Snapshot observed 2026-10-13T18:00:05.634Z. This analysis describes that snapshot and is not a live news update.

What the contract measures

The four provider events use different wording. The Kalshi winner contract resolves to Yes if the named player wins the 2026 Ballon d'Or [1]. The Polymarket winner contract resolves according to the winner of the 2026 Ballon d'Or, with France Football as the primary resolution source. If no winner is declared by December 31, 2026, 11:59 PM ET, it resolves to "Other" [2]. The Polymarket top 5 contract resolves Yes if the player finishes in the top 5 of the men's ranking, with ties resolved by France Football's official list [3]. The Polymarket top 10 contract uses the same structure for the top 10 and states that the ceremony is scheduled for October 26, 2026, in London [4]. That date appears in the rule text only.

Reading the snapshot

The observation time is 2026-10-13T18:00:05Z, and the retrieval time is 2026-10-13T19:30:59Z. The prices describe that snapshot only. Each event includes up to 12 markets, ordered by Yes price, so the included rows are the higher-priced listed outcomes.

In the winner events, Harry Kane's Yes price is 0.615 on Kalshi and 0.6265 on Polymarket. Lamine Yamal's is 0.315 and 0.2995. These are quoted snapshots, not executable quotes or verified probabilities. The platforms use different wording and close times, so the small gap does not show an arbitrage opportunity.

In the Polymarket top 5 event, the included Yes prices are 0.9855 for Kane, 0.973 for Yamal, and 0.91 for Mbappé. In the top 10 events, Kalshi shows 0.97 for Mbappé, 0.965 for Yamal, and 0.965 for Kane. Polymarket shows 0.995 for Yamal, 0.995 for Kane, and 0.987 for Mbappé. These are separate events, so their rankings should not be combined.

Listed close times differ. The Kalshi winner markets show 2027-12-31T15:00:00Z, while the Polymarket winner markets show 2027-01-01T04:59:00Z. The Kalshi top 10 markets show 2026-11-10T02:00:00Z, and the Polymarket top 10 markets show 2027-01-01T04:59:00Z. One Polymarket winner market, for Fabian Ruiz, lists 2026-10-31T00:00:00Z. The Kalshi winner excerpt says no end time was supplied, although its market records list one.

What remains uncertain

Each event is a partial sample: 12 of 17 Kalshi winner markets, 12 of 19 Polymarket winner markets, 12 of 19 Polymarket top 5 markets, 12 of 30 Polymarket top 10 markets, and 12 of 30 Kalshi top 10 markets. Omitted players should not be read as priced lower. The evidence does not include volume, trader counts, liquidity, or explanations for price changes. It also contains no news on the ceremony or results, so the stated ceremony date is taken only from the contract rule text.
