    Frequently asked questions

    Is Rebet legal in the US?

    Yes. Rebet is a federally-regulated event-contract platform operating under federal commodities law. It is legal for US traders to use, just like Kalshi, Sleeper, and other regulated prediction markets.

    What makes Rebet different from Kalshi?

    Rebet is social-first. It's built around group chats, shared positions, and community discussion. Kalshi is more finance-focused — better for solo traders who want broad market coverage and quiet concentration.

    Who is Rebet best for?

    Younger sports fans, group-chat traders, users who want cross-sport social trading in one app, and casual fans who want skin in the game without the sterile feel of a trading terminal.

    Can I trade the NBA Finals on Rebet?

    Yes. Rebet covers NBA playoffs and Finals markets, including game-level and series-level contracts. Player props are available though depth varies by matchup.

    Can I trade the 2026 World Cup on Rebet?

    Yes. Rebet covers the World Cup 2026, including match-level markets, tournament winners, and group stage contracts. For the full World Cup strategy, see our World Cup 2026 guide.

    How does Rebet make money?

    Rebet charges per-contract fees on trades, typically disclosed at order entry. Fee levels are competitive with other federally-regulated prediction markets.

    Is Rebet safe to fund?

    Rebet operates under CFTC regulation, which requires customer fund segregation and federal compliance. The platform is a regulated venue. Underlying trading risk (you can lose what you deposit) applies to every prediction market.

    Should I use Rebet or Kalshi?

    Use both. Kalshi for serious positions and broad market coverage. Rebet for social, group-chat trading on sports. They complement each other well for most US traders.
