2015 Q3 NGDP prediction market


Up until now we've used Inkling Markets as our prediction market provider, but they've recently been bought by Cultivate and will be offline from December. The finance questions for Cultivate will be run through a new website called Alphacast.

At the moment, members are unable to post their own questions. However, I've received some really helpful input from their technicians and one of their early trials will be a prediction market for UK NGDP. How cool is that! This is good timing because the Office for National Statistics release the second estimate of the National Accounts on Friday November 27th, and this will contain the first look at NGDP for Q3.

The question is: What will be the quarterly growth rate of NGDP for the UK economy for Q3 2015?

The market will only be running for a week, and as ever there's (relatively) large arbitrage opportunities early doors. So get trading!

Update: (27/11/15):

The correct answer is 3.4%.

Here's the Alphacast chart:
