WTAPolymarket historical data and price history
WTA: a Polymarket sports series with markets recurring daily. Marketlens has captured 27,436 markets since June 19, 2026, of which 27,960 resolved, with $615.8M in traded volume. No new markets were collected from June 29, 2026 to July 6, 2026, or from July 24, 2026 to August 2, 2026, so windows inside those gaps return nothing. Order books are stored at full depth, with every individual price change captured at millisecond resolution on the most actively traded markets, alongside trades, candles, and the final resolution outcome.

Common questions
How many WTA markets are in the archive?
27,436 markets from June 19, 2026 through now, of which 27,960 have resolved and 26 are active. No new markets were collected from June 29, 2026 to July 6, 2026, or from July 24, 2026 to August 2, 2026, so windows inside those gaps return nothing.
What data exists for each WTA market?
Full depth L2 order book snapshots at regular intervals, individual trades, OHLC candles, and the resolution outcome, with the full price change stream at millisecond resolution on the most actively traded markets in the series. All of it is queryable by the series slug "wta" through the API and Python SDK, or downloadable as Parquet.
How much does a typical WTA market trade?
Average traded volume is $42.9K per market, $615.8M across the series.
Can I backtest strategies on WTA?
Yes. Pass the slug "wta" to client.backtest() in the Python SDK. Execution mode replays order books against real historical depth; Alpha mode, one bar per market, covers every market in the series and suits its longer horizons. This series mixes several bet types, so pass subtype= (e.g. "moneyline") to backtest one type at a time.
