Smarkets ever changing odds can cause a discrepancy in liability

← Back to blog

Before we launch into this article, we want to make one thing clear. This is not an attempt to discredit Smarkets or discourage our users from using Smarkets. In fact, we recommend all our members make the switch to using Smarkets as their primary exchange after completing most of the Novice offers.

The aim of this blog is to bring to light an issue which some of our more eagle eyed members have already spotted. Often, when using Smarkets as your exchange, you may find that the liability that is presented on the Heads&Heads add bet form does not match the liability shown on Smarkets, despite the odds being the same.

Now this has nothing to do with the quality of the calculations done within the Add Bet form on Heads&Heads. Rather, it is the result of the way Smarkets updates their odds. To explain, we need to start by looking at how Smarkets (and all bookmakers & Exchanges) present odds on their website.
