TLDR
- Kalshi and Polymarket are seeking $20 billion valuations as prediction markets experience a gold rush of investor interest
- Legal uncertainty around sports event contracts is making some investors nervous, with the issue likely headed to the Supreme Court
- Donald Trump Jr.’s involvement with both Kalshi and Polymarket raises concerns about what happens when the Trump administration ends
- Democrats are favored at 56% to win the 2028 presidential election, which could shift the regulatory landscape against prediction markets
- The flood of new companies entering the space draws comparisons to the post-PASPA sports betting boom, where most operators eventually failed
The prediction market industry is in the middle of a gold rush, but not everyone is convinced the boom will last.
Kalshi and Polymarket, the two biggest names in the space, are pitching investors on valuations of $20 billion each. At the same time, major sports betting and daily fantasy sports companies are pivoting toward prediction markets.
A wave of aspiring exchanges are also applying for approval from the Commodity Futures Trading Commission. The CFTC is the federal agency that regulates these platforms.
But despite all the excitement, some investors are starting to raise red flags. The core concern is that these massive valuations depend heavily on the platforms’ ability to offer sports event contracts.
The legality of those contracts is far from settled. The issue appears headed for the Supreme Court, and recent courtroom momentum has not favored the prediction market side.
Davis Catlin, managing partner of Discerning Capital, told Gambling Insider that the legal uncertainty gives him pause.
“I think there is very good legal standing for prediction markets as a financial product and marketplace,” Catlin said. “But the question really comes down to the sports side.”
Trump Connection Raises Long-Term Concerns
President Trump’s administration has been friendly to prediction markets. His appointee Mike Selig has signaled that the CFTC will continue to support sports-based contracts under his leadership.
Trump’s son, Donald Trump Jr., serves as a strategic advisor to Kalshi and is an investor in Polymarket. That connection has benefited the industry in the short term.
But it also creates risk. Trump’s second term ends in January 2029. According to odds on both Kalshi and Polymarket, Democrats are favored at 56% to win the White House in 2028.
Catlin said the Trump family’s deep ties to both platforms could become a problem if the political winds shift.
“I just really worry that if the next group that comes in are Democrats, this is an easy area to go at,” he said.
There is also movement in Congress to strip sports-related contracts from prediction market platforms. Legislation could target markets related to war and terrorism as well.
Too Many Players, Not Enough Room
Even if the legal questions are resolved in the industry’s favor, there may simply be too many companies trying to get a piece of the pie.
Catlin compared the current moment to the aftermath of the Supreme Court’s 2018 PASPA decision, which legalized sports betting nationwide. That market quickly became oversaturated.
Eight years later, only two sportsbooks are dominant. A handful of others are scraping by, and many more have shut down entirely.
A similar shakeout could hit prediction markets. Some companies entering the space are building random number generators to create outcomes users can trade on. Catlin questioned whether regulators would see economic utility in that kind of product.
“Some of the things we’re seeing are really interesting, others are just sort of people who read about it in the Wall Street Journal, and they wanna build a business around it because it’s hot,” Catlin said.
He added that the current environment has “all the hallmarks of a growth pipe cycle bubble.”
Catlin’s firm does have exposure to the space. Discerning Capital’s portfolio includes Outlier, a sports betting analytics platform that syncs with prediction markets. But he said he’s been cautious about investing directly into prediction market operators given the legal and political risks.
The 90% gambling loss deduction cap introduced under the Trump administration is seen as favorable to exchanges. However, that policy could also be reversed under a future administration.
Democrats currently hold a 56% chance of winning the 2028 presidential race, according to the latest odds posted on both Kalshi and Polymarket.
