Previously: The InTrade predicton markets on the viability of InTrade won’-t reveal *ANYTHING* about the future of InTrade.

TradeFair, soon.
Not a bad idea, but not the best idea they could have.
The EPS prediction markets were a better idea, because they have many more primary indicators.

InTrade CEO John Delaney:
Our #1 untapped resource is the vast collective intellect that we have only started to use. Harnessing the “-wisdom of the crowd”- has a very big potential role in improving all of our lives. If we do it, we all have a voice and will feel part of the solution as well as the problem. We can solve some wicked problems, like climate, resource, growth, social, and economic challenges. In simple terms, there exists between us the best information on how we solve our key challenges. If our leader’s embrace and permission new systems like prediction markets to operate in a transparent prudent way I am convinced that we can contribute in no small part to the solution.
Recall, that US Department of Defence believed a prediction market could provide valuable information on growth, risks and social issues. Hundreds of academics, dozens of Fortune 500 companies, and millions of people believe that prediction markets can help provide valuable information on economic, financial, social and environmental issues.

I have already expressed my deep skepticism for this kind of grandiose discourse.
Today, if I may, I would like to ask these questions to John Delaney:

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

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 —-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…- Intelligence in, intelligence out…-) 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.

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.

HSX-sucks.com —- 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 —-the director of HSX. My assessment of him is that he doesn’-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’-s death.
The only 2 persons that could lead to a revival of HSX are Max Keiser or Nigel Eccles. Let’-s hope that Cantor Fitzgerald will call them for help.
UPDATE: See the comments.

To the question asked in the title of this post, some have answered by the affirmative (“-Prediction Markets Have a Big Role to Play”-). In my view, it is wrong to overvalue the real social utility of the prediction markets.
As of today, we can plainly see 2 things. Number one, the prediction markets are a tool of curiosity. People have heard about InTrade thanks to numerous news articles (where some prediction market researchers who get the InTrade historical data for free pump up the prediction markets as God’-s right arm on Earth). At crunch time, the people teased by all this publicity flock to the InTrade website to satisfy their curiosity about the state of the horse race. Number two, a subset of the general population (made up of educated people who believe in the virtues of markets) use the prediction markets as a tool of convenience. Instead of spending long hours reading the various outputs by the pollsters and the commentariat, these people just check InTrade on a daily basis, because they know that it is primarily (but not only) an information aggregation mechanism. InTrade sums up the news of the day, so to speak. Hence, these people (in the know about how to benefit practically from the wisdom of crowds) don’-t have to spend time gathering and analyzing the news of the day.
To the question asked in the title of this post, I’-ll answer “-no”- —-unless one of my readers can educate me more about the following issues:

I Told You So.

The NYT writers discusses 2 (different?) issues.
–
#1. There was market arbitrage opportunies in the recent past between InTrade and BetFair —-unlike 4 years ago, and contrary to the laws of economics.
– The price of the Barack Obama event derivative was cheaper on InTrade than on BetFair and the Iowa Electronic Markets. Conversely, the price of the John McCain event derivative was more expensive on InTrade than on BetFair and the Iowa Electronic Markets.
–
–
#2. The NYT writer reports (without linking to it) the findings of the InTrade investigation about the behavior of their unnamed “-institutional investor”-.
– InTrade CEO John Delaney suggests that that institutional investor:
– Justin Wolfers’- PHD student remarks that that institutional investor is not making an effort to shop around for the best prices, within each InTrade political prediction market.
