Predictit

I can across the following site:

[www.predictit.com]

It could account for the inertia here.

Very interesting given it is run Victoria Uni also.
At a guess I'd say there is some complex legal work for this to comply with US financial laws, given thats where it looks to be targeted.

Is anyone registered on that site to see the trading interface. I'm wondering if they have made any improvements based on the experiences with this site?

I tried but was denied based on locality

Certain US states aren't allowed to trade there either apparently.

Dammit, not available to kiwis so no chance to arbitrage
