CalSang and Polymarket—these two prediction market platforms are really hot these days, and they’re reportedly negotiating funding with a target valuation of $20 billion. According to a WSJ report, they appear to be pursuing a sizable round of fundraising. In particular, the fact that investment amounts are changing hands in $2 billion increments suggests that interest in prediction markets has really been on the rise. It’s interesting that these two platforms have managed to reach valuations as high as this. Is the prediction market sector really growing that much these days?
