I really wonder whether privacy would actually be the answer here --- prediction markets as they are now where the odds are public really shouldn't be called prediction markets, they should be called "outcome-shaping markets" because largely that is what they do, they let people shape real-world outcomes with massive amounts of liquidity. If instead these were privacy protocols where you can see how much liquidity is on a specific market, but no one can decrypt how much liquidity is on each side until the outcome executes (i.e. using threshold encryption, commit reveal, etc), you'd have a very different situation where your ability to predict in advance is what gets rewarded and there is no ability to "copy trade"
