Which mobs will eliminate Kai or Speed?

Platform comparison

Market context

Polymarket is pricing this contract at **100% Yes**, so the market is treating a qualifying mob-related death message as effectively certain before settlement.[2][4] On Polymarket, that means traders buying Yes shares on Polygon with USDC-backed conditional tokens are already paying as if the relevant Minecraft death has either happened or is highly likely to be confirmed within the resolution window.[13]

That reading fits the broader pattern in Kai Cenat and IShowSpeed challenge markets: once a hardcore stream begins, deaths from common threats tend to be quickly reflected in the book, while rarer mobs can still sit at extreme prices if the challenge is live and the event has not yet resolved.[15][10] Comparable markets on the same event have shown very high probabilities for mobs such as Creeper and Skeleton, with some smaller-volume contracts on the event page reaching or holding near-maximum prices, which usually signals that traders expect at least one qualifying death message to appear before the marathon ends.[2][8]

For a trader, the main catalysts are the marathon itself, any schedule change, and whether the challenge is still live and unrestarted under the exact market rules.[1] The market settles only on in-game death messages that name the specified mob, so the key watch items are stream continuity, whether the duo abandon or pause the hardcore run, and whether any death is attributed in chat log wording to the mob named in the contract rather than a lookalike entity.[1]

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

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.
