Roland Garros, Qualification ATP: Emilio Nava vs Pedro Martinez

Platform comparison

Active sub-markets

Market context

Emilio Nava’s French Open qualifying match against Pedro Martinez has already been priced as a near-certainty in the market, with the crowd implying roughly a 100% chance of a Nava win. That is well beyond the kind of favourite status usually seen in Grand Slam qualifying, where the better-ranked player still tends to trade with some meaningful downside because clay can narrow the gap and best-of-three sets leaves room for swings. Here, the consensus is clearly with Nava, but the last layer of value is typically on the underdog side when a market becomes fully one-sided, especially in a surface-specific qualifier where hold percentages can be volatile.

The live tennis markets and bookmaker prices point in the same direction, with Sportsbet showing Nava around 1.36 and Martinez 2.87, and pre-match models from Tennis.com also leaning Nava, though not to the same extreme. That makes the main question less about who is favoured and more about whether the favourite price has become too compressed. Comparable qualifying matches at Roland Garros often move late on official order-of-play confirmation, injury news, or any sign of a physical issue from the shorter-priced player; if the match starts, the settlement outcome depends on who advances, but if it is not played or is pushed beyond the seven-day window, it can still resolve 50-50. The key trader watchpoint is whether the published schedule holds and whether either camp reports a withdrawal or medical concern before first serve.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.

On PolyGram, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in 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.
