What It Is

BetData is a personal project by Michael Dent, founded in 2016. It is positioned as a website providing “real-time and historical political betting odds for academic and research purposes.” It is not a marketing/SEO platform in the traditional sense, but rather a data archival service centered on political betting markets, prediction markets, and changes in the perceived probability of political events.

Core Capabilities

According to the site description, BetData independently tracks political betting odds offered by individuals on the Betfair Exchange and stores historical data. The website states that it has tracked 137 markets, with 9 markets currently active. Its collection method involves capturing and storing the average back and lay prices publicly published by Betfair, as well as volume information, approximately once per minute. For researchers, the value of this type of data lies in the fact that betting prices can be viewed as crowd-based probability judgments backed by real money at a given point in time, making them suitable for studying prediction markets, political forecasting, and shifts in expectations around major events.

Pricing and Access

The scraped text does not disclose a pricing model, paid plans, free trial, API, or bulk export capabilities. The site includes a login entry point and a Contact page, but no more specific information about subscriptions, payments, or enterprise services was found. As a result, its commercial usability and data access limitations require further confirmation. Access availability from mainland China is not provided in the text and is therefore unknown.

Pros and Cons

The advantages are that the data topic is highly focused, the time span runs from 2016 to the present, and the collection frequency reaches once per minute. Its data source, Betfair, is described as a betting exchange with high global trading volume and liquidity, making it suitable for long-term historical time-series analysis. The drawbacks are also clear: the data source is relatively singular, and the project states that it has no official relationship with Betfair; the website does not present comprehensive information about data interfaces, permissions, support, or service levels; and it has only a weak connection to the marketing/SEO category, meaning it cannot be used for keyword research, rank tracking, or ad campaign optimization.

Who It’s For

It is better suited to academic researchers, political data analysts, prediction market research teams, and anyone interested in studying how odds reflect changing expectations around public events. It is not suitable as a marketing growth, SEO monitoring, or enterprise-grade market intelligence platform.
