Took me about 45 or 50 minutes, start to finish. A lot of it was just cut-and-paste team names and info. Sixteen teams, each with a name, abbreviation, description, and starting price. A bit of general market information, an image uploaded. The market even includes a link to the official FIFA RSS feed that puts news headlines right on the market page! It was easy to manage.
If you are curious about how prediction markets work, Inkling makes it easy to get started.
(Still haven’t figured out how to embed the Inkling chart widget into a blog post, so the above chart is a static image that links to the market page at Inkling. You’ll have to click through to see the latest prices.
By the way, I also have an MLS Cup market running at Inkling too!)
