Kai and Speed finish their Minecraft marathon by 2026?

Platform comparison

Market context

Polymarket has this contract at **7% YES**, so the market is pricing an early end to Kai Cenat’s Twitch marathon as a low-probability outcome even though the stream itself is already underway. Because settlement depends on the **Twitch broadcast stopping in ET and not resuming within 12 hours**, the on-chain position is not about whether they beat Minecraft eventually, but whether the broadcast actually ends before the deadline; positions are held as **conditional tokens** on **Polygon** and settled in **USDC**.

The closest reference point is the pair’s earlier Hardcore Minecraft run, which stretched for about **105 hours** and ended only after **42 resets** and a successful Ender Dragon kill, with coverage from Dexerto, Sportskeeda and TMZ all describing the marathon as an unusually long, stamina-heavy stream.[4][5][6] That history matters because it shows Kai and Speed have already accepted multi-day broadcasts, so a single-session finish is less important than whether fatigue, technical issues or a change of plan forces a real stream stop. On that reading, a 7% price implies traders think an interruption is still possible, but not the base case.[4][5][6][12]

For traders, the main catalysts are straightforward: official schedule changes, either streamer’s social posts, and any sign that the marathon’s structure has shifted from “keep going until done” to segmented sessions. A recent write-up noted the return marathon was announced for **7 August at 5pm ET**, with the duo streaming the same Minecraft world from separate channels, which means the decisive risk is not gameplay alone but whether Kai’s Twitch feed remains continuous enough to satisfy the contract’s 12-hour no-resume rule.[15] If the broadcast pauses, ends overnight, or moves off Twitch, that is far more relevant to settlement than whether the Ender Dragon, Wither, Elder Guardian or Warden gets finished first.[15]

UK Frequently Asked Questions

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.
