Two to four listings side by side, from what each product's own pages say and the earlier Kairos listing.
Earlier-listing fields are what the Kairos catalogue said at the time, and website metadata can describe a publisher rather than the product. Neither confirms who runs a service, its current price or its regulatory status. Download this comparison as CSV
| 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. | Amplifi offers a Polymarket trading interface and publishes margin, liquidation and API documentation. Its checked markets page states that leverage is currently halted; users can open spot positions, close existing positions and withdraw. That operating notice qualifies the homepage’s leverage advertising. |

| Latest sourced pricing | Gate’s Event Market help article, dated 6 May 2026, lists a 0.8% platform charge on both maker and taker transactions, plus applicable Polymarket protocol charges. Market parameters and the actual order quote can change. This schedule should not be applied automatically to Gate’s other event-contract or DEX products. | The fee documentation adds an Amplifi charge to any Polymarket charge, on opening and voluntary closing. Its price-dependent formula uses published rate parameters of 5% for taker fills and 2% for resting fills; those parameters are not flat percentages of trade notional. Withdrawals carry a stated $0.20 USDC charge. Borrowing and liquidation charges are separate. |
| Product distinction | The provider describes centralised account access, a separate crypto event-contract product and a wallet-based DEX route. | Not established |
