LoL: ROSSMANN Centaurs vs BIG (BO3) - Prime League 1st Division Group A

Platform comparison

Market context

Polymarket is pricing this ROSSMANN Centaurs–BIG contract at **0% YES**, so the market is currently treating a Centaurs win as effectively out of the money on-chain. On Polymarket, buyers post **USDC** against **conditional tokens** on Polygon, and the eventual resolution follows the match result rather than the live scoreline alone; if the fixture is not played, ends tied, or drifts beyond the settlement window without a winner, the market can resolve 50-50 under the contract rules.

That near-zero price is consistent with the recent head-to-head picture. BIG have already beaten ROSSMANN Centaurs in Prime League play this year, including a 2–0 result recorded in summer regular-season data, and Liquipedia’s 2026 Summer page also shows BIG ahead in the same competition context.[14] More broadly, historical listings on Polymarket have described BIG as the stronger side in this pairing, while ROSSMANN Centaurs have been positioned as the underdog in prior markets and tournament pages.[6][11]

For traders, the key catalysts are simple: official start confirmation, roster line-ups, and whether the series actually begins on schedule at the Prime League’s listed time.[2][5] If the match is delayed, interrupted, or rescheduled, the contract’s 7-day rule matters more than in-play score movement, because settlement can shift to 50-50 if no winner is determined in time. Independent match trackers currently list the BO3 for 6 August, which is the main thing to watch against any late schedule change.[2][3]
