Market context

Polymarket is pricing the KaBuM! Ilha das Lendas vs Vivo Keyd Stars Academy BO5 at 0% YES, so the contract is effectively at the floor today. For holders of the USDC-settled conditional token on Polygon, that means the market is treating a KaBuM! win as not yet reflected in price despite the match being listed as the Circuito Desafiante upper bracket final. The event is scheduled for 26 May, with the market resolving on the series winner rather than map score.

The closest form guide points to KaBuM! as the stronger side. Leaguepedia’s 2026 Circuito Desafiante season page has Ilha das Lendas at 9-0 in the group stage, while Vivo Keyd Stars Academy finished 4-5. That gap matters in a BO5, where a better team can recover from a dropped map more reliably than in a one-game market. Comparable playoff pricing in tier-two Brazilian LoL usually tracks seed and series depth more than brand recognition, and a 0% print often means the order book has not yet caught up with basic bracket information rather than a settled consensus on the result.

The key catalysts are confirmation of the final schedule, any bracket or lane-side changes, and whether both teams actually field their playoff rosters as expected. Sofascore currently lists the series for 26 May at 20:00 UTC, and LoL Esports shows Vivo Keyd Stars Academy with no future scheduled matches under the current filter, which suggests the event may still be pending final publication details. Traders should watch for official playoff updates from Circuito Desafiante and Leaguepedia, because a delay beyond seven days from the scheduled date would determine how the contract settles under Polymarket’s conditions.

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
