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

Platform comparison

Market context

Yellow Submarine’s best-of-three against Execration is listed for Games of the Future Group A, with independent fixture pages showing a 31 July start at 05:00 UTC, which is the match the market is referring to.[1][13][17] The crowd-implied price of **100% YES** is extreme relative to the broader market picture: Robinhood’s prediction market has Yellow Submarine at **54¢** and Execration at **46¢**, while Leon’s sportsbook line implies a much tighter contest at roughly **58.8%** for Yellow Submarine from 1.70 odds and about **48.8%** for Execration from 2.05.[16][12] That spread suggests the contract is trading well above conventional win-probability estimates.

Recent comparable data also points to caution in reading a perfect-price signal literally. Dota fixtures on event hubs often remain fluid close to start time, and at least one betting listing has already flagged this match as *cancelled* or *postponed*, showing why settlement mechanics matter as much as raw team strength in esports contracts.[7] By contrast, result trackers and match databases still show the fixture as scheduled or live, which means the key distinction for traders is whether the series is actually completed within the contract window, not just whether the pairing appears on a calendar.[1][8][9]

The main catalysts are straightforward: final confirmation that the BO3 starts on schedule, whether any late cancellation or delay is announced, and whether the result is completed before the seven-day fallback threshold built into the market rules. Schedule pages and fixture aggregators have not shown a stable consensus on timing, so traders should watch for official tournament updates rather than rely on a single listing.[1][13][15] If the series does go ahead, any odds drift away from the current prediction-market premium would likely come from lineup news, venue timing, or a start-time change rather than from long-run team reputation alone.

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.
