US Open, Qualification WTA: Priscilla Hon vs Joanna Garland

Platform comparison

Market context

Priscilla Hon and Joanna Garland met in US Open qualifying after both came through the opening round, with Hon beating Alice Tubello and Garland edging Leyre Romero Gormaz. The market’s 0% yes price points to a settled view that the match has effectively already been decided or is otherwise no longer tradable, rather than a live split on pre-match strength; the pair were listed roughly level on some pre-match boards, with Garland only a slight favourite in one live market, which makes the zero price stand out sharply.

Historically, qualifying matches at Flushing Meadows are most sensitive to fitness, scheduling and whether a player has already spent three sets on court in the first round. Here, Hon had the longer opener, while Garland’s win over a seeded opponent was the more eye-catching result, so any reading from form alone would have leaned on recent match load as much as ranking. The official US Open schedule placed the women’s qualifying rounds on 24–27 August, leaving little room for delay before the main-draw cutoff.

For traders, the key catalyst is whether the second-round result is officially recorded and whether there is any disruption to the qualifying schedule before the 2 September settlement window closes. The live match listing showed the fixture as completed, and the US Open’s own schedule confirms qualifying is concentrated in a four-day block, so a late cancellation or uncompleted match would be the main route back to a 50-50 outcome.

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.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Trump Prediction route into the same order book at 0% fees.

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.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

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.
