And gambling, same as prediction markets, has literally no positive social outcome.

Okay, but have you considered that thanks to Polymarket, society was able to intuit within mere minutes that Khamenei was most likely dead when the odds jumped to 99%?

No more need to rely on MSM or governments, it's all just math and data (odds jumped entirely based on Reuters newswire update posting a quote from an unnamed Israeli source).

And as a bonus, people lost a bunch of money "winning" that trade!
