I would say better-than even chances that sites like intrade gain prestige in the next decade

and betting on predictions will become common ( 90% that there is a student at 75% or so of high schools in 2020 that will take bets on future predictions on any subject, 40% that >5% of US middle class will have made a bet about a future prediction)

naive guesses based largely on http://www.fivethirtyeight.com/2009/11/case-for-climate-futures-markets-ctd.html

I predict further that I will continue to post on LW at least once a month next year (90%) and in 2020 (50%)

Is there any comparable website that you were posting on in 2000 and continue to post on today? I agree that LW is awesome, but web communities have a short shelf life (and a tendency to be superseded as web technology improves).

Probably a good reason to adjust the estimate down. On the other hand I was 11 in 2000 so I wouldn't have been on this kind of site anyway, and conditional on the prediction that news-betting becomes more prestigious rationality almost certainly will.

Point taken, with the real point being that I have no sense of how long a decade is, so I'll adjust that down to a 20%

I have stayed in touch with a different web community for five years, with which I'm still in touch, although only barely at the level of once a month. So my odds for awesomeness overcoming shelf-lifes may be higher than for most.

    Kind of vague, but I suppose it's not too hard to do a search and note that the NYT only mentioned Intrade a few times in the 2000s and more in the 2010s.

    I have no idea how one would measure this one. I'm sure that at any high school you could find a student willing to wager with you on any damn topic you please.

  3. Not including a prediction for middleclasses. Already true if you count sports, as many prediction markets such as Betfair do.

    Agree with orthonormal that this is seriously over-optimistic. The only site I even use today that I did in 2000 would be Slashdot, and I haven't commented there in a dog's age.

I probably meant for claim 3 to exclude sports.

Well, then you're using a variant definition of prediction market, and before I can feel confident judging any prediction of yours, I need to know what your idiosyncratic interpretation of the phrase is.

I agree that I wasn't making the most coherent claim, and since it's been a long time I can't guarantee fidelity of what I originally intended.

But my best guess would be, trying to phrase this as concretely as possible, was that I meant to predict that either

a) sports betting agencies would expand into non-sports venues and see significant business there

or b) newer betting agencies not created to serve sports would achieve similar success

I would be "disappointed" if "non-sports" meant something like player movement between teams and "excited" if it meant something like unemployment rates and vote shares in elections.
