Combinatorial Prediction Markets – by Robin Hanson

Video + Slides

Slides from Hanson&#8217-s site – PPT file

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.

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.

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.

One Wall Street / Chicago fanboy hopes that political prediction markets will soon be proposed by the established derivative exchanges, who work more professionally than InTrade (in his view).

InTrade-TradeSports has a web server misconfiguration problem, and CEO John Delaney has a character problem.

No Gravatar

As I wrote at the time, the InTrade-TradeSports websites were unavailable, last Friday, August 29, 2008, during a good part of the morning.

InTrade-TradeSports is not only an event derivative exchange, but also a webspot that non-trading people often consult to get the latest market-generated probabilistic predictions. Last Friday, in addition to the traders, many people visited InTrade just to see what their prediction markets were saying about who would be John McCain&#8217-s pick as Republican vice presidential nominee. InTrade-TradeSports CEO John Delaney has said that that Friday saw 10 times more web visitors than any usual peak day, and that their server bandwidth was not large enough to cop with all solicitations. It is well known in the media business that servers should be configured many times bigger than for the normal usage &#8212-so as to accommodate exceptional peak times, when some impacting news break. My sentiment is that the InTrade-TradeSports technical team has probably not fully anticipated the growth of the InTrade-TradeSports followers.

As the result of this black Friday, some traders complained. One trader (Todd) started a thread on the InTrade e-mailing list. Unfortunately, Todd spiced his message with sarcasm. Which immediately irked John Delaney, who responded to the complaint, but also added a twisted line in effect inviting Todd to close his InTrade account.

That remark offended another InTrade-TradeSports trader (Lucy Vega), who talked back to John Delaney:

BetFair and InTrade-TradeSports are de facto monopolies (with 95% of the total business on their geographical zone, according to my estimation), and their direct competitors have far less liquidity, thus making them uninteresting for the big traders like Todd.

If John Delaney were really sincere in his wish to see the US public prediction market industry becoming legalized and experiencing a big growth in the coming decade, he should refrain from making offending remarks to his customers &#8212-even when those clients started the feud with some sarcasm of their own. This kind of bullying behavior could attract the attention of the US regulators in a negative way, which is exactly the reverse of what is needed at this time.

I can understand that John Delaney is sometimes upset by some of his ultra-demanding and sarcastic customers. However, as I said, the real-money prediction exchanges are in a situation of being de facto monopolies, where their market-generated information is of high social utility, which creates a social responsibility for the executives and managers of these prediction exchanges. You don&#8217-t insult and castigate a blogger who exposes a scandal. You don&#8217-t censor the CNBC reports. You don&#8217-t ask a complaining customer to close his / her account. All those things are big no-nos.

UPDATE

I am re-publishing an old post of mine, as an appendix, to respond to some comments:

Dan Laffan of InTrade has just given me permission to republish his e-mail(s) to Todd Griepenburg:

Todd,

We will absolutely not continue to be part of or facilitate any further diatribe with you on these issues.

If you are not satisfied that we
1. Have listened to your comments
2. Have replied to same and
3. Will take or have taken whatever corrective action is within our power and/or appropriate
then we reluctantly suggest that you consider closing your account on the exchange (or cease using it until our service meets your expectations). We say “reluctantly” as we do not wish to see any member leave, but we seem to be causing you immense dissatisfaction which is not our intention.

We will promptly close your account and return any funds you have in your account at your request. We await your decision and instruction.

Best regards,
Dan

InTrade to Todd

UPDATE #2

For the full information of my readers, InTrade-TradeSports&#8217-s behavior is not the worst behavior that a prediction exchange can have towards an annoying customer. I am aware of another real-money prediction exchange who does close the accounts of the customers whom they view as problematic (and that, without citing any reason) &#8212-as opposed to just asking somebody to leave.

UPDATE #3:

Todd&#8217-s new message to John Delaney

This post is a very short review of their new website. I might publish a deeper review, later on.

The log line is that InTrade CEO John Delaney has ingested all the innovations that HubDub has brought to the prediction market scene since January 2007 (e.g., long and rich prediction market webpages that are indexed by the search engines, and use of social networking to boost trading) and has asked his technological team to clone those innovations for InTrade. This is great. I also appreciate that their charting system is satisfying. (The advanced charts seem to be of the right size, I have noticed. Neither too small, nor too big.)

On the negative side, the execution is not as good as it should be &#8212-and I&#8217-m polite. But to be fair with them, they say their website is still in &#8220-beta&#8221- &#8212-so let&#8217-s give them time to improve their work.

Overall, it&#8217-s a good move, and it shows, as I have said for months, that Nigel Eccles of HubDub is having a profound impact on the prediction market industry.

UPDATE: I forgot to mention that InTrade.net presents probabilities expressed in percentage, not prices, which they also took from HubDub.
