Market Analysis
The bear case driving these exceptionally low odds reflects multiple structural challenges. Na faced a decisive defeat in the 2021 Seoul mayoral by-election, losing to Oh Se-hoon who currently holds the position and would likely seek re-election in 2026 as the PPP incumbent. Seoul mayoral races typically favor incumbents with strong approval ratings, and Oh Se-hoon’s administration has maintained relative stability. Additionally, Na would need to win a contentious PPP primary against an incumbent from her own party, a scenario that rarely occurs unless the incumbent faces major scandals or chooses not to run. The Democratic Party also fields competitive candidates in Seoul, creating a challenging general election environment even if she secured the nomination.
The bull case requires a dramatic shift in Seoul’s political landscape. Oh Se-hoon would need to decline running for re-election or suffer a catastrophic approval collapse that makes him vulnerable in a primary challenge. Na maintains name recognition and conservative credentials that could position her as a viable alternative if the current administration stumbles significantly on issues like housing affordability, which remains Seoul’s most pressing policy concern. A major corruption scandal or policy failure by Oh before the PPP primary selection process (typically held 2-3 months before the June election) could open the door.
Key catalysts to monitor include Oh Se-hoon’s re-election announcement expected in early 2026, PPP primary procedures scheduled for March-April 2026, and Seoul’s housing policy outcomes through 2025. Na’s own political positioning within the party and any moves to build a mayoral campaign infrastructure in 2025 would signal serious intent. Current polling for Seoul mayoral preferences won’t emerge until late 2025, but tracking Oh’s approval ratings and housing price trends will provide early indicators of whether an incumbent challenge becomes remotely feasible.

Frequently Asked Questions
Why would Na Kyung-won challenge Oh Se-hoon in a primary when they’re both from the PPP?
She likely wouldn’t under normal circumstances, which explains the near-zero odds. This market only becomes viable if Oh declines to run or faces unprecedented political damage that makes him vulnerable to an internal challenge.
How did Na Kyung-won perform in her previous Seoul mayoral race?
Na lost the 2021 Seoul mayoral by-election to Oh Se-hoon by approximately 15 percentage points, demonstrating significant electoral weakness even in a race that favored conservatives following the previous mayor’s scandal.
What would need to happen for these odds to move significantly higher?
Oh Se-hoon would need to announce he won’t seek re-election, or a major scandal would need to emerge by late 2025, combined with Na actively building campaign infrastructure and leading in hypothetical PPP primary polling against alternative candidates.
