Well, if you report the good news, you have to report the bad. Otherwise you turn into the MSM without the ad revenue. Like the New York Times.
Tradesports, after having run the Republicans Hold the House contract up to 0.55, has settled back in at even money, and the Iowa Electronic Markets are back to almost even between Hold and Lose. Given that the "Gain" contract is now up to .09, though, it's running 53-47 in favor of the Republicans. I'm not sure that all the people buying that contract know what they're buying, or maybe they just like a 10-1 shot to rise a little in the interim on some unknown news before they dump it.
Right now, if you could short in Iowa Markets, there'd be an arbitrage opportunity there, since the sum of the three contracts is a little over $1.
