Someone just hit a £150k fat finger loss.
Will Betfair allow it to stand?

Market was very quickly settled, then unsettled again. Chilli Queen was withdrawn but not removed from the market.
Lots of unpicking for BF to do here. Wonder how this will get settled...

Is this the biggest FF ever?
Got to feel for the responsible party. Hope no one here.

I seem to remember reading a post on here about a market resettlement after a chunky 1.01 bet which was the result of a compromised account. But is the exchange in the habit of reversing cock-ups?

Cheers, James. I don’t remember reading about that at the time.
Perhaps today’s fat finger at Southwell was the result of a similar technical issue, allowing a customer to exceed their maximum liability.
I mean, what are we talking about otherwise? Someone with 132K in their account and a bot running amok?

Wow, that's the record! There was something similar ~7-10 years ago at some irish racecourse, but it was a lot less, a few 10's of k.
My foilhatclub theory is that bf is the backer - motivates people to place more lay orders, good for advertising, and not so expensive if you do this once in a few years, they're getting back some of this in a form of commission and PC anyway.
