[…] It turned out that Shiau&#8217-s predictions weren&#8217-t perfect&#8211-on average he was about 15 percent off on the sales of Nintendo&#8217-s DS and Wii, Sony&#8217-s PlayStation 3 and PlayStation Portable and Microsoft&#8217-s Xbox 360. But he also wasn&#8217-t that far off predictions from Wedbush Morgan&#8217-s Michael Pachter, one of the most quoted industry analysts, who himself had been about 10.6 percent off sales on the same consoles. And a month earlier, Shiau&#8217-s predictions had actually been better than Pachter&#8217-s. Shiau had been off by about 15.8 percent, while Pachter had missed by 34.9 percent. […] &#8220-Brian Shiau seems to have created a nascent and vibrant community,&#8221- said Chris Masse, the author of Midas Oracle, a blog [*] about prediction markets. &#8220-(There&#8217-s) a strong emphasis on using the SimExchange as an educational tool to teach youngsters about the stock and futures mechanisms. I like this a lot.&#8221- […] &#8220-The biggest obstacle is that most people don&#8217-t know what a prediction market is,&#8221- said Shiau. &#8220-So it&#8217-s very difficult to pitch it to someone without them understanding how a stock market (provides useful information).&#8221-

Last month was the first month the simExchange (the free to play video game stock market game) has traded monthly hybrid futures contracts to predict NPD US video game sales data. In this trial run, trading on the simExchange appeared to be relatively more accurate than expert predictions. To quickly review, the following table depicts actual sales as reported by NPD Group, the prediction by trading on the simExchange, the error of the simExchange&#8217-s forecast, the prediction by leading Wall Street firm Wedbush Morgan, and the error of Wedbush Morgan&#8217-s forecast:

NPD has released its findings for US April 2007 video game sales. The following charts compare actual sales numbers determined by the NPD Group with forecasts from market trading on the simExchange and predictions by leading Wall Street analyst Michael Pachter of Wedbush Morgan.

The simExchange did not trade monthly hybrid futures for game software this month. However, NPD&#8217-s Top 10 is still relevant for comparing how trading on the simExchange is forecasting lifetime, global sales of the games.

Although data is still limited, initial predictions on the simExchange video game prediction market appear to be relatively accurate (compared with traditional predictors), and in some cases, absolutely accurate (compared with the actual result). The prediction market out performed the analyst on every prediction in March and was split in April.

Predictions on the simExchange should become more accurate over time as more accurate players are rewarded with more virtual currency for their accuracy (thereby enabling them to form more predictions) and less accurate players lose virtual currency (thereby discounting their ability to form more predictions).

Joining and playing the simExchange is completely free and does not involve any real money. To play, sign up here.
