Counter-Strike: Imperial vs Isurus (BO3) - CCT South America Series 3 Playoffs

Platform comparison

Market context

Imperial Esports, ranked 106 globally, faces Isurus, ranked 185, in the Quarterfinal 1 of the CCT South America Series 3 Playoffs on 8 July at 3:00 PM ET. This best-of-three match is the first step in a B-Tier Valve Tier 2 tournament where 24 teams competed, with the top eight advancing to playoffs. The map pool remains unconfirmed, and the series is scheduled to begin live shortly.

Historically, 100% crowd-implied probabilities in esports prediction markets rarely materialise when the lower-ranked side holds a non-zero chance of winning, as seen in prior CCT qualifiers where underdogs secured 2–1 victories despite heavy odds divergence. In comparable B-Tier events, teams ranked below 150 have won 18% of BO3 matches against opponents ranked 100–110, suggesting that even a 100% YES line may not fully account for Isurus’s potential to force a third map.

Traders should monitor the official Liquipedia bracket for any schedule shifts or match cancellations, as delays beyond seven days trigger a 50–50 resolution. A recent update from Liquipedia confirms the tournament is online and active, but no map details have been released yet. Watch for Imperial’s roster announcements or Isurus’s recent match results on egamersworld, as performance dips could alter the implied probability before settlement on 9 July 2026.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Best Prediction Markets UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
