Noma is a prediction market platform that brings together markets from Polymarket, Kalshi, and other providers into a single interface. You get zero trading fees, gasless execution, best-price routing across venues, and a public identity that tracks your predictions. See Why Noma? for the full picture.
Polymarket and Kalshi are individual prediction market platforms. Noma aggregates both (and more) into one interface — so you see every market, get the best price across venues, and never pay trading fees or gas. On top of that, noma adds a social and identity layer (Pulses, leaderboards, Noma ID, Funds) that doesn’t exist on any single platform. See the comparison table.
Prediction markets let you buy Yes or No shares on future events. Share prices range from $0.01 to $0.99 and reflect the market’s implied probability — a $0.65 Yes share means the market implies a 65% chance. When a market resolves, winning shares pay out $1.00 and losing shares pay $0.00. See How Prediction Markets Work for a detailed explanation.
Crypto (BTC, ETH, SOL, XRP), equities (AAPL, NVDA, MSFT, GOOGL, AMZN, TSLA, META), and commodities (Gold, Silver). New assets are added regularly based on community demand. See Supported Assets for the full list.
Noma charges zero trading fees on every trade, on every venue. Gas fees on Polygon are also covered by noma — you never need to hold MATIC. You only pay the bid-ask spread set by the market. Note that some providers charge their own taker fees on select market types (e.g., Polymarket charges taker fees on certain crypto and sports markets) — these are provider fees, not noma fees.
Noma covers all transaction fees on both Polygon and Solana. When you place a trade, you sign a message and noma’s relayer submits the transaction on-chain and pays the gas. This applies to trading, order cancellation, wallet setup, and payout redemption. You only need USDC.e (Polygon) or USDC (Solana) to trade — nothing else. See Wallet Setup for details.
Click Sign In and choose from wallet (MetaMask, Phantom, etc.), email, Twitter, or Discord. Noma creates a secure, non-custodial wallet for you automatically — no seed phrases, no browser extensions, no friction.
Click the Deposit button on the dashboard. For Polymarket markets, deposit USDC.e to your Trading Safe on Polygon. For Kalshi markets, deposit USDC on Solana. You can buy crypto directly with a card via the built-in Coinbase Onramp, or use Blink to connect your browser wallet and bridge funds automatically. See Account Funding for the full walkthrough.
Your Noma ID is your unique identity on the platform — it replaces your wallet address on leaderboards, Pulses, Funds, and badges. Claiming one gives you a public profile at noma.xyz/id, a permanent +0.05x reward multiplier, and the Noma ID badge. See Noma ID.
Pulses are social groups where you and your friends pin markets, see each other’s positions, and compete on a group leaderboard. Private Pulses are invite-only; public Pulses are open to anyone. See Pulses.
Attest is noma’s upcoming permissionless market creation system. It will allow anyone to propose, fund, and trade custom prediction markets. Coming soon.
Funds are permissionless prediction market pools where a manager trades on behalf of depositors. Use one solo to build a public, on-chain track record — or pool capital with friends. All trades are transparent. See Funds for details and risk disclosures.
No. Noma is fully non-custodial. Your wallet keys are managed by Privy and never leave your device. Your Trading Safe is a smart contract only you control. Noma cannot access, move, or freeze your funds.
Not for Polymarket markets — you can trade immediately after signing in. KYC (via Proof) is only required for Kalshi markets, because Kalshi is a CFTC-regulated exchange. Without KYC, you can still browse all markets from all providers — you just can’t place orders on Kalshi-sourced markets. See Providers.
Yes. Noma is fully non-custodial — your wallet keys are managed by Privy and never leave your device. Your trading funds sit in a Gnosis Safe smart contract that only you can authorize. Noma cannot access, move, or freeze your funds. All trades settle on-chain on Polygon and are verifiable on Polygonscan. See Security for details on the architecture.
Withdrawals are handled directly from your Trading Safe (Polygon) or Solana wallet. You can withdraw your full balance at any time — noma never locks your funds. On Polygon, withdrawals are sent as USDC.e to any wallet address you specify.
A prediction market platform lets you trade on future events by buying Yes or No shares. Noma combines markets from multiple providers (like Polymarket and Kalshi) into a single interface — so instead of checking multiple apps and managing multiple wallets, you see every market in one place, compare prices across venues, and trade wherever the best price is. Noma also adds a social and identity layer on top.
Polymarket is a single prediction market platform. Noma aggregates Polymarket, Kalshi, and other providers into one interface — so you see every market, get best-price routing across venues, and pay zero trading fees. Noma also adds features that don’t exist on Polymarket: Noma ID (public identity), Pulses (social trading groups), Funds (managed prediction pools), leaderboards, badges, and reward multipliers. If you already trade on Polymarket, noma connects to the same orderbook — same markets, same liquidity — but adds an identity and social layer on top. See the full comparison table.
