World Cup Final: U.S. Viewership

Platform comparison

Market context

Polymarket has this contract pricing **0% YES** while the actual event has already happened, so the market is effectively saying there is no remaining path to a non-zero settlement under the current bracket structure. On Polymarket, traders post and match risk in **USDC** on **Polygon**, with the outcome represented by **conditional tokens** that settle against Nielsen’s first official U.S. viewership estimate for the World Cup final between Spain and Argentina.[4][5]

For context, the available comparables point to an exceptionally large audience, not a marginal one. Nielsen-linked reporting put the English-language Fox audience at **38.937 million** and the combined Fox/Telemundo/Peacock total at **62.837 million**, which would sit at the very top of any realistic bracket ladder for a U.S. viewership market.[4][5] That makes the current zero price understandable only as a reflection of the market having already locked in around the eventual reporting regime, rather than a live read on the broadcast’s scale.

A trader watching the contract now should focus on the **first official Nielsen release**, because the rules say later revisions do not matter and the market resolves from that initial figure alone.[4][5] The main dependencies are whether Nielsen’s reported average total viewers matches the combined national audience that broadcasters have already publicised, and whether any technicality around brackets places the number just above or below a cut-off; if it lands exactly between two brackets, the higher range wins.[4][5]

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
