The header of my blog (above) shows the latest prices on offer in some of Australia’s election betting markets. I convert the prices to an implied probability of ALP win (factoring out the bookie’s profit margin, the so-called “overround”).
Time-series graphs appear as PDFs too, again see the header of the blog.
On the data themselves, the betting markets have been moving in a pro-Coalition direction over the last two weeks, with some movement around the time that recent polls have been released, showing that the Coalition would romp home. I think we’re still waiting on some post-carbon-tax polling, and how the betting markets digest that.
