alt Hacker NewsIf it's the case that prediction market traders were trying to front-run the market outcomes, the prediction markets should put the fix on their end by locking down trading before a market closes with some time buffer to prevent this.

That's assuming the prediction markets all play fair and by the same rules. If Polymarket were to do that, its competition could choose not to. Since these exchanges are not tied to any one country (or jurisdiction), its users would jump ship. Because the users don't care.
See also stock market trading, where companies would go to great lengths to shave nanoseconds off of getting information and putting in trades. Now apply this min/maxing to worldwide, unregulated and anonymous.
This is what tech libertarians / cryptobros want.

Why should that be necessary?
You can unilaterally stop trading 'before a market closes with some time buffer to prevent this.' No need for centralised action.
