Would InTrade or BetFair have done a better job predicting how many people would see the Barack Obama infomercial?

As I disclose on the other blog (Midas Oracle .COM), the HubDub traders wrongly thought that the (Socialist) Barack Obama informercial would have be seen by &#8220-more than 50 million&#8221-. No, no, no, no. It was 33.5 million, according to Nielsen. The HubDub traders were too optimistic.

Would the InTrade or BetFair traders have done a better job? Jesus, that&#8217-s a difficult question. Which boils down (mainly, but not uniquely) to whether some experts on TV business were quoted in the media with some predictions. To investigate that, I have run a Google News search for news articles published before October 30. I haven&#8217-t seen any expert predicting how many viewers would get that infomercial. However, here&#8217-s what I spotted in the New York Times article published in the morning preceding the airing of that infomercial:

Ross Perot, the last presidential candidate to run similar programming, broadcast eight long infomercials to an average of 13 million viewers, with one of them getting 16.5 million viewers.

Hummm&#8230- Obviously, the HubDub traders were too cocky with their &#8220-50 million&#8221- figure&#8230- but should we blame them when, obviously (too), the Barack Obama situation circa 2008 is very different than the Ross Perot situation circa 1992?

The HubDub traders were not informed by the Ross Perot history. They simply made the bet that the Barack Obama infomercial would get as many TV viewers as the Third Presidential debate got (56.5 million). They predicted in a gregarious fashion. They lost.

I don&#8217-t think that the BetFair or InTrade traders would have done better. Do you?

I like the way they color this electoral college map &#8212-with 5 colors only (simplicity is good). It is very clear and usable, I believe. You can see 6 states in gray (&#8221-too close to call&#8221-). I am heavily betting on Barack Obama for Florida and North Carolina. There will be a good payoff, next Tuesday &#8212-maybe. :-D

Explainer On Prediction Markets

–

A prediction market is a market for a contract that yields payments based on the outcome of a partially uncertain future event, such as an election. A contract pays $100 only if candidate X wins the election, and $0 otherwise. When the market price of an X contract is $60, the prediction market believes that candidate X has a 60% chance of winning the election. The price of this event derivative can be interpreted as the objective probability of the future outcome (i.e., its most statistically accurate forecast). A 60% probability means that, in a series of events each with a 60% probability, then 60 times out of 100, the favored outcome will occur- and 40 times out of 100, the unfavored outcome will occur.

Each prediction exchange organizes its own set of real-money and/or play-money markets, using either a CDA or a MSR mechanism &#8212-with or without an automated market maker.

Prediction markets produce dynamic, objective probabilistic predictions on the outcomes of future events by aggregating disparate pieces of information that the traders bring when they agree on prices. These event derivative traders feed on the primary indicators (i.e., the primary sources of information), like the polls, for instance. (Garbage in, garbage out&#8230- Intelligence in, intelligence out&#8230-) Armed with these bits of information, the speculators then trade based on their anticipations, which will be either confirmed or infirmed. Hence, the prediction markets (which are more than just an information aggregation mechanism) are a meta forecasting tool.

The value of a set of prediction markets consists in the added accuracy that these prediction markets provide relative to the other forecasting mechanisms, times the value of accuracy in improved decisions, minus the cost of maintaining these prediction markets, relative to the cost of the other forecasting mechanisms. According to Robin Hanson, a highly accurate prediction market has little value if some other forecasting mechanism(s) can provide similar accuracy at a lower cost, or if very few substantial decisions are influenced by accurate forecasts on its topic.

Here are short excerpts of the Forrester report on enterprise prediction markets and companies that provide software for enterprise prediction markets (e.g., Consensus Point &#8211-see the full list of providers at the bottom of this post).

–

The Forrester executive summary:

The &#8220-wisdom of crowds&#8221- is capturing the attention of corporate strategists across the globe, and, as a result, many are now looking to prediction markets — speculative markets in which traders collectively predict future events — to generate collective intelligence. For enterprises, prediction markets bring unique value: They focus on the future, aggregate diverse information pools that can be applied to multiple decision-making domains, create streams of actionable data suitable for executive decision-making, and can often cut through corporate politics and pressures at lower cost than traditional forecasting methods. Market researchers will, however, need to have an active hand in the management of these mechanisms, ensuring strong management support, the right incentives for traders, and a focus on appropriate questions. When executed properly, the value to the enterprise is enormous- as a result, Forrester believes that prediction markets will ultimately find a permanent home in the market research toolbox.

