questions
Is this gambling?
No. Tellmarket shows you data — it doesn’t place trades. You read prices on two platforms; what you do is up to you.
Do I need a Kalshi or Polymarket account?
Yes — to actually take a trade. Tellmarket finds the opportunity; you execute on their apps via the deep links we send.
