Market context
Young Washington, a historical epic about a young George Washington facing war and betrayal, is set to open domestically on its first weekend of July 3–5, 2026, with early tracking suggesting a box office gross between $23 million and $35 million. The market currently implies a 0% chance of the film exceeding its opening bracket, a stark contrast to Polymarket’s decimal odds format, which would display this as 0.00, whereas Kalshi and Betfair use implied probability and require KYC, limiting access for international traders. Fee structures also diverge: Polymarket charges no fees on trades, while Kalshi applies a 1% fee, and Betfair’s commission varies by volume, affecting net returns for high-frequency traders on this specific event.
Comparable historical epics released around Independence Day, such as *1776* (1976) and *The Patriot* (2000), opened between $20 million and $38 million, framing the current 0% probability as an outlier given the film’s $20 million budget and Angel Studios’ track record. Traders should monitor the finalisation of the 3-day box office figures on The Numbers, as studio estimates may shift before the official count on July 5. Recent coverage from Slate notes the film’s competition with *Minions & Monsters*, which could impact its domestic performance, and Box Office Mojo already reports $7.6 million in early domestic earnings, suggesting the final weekend may fall below the $23 million threshold if the trend continues.

Resolution & payout
Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.
Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.

- Which platform has the deepest liquidity?
- Polymarket — by a wide margin. Top markets reach $50-500M volume, Kalshi ~$200M cumulative, Betfair similar. Deeper liquidity means your trade moves the quote less.
- Is Betfair a Polymarket alternative?
