National Bank Open: Nikola Bartunkova vs Amanda Anisimova

Platform comparison

Market context

Amanda Anisimova’s match with Nikola Bartunkova at the National Bank Open has been priced as a clear but not overwhelming favourite for Anisimova, with the crowd-implied probability at 47% YES, suggesting the market is treating the contest as competitive rather than one-way. Independent tennis data also points the same way: String Tension’s Elo model gives Anisimova a 73.2% win chance, while Flashscore and Sofascore list her as the higher-ranked player in the matchup.[2][4][6]

The main historical frame is that there is no head-to-head record to anchor expectations, so traders are leaning on ranking, recent form and surface fit instead of direct precedent.[1][2][13] On hard courts, Anisimova’s season profile is stronger overall, but Bartunkova has already shown she can trouble seeded opposition in Toronto, which is the sort of upset that keeps the price from getting closer to certainty.[1][14]

The key catalyst is whether the scheduled Toronto meeting actually goes ahead and reaches a result, because the settlement rules revert to 50-50 if the match is not played, or is delayed beyond seven days without a winner. The near-term watchlist is the official order of play, any weather or scheduling disruption, and whether either player withdraws before first ball, since all three can turn a seemingly straightforward favourite into a tie outcome for the market.[3][7]

UK Frequently Asked Questions

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
