| Field | Gate Prediction Market |  |
|---|---|---|
| Product overview | Gate provides prediction-market access through its exchange and wallet products. Its own product explanation distinguishes a Polymarket-connected event market from separate short-term crypto event contracts and a self-custody DEX route. Those are different products with different account and fee conditions. | Kairos combines a prediction-market terminal with developer-facing data and execution interfaces. Its homepage describes REST snapshots, WebSocket streams and aggregated order-book endpoints, including a cross-venue best-bid/offer view. Advertised routing and latency remain provider claims. |
