Market context
MrBeast’s next long-form upload will decide whether the first seven-day view count lands in the lowest bracket or somewhere higher, and the current 0% YES pricing implies traders see the named range as effectively unreachable. For a programmatic approach, the key task is to monitor the upload timestamp on the official channel and then sample the public YouTube views counter at a consistent interval, because the market resolves on the seven-day total rather than any day-one spike.[2][3]
The closest comparable read-through is MrBeast’s recent run of very large launches: Polymarket’s own live dashboard shows the week-one market clustered around 60–70M and 50–60M, while another MrBeast week-one contract previously resolved at 80–90M after the referenced video reached 80.9M views by day seven.[2][3] That combination suggests the market is usually driven by a narrow band of upload performance rather than a binary hit-or-miss outcome, which matters if you are building alerts, bot triggers, or conditional orders around bracket migration instead of outright direction.[3][11][12]
The main catalysts are simple but timing-sensitive: the next upload date, whether it is a normal video rather than a Shorts-style post, and how quickly the first 24–48 hours convert into momentum. MrBeast’s channel remains the authoritative resolution source, so an automated workflow should watch for a new upload, store the public timestamp, and then compare the live views counter at the seven-day mark against the bracket rules, including the clause that no upload by 31 August 2026 forces the lowest range.[1][2][3]
Methodology
We track # of views of MrBeast video week 1? across the five venues with material prediction-market liquidity. The probability shown is the live Polymarket mid; the comparison rows summarise how each venue treats the underlying contract — fees, KYC thresholds, settlement currency, deposit options. The highlighted row marks the cheapest route into Polymarket's order book.
Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
UK Frequently Asked Questions
- 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 Polymarket Review UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.
- 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. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.
- 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.
- How do I deposit on Polymarket from the UK?
- UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
