Media Attention Driving Trades in L.A. Mayoral Election
Traders have committed more than $20 million to contracts tied to the upcoming Los Angeles mayoral election, making it one of the most active local government races in recent memory. Incumbent Karen Bass currently trades at 69% to win outright, while reality television personality and social media upstart Spencer Pratt sits at 26% on Kalshi, with Polymarket numbers somewhat mirroring this.
This highly media-covered political clash between a career incumbent in a Democratic stronghold city and an outsider celebrity generally seen as the Republican in the race (the race itself is non-party listed) has traders engaging with a flurry of activity.
Volumes surged after recent televised debates in which Pratt legitimized himself as an artful contender; his opponents suddenly had to take him seriously. Traders shifted positions rapidly, reflecting evolving public sentiment captured in a highly dynamic race.
Spencer Pratt Emerges as a Contender in Mayoral Race
Spencer Pratt, known for his role on a popular reality television show, launched his campaign following the loss of his family home in the Palisades Fires in Los Angeles in January 2025. Pratt and other residents who lost their homes in the sweeping urban wildfire blamed Karen Bass and her administration for failure to prepare for the fire or address it after it started. It became, and continues to be, a super-hot-button issue in Los Angeles.
Pratt channeled his anger at how the fire was handled, expanded it into other topics he bundled as Karen Bass’ management failures, and launched a campaign to unseat her as mayor in her re-election bid.
What began as a novelty celebrity campaign quickly caught fire with a segment of L.A. voters and drew local and national media attention. Pratt steadily climbed in published polls and prediction market odds from the low double digits to a serious challenger for a runoff spot with Karen Bass.
California runs open primaries (often called “jungle primaries) where anybody can vote for anybody, and the top two vote-getters advance to a general election face-off in November. In the case of the L.A. mayoral run, the top two vote-getters advance, unless a candidate wins an outright majority of the first vote, in which case there is no runoff.
Pratt’s Campaign Style Is Shaking Up the Political Norms
Pratt’s running a truly modern campaign, featuring dramatic AI videos created freely by his supporters, often depicting Pratt as a superhero and his opponents as comic-book villains. The videos quickly go viral on social media and capture the attention of major media outlets, all now tuned in to this race.
Pratt’s appeals and policy proposals on homelessness and handling the city’s long-standing drug addiction epidemic have garnered growing attention and support. Supporters from non-traditional backgrounds are coming out to support his positions. His opponents are focusing on his complete lack of government experience as a huge red flag.
Sitting City Councilperson Nithya Raman is in the race as a legitimate third option, but her numbers have declined steadily with Pratt’s rise. Most now see this as a two-person race between Pratt, the maverick outsider, and Bass, the institutionally-backed incumbent. The latter currently holds the advantage, but traders continue to adjust positions in response to polling releases and Pratt’s ongoing in-person and media appearances.
Mayoral Election Odds Snapshot on Kalshi
| Candidate | Win Probability | Change Trend |
|---|---|---|
| Karen Bass | 69% | ▲1 |
| Spencer Pratt | 26% | ▼1 |
| Nithya Raman | 7.3% | Stable |
Karen Bass Maintains Strong Incumbent Position Amid Celebrity Surge
Karen Bass holds a commanding lead in most scenarios, trading around 69%. She has many built-in advantages over Pratt, including being the incumbent, backed by most of the Democratic establishment, in a heavily Democratic city (which voted 70% for Kamala Harris in the 2024 Presidential election). She has support from the local progressive media and the entrenched political establishment. Los Angeles has not elected a Republican mayor in 25 years.
Recent polling shows Bass leading, but anything but certain in this L.A. Times report. She and her team are citing her experience in the position and point to the gains she’s made toward her original 2022 campaign promises, even if they are rather small to date. She claims to be on the right track and just needing more time. “Don’t change horses midstream” is an old political slogan she seems to be employing heavily. Also, Pratt is a total unknown with no experience in running a city. These are the themes her speeches and ads are repeating.
Debate Moments Drive Volatility in Election Betting
During multiple mayoral debates, with unusually high Los Angeles voter interest, candidates clashed over approaches to homelessness, public safety, and recovery efforts.
Pratt pressed aggressively on policy failures, creating memorable, meme-able moments that shook perspectives on trading platforms and caused huge upticks in social media discussion. Odds fluctuated as viewers processed the performances and the fact that Pratt had clearly elevated himself into a serious contender.
Pratt came out of the brief debate cycle the clear winner in terms of an uptick in movement, though not yet with any nominal polling leads.
Over $20 million in total volume underscores how this race is captivating attention beyond traditional circles. There’s Pratt’s celebrity status, plus highly viral social media videos made by both him and his supporters. And now the story has gained traction as a national news item, much like last year’s New York City mayor’s race, albeit for different underlying reasons.
Although Bass leads fairly comfortably in many contracts, as seen in Polymarket’s first-round markets, Pratt’s momentum keeps second place competitive, which could easily force a runoff between just these two candidates in November.

Looking Ahead to Primary Election
While the official primary day is June 2 in this race, California uses universal mail-in ballots, meaning that everybody receives a live ballot in the mail four weeks before election day and can return it by mail any time up until election day. It’s becoming a far more common method of voting, so a good number of votes will be submitted before election day.
Also, in this jungle primary, if no candidate receives a majority of the votes, the top two finishers will have a runoff in the General Election in November. Multiple variables to consider before a mayor is declared and prediction market contracts are resolved.
