I’ve got a few posts coming soon on the innovation topics I’ve been discussing more recently, but prediction markets have really been the hot topic with the current election. Here are a few issues I find interesting:

Obama on InTrade

The recent nomination of Sarah Palin as Republican VP candidate seemed to have changed the dynamics of the race, and she has certainly sucked up quite a bit of media attention (both positive and negative).

What I find curious is the results on the InTrade prediction markets. Specifically, over the past day and a half there have been some really interesting swings on the Obama (and McCain) contracts.

I can absolutely understand that the candidates are getting closer. But Obama dipping below 50%, and then McCain going above Obama are pretty big steps! I’m surprised they happened without a particularly major event taking place. That said, I have a few reasons/thoughts:

• Manipulation: It’s certainly not unknown, but is certainly hard to detect. (Because it comes down to intention instead of action). But when I read Mike Linksvayer’s post at Midas Oracle noting that the Obama-President and DemNominee-President weren’t consistent, I do tend to think that it might be an irrational or potentially manipulative trader. That said, at least on InTrade the two contracts are now about equivalent for McCain, but about 2.5% different for Obama.
• Trader bias: In the discussions to Mike’s post, Nigel makes a good point that other real-money exchanges (such as Betfair and the Iowa Electronic Markets) still show Obama as a favorite. IEM currently has the Winner-Take-All, aka probability market, at 55/45 Obama. Are the traders on InTrade biased somehow? (Again, this could link back to manipulation depending on their motivations).
• Volatility: I’ll admit, I don’t check InTrade on a daily basis. But that said, it seems that the presidential contracts are quite volatile right now. Considering that no major events have been happening recently, I find it a bit odd that we’re seeing five-point swings in the matter of hours. Perhaps there is an extra sensitivity around the 50% price-point?

Minnesota and the IEM

Iowa is right next door to Minnesota (the state where I grew up), and Minnesota has a hotly contested election for a seat in the US Senate up for grabs this year. The Republican incumbent is Norm Coleman, and the Democratic challenger is comedian/radio-show-host Al Franken. Iowa Electronic Markets set up a market for this race, which I haven’t seen marketed particularly widely. Then again, it’s largely local/regional interest.

I find the difference between the IEM prices and InTrade to again be interesting in this market. In the local and US-legal-without-question market on the IEM, Coleman leads Franken 62/38. On InTrade, Coleman leads Franken at 57/43. There looks to be a more volume dollar-wise on InTrade, but IEM potentially has more local knowledge here.

Should be interesting to follow this in the next couple of months and see how and when the markets converge.

exchangeP

If you’re reading this blog, I figure there’s a decent chance you would have heard about TechCrunch and the TechCrunch50 conference. Fifty startups launched and demo’d their new sites and technologies over three days.

I got a kick looking at exchangeP. (Check out their site with demo video here.) Essentially they have created a niche prediction market site to determine the valuation of private companies, such as Facebook, LinkedIn, etc. While they describe it as a fantasy stock market, it’s really a fantasy prediction market since each “stock” is eventually cashed out.

Part of me is a bit incredulous that a site like this managed to get accepted at a conference like TechCrunch. Turning it into a profitable business seems to be something that they weren’t really considering.

But what really impressed and amused me was Mark Cuban’s feedback to them. (You can see it on the video.) The correct and impressive insight is that he remarked that it would never be big enough to turn it into a real-money site, so it wasn’t really viable as a business that way. Amusingly, he recommended that since they’ve already built their market tool/technology that they could then become a provider of technology for all of the people/companies that want to start prediction markets of their own.

So perhaps I’ll be adding them to my list of prediction market software vendors soon? Then again, they probably don’t know the diversity of prediction market software vendors out there today. From my first look at their site, it looks sub-standard.
