Slate compares InTrade, Iowa Electronic Markets and NewsFutures’ political prediction markets.

And it doesn’t look good for NewsFutures. While InTrade and IEM’s prices/probabilities are quite close, NewsFutures’ ones are out of whack, sometimes by a magnitude of ten points.

- Republican nominee

- Democratic nominee

- Next US President

- Political Party of the Next US President

- Should Slate add FT Predict in the odds comparison table?

- Slate has output an “explainer” on the legality of the prediction markets, which is the most insipid take I have ever read on Slate since the inception of this online magazine in the mid-nineties.

- See Slate’s 2007 guide to prediction markets, if you haven’t read it already.
