Market context
The real-world event is the domestic opening weekend gross of the historical epic *Young Washington*, which premiered on 3 July 2026 and is currently competing against *Minions & Monsters* during the Fourth of July holiday. Early tracking indicated a potential opening between $23M and $35M, with some analysts projecting a total domestic run reaching $145M, yet the current crowd-implied probability of 0% suggests the market expects the film to fall below the lowest bracket or face significant data discrepancies [1][3].
Historically, historical epics released during major holidays often see inflated opening numbers due to patriotic sentiment, yet they frequently suffer sharp second-week drops if the narrative lacks broad appeal, as seen with similar biopics in recent years [5]. The 0% probability is unusual given the $20M budget and the film’s strong early reviews, which some viewers likened to *Braveheart*, suggesting the market may be mispricing the film’s resilience or waiting for final non-estimate figures before resolving [6].
Traders should monitor the finalisation of the 3-day box office figures on The Numbers website, specifically the shift from studio estimates to confirmed data between 3–5 July, as this is the settlement trigger [4]. Recent coverage highlights the intense competition with *Minions & Monsters*, which has a studio tracking of $95M for its 5-day run, potentially overshadowing *Young Washington*’s performance and affecting its final gross [7]. The settlement window ends on 6 July 2026, so any delay in final data release could impact the market’s resolution timing.
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.
FAQ
- 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.
- What's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
- What does Polymarket cost to trade?
- Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.
- How fast are USDC deposits?
- Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi Fees trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
