assuming that this isn't raiding accounts as a prelude to shutting down (as a number of forumers claim)

Not that I think that it is impossible for this to be the truth; I just think it unlikely:

(My reasoning for the jump is that a year doesn't suffice to drain the dormant accounts at $60 a year, but two would drain most, and then the shut-down becomes a real possibility; and Intrade seems to've long been a marginal concern independent of any ill effects from this fee change.)

Contracts on "the market ceases to operate and this contract becomes worthless" should be seriously underpriced, no?

(edit: whoops, didn't even look at the links)

Those are PB.com predictions; Intrade.com doesn't have such contracts as far as I know and I certainly wouldn't buy any contracts if they did, the new fees aside.
