Xpree vs. Inkling Markets

No Gravatar

I am usually very sympathetic to Inkling Markets and Adam Siegel. I think they are the most professional prediction market consultants. However, I am more impressed by the recent Xpree hiring than by the recent Inkling hiring. Leslie Fine is a market design specialist and a fine researcher, who will bring credibility and expertise to Xpree. Very good coup by mister Mat Fogarty. I am very impressed. Wow.

ENDLESS VEEPSTAKES: Why you should never trade on VP prediction markets, and why their probabilistic predictions are as stochastic as Paris Hiltons daily dress picks.

As I explained in early June 2008, the VP speculations that appear in the Press should never be taken seriously. Most of them (and you don&#8217-t know which ones) are a big orchestration of pure lies aimed at creating publicity, or wicked lies in the form of trial balloons. The aims of the political campaigns are to:

  • creating suspense (sometimes false) so as to generate free publicity-
  • sending a positive message to the supporters of each VP candidate-
  • letting the Press do the vetting of the VP candidates-
  • flattering the political journalists by leaking to them-
  • sending out false leaks so as to preserve the surprise for the scheduled announcement day-
  • sometimes, buying time to impose the head of the VP search committee as the most serious VP candidate (remember Dick Cheney in 2000). [Psstt… Funny enough, in the 2008 election, Michael Moore is pulling for Caroline Kennedy. :-D ]

All that means that there are no good primary indicators for the prediction markets on the Democratic and Republican VP-candidate selections.

I want to offer 6 remarks:

  1. Not all prediction markets are created equal. Some have good primary indicators (e.g., the prediction markets on the presidential elections, thanks to polls), while some other prediction markets have unreliable primary indicators (e.g., the prediction markets on who will be on the ticket).
  2. The prediction exchange executives (like InTrade-TradeSports CEO John Delaney) will never tell you that, because their job is to sell their wares, of course.
  3. The public needs prediction market analysts, who can judge the quality of the primary indicators of one particular prediction market, so as to separate the grains from the shaft &#8212-reliable prediction markets from unreliable prediction markets. (A prediction market analyst has also other functions, which I will blog about later on.)
  4. A prediction market analyst should have a dual competency &#8212-in a vertical (in our example, US politics), and in prediction markets.
  5. The expertise in the vertical (here, politics) should be a major, and the expertise in prediction markets should be a minor. Take a look at these 2 mainstream media news stories: the one written Jack Shafer in Slate (which I linked to at the top of this post), and the one written by Justin Wolfers in the Wall Street Journal. Obviously, the one that shows the most mastering is the one written by Jack Shafer, an American professional journalist who follows US politics for a living.
  6. The consequence of that for prediction market journalism is that the writer should be an expert in a vertical, and the editor should be an expert in prediction markets &#8212-and not the other way around.

That said, I wish the very best of luck to our good friends Caveat Bettor (who is betting on Tim Kaine) and Nigel Eccles (who is predicting Joe Biden). :-D

UPDATE: My (informal) Democratic VP-candidate bet is on Kathleen Sebelius. Hint, hint.

UPDATE: Gawker says that Joe Biden would be a horrible choice. I agree. Plus, he has denied to be the pick. He could have lied to reporters, though.

UPDATE: New York Times publishes portraits of all VP candidates.

DEVELOPING&#8230-

NEXT: While InTrade CEO John Delaney is deceiving the journalists to sell his wares, Tom Snee of the Iowa Electronic Markets is telling them the truth: BEWARE THE VP-CANDIDATE PREDICTION MARKETS, THEY JUST AGGREGATE RUMORS.

Share:

Inexperienced Illinois senator (and presumptive Democratic nominee) Barack Obama should pick Kansas governor Kathleen Sebelius as vice president candidate to bring executive experience to the Democratic ticket -and to piss off Hillary Clinton (which will delight me).

Barack Obama + Kathleen Sebelius

New York Times publishes the portraits of all the VP candidates.

I have just read the article on Kathleen Sebelius&#8230- and that has strongly reinforced my view that she is the best pick for Barack Obama.

I am less opinionated as for what should be the ideal Republican ticket. (Wait&#8230- I want Ron Paul as VP candidate. :-D )

Arbitrage in the InTrade Dem VP Market

No Gravatar

There has been an unexploited arbitrage opportunity in the Intrade Democratic VP market (&#8221-2008 Democratic VP Nominee (others upon request)&#8221-). As the attachment shows, you can sell the slate of candidates for 123.2 (just sum the bids) while you will only have to payout 100. This possibility has existed for at least three weeks, and is particularly puzzling now given that the announcement is likely to occur this week.

What is also a bit odd is that Intrade has another market (&#8221-2008 Democratic Vice-Presidential Nominee (with Field contract)&#8221-) on the same outcome which includes a catch-all field contract which does not have the same arb&#8211-again see the attachment below. It is substantially cheaper to buy the field contract in the second market than the omitted candidates (Kaine, Sebelius, Hagel, Schweitzer, Gephardt, Kerry, and others) in the first market.

Any thoughts on why this is occurring?

OLYMPIC MEDALS: The Los Angeles Times cites HubDub -but not BetFair, TradeSports, NewsFutures, or YooPick.

Los Angeles Times

Could it be because the journalist had googled &#8220-Olympics&#8221- for his/her research?

HubDub is the only prediction exchange whose prediction market webpages are indexed well by Google.

SEO is key for marketing and P.R., folks &#8212-you see the evidence under your very nose with HubDub and the Olympics.
