توقع: US Open, Qualification WTA: Savannah Broadus vs Tyra Caterina Grant

Platform comparison

Market context

Savannah Broadus’s US Open qualifying meeting with Tyra Caterina Grant was a clear mismatch on paper even before play, with Grant ranked around No. 153 and Broadus around No. 304–307, and Grant named the stronger pre-match favourite by the market. There is no listed head-to-head before this tie, so traders had to rely mainly on ranking gap, recent level, and the fact that Broadus was entering a Grand Slam qualifying draw on a wild card, while Grant brought the more established tour record and a deeper junior-to-pro transition profile.[1][2][4]

The main historical read is that 0% yes reflected a market that was already treating Grant’s advance as near-certain, not a true zero-chance outcome. Similar qualifying spots tend to move only on late withdrawal, retirement, or a scheduling change, because the price is usually driven by who actually makes the court rather than long-run form alone; Grant’s US Open draw position and the published round-one listing signposted that the match was set, but not immune to a walkover or cancellation before start.[1][12] Broadus’s and Grant’s tournament result pages also show the match has already been completed, with Grant advancing 6-2, 6-4, which removes most live uncertainty unless a scoring or settlement dispute emerges.[8][13]

The catalysts to watch in markets like this are late injury notes, any pullback from the qualifying schedule, and official draw or score updates from the event itself. The US Open qualifying draw placed Broadus at No. 93 and Grant at No. 94 in the bracket, and contemporary match listings confirmed the scheduled start on Court 7, so any deviation from that setup would have been the key driver of a settlement flip rather than form news alone.[1][12]

FAQ

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
