Market context

Alejandro Tabilo of Chile faces Kamil Majchrzak of Poland in a Roland Garros ATP match scheduled for 24 May 2026. The Chilean, ranked in the top 20, brings consistent clay-court form and recent Grand Slam experience. Majchrzak, a Polish player with a volatile ranking history, has shown occasional flashes on clay but remains less predictable at the highest level. The 100% implied probability reflects Tabilo's superior seeding and recent trajectory, though such extreme odds in tennis are unusual given the inherent volatility of individual matches.

Historical precedent suggests that when a lower-ranked or less-favoured player faces a seeded opponent at Roland Garros, markets often price in the favourite too heavily early. Upsets at clay majors occur regularly—approximately 15–20% of matches involving a clear ranking gap produce the lower-ranked player's victory. The current settlement window extends to 31 May 2026, allowing seven days beyond the scheduled date for completion, which aligns with standard tournament scheduling but provides little buffer for weather delays common in Paris in late May.

Traders should monitor official Roland Garros draw confirmations and any injury announcements affecting either player in the weeks preceding the match. Recent ATP rankings, head-to-head records, and surface-specific form will shift market perception closer to the event. Under German GlüStV regulations, this market remains accessible to EU traders; US CFTC reach applies to US-domiciled participants. The no-KYC threshold of $1,500 USD per trade applies to this specific market, meaning positions below that value avoid enhanced identity verification on compliant platforms.

Methodology

We track Roland Garros ATP: Alejandro Tabilo vs Kamil Majchrzak on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
