Which mobs will eliminate Kai or Speed?

Platform comparison

Market context

Kai Cenat and IShowSpeed are doing a hardcore Minecraft marathon in which they must survive long enough to clear bosses on the same Java Edition world, so any mob-specific elimination market is really a live test of whether the run lasts long enough for one of those deaths to happen. The crowd price at 100% YES is already close to treating a mob death as inevitable, which is easier to read on Polymarket as an implied probability than on Betfair or Smarkets, where the same view would usually be translated into decimal odds and then reduced by commission or fees.

The best comparison is their previous hardcore Minecraft run, which ultimately ended only after five days, more than 105 hours, and 42 deaths, and TMZ reported at the time that the duo were already getting heated over failed attempts at the Ender Dragon[5][14]. That history matters because the current market covers not just a single boss fight but an extended marathon against multiple high-risk mobs, including the Warden and Elder Guardian, both of which tend to punish mistakes far more sharply than standard survival play. In platform terms, Kalshi’s event contracts are typically simpler to read on a 0–100 scale, while Betfair and Smarkets can show a different effective price once the exchange commission and liquidity spread are included.

For traders, the main catalysts are the actual stream start, whether both creators stay on the same schedule, and whether they decide to continue across multiple sessions rather than abandon the run early; reporting ahead of the launch said the marathon was set for 5 pm ET on 7 August and could run for months[2][6]. Any platform-specific friction also matters here: Polymarket and similar crypto-native books generally offer broader access but different settlement mechanics, while regulated venues such as Kalshi, Betfair, and Smarkets can involve tighter KYC and regional access limits, which affects who can trade the same view at the same moment.

Methodology

This page compares Which mobs will eliminate Kai or Speed? specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets. The live probability is the Polymarket mid; the comparison columns summarise each venue's fee structure, KYC, settlement currency and payment rails. Every CTA routes to Robinhood Prediction Markets, which mirrors the Polymarket order book at 0% fees.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
