Barack Obama will finish off Hillary Clinton by June 15.

The End

Lawrence O&#8217-Donnell (a leftist journalist &#8211-but a good one, whom I appreciate):

A senior campaign official and Clinton confidante has told me that there will be a Democratic nominee by June 15. […] Yes, Clinton spokespersons publicly seem to be lost on gravity-free planet Clinton, but privately they know the end is near.

There&#8217-s a quasi consensus among the political pundits to say that Hillary Clinton will not be the Democratic nominee in November 2008.

Tim Russert:

That was Wednesday night. I have just watched NBC Nightly News this Thursday, and the same Tim Russert appeared with 2 white boards full of calculations, which all pointed to Hillary Clinton being toasted.

My general thoughts about the place of the political prediction markets in this primary election season:

  1. The weight of the political prediction markets in the US political scenery is close to epsilon. I have been monitoring Memeorandum (the Web&#8217-s best political news and opinion aggregator), and it has never featured one piece of political prediction market journalism &#8212-not only that, but none of the popular popular pieces, featured by Memeorandum, has ever mentioned the political prediction markets and their probabilities. The people who breathe politics on a daily basis (the experts and the bloggers) don&#8217-t give the first fig about the prediction markets. They couldn&#8217-t care less.
  2. The prediction market luminaries who predicted that the prediction markets were to become a tool used in political campaigns were dead wrong. I have never read that campaign staffers use actively the political prediction markets. Campaigns use private polls, only.
  3. Like in 2004 (when Howard Dean was crowned, early on), the prediction markets, at the start of the primary season, were incapable of foreseeing who would be each party&#8217-s nominee, ultimately &#8212-Barack Obama and John McCain both came out of the blue. But the polls and the political experts didn&#8217-t see them, too.
  4. Nothing surprising in that. While the idiots emphasize the supposed magical power of the prediction markets (using adjectives such as &#8220-fascinating&#8221- or &#8220-intriguing&#8221- when writing about them), the well informed people know for a fact that they simply aggregate information from the primary, advanced indicators and the opinions expressed by the political experts. Nothing more than that. The prediction markets are incapable of foretelling upsets, by essence.
  5. The last weeks were particularly interesting, in that regard, because the Obama-vs-Clinton polls have been of no interest &#8212-only the views of the political experts who could count in terms of delegates and super-delegates were of interest. The political prediction markets on the Democratic side, these last weeks, have been a reflection of the pundits&#8217- calculations.
  6. Outside of our blog, the only person who has aimed at practicing prediction market journalism is Justin Wolfers. He has understood the concept.
  7. I would have my own concept of prediction market journalism, and I don&#8217-t agree with the way he executes, but that&#8217-s a detail. The main thing is that he has gotten the concept. That&#8217-s what is important, and that&#8217-s what makes all the difference between Justin Wolfers and the HubDub bloggers (for instance). The concept. The concept. The concept. The idea is to center the narrative around the inputs given by the relevant prediction market(s) &#8212-not just gluing artificially news bits and a prediction market chart (or a link to a prediction market).
  8. InTrade, BetFair and NewsFutures are, in my view, the 3 prediction exchanges that matter for prediction market journalism &#8212-as of now.

Explainer On Prediction Markets

Prediction markets produce dynamic, objective probabilistic predictions on the outcomes of future events by aggregating disparate pieces of information that traders bring when they agree on prices. Prediction markets are meta forecasting tools that feed on the advanced indicators (i.e., the primary sources of information). Garbage in, garbage out&#8230- Intelligence in, intelligence out&#8230-

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 6 times out of 10, the favored outcome will occur- and 4 times out of 10, 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.

No GravatarSome of our luminaries have had their vapors and have boldly stated that the public [*] prediction markets would soon take over the free world and become the forecasting tool of choice for decision makers. Since our movement has started, in 2003, that has not happened &#8212-and will never happen (let alone in the year 2020). We were duped by those cocky misleaders. In the coming weeks, I&#8217-m going to try to launch a big intra-industry initiative to find the right usage for the public prediction markets. Stay tuned&#8230- and I hope I&#8217-ll get you on board with me.

[*] as opposed to the enterprise prediction markets, which is not the topic of my bombastic rant above, which is a horse of another color, and which would deserve a completely different analysis.

So no matter how you cut it, Obama will almost certainly end the primaries with a pledged-delegate lead, courtesy of all those landslides in February.

Why were the political prediction markets so wrong about Barak Obama and Hillary Clinton in New Hampshire?

&#8230-asks Slate&#8217-s Daniel Gross &#8212-via Mister Usability (Alex Kirtland), who needs to go and get his own gravatar.

