Is Intrade out on a limb?

As I write this, Intrade gives the advantage to McCain over Obama and has the Republican party even with the Democratic party to win the election, whereas all the other prediction markets, meaning IEM, Betfair, and the NewsFutures play-money kind still favor a Democrat in the White House. That disconnect prompted Chris to wonder aloud whether Intrade is faster than the other markets to incorporate the latest polls, perhaps because of its &#8220-bigger liquidity&#8221-.

That&#8217-s an interesting reaction on several levels.

First, reactivity and accuracy are not to be confused for one another. Given that market prices are supposed to be more accurate and more stable that fickle U.S. raw polls (Berg et al, 2008), one should not necessarily be impressed by the market that is quickest to mirror the latest polls. I very much doubt that traders in the &#8220-other&#8221- markets have not heard about the latest polls giving McCain an edge. Rightly or wrongly – it is too soon to tell – they just gave those polls less weight that the Intrade traders apparently did.

Second, the argument from &#8220-bigger liquidity&#8221- is not receivable. Recently, Paul Tetlock analyzed Tradesports data in depth and found that more liquidity may in fact make the market dumber. He concludes: &#8220-In both sports and financial prediction markets, the calibration of prices to event probabilities does not improve with increases in liquidity- and the forecasting resolution of market prices actually worsens with increases in liquidity.&#8221-

My personal theory is that Intrade has a hair-trigger Republican bias which is not found in the other markets, because Intrade appeals to, and is marketed to, the more Republican-leaning segments of the U.S. population. In my opinion, the Intrade/Tradesports Republican bias was already evident in the 2004 election, as this analysis shows.

Of course, I may be completely wrong. In any case, I find today&#8217-s dual disconnect between the polls and most of the markets, on the one hand, and between Intrade and the other markets, on the other hand, to be two very interesting data points that should be duly recorded so we can come back to them later, with hindsight.

One day after BetFairs PR move, the very active event derivative traders are still very displeased by the new BetFair premium charges.

I have re-published yesterday&#8217-s BetFair Q &amp- A at the bottom of my previous post &#8212-because that&#8217-s the post that Google features, bringing in 300 people a day.

My analysis of this PR debacle:

  1. BetFair has a very complex information technology system, which is very costly, making BetFair less profitable than the fixed-odds betting operators (the big British bookmakers). They attack the problem with a dual approach: they try to lower the IT costs associated with each bet transaction (see FlyWheel Lite), and they try to spot and exploit their most costly customers (hence the premium charges).
  2. BetFair&#8217-s PR department is made up of friendly, knowledgeable and competent people. However, they are not up to date with BOTH the brand-new web publishing tools AND the brand-new behaviors associated with these tools. In other words, they don&#8217-t grasp the Web &#8212-where velocity and interactivity are 2 factors. Hiring a SEO is not the solution. BetFair should embrace the culture of the Web.

A FaceBook group has been created to protest the new BetFair premium charges.

Here are some BetFair traders&#8217- takes:

UPDATE:

A list of the Betfair forum threads about the new premium charges.

UK billionaire Andrew Black (the BetFair co-founder) owns and manages a stable of 30+ Thoroughbred horses, but cant stand anymore to hear about the event derivative traders whom he extracted wealth from.

Questions to InTrade CEO John Delaney about InTrade .NET and InTrade .COM

No Gravatar

– InTrade .NET is a play-money prediction exchange while InTrade .COM is a real-money prediction exchange. Is there an automated market maker linking the InTrade .NET prices (or bids) with the InTrade .COM prices?

– Why is it that you ask the consumers of InTrade .NET to sign the terms of use of InTrade .COM, which mentions that: &#8220-2.2.4 You may lose money on Exchange trades.&#8221-? – [Thanks to Deep Throat for that remark.]

– InTrade .NET has a very good charting system. Will the same charting system be implemented at InTrade .COM whose charts are absolutely awful? (See this comparison between the InTrade .COM charts and the InTrade .COM v2 charts.) I insist to say that this should be a priority.

– Will InTrade .NET have chart widgets, just like InTrade .COM and InTrade .COM v2 both have?

– Will InTrade .NET have closed contracts (which are very useful in the accuracy discussions), just like InTrade .COM and InTrade .COM v2 both have?

– Finally, it is stated on the InTrade .COM frontpage (in a text promoting InTrade .NET) that:

When Intrade.net goes out of beta it will become the new default but the current version of Intrade.com will be retained indefinitely.

How should we understand that? Does this mean that you are going to merge your play-money and real-money prediction exchanges? (Might not be a bad idea provided that full information is given on each prediction market.)

UPDATE: Deep Throat tells me that their techies are testing their new user interface on InTrade .NET, which deals with with play money, and then if everything works out well, they may implement the same user interface on InTrade .COM, which deals with real money &#8212-while maintaining the legacy InTrade .COM on a dedicated server, for the nostalgic users.

Folks, this is great stuff. I may blog about it, again, later on &#8212-if I find time.

You can blog about it on Midas Oracle, if you wish. Or comment on it, just below. Do register yourself.

Midas Oracle is the only publication that defends the event derivative traders (even when they are too sarcastic, boisterous, or annoying) -at the risk of infuriating the prediction market big brass.
