History

Historical Context

The PGA Tour launched the FedEx Cup in 2007, creating golf’s first season-long playoff with a $10 million bonus pool and prompting SportsLine to run 10,000 outcome simulations for the finale. Rule tweaks in 2008 and 2013 refined points and exemption stakes, while the 2019 pool rose to $70 million, cementing data-driven wagering that today powers the 2026 CJ Cup Byron Nelson simulations.
