Why ‘XO, Kitty’ Season 4 Should Be A Foregone Conclusion With Its Blockbuster Start in Top 10s

XO, Kitty, the beloved To All the Boys spin-off, returned for its third outing on March 29th, and the first-week numbers are officially in. 

Whenever a show hits its third season on Netflix, we usually start talking about the “decay curve.” Will audiences remember where the plot left off? Will they bother tuning in? That’s not a worry for executives or the crew with XO, Kitty. Its loyal fanbase has turned up season after season, and that remains the case with season 3. 

It should be surprising, the show’s faithful tracks every movement of the show, and thanks to its writing (even if it’s sometimes controversial) does enough to keep people coming back. Sprinkle in some solid cameos from To All The Boys, and you’ve got a winner. 

Looking at the data Netflix just dropped, alongside the daily metrics from FlixPatrol, season 3 has retained 90% of its audience from season 2, and while it’s not growing in viewership, it’s got an incredible hold over those who do watch, something that’s incredibly important when it comes to renewals.

While Netflix hasn’t officially greenlit Season 4 yet, the cast and crew are already making their hopes known during their recent press tour.

Speaking in an exclusive interview with Swooon, showrunner Valentina Garza hinted that the Season 3 finale leaves the door wide open for the future. She noted that while Kitty and Min Ho have reached the end of one chapter, they are “absolutely also at the beginning of a journey with all that they’ve learned,” teasing that there are still “so many more [relationship] milestones for them to potentially cover”.

When analyzing Netflix renewals, there are a bunch of factors but some core ones for XO, Kitty are:

• Cost vs. Viewership: YA shows naturally cost less to produce than CGI-heavy sci-fi epics like 3 Body Problem or Stranger Things. Hitting 12.9 million Views out of the gate is an excellent return for this budget tier.
• Completion Rates: A 9% season-over-season viewership drop tells us the completion rate is incredibly high. People who start this show finish it although we never get to see this number beyond third-party metrics.
• Global Appeal: The FlixPatrol data confirms it plays phenomenally well in non-English speaking territories, giving it massive global utility.

Here is a deep dive into the Season 3 premiere numbers and why a Season 4 renewal is practically inevitable.

The Global Top 10 Numbers: XO, Kitty has excellent audience retention

Let’s get right into the meat of it. In its premiere week (March 29 to April 5, 2026), XO, Kitty Season 3 debuted at #1 on the Global English TV list, pulling in 55.9 million Hours Viewed, which translates to 12.9 million Views (or CVE – Completed Viewing Equivalents).

To understand just how strong that is, we have to look at the season-over-season comparisons:

• Season 1 (May 2023): 14.2M Views (Week 1)
• Season 2 (Jan 2025): 14.2M Views (Week 1)
• Season 3 (Mar/Apr 2026): 12.9M Views (Week 1)

While raw “Hours Viewed” took a dip from Season 1’s 72 million, we have to account for runtime. Season 1 was a flat 5 hours long, whereas Season 3 clocks in at 4 hours and 20 minutes. This is exactly why Netflix shifted to the “Views” metric—it levels the playing field.

Dropping from 14.2 million Views to 12.9 million Views in a Season 3 premiere represents a remarkably small drop-off of just ~9%. Most YA (Young Adult) shows on Netflix bleed 20% to 30% of their audience by their third season, with some shows as of late even hitting 30-60%!

XO, Kitty, retaining over 90% of its core audience, proves there’s plenty more juice left to squeeze. 

Over the coming weeks, we’ll be keeping an eye on its cumulative chart to see if people stick around beyond just the initial launch:

FlixPatrol Heatmaps: Dominating the Globe

Another positive point for XO, Kitty: it’s popular everywhere. Looking at the FlixPatrol data over the past week, the geographic footprint of this show is staggering.

• Latin America: The show hit #1 almost immediately in Argentina, Brazil, Chile, Colombia, and Mexico. Even as of today (April 7th), it’s holding the #1 or #2 spot across the region.
• Europe: Absolute domination. It topped the daily charts in France, Germany, Italy, Spain, Poland, and the Nordics.
• Asia & The Middle East: Strong #1s in India, Egypt, Israel, and the Philippines.

While it has started to slip slightly in the US and UK (dropping to #4 and #3 today, respectively), the fact that a relatively low-budget YA rom-com can instantly command the #1 spot in most countries globally is exactly the kind of ROI (Return on Investment) that grants a renewal.
