The most accurate answer to ALPHA DRIVE ONE (ALD1) Junseo net worth in 2026 is that his exact personal wealth has not been publicly disclosed.
Unlike some established celebrities whose property holdings, business interests, salaries, or investments can be documented through reliable sources, Junseo’s personal finances remain private. There is no authoritative public financial statement confirming a specific dollar amount for his net worth.
That does not mean Junseo has no significant earning potential. Quite the opposite: his entertainment career stretches across several major stages of the Korean music industry. He has been part of 1THE9 and WEi, competed on Under Nineteen and Boys II Planet, worked as an actor, and eventually became a member of ALPHA DRIVE ONE.
Because of this history, Junseo has several potential income streams. However, group album sales, YouTube estimates, or general K-pop revenue figures should not automatically be treated as his personal income.
For that reason, Junseo’s net worth is best described as undisclosed rather than assigned an unsupported dollar figure.

Junseo’s Financial Overview
Junseo’s financial story is closely connected to the length and development of his entertainment career.
His first major public opportunity came through the survival program Under Nineteen. After finishing ninth, he became a member of 1THE9. The group officially debuted in 2019 and gave him his first experience of professional idol activities.
After 1THE9 ended, Junseo continued his career with WEi. The group debuted in 2020 under OUI Entertainment and allowed him to develop several years of experience in music releases, performances, promotions and fan activities.
His career entered another major phase when he participated in Boys II Planet in 2025. Finishing eighth in the final ranking secured his place in ALPHA DRIVE ONE.
ALD1’s debut created another significant commercial platform. The group’s debut mini album, EUPHORIA, generated more than one million first-day sales according to Hanteo data reported by Korean entertainment media.
However, those sales cannot be converted directly into Junseo’s personal net worth. Album revenue is affected by production expenses, distribution, agency arrangements, taxes, contractual terms and the number of people involved in creating and promoting the project.
This distinction is essential when researching celebrity net worth.
Junseo’s Main Income Sources
Music and Idol Activities
Music is one of Junseo’s most important professional income categories.
He has spent years working in the K-pop industry through 1THE9, WEi and now ALPHA DRIVE ONE. These activities can potentially generate income from album releases, performances, appearances, fan events, merchandise and other forms of entertainment work.
However, the amount an individual idol receives from group activities is not necessarily equal to the group’s gross revenue.
For example, if a group sells a large number of albums, the money generated does not simply get divided equally among the members. Companies, distributors, producers, retailers and other parties can be involved in the commercial process.
That is why ALD1’s impressive sales figures demonstrate commercial momentum but do not establish Junseo’s personal earnings.
ALPHA DRIVE ONE Revenue
ALPHA DRIVE ONE represents the newest major chapter of Junseo’s career.
The group was formed through Mnet’s Boys II Planet and debuted under WAKEONE in January 2026. Junseo joined seven other members in the new project group.
The debut album EUPHORIA performed strongly immediately after release. Reported Hanteo figures showed more than 1.13 million copies sold on its first day.
This is significant from a career perspective because strong group demand can create opportunities for future concerts, merchandise, advertising, fan events and additional releases.
Still, it would be inaccurate to say that the album made Junseo a specific amount of money unless his contractual compensation is publicly documented.
WEi Earnings
Before ALD1, Junseo was a member of WEi.
WEi debuted in October 2020 with IDENTITY: First Sight. Junseo remained associated with the group while building his experience as a performer.
His years with WEi potentially provided income through music releases, live performances, promotional activities and fan-related events.
However, there is no reliable public record showing Junseo’s cumulative personal earnings from WEi.
This makes it impossible to calculate a precise contribution from his WEi career to his current net worth.
1THE9 Career
Junseo’s professional career began even earlier with 1THE9.
He participated in Under Nineteen, a survival program designed to form a new idol group. His final ninth-place ranking allowed him to join the resulting group.
1THE9 debuted in April 2019 and released music during its active period before eventually concluding activities.
Although this was an important professional milestone, there is no publicly verified figure showing how much Junseo personally earned during his time with the group.
Acting Income
Junseo is not limited to music.
His entertainment career also includes acting. He appeared in the Korean drama Secret Relationships, taking on the role of Jung Da-on.
Acting provides a potential additional source of income because performers can receive appearance fees for television and other productions.
Nevertheless, Junseo’s individual salary for Secret Relationships has not been reliably disclosed through an authoritative financial source.
Therefore, it is more accurate to identify acting as a documented professional activity rather than attach a speculative salary to it.
Songwriting and Royalties
Songwriting is another potentially important part of Junseo’s financial profile.
Publicly available credit information connects him with songwriting and composition work associated with WEi material.
Songwriting credits can create royalty opportunities when songs are used commercially. The amount received depends on factors such as ownership percentages, registrations, usage and contractual arrangements.
Therefore, the existence of songwriting credits does not tell us how much Junseo has earned from royalties.
It does, however, demonstrate that his career may involve more than performing on stage.
Brand Deals and Commercial Work
K-pop artists can also generate income through advertising, sponsorships, fashion campaigns, fan events and other commercial activities.
Junseo’s increasing visibility through WEi, acting, Boys II Planet and ALPHA DRIVE ONE could create opportunities in these areas.
But individual endorsement contracts are often private. Unless a specific deal and compensation amount are publicly documented, it would be inappropriate to include an estimated endorsement figure in Junseo’s net-worth calculation.
Social Media Earnings
Social media is another potential source of income for modern entertainers.
An idol’s online presence can support promotional campaigns, sponsored content and fan engagement. However, follower counts and video views alone do not establish an individual’s income.
Third-party websites may provide estimated YouTube revenue, but those estimates generally relate to a particular channel and should not automatically be attributed to Junseo personally.
Consequently, social media should be treated as a possible revenue channel rather than a confirmed component of his personal wealth.
Early Life and Education
Kim Jun-seo was born on November 20, 2001, in Ulsan, South Korea.
He developed an interest in performing before entering the professional entertainment industry and eventually became involved in the trainee and survival-show system.
His participation in Under Nineteen became a major turning point. Instead of following a conventional route directly into an established group, Junseo gained exposure through a televised competition where trainees competed for positions in a new idol group.
This experience helped establish his professional identity before he later joined WEi.
Public information about his private education is more limited than his entertainment history, and his professional career remains the most extensively documented aspect of his biography.

