LoL: Bilibili Gaming vs T1 (BO5) - Mid-Season Invitational Playoffs

Platform comparison

Market context

The underlying event is the League of Legends Upper Bracket quarterfinal 1 match between Bilibili Gaming and T1 at the Mid-Season Invitational Playoffs, set for 4:00 AM ET on 4 July 2026. This contest resolves to Bilibili Gaming if they win, or to T1 if they prevail, with the current crowd-implied probability at 48% YES favouring Bilibili.

Historically, these teams have met eight times, with T1 winning five and Bilibili three, suggesting a slight edge for the Korean side that aligns with Strafe users predicting T1 at 74.2% [1]. In the 2025 MSI, T1 advanced to the Upper Bracket Finals while Bilibili dropped to the Lower Bracket, reinforcing T1’s tournament momentum [2]. Within this 2026 cycle, Bilibili holds an 8–12 record across 20 games, whereas T1 carries 12 wins, a disparity that contextualises the near-even 48% probability as a market underestimating T1’s form [3].

Traders should monitor pre-match roster announcements, any schedule shifts from the tournament organisers, and dependencies such as server stability or player availability. A recent tier list by Caedrel ranks T1 second and Bilibili sixth, a sentiment that may influence conditional order placements if the market drifts further from equilibrium [9]. Programmatically, this market would be approached by setting stop-loss triggers below 45% YES and using copy-trading bots to mirror high-confidence T1 positions, ensuring exposure aligns with the historical head-to-head data and current tournament records.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
