Just under a month ago, I said “web app idea: one where you can set up a play-money prediction market with only a few clicks”, because I was playing around on Hypermind and wishing that I could do my own Hypermind. It then occurred to me that I can make web apps, so after getting up to date on modern web frameworks I embarked in creating such a site.
Anyway, it’s now complete enough to use, provided that you don’t blow on it too hard. Here it is: pmarket-maker.herokuapp.com. Enjoy!
You can create a market, and then create a set of options within that market. Players can make buy and sell limit orders on those options. You can close an option and pay out a specific amount per owned share. There are no market makers, despite the pun in the name, but players start with 1000 internet points that they can use to shortsell.
EDIT 2023-02-25: Such a web app exists for real now, made as an actual product by other people who can devops and design UIs, it’s called Manifold Markets.
