Arc is proud to join the @Kalshi ecosystem We are building a unified trading experience where anything with a price or an outcome can be traded, starting with prediction markets. Users will soon be able to trade with leverage, access live and alternative data, and build on top of continuously updated, accurate market feeds. The data flows, the trades follow.

We’ve invited the first 1,000 traders into Arc’s Private Beta to help identify bugs and give feedback. Next, we’ll start rolling out some of Arc’s unique features and gradually expand access to a wider group of traders. Reach out for an invite.
