Market context

The Circuito Desadiante Playoffs grand final pits Vivo Keyd Stars Academy against KaBuM! Ilha das Lendas in a best-of-five League of Legends match originally scheduled for 1 June at 21:00 UTC. This represents the culmination of Brazil's secondary competitive circuit, where academy rosters and challenger organisations compete for regional recognition and qualification pathways. The match settlement window extends to 2 June at 02:15 UTC, allowing a seven-day buffer for rescheduling before the market resolves to a tie condition.

The 100% implied probability reflects the structural certainty of match completion rather than predictive confidence in either team's victory. Brazilian esports infrastructure has demonstrated reliable fixture delivery across the Circuito Desafiante's recent seasons, with cancellations or extended delays remaining uncommon. However, traders monitoring conditional orders should flag potential schedule shifts tied to broader CBLoL calendar adjustments or unforeseen technical incidents at the broadcast venue. The academy circuit typically operates with less scheduling flexibility than mainline competitions, making venue-dependent delays a material risk factor for positions held through the settlement window.

For programmatic traders, this market's utility lies primarily in arbitrage detection rather than directional play. The binary outcome structure—resolving either to a team victory or tie condition—creates straightforward conditional logic for bot implementation. Monitor official CBLoL announcements and Vivo Keyd Stars Academy's roster status updates in the 48 hours preceding the scheduled start, as last-minute player availability issues have historically triggered fixture delays in Brazilian academy play.

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.
