Market context

Legacy are due to face GamerLegion in the IEM Atlanta 2026 semi-final, a best-of-three on 16 May, with the market currently pricing a 0% YES outcome for Legacy. In practical terms, that implies the crowd sees either a GamerLegion win or a settlement issue as far more likely than a straightforward Legacy victory. For context, both teams arrived at the playoffs from strong runs, with Legacy highlighted for a seven-match winning streak and wins over Natus Vincere, Astralis and M80, while GamerLegion have also posted notable results against Astralis and Liquid. Comparable high-stakes LAN semi-finals tend to be driven more by map veto quality and recent form than by long-run ranking, and the pre-match read from recent previews has been close to even, with some expecting a 2-1 series either way.

For traders, the key catalysts are the official ESL broadcast timing, whether the match starts within the settlement window, and any last-minute roster or schedule changes. Blast’s event listing and ESL’s own streams show the semi-final as a live scheduled match, while third-party previews have noted map preferences such as Mirage for Legacy and Nuke or Ancient for GamerLegion, which can matter if vetoes follow expectations. The market’s resolution also depends on completion: if the series is delayed, abandoned, or otherwise not decided in time, it can settle 50-50 rather than to either side. From an access and compliance angle, these markets may be subject to different treatment depending on jurisdiction: Germany’s GlüStV framework can restrict or complicate availability, US-facing users should note the reach of CFTC-style event-contract scrutiny, and “no-KYC up to $1,500” typically means smaller-volume participation without identity checks, but only where the platform and local rules allow it.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
