National Bank Open: Raphael Collignon vs Alexei Popyrin

Platform comparison

Market context

The market for **Raphael Collignon vs Alexei Popyrin** is pricing Collignon at about **60% implied probability**, so the book has him a moderate favourite, with Popyrin the underdog and the main contrarian side if you think the grass-court pedigree matters more than recent form. Their only completed meeting came on grass at Halle in June, when Collignon beat Popyrin 6-4, 6-2, which gives the Belgian a live head-to-head edge in the exact surface this match is again likely to be played on.[2][6][16]

The broader form split is the key reason the market leans Collignon. Across the past 12 months, Collignon’s results have been stronger than Popyrin’s in the available datasets, and one source lists Collignon at 36-14 this season versus Popyrin at 10-19, while another shows Collignon winning 19 of 21 matches against non-top-100 opponents this year.[1][5] That supports the current consensus, but the value case for Popyrin is that his career level and upside remain higher, and he has historically been the more proven ATP-level player even if his 2026 record has been poor.[9][13]

The main catalysts are match timing and draw progression rather than any major injury narrative: the market settles if Collignon advances against Popyrin, but reverts to 50-50 if the match is not played or is materially delayed beyond the settlement window.[Market description] For traders, the practical watchpoints are whether the National Bank Open schedule holds, whether the pair is confirmed for the stated August 6 slot, and whether any late withdrawals or weather disruption change the path to a completed result. If the match is played on a quick hard court rather than grass, that would usually narrow the gap versus their Halle meeting, which is where the contrarian Popyrin angle has the most credibility.[2][16]
