Highest grossing movie in 2026?

Platform comparison

Market context

The highest domestic earner in 2026 looks like a straight contest between a few franchise releases, with **Spider-Man: Brand New Day** currently the favourite in trader pricing and **Avengers: Doomsday** the main late-year spoiler. Polymarket’s event page puts Spider-Man well ahead on consensus, and coverage from Action Network and Covers has echoed that split, with Spider-Man leading and Avengers, Toy Story 5 and the new Mario film trailing at longer prices.[15][17][3] The current crowd-implied probability in this market is **0% YES**, which is far below the broader market consensus and suggests either no active pricing here or a stale quote rather than a genuine view on the race.[15][17]

Historically, markets like this tend to reward two things: an early summer launch with broad four-quadrant appeal, or a December juggernaut that overperforms quickly enough before the calendar closes. That framing favours Spider-Man on release timing and franchise reach, while giving Avengers a narrower path because a 18 December debut leaves only a short window for 2026 grosses to accumulate before settlement.[15][7] The main value angle, if any, is contrarian support for a film with the cleanest path to long legs rather than simply the biggest brand name, since opening-weekend hype can be misleading when the market is settled on calendar-year domestic gross.[15]

Traders should watch release-date changes, trailer response, and any sign of summer crowding or holiday congestion, because those factors will drive opening-weekend size and the speed of box office decay. Current write-ups point to Spider-Man’s July slot, Toy Story 5’s June positioning, and Avengers’ late-December berth as the key structural differences, while the Super Mario sequel remains a live outsider if family audiences again turn out at scale.[15][3][18] Any shift in Disney or Sony schedules, or a stronger-than-expected marketing cycle for one title, would matter more here than awards buzz or critic sentiment.[15]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Who Will Win, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

UK Frequently Asked Questions

Where can I trade this market with the lowest fees?

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%.
