Valorant: Team Vitality vs Karmine Corp (BO3) - Esports World Cup Group B

Platform comparison

Market context

The real-world event is a Best of 3 Valorant match between Team Vitality and Karmine Corp at the Esports World Cup Group B, scheduled for 9:45 AM ET on 2 July 2026. In prediction markets, a YES share pays out if the market’s outcome occurs (here, if Team Vitality wins), while a NO share pays out if it does not; the current 100% YES price implies the market believes Vitality will win with certainty.

Historical head-to-heads show Vitality’s dominance in this pairing across titles: in RLCS 22/23 World Championship Semifinals, Vitality defeated Karmine Corp 4–2 to advance to the Grand Finals, while Karmine Corp was eliminated[1]. Though Karmine Corp won 3–1 at the RLCS Paris Major 2026[5], the more recent EWC 2026 Group B match already shows Vitality leading 2–0 with Karmine Corp at world ranking 83 versus Vitality’s 10[2], reinforcing why the market prices Vitality as the near-certain winner.

Traders should monitor the official match completion status, any delay beyond seven days, and whether the match is cancelled or ends in a tie, as these trigger a 50–50 resolution. The live scoreboard on GosuGamers confirms the 2–0 lead as of 15:40 UTC on 2 July[2], and VLR.gg notes Karmine Corp’s 2–1 win in a different EWC match with MVP Suygetsu[4], so verifying the specific Group B outcome is essential. No new roster announcements or patch changes have been reported for Patch 12.05 ahead of this match[6].

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.