The definitive proof that HubDub is an indispensable prediction exchange. [*]

As I told you, I am blogging as often as possible on the other blog (Midas Oracle .COM) about the 2008 US presidential elections as seen thru the eyes of the prediction markets. As I wrote there this morning, I have just found out a truly interesting set of prediction markets at HubDub. (I wasn&#8217-t able to find its equivalent on InTrade, BetFair, or NewsFutures.) It&#8217-s trying to predict where the Dow Jones will be, come November 4, 2008. (As you may remember, the deeper the financial crisis, the more likely it is that Barack Obama will be elected president of the United States.)

As of this morning, the Dow Jones is barely above the 8,000 level (8,175.77), and the futures say that the stock market will rebound, at least in the first hours. However, I am bearish. I would bet that the Dow Jones will stay around the current level (or lower) until Election Day. In other words, I am betting on the red, on the chart below.

At what level will the Dow Jones Industrial Average close on Election Day?

[*] And if Emile (whom we highly respect, overall) is pissed off by that statement, then, great, that&#8217-s a cool unintended collateral consequence. :-D

How to break a successful prediction exchange in less than one week

Posted on by

Whiskey Kilo (a Hollywood Stock Exchange trader):

Change is one thing, breaking the whole site and acting like its nothing happened is another. The whole concept of trading movie stocks, movie bonds and options have taken a backseat to making sure you can blog, add friends, and “Schmooze”.

The old portfolio page was color coded and extremely easy to understand, you instantly knew if you were making H$ or losing your shirt. Now the current portfolio page is a small box, one colour, light grey on a white backround and the type is half the size of the font here, also you can only see 12 stocks at any given moment. Whoever OK’d this part of the site has to have never traded any shares online before.

From what I can gather, there was a beta version of this 3rd generation of the game, but no one paid any attention to the any of the feedback, two days after this new rollout, HSX.com started calling this new version a beta game, and what HSX staff there is say that portfolios are now their priority. However the only things that really work right now are the blogs, which pay H$10,000 a posting, adding friends pays traders H$1000, Online Polls, and Schmoozing. which paid initially H$1000, but now pays H$100 per reply. The only reason I see for paying traders to blog is to bring more eyeballs to the garish 728?90 and 300?225 ads on each page to pump the number of advertising views on HSX. But if this is part of the grand scheme here, I can’t see Gold coin or Forex advertisers closing sales from a bunch of 13 years because all the veteran traders have left in disgust.

I welcome Jed [*] to read the HSX Support page: http://www.hsx.com/cms/forums/support and look around, I shudder to think this all is going to be a B-School case study on how to kill a successful site in under a week.

At inception, I created an Internet usability category, and, since, I have published many Jakob Nielsen stories. Many wondered why I would bother. Now, the Midas Oracle readers can understand why.

Competitive Forecasting (the brand which NewsFutures Emile Servan-Schreiber is so sanguine about) is probably more than a generic mark, it might well be a descriptive mark -provided X, Y and Z.

Tom W. Bell – (a law professor who have been following the field of prediction markets for years):

My two cents on “competitive forecasting”: It probably rises above a merely generic mark, which could never be protected, because it is not the commonplace name for the service to which it refers. It more likely qualifies as a descriptive mark, and as such could be protected only if “secondary meaning” were proven. In other words, the claimant would have to show that by dint of long exposure to its use in a commercial context, consumers had come to understand the mark not as a mere description but as the name of the claimant’s service. Whether or not “competitive forecasting” can meet that test remains a question of fact, of course.

Caveat: I speak only of U.S. law, though most common law countries follow similar principles.

–

Interesting.

PostScriptum: Put aside that discussion about branding, I like NewsFutures as a play-money prediction exchange, and I have come to realize, e-mailing Emile privately, that he is one of the man I would go for to have an in-depth foray into the real value of the prediction markets (going beyond accuracy, onto utility) &#8212-ironically, the kind of stuff that Robin Hanson is researching more seriously these days (PPT file).

The new Hollywood Stock Exchange website (recently redesigned) sucks as much as an indigestible fruit cake.

HSX-sucks.com &#8212- I predict that somebody will soon register this domain name.

Many HSX event derivative traders have complained to me privately about the website redesign: they hate it more than they hate the recent financial bailout. One HSX trader went off on the Prediction Markets group discussion area at LinkedIn. Today, another HSX trader is writing a long prosecution of the HSX website redesign. Read it in all, and spot the many comments at the bottom, from fellow HSX traders.

The root of the problem is Alex Costakis &#8212-the director of HSX. My assessment of him is that he doesn&#8217-t get the Web. He is as clueless as a maggot trying to play Jazz. He is not an open person, and the Web is all about openness. This guy is a drag on HSX. I predict he will lead to HSX&#8217-s death.

The only 2 persons that could lead to a revival of HSX are Max Keiser or Nigel Eccles. Let&#8217-s hope that Cantor Fitzgerald will call them for help.

UPDATE: See the comments.
