InTrades prediction markets on skyscrapers

– the opening date of the Freedom Tower in New York-

– the opening date of the Chicago Spire.

I like that. I remember requesting this kind of prediction markets two years ago, to another exchange &#8212-to no avail.

Exchanges should create much more delivery date prediction markets &#8212-about buildings, cars, software, etc.
