LoL: Movistar KOI vs GIANTX (BO3) - LEC Regular Season

Platform comparison

Market context

Polymarket is pricing Movistar KOI at **66%** to beat GIANTX in this LEC regular-season best-of-three, with settlement paid in **USDC** on **Polygon** through the market’s conditional-token structure. In practical terms, that price means the contract is treating KOI as a clear favourite, but not a lock: a GIANTX series win would settle the market to the other side, while cancellation, a tie, or a delay beyond seven days without a result would push it to 50-50.

The market is sitting above the kind of mid-range probability that usually reflects a favourite with some matchup risk. Recent comparable previews have leaned towards KOI on the back of a stronger head-to-head record and steadier results, including analyses noting KOI’s advantage in longer series and GIANTX’s more inconsistent split form.[5][10] That said, GIANTX have shown they can win when the draft and early game break their way, and best-of-three formats can swing on one clean map or a single bad read in side selection.[1][7]

For traders, the main catalysts are straightforward: the official line-up and start confirmation, any change to the scheduled 17:15 UTC kick-off, and whether the series actually begins and finishes inside the market’s seven-day resolution window.[13][10] If there is a postponement, technical issue, or broadcasting delay, the on-chain contract mechanics matter more than the scoreboard narrative, because only a completed win for one side resolves cleanly; otherwise the market can fall back to 50-50 under its rules.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram 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.
