Is Polymarket legal in the US?

Polymarket operates offshore and does not block US IP addresses for most markets. However, it is not regulated in the US and previously settled with the CFTC in 2022 for $1.4 million for operating without proper registration. US users can access it, but there is regulatory risk. For US users who want legal certainty, Kalshi is the CFTC-regulated alternative. The legal status of prediction markets in the US continues to evolve as regulators and courts weigh in.
