Betfair's machine learning algorithm failed to identify Luke Ashton as a high-risk gambler despite his history of self-exclusion and extreme betting patterns, contributing to his gambling addiction and subsequent suicide in April 2021.
Luke Ashton, a 40-year-old father-of-two, died by suicide on 22 April 2021 while struggling with a gambling addiction. He had been using Betfair since 2012 and had previously self-excluded from the platform in 2013, 2014, and 2016. Despite this history, Betfair's machine learning algorithm failed to identify him as a high-risk gambler. In the months before his death, Ashton's gambling escalated dramatically - he averaged 55 bets per day in January 2019, rising to a peak of 1,229 bets in March 2021 when he deposited £2,500 in a single day. He lost £5,000 in the month before his death and had previously taken out £18,000 in loans in 2019 to fund his gambling. The algorithm was designed to detect risk levels and track customer data, particularly for those who had self-excluded, but it failed to flag Ashton despite his extreme betting patterns of up to 100 bets per day. Betfair's managing director Richard Clarke admitted at the coroner's inquest that 'Looking at Luke's activity in March 2021, it does look like we should've done more.' Around 10,000 customers were placing more bets than Ashton on Betfair's busiest days in March 2021, highlighting the scale of high-frequency gambling on the platform.
