PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both platforms apply identical completion thresholds, source hierarchy, and edge-case handling for all market types (match winner, map winners, round totals, handicap, games played).Primary resolution logic: Official HLTV.org; credible reporting and video evidence if HLTV.org results unavailable within 2 hours of event conclusion.

Core resolution logic:

  • Match winner resolves to the team winning 2 maps in the BO3; if match begins but incomplete due to opponent forfeiture/disqualification/walkover, the winning team is declared; if match is canceled, ends in tie, or delayed beyond 7 days without winner, resolves 50-50.
  • Individual map winners (Map 1, Map 2) resolve based on the team winning that map if completed; if map is not completed or decided by forfeit/disqualification/walkover, resolves 50-50.
  • Map round totals (Over/Under 21.5) resolve based on combined rounds played if the map is completed to a final round score; if map is not played, not completed, or decided by forfeit/disqualification/walkover, resolves 50-50.
  • Games Total (Over/Under 2.5) resolves Over if 3+ maps are played, Under if fewer than 3 maps are played; maps won by forfeit/disqualification/walkover count toward total if match is completed; if match is canceled, ends in tie, or delayed beyond 7 days without winner, resolves 50-50.
  • Map Handicap (OLDBOYS- -1.5 vs Arch +1.5) resolves to OLDBOYS- if they win 2+ more maps than Arch; otherwise resolves to Arch; maps won by forfeit/disqualification/walkover count if match is completed.
  • Team name discrepancies (e.g., OLDBOYS- vs alternate spellings) are resolved by identifying the underlying real-world team; if no reasonable connection exists or ambiguity cannot be resolved, market resolves 50-50.

Edge cases & clarifications:

  • Match Forfeiture After Start: If match begins but is not completed and one team wins due to opponent forfeiture/disqualification/walkover: Match Winner resolves to the winning team; Games Total resolves 50-50; Map Handicap resolves 50-50; individual map winners resolve 50-50 unless that specific map was completed.
  • Clinching Map Forfeited: If the match ends due to the clinching map being forfeited, this counts as a completed match for Games Total and Map Handicap purposes; however, if that forfeited map is Map 1, 2, or 3 specifically, the individual map winner and round total markets for that map resolve 50-50.
  • Exact Round Total (21.5): If combined rounds on a map equal exactly 21.5, the Over/Under market for that map resolves 50-50.
  • Cancellation or Delay Beyond 7 Days: If match is canceled or delayed beyond 7 days from scheduled date (June 14, 2026) without a winner determined, all markets resolve 50-50.
  • Source Unavailability: If HLTV.org has not published final results within 2 hours after event conclusion, consensus of credible reporting and video evidence may be used as fallback source.
Timing: Resolution occurs upon match completion or upon determination that match will not be completed (cancellation, delay beyond 7 days, or forfeiture). HLTV.org is checked for final results; if unavailable within 2 hours of event conclusion, credible reporting and video evidence are consulted. Markets resolve no later than 2 hours after event conclusion or determination of non-completion.Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.

Polymarket

This market refers to the Counter-Strike Lower bracket quarterfinal 2 match between OLDBOYS- and Arch in the ESEA Advanced Europe Playoffs, initially scheduled for June 14 at 1:30PM ET. This market will resolve to "OLDBOYS-" if OLDBOYS- win the match against Arch. This market will resolve to "Arch" if Arch win the match against OLDBOYS-. If the match is canceled (not played at all), ends in a tie, or is delayed beyond 7 days from the scheduled date without a winner determined, this market will resolve to 50-50. If the match begins but is not completed, and one team wins due to the opponent's forfeiture, disqualification, or walkover, this market will resolve to the team who wins. If the match ends in a forfeit, disqualification, or walkover (team withdraws before the start and the other wins automatically), this market will resolve to 50-50. The resolution source for this market will be official information from https://hltv.org. However, if https://hltv.org has not published final results within 2 hours after the event’s conclusion, a consensus of credible reporting may be used instead including video evidence. In cases where a team’s listed name includes minor discrepancies from the resolution source, this market will resolve based on the underlying real-world match rather than exact name matching. Recognizable abbreviations, alternate or erroneous spellings, sponsor tags, affiliate or academy designations, regional identifiers, and minor formatting differences will be treated as referring to the same team, provided the intended team can be clearly and uniquely identified within the relevant competition. If a listed team name has no reasonable connection to any participating team, or if it matches or could reasonably refer to another team in the same competition such that the intended team cannot be unambiguously determined, this market will resolve 50-50.

Kalshi

If over 2.5 maps are played in the ESEA Advanced Europe 2026: Arch vs. OLDBOYS- CS2 match originally scheduled for Jun 14, 2026 at 1:30 PM EDT, then the market resolves to Yes.

Frequently asked questions

Prediction markets like those tracking this matchup operate differently from traditional sportsbooks. Rather than a bookmaker setting fixed lines, traders on these platforms directly buy and sell shares reflecting their belief in outcomes, creating dynamic odds that shift with new information. Sportsbooks typically offer tighter spreads but charge vig; prediction markets reward accurate forecasting but may have wider bid-ask spreads during low-volume periods. For esports events like this one, prediction market prices often reflect sharp, community-driven consensus that can diverge from sportsbook lines, especially as match time approaches and new roster or meta information emerges.

Polymarket and Kalshi may price this market differently due to distinct user bases, contract designs, and liquidity pools. Polymarket and Kalshi can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Polymarket focuses on binary map-count outcomes, attracting traders interested in series length, while Kalshi emphasizes individual map results, drawing those with granular tactical views. Differences in trading volume, fee structures, and the timing of information arrival across platforms can also create temporary price gaps. Arbitrageurs often exploit these spreads, but during low-activity windows, structural differences in how each platform frames outcomes can sustain modest divergence.

Several catalysts could shift odds before the match concludes. Roster changes, player substitutions, or last-minute lineup announcements for either team will likely trigger repricing, especially if key fraggers are unavailable. Recent map veto patterns, head-to-head records on specific maps, and meta shifts in the current CS:GO patch can also influence trader sentiment. Injury reports, team form leading up to playoffs, and community sentiment on social media may accelerate price movement. As match time nears, any official delay or format change would reset expectations, while early map results during the series itself will drive real-time volatility in map-winner contracts.
