Just to play devil’s advocate, I have found prediction markets genuinely useful despite never placing a bet.

In 2024 all of my social media feed was convinced the US election was going to go the other way. I have left wing politics and accordingly the algorithm wraps me in a bubble. It was all videos of empty trump rallies and Kamala hype. Polymarket was the main counter signal I had that the election wasn’t going to go the way I hoped.

Similarly when the room temperature super-conductor hype was happening in 2023, the prediction market for it being real never went above 25%. It’s extremely useful to be able to look at that as a layman and go “ok this probably isn’t real”.
