Estoril Open: Pedro Martinez vs Luciano Darderi

Platform comparison

Market context

Polymarket’s contract on Pedro Martinez v Luciano Darderi is trading at **0% YES** right now, which means the market is pricing almost no chance that Martinez advances and, by implication, is effectively treating Darderi as the side most likely to progress. On Polymarket, buyers use USDC on Polygon and the contract is settled through conditional tokens, so the quote reflects the market’s view of who will advance, not just who is favoured on paper.[8]

That near-zero price sits well below the wider tennis market consensus, where pre-match previews and odds for this Estoril clay-court meeting have generally made Darderi a solid favourite. Recent predictions put Darderi around the high-70s in win probability, with Martinez closer to the low-20s, and some previews have even suggested a straight-sets win for Darderi.[1][2][3][5][6][9] In practice, a 0% YES reading can happen when traders think the outcome is close to locked in, or when liquidity is thin and the order book has been pushed hard to one side.

For a Polymarket user, the main catalysts are whether the match is actually played, whether either player withdraws before first ball, and whether the result is officially completed inside the market’s settlement window. The market rules say a walkover, cancellation, tie, or a delay beyond seven days without a winner would settle 50-50, while an in-play retirement can still be settled on the player who advances.[8] The live score feeds around this event show the match listed as in progress, so any stoppage, retirement, or schedule change would be the key thing to watch rather than pre-event speculation.[10]
