Market context

Mirra Andreeva, the 17-year-old Russian talent, faces Jil Teichmann of Switzerland in the Roland Garros women's draw, originally scheduled for 31 May 2026 at 05:00 ET. Polymarket currently prices Andreeva's advancement at 90% (USDC on Polygon), reflecting her status as a rising junior prospect against a 27-year-old opponent ranked considerably lower. The conditional token structure means traders holding YES positions gain exposure to Andreeva's progression through this specific matchup, with settlement tied to whether she wins outright or advances via opponent retirement or disqualification.

Andreeva's trajectory provides the primary historical anchor here. She reached the Australian Open semi-finals in January 2024 at age 16, then claimed a WTA title in Hua Hin weeks later—making her one of the youngest players to achieve such milestones in recent seasons. Teichmann, meanwhile, has struggled with consistency and ranking volatility since returning from injury, with limited deep runs at majors in the past two years. This form disparity underpins the market's weighting, though Teichmann's experience on clay courts and familiarity with Roland Garros conditions warrant modest hedging against the 90% price.

Traders should monitor draw confirmation and any late withdrawals through late May, as Roland Garros scheduling occasionally shifts matches based on weather or court availability. Injury updates on either player—particularly Teichmann's fitness history—could trigger repricing. The settlement window extends to 7 June, allowing for rain delays typical of Paris in late spring, though the 50-50 tie-break only applies if the match remains unfinished beyond that date.

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.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does it cost to trade on Kalshi UK?

Zero. Kalshi UK routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
