Political Strategy and Prediction Markets

No Gravatar

Strategists who want to know when a strategy is effective should pay attention to the market. Here is one losing strategy Edwards should drop:

According to Intrade.com, every time the Edwards presidential campaign (via Elizabeth Edwards) tries to engage Coulter in a catfight, his price plummets. His lowest point was after Elizabeth Edwards&#8217- &#8220-surprise&#8221- call-in to Hardball with Chris Matthews in June 2007.

Mr. Giuliani might want to check out intrade before he takes anymore calls mid-speech.

Robin Hansons annoying insistence on distinguishing prediction markets from betting markets

Jed Christiansen has more on the 2007 Consensus Point conference on prediction markets&#8230-

Robin Hanson

Robin gave a quick addendum to his earlier talk, where he focused on the cost-value space of a prediction market. He described an evolution from betting markets, which have negative cost (aka profit) though little value to an organisation, to future prediction markets. Fully evolved prediction markets will certainly have a cost to operate, but the output could have tremendous value to a company.

Is it the end for US-based betting exchange HedgeStreet?

The End

Is HedgeStreet closing shop?

Yesterday, I re-published on Midas Oracle the e-mail sent to the HedgeStreet traders and prospects. (Curiously, this e-mail was not sent to me, even though I am in their listing.) They wrote that their overhauling would lead them to propose soon &#8220-new and exciting products&#8221-. Well, I found that interesting.

However, today, one of my Deep Throats ( :-D ) is telling me that it is all bullshit, actually.

  1. They are packaging HedgeStreet for a closing/fire-sale. Everyone is leaving, and only a skeleton crew is left.
  2. The CFTC has minimum capital requirements, which HedgeStreet is not able to sustain. They were burning $1m a month on 5k-10k of revenue, then tightening and tightening&#8230- There&#8217-s just no money left.
  3. UPDATE: Russell Andersson was laid off about 3 months ago. VP of finance leaving, VP of compliance leaving, etc. It is falling apart.

We will see.

Should a betting exchange be a content provider, too?

Should BetFair have acquired TimeForm (the publisher of horseracing ratings, form guides and analysis)? Niall O&#8217-Connor (a betting market expert) thinks that there is a &#8220-strategic mismatch&#8221- between the two. I&#8217-m republishing his hatchet job, below. (I hope he won&#8217-t mind that I quote him in full, this time.)

At the end of November 2006 Betfair acquired Portway Press Limited, the owner of Timeform, the world-renowned brand involved in the publication of horseracing ratings, form guides and analysis. It was suggested at the time that the acquisition had cost Betfair somewhere in the region of ?15m.

At the time of the acquisition, Betfair announced that Timeform would retain full editorial independence, but that it would bring capital investment, technology, marketing and communication skills to the table.

On publishing its results for the year ended 30 April 2007, Betfair said that Timeform had &#8220-made a small loss in its first five months of trading after acquisition&#8221- but that it was confident that it would generate positive returns in the near future.

One can only speculate as to what the strategic thinking behind the acquisition was. Presumably it was believed that an association with the prestigious Timeform brand would make Betfair&#8217-s horse racing services more creditable- whilst at the same time affording cross-marketing opportunities.

Flawed logic at best&#8230-.

First, it is widely acknowledged that Betfair has given rise to, and nurtured, a culture of trading. Betfair traders do not typically run to form books, but rather, they let the Betfair market guide them, in the belief that it reflects all known information. (Betfair, with its lower transactions and information costs, provides its traders with a more realistic assessment as to the chance of longshots and the true probabilities of runners in a horse race- the favourite longshot bias is typically diminished, if not eroded).

Second, there is a strong case to be made that the incorporation of Timeform experts into Betfair&#8217-s horse racing radio service, has merely served to undermine the exclusiveness of the Timeform brand. Indeed, in situations where the Timeform expert&#8217-s selection fails to win, the brand is exposed to ridicule.


It is debatable whether the rather highbrow and serious research provided by Timeform, has any strategic fit with the Betfair trading culture.
And one is therefore left to conclude that Betfair has not only misjudged the market for Timeform products, but also, demonstrated a serious lack of awareness of its own customers.

The hard truth of a failed plan is that the core values of the Timeform brand have been diluted through its association with a commercial betting exchange.

Hummm&#8230- I won&#8217-t make any comment on TimeForm (which I&#8217-m not familiar with). However, I will say this, generally speaking.

  1. A betting exchange has no business being a content provider.
  2. Except if the betting exchange can and will develop some very special content that the traditional media can&#8217-t or won&#8217-t provide, and that is of high strategic interest.
  3. The difficulty, though, is that exchange executives and managers don&#8217-t have the first clue about how to set up and run a credible and popular media.
  4. That said, it could well be that some exchange-sponsored or -run media projects will succeed &#8212-due to some highly talented project managers (the exception, not the norm).

Which way does Robin Hanson blow? When he was not involved, he had negative comments on internal prediction markets. Now that he is more involved (keynoting at a vendor conference), he has positive comments. Could it be that The Professor is biased? :-D

#1. Justin Wolfers on the 2007 Consensus Point conference

Robin Hanson tells me that he is now (back to) bullish on prediction markets – he saw real evidence of real firms implementing prediction markets and taking them seriously.

#2. Jed Christiansen on the 2007 Consensus Point conference

Robin [Hanson] gave a fairly standard introduction to prediction markets lecture that some may have seen at other events or downloaded from his website. It was a good overview of the topic.

The question and answer period was the most interesting part with Robin. He was asked about manipulation, and provided some fairly convincing answers that manipulation shouldn’t be a worry (at least with the correct incentives.) Robin described the situation in terms of sheep and wolves. Sheep aren’t that knowledgeable- they are trading for any number of reasons, and are the “noise” in the marketplace. Wolves take advantage of that, and consequently they look for markets with lots of sheep. With better information, the wolves will easily have plenty to “eat.” The net result is that those noisy markets are accurate markets.

Another concept he talked about was creating a “fudge” account. Let’s say you want to weight one set of traders more than another, or simply want to “move” the forecast in one direction or another- create a “fudge” account to conduct those transactions. If after the account has been running for a while and it’s positive, you’ll know you’ve done a good job fudging. But if the fudge account is negative, you don’t know more than the market so just stop fudging and leave the market to itself. It’s a great idea, and fairly easy to implement.
