What people warn about

Each mark is one comment

  • Insiders profit from private information

    Comment from 11 Apr 2026 in “’Abhorrent’: the inside story of the Polymarket gamblers betting millions on war”

    “by using insider information about the UMA cryptocurrency whales who will ultimately decide how the market settles, whether or not it matches reality.”

    Comment from 6 Jan 2026 in “A prediction market user made $436,000 betting on Maduro's downfall”

    Comment from 27 Mar 2026 in “We Haven't Seen the Worst of What Gambling and Prediction Markets Will Do”
  • Unclear or manipulable resolution rules

    “in practice it’s vulnerable to interpretation of ambiguous wording”

    “by using insider information about the UMA cryptocurrency whales who will ultimately decide how the market settles, whether or not it matches reality.”

    Comment from 13 Apr 2026 in “Nothing Ever Happens: Polymarket bot that always buys No on non-sports markets”
  • Markets can encourage real-world harm

    “Giving people an easy way to profit (i.e. incentive) to use either direct political power or indirect power via bribes is going to have massive consequences on corruption.”

    Comment from 11 Apr 2026 in “’Abhorrent’: the inside story of the Polymarket gamblers betting millions on war”
