I would love to see a graph of the total amount of money sloshing around in prediction markets in 2021, 2020, 2019, etc. stretching back as far as we have data. I'm wondering whether there is a trend and if so what the growth rate is. My Google-fu is failing me so I'm asking here in case anyone else knows.
Thanks! Gosh, it's disappointing to learn that prediction markets wax and wane in popularity over time instead of steadily exponentially increasing as I had assumed. (I'm thinking about the 'world events' kind, not the sports or stock market kind) This makes me pessimistic that they'll ever get big enough to raise the sanity waterline.
