Prediction Markets

GRID's Prediction Markets aggregate discovery, trading, and portfolio tracking for binary markets across Kalshi and Polymarket.

Pulse: High‑density event browser with venue/liquidity/category filters, and per‑column search.
Live: Real‑time movers and activity.
Trading: Full workstation for a single event (selector, charts, orderbook/trades panel, Order Ticket).
Portfolio: Positions, value, and PnL.
Trades: Order history and soon analytics (coming soon).

GRID uses Privy Session Signers and Trusted Execution Environments (TEEs) to ensure your transactions are fast and secure:

Wallet protection: Your wallet's private keys are stored in Privy's TEEs, secure enclaves that are strictly isolated and not stored in complete form anywhere. They're only temporarily reconstructed when needed for transactions.
Session Signers: When you trade, GRID uses Privy Session Signers to authorize transactions server-side with specific policies that restrict what actions can be performed. This means your wallet never directly handles raw transaction data.
No key extraction: Private keys never leave the secure environment, ensuring that even if an attacker compromised your device or network connection, they cannot steal your keys or drain your wallet.

This architecture lets you trade with confidence—your assets are protected by industry-leading security infrastructure.

Use the subheader to switch between Pulse, Live, Trading, Portfolio, and Trades. The "My Portfolio" button is always available from discovery views.
From Pulse, filter by venue, liquidity/volume, and category; trade inline or open the full Trading view.

Insufficient balance: Add USDC, then reopen the Order Ticket. Max uses your current available balance.
Order not submitting: Check your connection and wallet status, then try again.

If your region isn’t supported by Polymarket or Kalshi under their terms of service, you won’t be able to trade.
