Goldman blocks staff from bank-linked event contracts

$GS has reportedly banned employees from trading prediction market event contracts tied to the bank.
The restriction shows how quickly prediction markets are moving into areas that create compliance and conflict-of-interest concerns for major financial firms.
For Goldman, the issue is less about market size and more about reputational, regulatory, and internal-risk controls.
The bigger signal is that event contracts are becoming important enough for Wall Street firms to write specific trading rules around them.
If more banks follow, prediction market access could face tighter institutional compliance boundaries.
