LoL: Once Upon A Team vs ZennIT (BO3) - Road Of Legends Regular Season

Platform comparison

Market context

Once Upon A Team v ZennIT in Road Of Legends is priced at **100% YES** on Polymarket, which means the contract is effectively treating a Once Upon A Team win as a certainty and a ZennIT win as zero. On Polymarket, that price sits on-chain as USDC-backed conditional tokens on Polygon, so the market will pay out according to the match result or the stated fallback rules if the fixture is not completed as scheduled.[15]

That extreme reading is not consistent with the broader results history between the sides. Recent and archived match pages show mixed outcomes: ZennIT beat Once Upon A Team 2-0 in April 2025, while Once Upon A Team won the most recent reported BO3 on 14 May 2026 by 2-1.[6][2] Head-to-head summaries also point to a generally competitive pairing rather than a one-sided edge, with ZennIT leading the all-time series on some databases, while others list Once Upon A Team with a narrower recent advantage.[8][9][11]

For traders, the practical catalysts are confirmation of the series actually being played, the official start time, and any late schedule changes from Road Of Legends organisers or team channels. The fixture was listed for 4 August 2026, but at least one results page already records a completed BO3 on that date with ZennIT winning 2-1, which is the key fact pattern for settlement unless the market’s contract terms or event listing indicate a cancellation, delay beyond the seven-day window, or another resolution path.[4][7][15]
