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

Platform comparison

Market context

Yellow Submarine’s BO3 against Execration in Games of the Future Group A is listed for 05:00 UTC, with some fixtures pages showing a slightly later local listing but the same underlying match-up and format. Official-style schedules and match trackers agree that this is a group-stage Dota 2 series, so the market is mainly about whether the game actually starts and finishes cleanly, rather than a long-running tournament uncertainty.[1][5][15][20]

The current **100% YES** crowd price looks much more absolute than comparable books. On Robinhood-style prediction markets, the same event was trading around 54¢/46¢, which implies a narrow Yellow Submarine edge rather than certainty.[17] Traditional bookmakers show the same direction but with decimal odds: Leon quoted Yellow Submarine at 1.70 and Execration at 2.05, which translates to a market expectation closer to the mid-50s once the bookmaker margin is removed.[14] That gap is typical: prediction markets quote a direct probability, while sportsbooks express price plus vig, and access also differs because sportsbooks and some exchange-style books require broader KYC and jurisdiction checks than many prediction markets do.

For traders, the key catalysts are not team names but event execution. If the stream is live and the series is completed, the market should settle on the winner; if the match is cancelled, tied, or delayed beyond seven days, it resolves 50-50 under the rules. The main things to watch are last-minute schedule changes from the tournament operator, whether the series begins on time, and whether a walkover or partial-play situation appears on live scoreboards such as SofaScore or Flashscore, which can move a market from full-match binary pricing into the event-handling rules very quickly.[1][5][8]
