WTA Exact Match Score — did the favourite win?
The side the opening price favoured finished in the money 60 % of the time across 140 settled WTA Exact Match Score contracts that opened away from 50 ¢ among the day's most traded contracts, 2026-08-23 – 2026-09-12. Contracts opening at 20–30 ¢ — 35 of them — closed Yes 56 % of the time.
| Opening price | Contracts | Closed Yes | Closed No | Yes share | Open at last print |
|---|---|---|---|---|---|
| 10–20 ¢ | 20 | 5 | 9 | 36 % | 6 |
| 20–30 ¢ | 35 | 18 | 14 | 56 % | 3 |
| 50–60 ¢ | 29 | 16 | 9 | 64 % | 4 |
| 60–70 ¢ | 22 | 14 | 2 | 88 % | 6 |
| 70–80 ¢ | 20 | 17 | 2 | 89 % | 1 |
| other opening prices | 43 | 25 | 13 | 66 % | 5 |
| Total | 169 | 95 | 49 | 66 % | 25 |
Opening price = the contract's first recorded print on the first day it ranked among the day's ten most traded contracts of the series (not its listing price), grouped in 10 ¢ steps (contracts quote 0..1 = 100 ¢). Outcome implied by its last recorded print across the window (≥ 0.97 = Yes, ≤ 0.03 = No; the rest still open at the last print) — venues publish the official result, we record the market. The sample is the daily top-10 by turnover, so it leans towards the closest, most traded contests. Deciles with fewer than 20 contracts are folded into one row.

WTA on Kalshi — market types across the series
Across 10 WTA series on Kalshi, 26,459 contracts have been listed as of 2026-11-03: moneyline / winner 21,490 · total / over-under 2,768 · other 2,201. Counted from every contract file of the family, not from the traded top-10.
| Market type | Contracts listed (all time) | Listed last 30 days | Share |

| total / over-under | 2,768 | 821 | 10 % |

Kalshi WTA series— market type read from each contract's venue identifier (ticker suffix on Kalshi, slug suffix on Polymarket, market description on predict.fun and OG.com), counted over every contract listed in the family as of 2026-11-03; “listed last 30 days” counts contracts whose venue settlement time falls in that window. Every one of them is in the day bundle of its day.
How a WTA Exact Match Score contract trades
On Kalshi, a WTA Exact Match Score contract trades for about 43 h from open to close, is listed roughly 10 min before it opens, and quotes in 1 ¢ price steps (0..1). Measured on the 4 contracts captured on 2026-09-12.
Build a WTA Exact Match Score model on this data
Every settled WTA Exact Match Score contract is a labelled example: the winner, the line or the total that cleared is the label, and the day bundle holds each contract's full order-book path and trade tape, nanosecond-stamped, from the first quote days before the event to the last print — the features for that label. The statistics on this page cover the most traded contracts per day; the bundle holds every contract listed on Kalshi that day.
Split by season and match day, never at random — the contracts of one slate share injuries, weather and the same public money, and a random split leaks the slate's results into training; walk forward over game days and purge the days whose contracts were still open. The sports-model guide works the closing-line benchmark, the pre-game line path and that split through.
Purchased data is for your own use — backtesting, research, analytics and training your own models, in-house or in your own products; the trained models and derived data you build from it are yours. The raw files and tick streams themselves may not be redistributed, resold or published. The full terms are on the data license page.
Why buy Kalshi WTA Exact Match Score data here
Four things every page on this site is built on — and the reason the numbers above exist at all.
We record everything
The complete public feed of each venue as it was published: every Level-2 snapshot and update at the venue's full book depth, every trade with its aggressor side, every quote, funding, mark-price and liquidation event — for every instrument the venue lists, every UTC day since we added the venue. Nothing sampled, no top-N cut, no on-demand capture.
Institutional grade
Captured co-located at the venue with the exchange timestamp and our receive timestamp in integer nanoseconds, an event-id chain that makes any gap visible, and one normalized schema across 35+ venues — the same capture our own high-frequency trading engine and enterprise feeds run on.
€1 per instrument-day
Any instrument-day is €1, series-day bundles start at €1 — no subscription, no minimum order, no tiers to unlock. Credit packs lower the effective price and never expire, and every venue has free full-day samples to test against first.
Self-service for everyone
Pick the days in the Data Shop, pay by card as a guest and download immediately — no sales call, no enterprise contract, no KYC. Coding agents buy the same files through the MCP server, and the free Agent Skill teaches them the format.

Kalshi WTA Exact Match Score data — FAQ
What Kalshi WTA Exact Match Score data can I download?
Tick-by-tick trades and Level-2 order-book depth for every contract of the WTA Exact Match Score series on Kalshi (4 contract files on the latest day). One bundle = one UTC day of the whole series.
What is the Kalshi series ticker for WTA Exact Match Score?
KXWTAEXACTMATCH — every contract of the series carries this prefix in its ticker (followed by the event date and strike). Files in a day bundle are named by the full contract ticker, so a bundle holds every KXWTAEXACTMATCH-* contract listed that UTC day.
How far back does the WTA Exact Match Score data go?
Coverage runs June 2026 – September 2026 — 26 trading days in total.
What format are the Kalshi files in?
One zstd-compressed text file per contract per UTC day, in the same normalized schema as our crypto venues — see the market-data specification; free samples on the downloads page.
Can I get Kalshi WTA Exact Match Score data as CSV or Parquet?
Yes — trades export as gzipped CSV or Parquet at no extra cost, with integer microsecond UTC timestamps that load straight into pandas, polars or DuckDB. Kalshi records full order-book depth without a separate BBO stream, so book data ships in the native tick file — the free reader script converts it locally. See the formats overview.
How much does Kalshi WTA Exact Match Score historical data cost?
€1 per series-day bundle — every contract of the series for that day — no subscription, no minimum order; buy as a guest in the Data Shop and download immediately. Credit packs lower the effective price and never expire.
Do I need an account or a sales call?
No. Pick the WTA Exact Match Score series-days in the Data Shop, pay by card as a guest and download immediately — no subscription, no minimum order, no KYC, no enterprise contract, no sales call. Coding agents buy the same bundles through the MCP server.
How is the Kalshi WTA Exact Match Score data captured?
Co-located at the venue, message by message: every Level-2 update and every trade print carries the exchange timestamp and our receive timestamp in integer nanoseconds, an event-id chain makes any gap visible, and one normalized schema across 35+ venues means a parser written for Binance reads these files unchanged. It is the same capture our own high-frequency trading engine runs on — nothing sampled, no top-N cut.
