Multiple members of those associated with The Chase have heard that GSN executives reached out to order a short, fifth season of The Chase last Fall. GSN pushed to order a six to nine episode fifth season of The Chase, particularly just around the time as originals Steampunk'd and Hellevator tanked.
However, those who are the head of production in the United States and the heads who own The Chase in the United Kingdom would apparently not let this happen, likely due to the fact that they want large orders like there have been the past two years or take the show to a network that would treat The Chase better rather than just ordering limited seasons. As of the past week and a half (post-New Years), GSN is still considering ordering an amount of The Chase episodes that would not be a large order like Season 3 (14 episodes) and Season 4 (20 episodes) saw.
The fourth season of The Chase, which aired all throughout the 2015 calendar year, was the highest rated season of The Chase yet for GSN (also the highest rated GSN original of 2015 in total viewers).
