In brief
Los Angeles Mayor Karen Bass is favored to win re-election against Councilmember Nithya Raman in the November 3, 2026 runoff. Polymarket gives Bass a 64.5% probability, while Raman stands at 35.4%. A recent controversy over a fake poll briefly affected discourse but does not appear to have shifted betting markets.
Introduction
As the June 2, 2026 primary failed to produce a majority winner, Los Angeles voters will return to the polls on November 3 for a runoff between two progressive Democrats: incumbent Mayor Karen Bass and City Councilmember Nithya Raman. The race touches on homelessness, public safety, and trust in institutions. A bizarre episode involving a fabricated poll by the mysterious firm Median Strategies added a layer of drama but, according to available data, did not move betting markets.
What to know
The Los Angeles mayoral election is a nonpartisan runoff after no candidate secured a majority in the June primary. Incumbent Karen Bass, elected in 2022, faces progressive challenger Nithya Raman, a city councilmember representing a district that includes parts of Hollywood and the San Fernando Valley. Sources indicate the campaign is competitive, with both candidates holding press events and preparing for debates.
A fake poll, published by the now-defunct firm Median Strategies, claimed Bass led Raman by 12 percentage points. The poll was later retracted, with Median Strategies calling it part of an experiment to see how false information spreads (AP News). The Los Angeles Times reported the poll's release did not cause a noticeable bump in trading on competing platform Kalshi, and Polymarket did not immediately respond for comment (Los Angeles Times). The Hill noted the company shut down entirely, withdrawing all its polling data (The Hill).
Meanwhile, real campaign issues are emerging: Raman criticized Bass for pausing a street safety project on Forest Lawn Drive, which Raman says is politically motivated (ABC7). Bass and Raman are scheduled to face off in their first debate of the runoff, as confirmed by NBC Los Angeles (NBC Los Angeles).
The market numbers
Polymarket data as of August 20, 2026 shows the following implied probabilities for the election outcome:
| Candidate | Implied Probability |
|---|---|
| Karen Bass | 64.5% |
| Nithya Raman | 35.4% |
The total volume on this market is over $13.4 million, with $217,000 in liquidity. The market closes December 31, 2026.
The factors at play
- Incumbency and name recognition: Bass has served one term and benefits from higher profile and institutional support.
- Fake poll fallout: The Median Strategies incident may have briefly confused voters, but the lack of market movement suggests minimal lasting impact.
- Homelessness and public safety: Key issues in LA politics; Raman's progressive platform may appeal to the city's left base, but Bass has executive experience.
- Debate performance: With the first debate upcoming, any clear winner could shift momentum.
- Early voting: Starting in six weeks, early turnout patterns could signal the eventual result.
Our prediction
According to our analysis, the most likely outcome is Karen Bass. Polymarket currently assigns a probability of 64.5%, while our internal estimate is 65%. The difference is negligible because the market appears to have correctly priced in Bass's incumbency advantage and Raman's relatively lower state-wide name recognition.
Risks and uncertainties
- Surprise debate moment or gaffe: A major misstep could shift undecided voters.
- Turnout dynamics: Low turnout could favor Raman's more energized base, while high turnout might help Bass.
- Further fake news incidents: Another disinformation campaign could distort voter perceptions.
- Extremely close margin triggering recount: A very tight race could delay resolution and create legal uncertainty.
Conclusion
The 2026 Los Angeles mayoral runoff is a competitive but stable race. Karen Bass holds a clear advantage in betting markets and institutional support, while Nithya Raman runs a spirited campaign. The fake poll incident, while noteworthy, has not materially changed the race's dynamics. All eyes will be on the upcoming debate and early voting numbers.
