Which mobs will eliminate Kai or Speed?

Platform comparison

Market context

Kai Cenat and IShowSpeed are set to run a hardcore Minecraft marathon on 7 August, with the market only paying out if a death message naming the relevant mob appears before the stream ends or is abandoned.[1] With the crowd already pricing **100% Yes**, the market is behaving like a near-certain event rather than a genuine binary debate, so programmatic traders will usually treat it as a confirmation check on stream continuity, not a probability-discovery trade.[1][3]

The useful frame is precedent: their previous Minecraft challenge generated extreme death counts and a long tail of failure modes, which is why mob-specific elimination markets on this event have quickly clustered at very high odds across multiple outcomes.[2][8] In practical terms, any bot, alerting stack, or conditional order logic needs to parse the on-stream death feed carefully, because the rules count only exact mob names and exclude lookalikes such as Wither Skeleton for Skeleton or Cave Spider for Spider.[1] That specificity matters when pricing edge cases in real time, since a qualifying death is enough to settle the market immediately.[1]

The main catalysts are operational rather than thematic: confirmation that the marathon actually starts, whether the duo continue the same world on the stated seed, and whether either player dies before the endurance run is concluded.[1] Polymarket’s own pop-culture listings show the broader event still has an active end-date risk, with related markets on whether the marathon finishes by late August already trading as high-probability outcomes.[4][12] For anyone automating a watchlist, the trigger set is simple: official stream start, any interruption or cancellation, and the first death screen that matches the market’s exact mob wording.[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.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Kalshi Fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi Fees trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