So, I&#8217-ve been watching the action in one of the political futures markets this evening, Intrade. And the action in this prediction market has reinforced my opinion that these are less futures markets than immediate-past markets. The price movement tends to respond to conventional wisdom and polling data- it doesn&#8217-t lead them.

Throughout the day and into the early evening, while polls were still open, Democratic investors, mimicking the post-Iowa c.w. and polls, believed Obama was highly likely to be the Democratic nominee. The Obama contract was trading in the lows 70s, meaning investors believed he had a 70 percent chance of being the nominee, while Hillary Clinton contracts were in the 20s. […] At 6 p.m., this market had written Hillary Clinton&#8217-s entire presidential campaign off. At 9:30 p.m., it was calling a dead heat. What caused investors to change their minds so drastically in the space of a couple of hours? A few data points that went against the day&#8217-s prevailing conventional wisdom and polls. […]

See also Niall O&#8217-Connor&#8217-s assessment:

I am looking forward to the post New Hampshire Caucus, when all you prediction market advocates crawl out from under your stones. For the record at one point the market on Intrade and Betfair was suggesting that Obama had a 95% probability of winning the caucas- whilst Intrade had him at 77% to win the nomination.A case perhaps of both the foolery of crowds and, the market biting back.

New Hampshire will go down as the Black Wednesday of prediction markets and unless there is now objective transparent debate (as opposed to the usual biased sabre rattling) – prediction markets will be dead in the water.

My answer to Dan Gross&#8217- legitimate question and to Niall O&#8217-Connor&#8217-s snarky comment:

  1. Prediction markets are forecasting tools of convenience that feed on advanced indicators. When those advanced indicators are wrong, the prediction markets are wrong.
  2. If you prefer the polls or the pundits, your call &#8212-but polls and pundits were also wrong, this time, right? Required reading for mister Niall O&#8217-Connor: &#8220-New Hampshire&#8217-s Polling Fiasco&#8221- + &#8220-Analysis: pundits eat crow&#8220-.
  3. The ultimate forecasting tool would be a way to reverse our psychological arrow of time &#8212-so as to remember the future instead of the past. Only science-fiction writers and some imbecile ( :-D ) believe in that.
  4. The prediction market approach is to stick with the markets, on the long term. Take their successes. Take their failures. Unlike Donald Luskin and Markos Moulitsas, Chris Masse will not turn against the prediction markets when they fail punctually. What counts is the long series.
  5. My first point should be included in the prediction markets approach definition, in my view, but others (like economist Michael Giberson) might have different opinions.
  6. With respect to my first point, I bet that the prediction markets will never replace the polls as the forecasting tool of choice for political analysts &#8212-on that particular point (but not on a myriad of others), I break away from Justin Wolfers&#8217- irrational exuberance and I side with Emile Servan-Schreiber of NewsFutures (my preferred play-money prediction exchange). Prediction market reporting will have a function, indeed (as suggests Justin Wolfers), but not the dominant function.
  7. Going forward, prediction market journalism should emphasize relative accuracy (as opposed to absolute accuracy) &#8212-that is, comparing prediction markets with polls and pundits, which is what Robin Hanson has said from day one. Our good friend Niall O&#8217-Connor has difficulty to compute that, apparently. He should eat more fish. :-D

&#8212-

Justin Wolfers:

In a few years, we may regard the second half of the 20th century as the aberration in which the press used polls rather than markets to track political races,” Justin Wolfers, a business professor at the University of Pennsylvania’s Wharton School, wrote in an e-mail message. “And in the 21st century, we may return to the habits of the early 20th century, reporting on political races through the lens of prediction markets rather than polls.

Emile Servan-Scheiber:

1) The traders themselves are the first to look at the polls to inform their trades. So the polls are here to stay.

2) Our recent experience in Western Europe seems to indicate that the superior accuracy of markets over polls when predicting elections may be a U.S. artifact that isn’t so easily reproducible elsewhere. I’ve discussed this with Forrest Nelson of IEM [Iowa Electronic Markets], and apparently, ever since the Truman-Dewey polling debacle of 1948, U.S. pollsters have adopted a policy of reporting mostly raw numbers rather than projections based on sophisticated secret formulas, so they can’t be accused of manipulating opinion. However, raw numbers are notoriously unreliable when based on small samples, and Western European pollsters never report them, preferring instead to publish projections based on historically-informed statistical formulas. What we’ve observed in France and Holland is that it it’s very hard to beat the accuracy of such projections.

[I don’t make mine Emile Servan-Schreiber’s second point, but that’s a minor.]
