Why Are Spencer Pratt's Los Angeles Mayoral Odds Declining on Prediction Markets?

One of the most popular political prediction markets currently trading on Kalshi involves former reality television personality Spencer Pratt and his bid for Los Angeles mayor. While Pratt's candidacy generated significant media attention throughout the campaign, traders have become increasingly skeptical about his chances following Tuesday's primary election.

As of Thursday afternoon, Kalshi traders are pricing Pratt at roughly 9% to win the Los Angeles mayoral race, well behind incumbent Karen Bass at 68% and City Councilmember Nithya Raman at 22%.

The timing of the move is noteworthy. Los Angeles voters headed to the polls on Tuesday, and while vote counting remains ongoing, prediction markets are already reacting to incoming election results. With more than $59 million in trading volume flowing through the market, the decline isn't simply random volatility. Traders are digesting real vote totals and adjusting probabilities as additional ballots are processed.

Spencer Pratt's Mayoral Odds Have Fallen Into Single Digits on Prediction Markets

At one point, Pratt's candidacy benefited from a wave of publicity and social media momentum. As a well-known television personality with a substantial online following, some traders initially viewed him as a potential disruptor capable of capitalizing on voter frustration with traditional politicians.

However, the race entered a new phase once ballots began being counted.

Before Tuesday's primary, traders were largely relying on campaign narratives, polling data, fundraising reports, and public sentiment. Now the market is receiving actual election returns. As a result, Kalshi participants are placing much greater weight on vote totals than speculation, helping explain why Pratt's odds have slipped into single digits while Bass and Raman have emerged as the clear frontrunners.

Current pricing implies:

• Karen Bass: 68%
• Nithya Raman: 22%
• Spencer Pratt: 9%

In prediction market terms, that means traders currently believe Pratt faces a difficult path to victory as the remaining ballots are counted.

Why Predictions Are Moving Away From Spencer Pratt

Markets Are Reacting to Election Results, Not Headlines

The biggest factor behind Pratt's declining odds is likely the simple fact that vote counting is now underway.

Prediction markets don't wait for official certification. Instead, traders attempt to forecast the final outcome using incoming election returns, remaining ballot estimates, geographic voting patterns, and historical counting trends.

As more votes have been reported since Tuesday's primary, market participants appear increasingly convinced that the eventual winner is more likely to be Karen Bass or Nithya Raman. That belief has pushed capital toward those candidates while driving Pratt's probability lower.

For traders, actual votes are typically far more predictive than media attention, celebrity status, or social media engagement, making the ongoing count one of the most important drivers of market movement this week.
