I make a very sizeable side income on prediction markets. Basically, through scraping, collecting, and cleaning an obscene amount of data.


I am aware of maybe 3 or 4 prediction markets. Can you provide some names?

Are you betting or cleaning data and reselling it or displaying it and earning income via ads?


I'm on Predictit, Poly, and Kalshi and use the data for betting.


Thanks! To contribute at least something to this thread, here are couple more prediction markets where you may or may not bet for real money:

- https://manifold.markets - https://www.unitarity.com/app - https://futuur.com - https://predict.hypermind.com/hypermind/app.html - https://www.metaculus.com - https://polymarket.com


Huh. I recently realized I might like cleaning and transforming data (and staring at the inputs and outputs and intermediary results of the pipeline to see the peculiarities of the data and what can be improved.) I didn't realize this was an activity that could make money, especially on its own.


What exactly is cleaning and transforming data?


Any chance you can share one example of a topic you've bet on and the data required to do so? Maybe one that is no longer relevant?


Cool project :-)
