Highest grossing movie in 2026?

Platform comparison

Market context

Polymarket currently has **Spider-Man: Brand New Day** as the market leader, with traders assigning it the strongest consensus for the 2026 domestic gross race, ahead of **Avengers: Doomsday** and **Toy Story 5**.[14] On Polymarket, positions are held as USDC on Polygon and settle through conditional tokens, so the contract is a direct price on which title finishes top of the **Gross** column for 2026 domestic calendar receipts, not on worldwide totals or lifetime box office.[14]

That 0% crowd price on the long tail does not mean the field is locked; it usually reflects thin liquidity, stale pricing, or traders waiting for more schedule certainty rather than a view that the outcome is impossible. Comparable box office forecasts still cluster around the same handful of franchises: Spider-Man, Avengers, Pixar, and Nintendo-led family IP dominate public prediction lists, while some models have even put **The Super Mario Galaxy Movie** or **Avengers: Doomsday** first, showing that the top spot is still contested across analysts and enthusiasts.[1][11][19] In practice, these markets can move sharply once one title’s release date, trailer response, or pre-sale pace looks materially stronger than the others.

The main catalysts are release timing and whether the big four keep their current windows: **Spider-Man: Brand New Day** is framed as a late-July play, **Toy Story 5** as a June family release, **The Super Mario Galaxy Movie** as a major animated contender, and **Avengers: Doomsday** as a late-year event picture.[14] Traders should also watch for schedule shifts, casting or trailer drops, and whether competing sequels are delayed into 2027, because the market resolves strictly on 2026 domestic grosses and the final winner is taken from Box Office Mojo’s calendar-year gross table.[14]

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 PolyGram, which mirrors the Polymarket order book directly.

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.

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%.
