According to a report from Sports Business Daily, the International Olympic Committee is weighing a proposal to add skateboarding and BMX halfpipe and park as events at the 2020 Games in Tokyo. IOC Sports Director Chris Dubi expects the IOC to recognize the International Skateboarding Federation by the end of the year, which would be a big step towards the sport's inclusion.
While BMX cycling made its debut as an event in 2008, skateboarding and halfpipe events have failed to make the cut, despite the popularity and acceptance of tangential sports such as snowboarding and slopestyle that have thrived at the Winter Olympics.
Also of note from the article is the fact that the IOC is considering adopting sport climbing, which goes contrary to a decision in May when the IOC decided not to adopt the sport.
While most are likely familiar with the halfpipe, the park competition is slightly more obscure so I've put an example from the 2013 X Games below:
