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.

How do InTrades prediction markets work, and are they really accurate?

Thanks to the InTrade person who uploaded the first CNBC segment on YouTube, and fixed the initial technical problem.

I renew my asking for the second CNBC segment to be uploaded at YouTube, too. [If someone else than InTrade does it, please hit me with the YouTube URL. Thanks.]

My analysis:

  1. InTrade-TradeSports CEO John Delaney does a good job explaining the mechanism of the wisdom of crowds.
  2. They cut professor Justin Wolfers too short. It&#8217-s a nuclear disaster &#8212-once again. Justin Wolfers is an admirable and ultra friendly person, a great prediction market researcher, a good prediction market analyst, and a wonderful blogger, but his TV appearances are, so far, totally crappy. The guy needs to hire a publicist who will teach him to flatten his Australian accent and to talk straight and plain &#8212-to go to the point real quick.
  3. &#8220-It seems like someone at CNBC decided at some point that they would NEVER address the legality issue.&#8221- – Dixit Deep Throat.
  4. After the broadcast of the video shot in Ireland, the camera goes back to the TV set, and, at this point, the comments from the journalists and the guest (Steve Forbes) show that they still don&#8217-t understand fully the prediction markets. They don&#8217-t have the right facts, and their analysis is not crystal clear.
  5. Overall, a good explainer on the prediction markets &#8212-taken into account that CNBC is an entertainment media. For deeper explainers, see the Wall Street Journal, the Financial Times, or Midas Oracle.

Now that Joe Biden is the Democratic vice president nominee, what to think of Justin Wolfers August 1st column for the WSJ?

– The good point is that he dealt well with the fact that the VP prediction markets fed on primary indicators that are less reliable than the ones used for the political elections.

– The bad point is that, at the time he wrote up his column, Virginia governor Tim Kaine was the favorite of the InTrade VP prediction markets. The others were, in decreasing order, Evan Bayth, Kathleen Sebelius, and then&#8230- Joe Biden. So, the critic reading his column today could say that the prediction markets are oversold to a gullible public and that a prediction market bubble ready to pop up is forming under our very nose.

– Now, we know that Barack Obama made his decision while vacationing in Hawaii (less than 2 weeks ago). That&#8217-s only from that date that the VP prediction markets started generating probabilistic predictions worth quoting. The trick is that Justin Wolfers (and the other prediction market analysts) didn&#8217-t know that, on August 1st. (PDF file)

– I don&#8217-t regret my decision not to publish about the VP prediction markets. I&#8217-d look like an idiot today.

We are now 100 members of the Prediction Markets group at LinkedIn, and that includes InTrade CEO John Delaney and many other prediction market luminaries (scholars like Eric Zitzewitz or David Pennock and practitioners like Nigel Eccles, David Perry or Adam Siegel). So, when Robin Hanson emerges ou

Don&#8217-t forget to tell LinkedIn to show the groups you belong to on your profile &#8212-that&#8217-s the damn purpose (to get the web visitors to navigate from one profile to another from within the prediction market community).

By default, the groups are not visible on your profile. YOU HAVE TO CHANGE THAT OPTION. Do it now. Hurry up. (What? It&#8217-s not done, already? What are you waiting for?)

The second CNBC video on InTrades prediction markets is up and running.

In both segments, the appearance of Justin Wolfers is a nuclear disaster. They cut him ultra short. Maybe because of his strong Australian accent, I don&#8217-t know. But the end result is bad. It&#8217-s a pity. Justin Wolfers would have had many interesting things to say.

PS: InTrade people, please, put that on YouTube and tip me when it is done, so I can embed those videos.

– Please, put that on YouTube, and then give me the YouTube URL. I&#8217-ll embed the video in another post.

– Who is that guy that they will interview later on, Jason??? [UPDATE: Serge Ravitch]

My observations:

  1. Quite upbeat. Almost an advertisement for InTrade.
  2. No mention whatsoever that InTrade is illegal in America.
  3. On the website, they call InTrade a &#8220-political futures market&#8221-.
  4. The InTrade critic was Barry Ritholtz. They just showed his blog. He wrote that the trading on InTrade is &#8220-pitifully&#8221- small.
  5. The first prediction market analyst they want to hear is InTrade CEO John Delaney. The second is professor Justin Wolfers. And that&#8217-s all.
  6. Steve Forbes asked whether &#8220-this thing&#8221- (InTrade) predicted Joe Biden &#8220-weeks ago&#8221-. The answer is that InTrade predicted Joe Biden some days ago.
  7. Joe Kerner put an emphasis on liquidity, whereas the emphasis should have been on the market as the mechanism that delivers a collective verdict.
