The Damning Evidence

AG Brown highlighted a particularly telling Kalshi advertisement:

One person texts another: "I found a way to bet on the NFL even though we live in Washington."

Brown's interpretation: Kalshi acknowledges it's skirting state law and chose to break it anyway.

What Is Kalshi?

Kalshi is a federally regulated prediction market where users can bet on outcomes of political events, economic indicators, sports, and more. It was approved by the CFTC in 2020 but has faced increasing scrutiny.

The Legal Question

The core dispute: Are prediction markets gambling or financial instruments?

Why It Matters

What's Next

Multiple states are likely to follow with their own actions. The federal courts will eventually need to resolve the tension between CFTC authority and state gambling laws.
