislative support. Lai’s refusal to countersign a fiscal amendment, while constitutionally contentious, has not triggered the level of political collapse needed to shift the two-thirds calculus.
Traders should monitor the Legislative Yuan’s scheduled committee reviews on 13 and 14 May, the second public hearing next Monday, and any sudden shifts in DPP-KMT relations. Crucially, the opposition must secure at least 10 additional votes beyond their current 60 to reach the 80-vote threshold. Recent reporting from Focus Taiwan notes the motion remains “largely symbolic,” with no indication of new vote-buying or coalition-building efforts. Until the opposition gains a decisive legislative majority or Lai’s administration faces a no-confidence vote against Premier Cho Jung-tai, the probability of impeachment remains effectively zero.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

- What does Polymarket cost to trade?
- Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.
