Recently, The Copenhagen Test emerged as the most-viewed streaming series on Peacock after an impressive rise through the streaming charts in only a matter of days, and even caught some of its audience off-guard by becoming the #1 show on Peacock with just a few days since its release.A lot of people appearing in previews prior to release were doubtful about whether or not the show would hold up. Some believed that the plot may confuse audiences, while others questioned whether or not it would translate well to the screen. After initial trailers dropped, many viewers were skeptical about the project until it started receiving word-of-mouth support and exposure once viewers started watching regularly. Subsequently, viewership has continued to build momentum.With Simu Liu and Melissa Barrera leading the cast of The Copenhagen Test, the series revolves around a first-generation analyst, played by Simu, who is shocked to discover he has potentially been the victim of a mind hack. As a result of this, he is unable to escape from an unknown individual or entity who can tap into both his vision and hearing. This means that Simu must find a way to maintain his ordinary routine, all while keeping an eye out for the unknown entity who may be tracking him.

While those numbers aren't perfect, they demonstrate that the majority of people are enjoying the series and prompting many to urge Peacock to submit their renewal for a second season. At present, there has been no response from Peacock. Trends for typical streaming platforms indicate they will evaluate the viewership of a series over the period of two - three weeks before making a renewal decision. Therefore, fans will have to exercise patience while awaiting definitive information regarding the future of The Copenhagen Test.Why The Copenhagen Test became so popular so fastA major reason that The Copenhagen Test gained popularity is due to the celebrity status of Simu Liu. Most people are now aware of him because of his role as the superhero Shang-Chi in the Marvel film, and the Legend of the Ten Rings. After that, he went on to work in multiple other projects, such as Last Breath and Arthur the King, leading to even greater awareness of his name.Another well-known actress who is being talked about currently is Melissa Barrera. She gained fame from her role in the Scream series. It was evident that there was going to be curiosity about the show due to two of the lead actors already having a certain amount of fame attached to them.Another reason the show took off is that people were looking for something fresh in the spy-thriller space. Peacock has added many new shows in the last year, but not many of them caught fire the way this one has. The Copenhagen Test is easy to binge since the episodes are not too long, and the story moves at a steady pace. Even if someone starts it casually, they often end up finishing a few episodes in the same night. That kind of viewing pattern usually helps shows rise on streaming charts very quickly.

One of these shows, Supernatural, is one of the largest shows that have moved from Netflix to Peacock in the last year, and many fans have continued to view it. The fact that The Copenhagen Test was able to pass Supernatural highlights how successful this new show is.Another show that has had success over the last few months is All Her Fault, featuring Sarah Snook. This show had a huge rise to success early in 2025 and held on to that spot for quite a long time before falling out of the number one position slightly. Bugonia, a film from Yorgos Lanthimos, is currently the most popular movie right now in the movies category, followed very closely by Him, a horror film produced by Jordan Peele. Movies like Shrek, while older, are still performing well and retaining positive momentum.With such a wealth of new and previous material being released at once, it is all the more remarkable to see how The Copenhagen Test has been able to emerge. The series appears to be gaining popularity for good reasons, and if this pace continues, Peacock may have more confidence in renewing the series very soon.Peacock has made all episodes of The Copenhagen Test available to stream.
