David Pennock:

I believe it’s the largest prediction market created by number of outcomes (9.2 quintillion). We’re approximating a #P-hard problem to get the odds. More here. I believe v0.3 is faster and easier to use and with better social features.

The CrowdPark team have tested their social betting model in Germany, and they are now opening an office in San Francisco to boost their US expansion. You can bet with a virtual currency, and their business model is to monetize like a game. They have received funding from EarlyBird Ventures [PDF].

Here.

2010 was a warm year, despite record snow and ice in highly populated areas. Here is the message I provided on the expiry:

The NASA GISS GLOBAL Land-Ocean Temperature Index for 2010 averaged out to 0.6325 Celsius above baseline. The winning prediction is ‘greater than 0.6 Celsius (>0.6)’. Congrats to the winners, and to all participants for nudging closer to the truth.

I will list the 2011 question shortly.Â Many thanks to Inkling Markets for their generous hospitality.

Justin Wolfers pumped up the shitty, play-money prediction exchange run by InTrade/WSJ.

Shit here.

The fake-money exchange is pitiful, and to have a professor pumps up that shit is pitiful too.

UPDTE: That was the 2008 election. Fortunately, this crappy exchange is dead. Here’s Freakonomics on the 2010 election.

And Today’s Le Figaro features prediction markets, Emile tells me…

Â«Du coup, assure Ã‰mile Servan-Schreiber, on ne lit plus les articles de la mÃªme maniÃ¨re, un peu comme un analyste financier qui traque l’info pour ensuite s’en servir dans ses recommandations d’investissement.Â»
