Market context
A film titled "The End of Oak Street" is scheduled for theatrical release on 14 August 2026, with the opening weekend box office performance (14–16 August) forming the basis of this market's resolution. The current crowd-implied probability of 0% suggests traders are pricing in either a cancelled release, a direct-to-streaming pivot, or confidence that the film will underperform all specified brackets. This extreme positioning warrants scrutiny against comparable independent and mid-budget releases, particularly those targeting niche audiences or releasing during summer's tail end when major studio tentpoles dominate screens.
Historical precedent shows that August releases outside the first two weeks face structural headwinds. Films released in mid-to-late August typically gross between $5–15 million domestically over opening weekends unless they carry significant franchise recognition or star power. The absence of major marketing announcements, trailer releases, or trade coverage as of early 2026 suggests limited studio backing or a genuinely troubled production. However, a 0% probability implies certainty of failure—a rare market state that often reflects incomplete information rather than genuine consensus.
Traders should monitor whether production updates, release-date confirmations, or marketing campaigns materialise in the months preceding August. Any announcement of a theatrical release alongside distribution commitments would immediately challenge the current pricing. Conversely, silence or a quiet streaming announcement would validate the bearish positioning. The resolution mechanism's reliance on The Numbers' final figures rather than studio estimates means early tracking data will be crucial for assessing whether the film reaches any threshold bracket.
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
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 Who Will Win. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.
- 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.
- 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%.
