Final take

Should you choose Kalshi or OG?

For US-based traders, Kalshi is the obvious starting point: OG is not legally available in the United States. Kalshi is the default choice for US users who want regulated exposure to event contracts. The breadth of markets, the quality of the apps and the regulatory standing make it the strongest all-around platform for most American traders.