Junseo’s Career Journey
2018: Under Nineteen

The survival program brought together young trainees competing for positions in a new group. Junseo ultimately finished ninth.
2019: 1THE9 Debut

The group officially launched in April 2019 with the mini album XIX. This marked Junseo’s first major experience as a professional idol.
2020: Transition From 1THE9
1THE9 eventually ended its activities in 2020.
Rather than leaving the entertainment industry, Junseo moved into another stage of his career.
2020: WEi Debut
Junseo became a member of WEi under OUI Entertainment.
WEi debuted in October 2020 with IDENTITY: First Sight. The group provided Junseo with a longer-term platform for music, performances, promotions and fan activities.
2021–2024: WEi Activities
During his WEi years, Junseo continued developing as an idol performer.
This period helped expand his professional experience and public recognition while giving him opportunities across music and entertainment.
2025: Boys II Planet
Junseo returned to the survival-show environment through Mnet’s Boys II Planet.
He ultimately finished eighth in the final ranking, earning a place in ALPHA DRIVE ONE.
2025: Acting Career
Junseo also expanded his entertainment work into acting through Secret Relationships.
The project demonstrated another side of his career beyond music and idol promotions.
2026: ALPHA DRIVE ONE Debut

Major Achievements
Junseo’s career includes several important milestones:
- Ninth-place finish on Under Nineteen
- Debut with 1THE9 in 2019
- Membership in WEi from 2020
- Continued experience in K-pop performance and promotions
- Participation in Boys II Planet
- Eighth-place finish in the final Boys II Planet ranking
- Selection for ALPHA DRIVE ONE
- ALD1 debut with EUPHORIA
- Acting role in Secret Relationships
- Documented songwriting-related credits
One of the most notable commercial milestones connected to his newest group is ALD1’s debut album performance. EUPHORIA surpassed one million copies in first-day sales according to Hanteo figures reported by Korean entertainment outlets.
That achievement provides useful context for Junseo’s current career environment, but it should not be confused with his individual bank balance.
Assets and Lifestyle
There is currently insufficient reliable public information to create a verified list of Junseo’s personal assets.
Some celebrity websites estimate net worth by adding supposed cars, homes, watches or luxury purchases. Such methods can easily produce misleading results when ownership has not been confirmed.
For Junseo, there is no strong public evidence establishing a specific portfolio of houses, vehicles or investments that can responsibly be assigned a monetary value.
The safest approach is therefore to avoid presenting rumored possessions as confirmed assets.
His professional lifestyle is likely influenced by the demands of being an active K-pop performer, but details about his personal spending habits remain private.
Personal Life
Junseo generally keeps his private life separate from his professional activities.
Most publicly available information concerns his career, group memberships, music and entertainment work rather than personal relationships or financial matters.
He is not publicly documented as married, and there is no reliable basis for making claims about a private relationship unless supported by a credible source.
For a net-worth article, keeping this distinction clear is important. Personal rumors should not be used as evidence of financial status.

This table represents career development rather than confirmed dollar-based net-worth growth. No reliable public source currently provides enough financial data to calculate Junseo’s wealth for each year.

Why Junseo’s Exact Net Worth Cannot Be Confirmed
The biggest challenge in calculating an idol’s wealth is the difference between revenue and personal income.
Suppose an album generates millions of dollars in sales. That does not mean the artist receives the same amount.
Revenue may first pass through retailers, distributors, production companies, agencies and other business arrangements. Costs associated with recording, manufacturing, marketing, choreography, music videos, staff and promotions can also affect the final amount available for distribution.
The artist’s contract then determines how applicable income is divided.
Junseo’s situation is even more complex because his career includes multiple groups and professional activities.
His 1THE9 earnings, WEi activities, acting work and ALD1 career should not simply be added together without verified compensation data.
This is why a responsible celebrity-finance article should separate documented career achievements from unverified financial assumptions.
