Nowhere is it disclosed that the WSJ Political Market is trafficked by special bots.

Justin Wolfers in the Wall Street Journal:

The Wall Street Journal is running a political futures market where you can “trade” on candidates’ future performance or see how others assess their chances.

An important remark is that the WSJ Political Market is, number one, a play-money prediction exchange (unlike the real-money prediction exchanges that are studied closely by the economists such as Eric Zitzewitz, and which are the topic of the rest of the WSJ Op-Ed), and, number two, that the WSJ’s play-money prediction exchange is driven by an automated market maker linking InTrade’s real-money prediction markets and a set of play-money prediction exchanges powered by the InTrade-TradeSports software (Play-Money InTrade, FT Predict, WSJ Political Market, National Journal Ex., Rasmussen Ex., Real Clear Politics Ex., etc.).

I am all for:

1. play-money prediction exchanges;
2. automated market makers helping liquidity in play-money prediction markets (e.g., Inkling);
3. the InTrade-TradeSports software used for play-money prediction markets;
4. InTrade-TradeSports selling its software to the big media (and, later, to Fortune-500 corporations, I suppose).

My only remark is that, if the InTrade-powered sub-exchanges do indeed use a new kind of automated market marker, it should be disclosed and detailed. That’s all what I’m saying. I’m just asking for the truth.

WSJ Political Market:

Welcome to the WSJ Political Market
November 29, 2007

The WSJ Political Market is an exchange marketplace [???], like a stock market [no... like a derivative exchange], except the “stocks” traded are political candidates and the currency you’ll use is fantasy [and except that some "stocks" expire to zero... thus they cannot be qualified of "stocks"]. Users can trade contracts that are tied to the outcome of future political events, from individual state primaries to the general election.

Each participant is given ten thousand fictional WSJ dollars (WSJ$10,000) upon registration. You can use this fictional money to buy and sell contracts – buy if you think the outcome is likely, and sell if you don’t. The price of a contract reflects the market’s assessment of how likely its is to happen. Your performance will be tracked and the best traders will be ranked on our Leaderboard page[.]

Futures markets such as this one have been gaining attention for their powerful predictive capabilities. The prices on the WSJ Political Market reflect trading from millions of users via our partner InTrade. [Mysterious Irish sentence!!!!!] Sift through the data to gain unique insights into the 2008 Presidential race.

FAQ

Q: I am new – how do I get started?
A: Once you open an account then go to “Trading and Quotes” tab and select the market you are interested in then you are ready to start making predictions.

Q: I think an outcome isn’t going to happen, but you don’t have the opposite result, what do I do?
A: That’s the beauty of a Political Stock Exchange, to predict against an outcome you simply sell the contract.

Q: But I don’t own any contracts, how can I sell something I don’t own?
A: When you sell a contract you’re actually making the opposite prediction to buying the contract[.]

Q: Am I guaranteed the quoted price when I place an order?
A: We execute all orders automatically. When your order is entered it competes with others in a queue based on the best price and then the time the order was received by the Exchange. Orders at the same price joining the queue before yours have priority. Therefore we cannot guarantee the price until your order reaches the exchange and is executed at your quoted price or better.
