We intend to soon offer on a trial basis certain historical market data free of charge as part of an initiative to improve the accessibility, transparency, and validation of prediction markets.
We hope in the near future that by making certain historical market data freely available (and foregoing a revenue stream) we will encourage further academic and business study and support of the prediction market phenomenon.
We will present data by category, event, market group, and individual market. No personal data will be made available. The initial reports that we will provide are closing prices and time and sales of each trade on a market. The data sets will be in a CSV format and will be refreshed daily.
We are looking for a limited number of people to Beta test our application and market data sets. Please contact us on firstname.lastname@example.org if you are interested in being a tester and getting access (T&C's will apply) to historical market data.
