Prediction markets don't uniquely enable it, but they make it far more effective and easy.
Insider trading is illegal. And for trades that aren't technically insider trading, often having some information ahead of time isn't as useful as it seems. Markets are known to react unpredictably to news; sometimes they move the opposite way from what you'd think, especially over the mid-long term, and there are many other influences on the price.
With a prediction market though, if you know what'll happen in the world, you know exactly what you'll win in the market.

Only in some markets and in some jurisdictions and some of the time.
Eg until fairly recently 'insider trading' in commodities wasn't anything you were punished for in the US.
