Market context

South Korea will hold municipal elections on 3 June 2026, with Busan's mayoral race among the most closely watched contests. The current crowd-implied probability of 18% for the listed candidate reflects significant uncertainty about the eventual winner, with multiple potential contenders still positioning themselves ahead of the formal campaign period. Busan, as South Korea's second-largest city and a major port hub, carries substantial political weight; the mayoral seat has historically served as a springboard for national-level ambitions.

Previous Busan mayoral elections demonstrate how volatile these contests can be when incumbent parties face demographic shifts or local grievances. The 2022 local elections saw the conservative People Power Party gain ground nationally, though regional dynamics in Busan—traditionally competitive between conservative and progressive factions—often diverge from national trends. The 18% probability suggests the market is pricing in either a fragmented candidate field or genuine uncertainty about which faction will consolidate support, rather than a clear frontrunner emerging from either major political camp.

Key catalysts include formal candidate registrations, which typically occur within weeks of the election date, and any major policy announcements from Seoul regarding port development or regional investment that could shift local sentiment. The National Election Commission will manage the official process; traders should monitor Korean-language reporting from outlets such as Yonhapnews and local Busan media for shifts in candidate positioning. The resolution deadline of 31 January 2027 allows sufficient time for official certification, though any legal challenges to results could create ambiguity before that date.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.

FAQ

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does it cost to trade on PolyGram?

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
