Dota 2: Yellow Submarine vs Vici Gaming (BO3) - Games of the Future Group A

Platform comparison

Market context

Yellow Submarine’s best-of-three against Vici Gaming in the Games of the Future Group A was live on the scheduled slot, and the market’s 0% YES price sits well below the broader platform and analyst read on the contest. Polymarket’s own market page framed Vici as the clear favourite, citing implied win probabilities of roughly 74-88% across prediction platforms, while Strafe listed Vici only modestly ahead in its Dota 2 world rankings, at #19 to Yellow Submarine’s #25.[4][7]

The historical frame does not support a zero-probability view. Yellow Submarine won 2-0 in their opening match at the event, and Vici Gaming had also opened Group A with a comeback win over Amaru, before a heavier run of results elsewhere included losses to Falcons and Team Yandex.[14][1] On form alone, the comparison points to a favourite rather than a lock: Yellow Submarine entered with three wins from its last five on Strafe, while Vici had two from five, so a short BO3 carries genuine upset risk even when one side looks structurally stronger.[7][15]

For traders, the main catalysts are not roster rumours but tournament mechanics: confirmed start time, whether the series remains on schedule, and whether the organisers update the bracket or move the match window. Flashscore and Sofascore both carried the fixture as a live event on 1 August, which matters because if the match is not played, is abandoned, or drifts beyond the settlement window without a winner, the contract resolves 50-50 rather than to either side.[2][5]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.
