Kai and Speed finish their Minecraft marathon by 2026?

Platform comparison

Market context

Kai Cenat and IShowSpeed have launched a hardcore Minecraft marathon that is built to run far longer than a normal stream, because the finish now appears to be defeating multiple bosses rather than simply clearing the Ender Dragon. Coverage ahead of launch said the stream would go live on 7 August at 5 p.m. ET, and one report noted that the earlier 2024 run took more than 105 hours across 42 restarts before the duo finally beat Hardcore Minecraft.[15][12][2]

That history is the key comparison for reading the current **6%** crowd-implied probability. The last marathon showed that these events can last several days even when the objective is narrower, which supports a low short-dated chance of an early end; however, the current setup may be even less likely to finish quickly if the remaining checklist really includes the Ender Dragon, Wither, Elder Guardian and Warden. For a cross-platform read, that leaves the prediction market pessimistic on an early stop, while any sportsbook-style line would likely need to be equally heavily shaded towards the stream continuing rather than ending soon, given the duration risk embedded in the format.[16][12][15]

Traders should watch for three catalysts: whether Kai or Speed announces a planned pause, whether the pair shift from continuous gameplay to an edited or split-session format, and whether either streamer encounters platform, travel or technical interruptions that could force a break. Because settlement depends on Kai’s Twitch broadcast ending and not resuming within 12 hours, a temporary offline period would not automatically satisfy the contract. The latest pre-run reporting also suggested no fixed end time had been published, which keeps schedule risk high and makes any progress update or boss-count milestone more important than ordinary viewer metrics.[16][15]

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

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.
