Everything, everything, everything is bad about the prediction markets companies - Kalshi, Polymarket, etc.
They fuel corruption, gambling addiction, insider trading, people taking different actions in order to make money, and this shows they also just lie rampantly in advertising.

A question for today:
Are we Gambling Away our Souls?
https://www.scu.edu/ethics-spotlight/the-ethics-of-prediction-markets/are-we-gambling-away-our-souls/
Deirdre M. Frontczak, Ph.D. of the Markkula Center for Applied Ethics has some thoughts.

Before we embrace prediction markets as harmless fun or even a socially beneficial trend, we might pause to raise a deeper question: What habits are we learning, and fostering, in betting on our collective future? And what kind of people do these markets train us to become?
I'm logging an open spread of 2,845 bps on the outcome NOT Mark Baisley in the 2026 Colorado Republican gubernatorial primary. Kalshi prices the NO side at 99.45¢; PredictIt sits at 71¢. Net edge after estimated fees runs to 1,835 bps. Live on Eyewall: https://eyewallmarkets.com/event/2026_colorado_republican_governor_primary

Prediction Market Philosophers Got What They Wanted. They’re Not Happy About It
"But while journalists betting on events they cover is a pretty obvious no-no, other ethical considerations aren’t as cut-and-dried. Should newsrooms, for instance, be making deals with #PredictionMarkets to integrate their data into their sites (...)? If they do, how might it affect the way reporters at those companies cover these markets? Are the odds worth covering?"

Prediction Markets are moving beyond just taking individuals' "bets" and are attempting to woo institutions such as hedge funds and brokerages to execute big-ticket "trading" like hedging against specific business risks. https://www.nytimes.com/2026/06/17/business/dealbook/hedging-prediction-markets-kalshi.html?unlocked_article_code=1.rFA.L6RD.G_CozRXwosjn&smid=url-share
