Trade: Will Kylian Mbappe leave Real Madrid before August 31?
Resolution criteria on PolyGram: This market will resolve to "Yes" if Kylian Mbappé leaves Real Madrid at any point before August 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". This includes resignation, termination, joining another club (whether by permanent transfer or loan), or any other scenario in which he is no longer serving as a player of Real Madrid. A loan to another club constitutes leaving for the purposes of this market, even if Mbappé remains under contract with Real Madrid. If a departure is officially announced or agreed upon before August 31, 2026, 11:59 PM ET, this market will resolve to "Yes" regardless of when the move formally takes effect or is registered.

| Will Kylian Mbappe leave Real Madrid before August 31? | 14% YES | 86% NO |
Market context
Kylian Mbappé joined Real Madrid in summer 2024 on a five-year contract, making a departure before August 2026 a relatively near-term event. The current Polymarket order book implies a 14% probability of his exit within the next two years, reflecting market confidence in his tenure at the club. This low probability suggests traders assess the likelihood of termination, mutual agreement, or loan departure as minimal during this window.
Historical precedent offers limited direct comparison given Mbappé's status as one of football's highest-profile players. However, recent cases of high-value departures from Madrid—such as Cristiano Ronaldo's 2018 move to Juventus—typically involved explicit announcements well in advance rather than sudden exits. Mbappé's contractual terms and Madrid's financial commitment suggest any departure would require significant triggering events: sustained performance issues, managerial upheaval, or unforeseen personal circumstances. The market's 14% probability reflects these scenarios as unlikely but non-negligible.
Traders should monitor several catalysts through the settlement window. Managerial changes at Madrid, injury setbacks affecting Mbappé's playing time, or public statements regarding his future could shift sentiment materially. Real Madrid's competitive performance in La Liga and European competitions will influence both club and player satisfaction. Any official announcement of a loan arrangement or transfer agreement before 31 August 2026 would trigger resolution. Current reporting from outlets covering Madrid's squad planning will provide early signals of any potential departure discussions.

How active is this market?
$5K in lifetime turnover and $3K of resting liquidity puts this market in the below the median by volume for sports contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
Last 24 hours alone saw $1K in turnover, well above the lifetime daily-average for this market — a clear sign of news catalysing trader activity right now.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Key terms
- YES / NO share
- A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.
- CLOB
- Central limit order book. The matching engine that pairs YES buyers with NO buyers (effectively the same trade). Polymarket's CLOB on Polygon executes trades on-chain via the conditional-tokens framework.
- Liquidity
- USDC capital sitting in resting limit orders inside the order book. Deeper liquidity means smaller slippage on large trades and a tighter bid-ask spread.
- UMA optimistic oracle
- The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.
- Slippage
- The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.
- Conditional token
- ERC-1155 outcome share issued by Gnosis Conditional Tokens on Polygon. The token type that resolves to $1.00 or $0.00 at settlement.

Risk and regulatory note
Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
