1. Topics: national politics, major current events (frontpage news), prominent judicial affairs (celebrity trials), finance. Remark: I haven’t seem much blablating in the blogosphere about sports prediction markets, although they are the most popular of all the prediction markets. Am I misinformed? If “no”, do you have an explanation for that lack of coverage?
2. Substantial transaction volumes.
3. Market data available (including static and dynamic charts).
