Smarkets: An Amazon price rank prediction market

After my post this morning about the Y!/O’ Buzz Market Game, I was pointed at Smarkets, a prediction market for Amazon products.

Each new product added becomes a “stock”.
Chart_pie If a product’s Amazon’s sales rank improves, its stock price goes up. And vice-versa.

Here’s this month’s Oprah’s Book Club choice: “A Million Little Pieces”. Very nice!

Oh, and it’s YARoR (Yet Another Ruby on Rails) site… who’d have thunk it.

  • Thanks for the plug Rael. Hope you like it. I just launched it so be gentle with any bugs you might find.

    Yep, it is YARoR site. And it includes tags; imagine that. The tags are nice because you can group products together to compare their performance. For instance, being able to compare at a glance how Ruby on Rails books are doing compared to Java books. ; )
