The different odds on Brexit are quite interesting.
According to Betfair markets, there is virtually no chance of a referendum being this year. Given that it's September, I can't disagree with that. Don;t really know why this market actually exists.
This initially seems strangely written as there is no "end of" in the title. But the extended info does state: "
Will the United Kingdom officially leave the European Union before the 29/03/2019 - 23:59:59?". Officially the UK will leave at 11 pm on the 29th March 2019.
Judging by that, there is a roughly 33% chance Brexit will be delayed. There is definitely a few reasons this could happen; another financial crisis, ineptitude of the British government, change in parliamentary arithmetic, etc.
But, Brexit means Brexit. There is only around a 10-15% chance of Brexit not occurring at all before 2022. Market's seem to think that there is an equal chance of Brexit being delayed rather than stopped. (Note - this isn't a big market so the take this is all with a pinch of salt).
The markets think there is a 60% chance that May will survive to see the UK leave the EU.
Only £3,716 matched here, so take this with a huge dash of salt, but there is a roughly 72% chance that the UK will leave the EU before a general election is held.
Lastly, there is a roughly 30% chance that there will be another EU referendum before 2020. Before 2020, as in, in 2019 or 2018. A referendum in 2019, after we leave but in the implementation period is reasonably possible. And even more possible is one in 2020 before the end of it, which isn't covered.
