National Bank Open: Lanlana Tararudee vs Amanda Anisimova

Platform comparison

Market context

Polymarket is pricing this contract at **50% YES** on USDC-settled conditional tokens on Polygon, which leaves the market essentially balanced between Lanlana Tararudee and Amanda Anisimova advancing. With the settlement window running to 12 August, the trade is mainly about whether the scheduled Toronto second-round match is completed with a winner, or whether it falls into one of the contract’s non-standard outcomes and is forced to 50-50.

The baseline read is that Anisimova has been treated as the stronger player by other tennis markets and previews, but Tararudee has already shown she can extend matches on this court by coming through a tight opener against Emerson Jones in three sets, 7-6(2), 6-2. The National Bank Open’s official preview also places Anisimova as the evening feature against the Thai qualifier, while recent previews frame the American as the firmer favourite because of pedigree and hard-court level. Comparable WTA second-round markets often sit well away from even money when a seeded or top-ranked player faces a qualifier, so a 50% price here suggests either respect for Tararudee’s current run or a market waiting on final line-up and live confirmation rather than a strong directional view.

For traders, the main catalysts are the match status on the tournament schedule, any late court-order changes, and whether the contest is actually begun and finished before the resolution cut-off. Sportsnet listed Tararudee vs Anisimova in Toronto’s Tuesday evening slot, while live tennis listings showed the match starting around 00:10 UTC on 5 August, so timing and any weather or schedule shifts matter for a market that resolves differently if the match is cancelled, tied, or delayed beyond seven days. Anisimova’s recent return to hard courts after an injury-hit spell has also been flagged in preview coverage, so any pre-match withdrawals or medical issues would be more relevant to the contract than the broader tournament context.
