The Coachella Effect based on analysis of YT data from 108 countries
TLDR; Tracking YouTube Charts from 108 countries on a daily basis revealed that the change Coachella brought to BINI's fandom was not a fleeting buzz, but rather the potential for the emergence of a sustainable fan base extending beyond the Philippines.
------------------------------------
We analyzed YouTube view counts for BINI, a Filipino girl group scheduled to perform at this year's SUMMER SONIC, across 108 countries to investigate how their Coachella appearance last month affected fan viewing behavior. This may indicate a growing fandom outside the Philippines.
[What Changed Before and After Coachella?]
The top graph shows views for the Philippines only, while the bottom graph shows views for the other 107 countries, with different scales on the vertical axis.
In early March (March 1st-4th), the average daily worldwide view count was 343,000.
With the release of the Blush MV on April 9th, views jumped to 1,136,000, and reached 1,255,000 on the first day of Coachella.
Afterward, view counts gradually decreased, but remained at an average of 631,000 per day even in early May (April 28th-May 8th), after all events had concluded.
Compared to before Coachella, there's still an 83.8% increase, suggesting that it wasn't just a fleeting trend.
【What was the effect of Coachella?】
The 3.1x spike on the release date of the Blush MV (April 9th) occurred before Coachella even began.
It seems the MV, not Coachella itself, created the initial impact.
So what did Coachella bring?
A point of comparison is the Unang Kilig MV, released a month earlier.
Unang Kilig also recorded a 2.7x spike on its release date (Note 1), but its momentum halved just two days after the peak.
In contrast, the Blush MV + Coachella combination took 11 days to halve.
The continuous Coachella stage footage, social media sharing, and media coverage are likely contributing factors to sustained fan viewing.
In addition, the lyric videos released immediately after Coachella (Step Back: 360,000 views, Sugar Rush: 340,000 views, Tic Tac Toe: 270,000 views), Dance Practice (460,000 views), and all nine episodes of BINI Diaries likely served as a gateway for new listeners, further slowing the decline in interest.
Based on the data, the effect of Coachella appears to have been more about "sustaining the buzz created by the music videos for several days" than "generating an explosive initial surge."
[Which countries retained their fans?]
Looking at the increase before and after Coachella by country provides clues to the geographical spread of the fandom.
Indonesia had the highest retention rate at +199.5%.
Indonesia also ranked highly as a "starting country" for cross-border hits in a previous analysis by our lab.
The young population, with over half under 30, has not only become a receptive environment for "rediscovering" past hit songs, but has also served as a starting point for new K-pop songs to spread from Southeast Asia to the rest of the world.
In the case of BINI, this "fertile ground for young audiences to accept new artists" likely contributes to its high retention rate.
Thailand saw a +176.8% increase, followed by the UK at +151.8%, and South Korea at +151.0%.
The Philippines saw a +76.2% increase, but because its initial audience size is overwhelmingly large, this translates to an increase of approximately 230,000 views per day in absolute terms.
There seems to be a common thread among countries with high retention rates.
Indonesia, Thailand, and South Korea all had a certain level of viewership even before Coachella.
For fans in these countries, Coachella may not have been "an opportunity to learn about BINI for the first time," but rather "an experience of seeing their favorite artist perform at a global festival."
That experience may have reinforced their loyalty as fans.
[The Structure That Coachella Has Begun to Change]
Of the 39.67 million views worldwide from March to May 2026, the Philippines alone accounted for 34.05 million views, or 85.8%.
BINI's YouTube views are almost entirely generated by the Philippine fan community.
However, Coachella has shown signs of change in this structure.
Total views from the 107 countries outside the Philippines increased by +143%, from 39,000 views/day in early March to 95,000 views/day in early May.
This pace significantly surpasses the growth in the Philippines itself (+76.2%).
While the 85% figure is still overwhelming, it could be interpreted as a sign that the fandom is beginning to grow outside the Philippines.
Tracking YouTube Charts from 108 countries on a daily basis revealed that the change Coachella brought to BINI's fandom was not a fleeting buzz, but rather the potential for the emergence of a sustainable fan base extending beyond the Philippines.
Whether this emergence will continue is a topic worth continuing to track.
[Note]
The analysis period is from March 1st to May 8th, 2026.
Note 1: Welch's t-test (a statistical method comparing the mean of the 7 days before and after an event) yielded p = 0.029.
The p-value represents the probability of such a difference occurring by chance, and generally, a value less than 0.05 is considered statistically significant.
