OG.com: The Newest Major Player in California Prediction Markets
OG launched on February 3, 2026 — the most significant new prediction market entrant since Kalshi. Backed by Crypto.com's CFTC-regulated exchange (CDNA) and built from the ground up as a social trading experience, OG is trying to be what prediction markets have been missing: a platform that actually feels fun. It's available in all 50 states except New York — including California.
What Makes OG Different from Kalshi
1. Parlays (Combo Trades)
OG is the only major prediction market platform offering traditional parlay-style contracts. You can combine multiple event contract positions into a single multi-leg trade with amplified payouts. This is a massive differentiator for sports bettors transitioning from Kalshi, who are used to same-game parlays. Note: parlays are available only on team-level markets (game winner, spread, total). Player prop parlays are not yet supported.
2. Social Layer — Live Chat & Leaderboards
Every OG event page includes a live community chat where traders discuss outcomes in real time. Leaderboards rank traders by volume, net profit, and win rate — creating a competitive social experience that Kalshi's more austere financial interface doesn't offer.
3. The Largest Welcome Bonus in Prediction Markets
OG's current bonus: 100% profit boost on winning trades, capped at $20/day, for 5 consecutive days — up to $100 total. No other prediction market platform offers this level of new-user value.

OG vs. Kalshi: California Comparison
| Feature | OG | Kalshi |
|---|---|---|
| California sports | Full coverage | Full coverage |
| Parlays | Team-level | RFQ system (less flexible) |
| Social/chat features | Live chat, leaderboards | Financial-only interface |
| Wildfire markets | Not available | Seasonal |
| California politics | Available | Deeper liquidity |
| Welcome bonus | Up to $100 | $10 |
| Liquidity | Building — thinner than Kalshi | Deepest in US |
| Limit orders | Not supported | Full order book |
The verdict: OG is the best choice if you want parlays, a social community, and the biggest new-user bonus. Kalshi remains the better choice for serious trading depth, wildfire markets, and precise order execution. Many California traders will want both.
OG's Upcoming Features to Watch
OG is planning to become the first prediction market platform to offer margin trading on prediction contracts, pending CFTC certification. This would allow California traders to amplify their positions — a feature that doesn't exist anywhere in the regulated US prediction market space yet.
