Supported Markets
Market categories and supported exchanges
Vezta aggregates prediction markets from two leading platforms, giving you access to thousands of markets across a wide range of categories.
Source Platforms
Polymarket
The largest crypto-native prediction market. Operates on Polygon using a central limit order book (CLOB). Order placement is off-chain via the CLOB API; settlement is in USDC.e on Polygon. Custody is via a per-user Gnosis Safe (1-of-1) deployed gaslessly through Polymarket's Builder Relayer. Known for high liquidity on political and crypto markets.
Kalshi (via DFlow)
A CFTC-regulated US prediction market exchange. Vezta integrates with Kalshi through DFlow, which tokenizes Kalshi markets as SPL tokens on Solana. You trade by signing Solana transactions directly from your own wallet -- non-custodial. KYC for buying is handled once via DFlow Proof (powered by Stripe Identity, free). Strong coverage of economics, weather, sports, and finance markets.
You can filter markets by provider at any time using the provider filter in the terminal. Select "All" to see aggregated results, or narrow down to a single source.
DFlow trading is geo-restricted by compliance: the United States and ~50 additional countries cannot trade Kalshi markets through DFlow. The platform enforces this both client-side and server-side.
Market Categories
Vezta organizes markets into the following categories, available as filter tabs in the terminal:
| Category | Examples |
|---|---|
| All Markets | Everything across both platforms |
| Politics | Elections, legislation, government policy |
| Trump | Markets specifically related to Trump-related events |

Short-Duration Markets
Vezta supports rapid-cycle crypto Up/Down markets that close every 5 minutes (Polymarket) or 15 minutes (Kalshi). These have a dedicated real-time pipeline:
- New slots are auto-discovered every 15 seconds
- Polymarket prices stream over a persistent WebSocket
- Crypto spot prices (BTC/ETH/SOL/XRP) come from Binance and overlay the chart
- A custom timeframe nav generates expected clock-aligned slots so missing or thin markets are still visible
Event Groups
Related markets are grouped into events. For example, a "2028 Presidential Election" event might contain individual markets for each candidate's probability of winning, popular vote margins, and swing state outcomes. Event groups let you browse related markets together and understand the full picture.
