Prediction markets are getting bigger, but players and the broader gambling industry should be careful about treating that growth as proof of trust or value.
Although there is no direct state policy update for California players, the debate still matters. It centers on market integrity, regulation, and whether these products deliver meaningful public benefit.
Trading volume is rising, and so is regulatory scrutiny. Thus, whether prediction markets, like Kalshi and Polymarket, are overhyped remains an open question.
Why This Matters Beyond California
Prediction markets are a fast-growing part of the wider gambling and financial ecosystem. Certik reports trading volume rose from $15.8 billion in 2024 to $63.5 billion in 2025.
That kind of growth helps explain the rising attention from media, social channels, and regulators. But headline volume does not settle bigger questions about market operations or public interest.
This is the key point for Californians following online gambling and related markets. Rapid expansion brings more visibility, but also more questions about transparency and oversight.
The Risks Behind the Growth Numbers
Several risks could matter to both regulators and users. As per Columbia Business School researchers, wash trading has reached as much as 60% of volume at various times. Wash trading is also illegal in regulated markets.
Insider-trading concerns also apply, especially for banks with employees on these sites. Additionally, a Politico report found that Polymarket paid some online influencers through a personal account.
Taken together, those points show the debate extends beyond popularity. It is also a question of user trust in platform activity.
What the CFTC is Watching
The Commodity Futures Trading Commission (CFTC) is trying to bring prediction markets under its remit. It is also evaluating whether they serve the public interest.
CFTC Chairman Michael S. Selig said,
“The CFTC will protect the integrity of our regulated markets without standing in the way of responsible innovation.”
He added that prediction markets must fall under the agency’s “transparent, accountable, and time-tested framework” or “drift into the shadows offshore.”
For players, the biggest near-term issue is not a new market launch or product feature. The real issue is federal oversight — will it become clearer, and will it address manipulation, transparency, and user confidence?
The Bottom Line for California Players
Prediction markets are increasingly part of California’s broader conversation around online wagering, gaming-style products, and consumer protections.
Currently, the practical takeaway is simple: regulation matters more than growth rate. Questions around wash trading, insider-trading risk, and public-interest standards could shape platform trustworthiness over time.
The next thing to watch is the CFTC’s approach. If the agency moves toward a clearer framework for prediction markets, that could have broader implications for users nationwide, including California’s iGaming market.
Until then, expect the debate to stay focused on oversight, integrity, and whether market protections match their rising profile.
