LoL: Team Orange Gaming vs BIG (BO1) - Prime League 1st Division Regular Season

Platform comparison

Market context

The real-world event is a League of Legends match between Team Orange Gaming and BIG in the Prime League 1st Division Regular Season, scheduled for 9 July 2026 at 18:00 UTC. In prediction markets, a YES share pays out if the specified outcome occurs (here, Team Orange Gaming winning), while a NO share pays out if it does not. The current market implies a 0% chance of Team Orange Gaming winning, despite their recent 2–1 victory over BIG on 30 April 2026 and their stronger recent form (2 wins in last 5 matches) compared to BIG’s perfect 5-match streak [1].

Historically, BIG has dominated this matchup, winning six of seven prior encounters, including a 2–1 win in February 2025 [3]. This long-term record likely explains the market’s extreme skew, even though Strafe users predict a close contest with a 52.7% chance for BIG [1]. Traders should monitor official Prime League announcements for any format changes, as group stage matches are now Best of 3 (Bo3), which could alter dynamics compared to the Bo1 implied in some listings [7]. Additionally, watch for BIG’s squad updates or Team Orange Gaming’s roster stability, as both teams are German and operate within the same regional league structure [5]. Any delay beyond seven days or cancellation would resolve the market to a 50–50 split, per the terms.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
