Premu.xyz: The Decentralized Polymarket Alternative – User Curated Prediction Markets Anyone Can Launch
Stockholm, Sweden, May 26th, 2026, Chainwire
A new on-chain venue for prediction markets goes live today — no KYC, no disputed markets and no centralized gatekeeper – and anyone can list a market and earn from it’s creation.
Premu, a decentralized prediction-market platform, today announced the public launch of premu.xyz, bringing wallet-native, fully on-chain prediction markets to Ethereum and Arbitrum. The platform combines the breadth of mainstream event markets — politics, sports, crypto, and world news — with a high-frequency “fast market” engine that resolves five-minute BTC, ETH, and SOL up/down outcomes around the clock. From day one, Premu is positioned as a direct, credibly-neutral alternative to centralized incumbents like Polymarket and Kalshi.
Built differently from Polymarket and Kalshi
The two largest prediction-market venues in the world today both operate on a custodial, permissioned trust model. Polymarket requires geofencing and a Polygon-bridged USDC balance held in a Magic-link smart-contract wallet whose recovery is tied to email; Kalshi is a CFTC-regulated U.S. derivatives exchange that requires full KYC, social security number collection, and bank account linkage before any user can place a single contract. Both venues maintain unilateral control over who can list a market, which markets get resolved, and how quickly a withdrawal clears. Premu was built to replace every one of those frictions:
- No KYC, no email, no account creation. Users can connect a self-custodial wallet — MetaMask, Coinbase Wallet, or any WalletConnect-compatible app — sign one message, and trade. There is no identity verification, no document upload, no waiting list, and no geographic block enforced at the protocol layer.
- Instant on-chain settlement in USDC. Every deposit, trade, and withdrawal settles directly against Premu’s audited vault contracts on Ethereum and Arbitrum mainnet. Funds are never held in an operator-controlled omnibus account, never bridged through a custodial sidechain, and never subject to multi-day clearing windows or discretionary holds. A user can withdraw at any time without operator approval — the smart contract is the only counterparty.
- Permissionless market creation, with creator revenue share. Any wallet can launch a binary market on any question by posting a 250 USDC creator bond. Of that bond, 200 USDC seeds a Hanson logarithmic market-scoring-rule (LMSR) subsidy that bootstraps two-sided liquidity from the very first trade, 25 USDC covers the platform listing fee, and 25 USDC is a slashable performance bond that protects traders from spam or bad-faith markets. Creators earn an ongoing share of every dollar of fee revenue generated by markets they list — paid into a transparent on-chain ledger and claimable at any time. On Polymarket and Kalshi, the venue captures 100 percent of fee revenue and end-users have no path to listing their own markets at all.
- Fees as low as 0.10 percent. Premu’s maker-taker schedule starts at 0.10 percent — among the lowest in the prediction-market category — and steps down further as lifetime volume grows. Kalshi’s fee model can exceed 7 percent of expected value on small contracts; Polymarket’s trader-fees-plus-relayer-overhead stack typically lands materially higher than Premu’s posted rate.
A Trading Experience Built for Retail, Priced for Professionals
For users who prefer a familiar onboarding flow, Premu also offers a one-click sign-in path through email or Google. These accounts are automatically provisioned with a dedicated on-chain wallet whose private key is encrypted at rest, giving non-crypto-native users the same on-chain settlement guarantees without the friction of seed-phrase management. Whichever path a user takes, every trade settles on Ethereum or Arbitrum mainnet in USDC.
Premu’s homepage surfaces a continuously updated mix of trending, breaking, and high-volume markets, while a “Fast Markets” rail runs short-duration BTC, ETH, SOL, BNB, XRP, DOGE, and HYPE up/down contracts that resolve every few minutes against live spot prices. These synthetic contracts are priced using a transparent volatility-and-drift model derived from a rolling seven-day realized-volatility estimate, with the assumed annual volatility and prior return frozen at market creation and published on-chain so any participant can independently verify the quoted odds.
Mainnet From Day One, With on-chain Proof
Premu’s vault contracts are live on Ethereum mainnet and on Arbitrum. Both contracts implement the ERC-2612 permit standard, so deposits can be authorized with a single signature — no separate approval transaction, no wasted gas. Withdrawals are subject to a short on-chain maturity window and can be executed by the user at any time, eliminating the multi-day waits and discretionary holds that characterize centralized prediction venues.
The platform’s full feature set — including a public leaderboard ranked on realized profit and loss, shareable position tickets, a real-time activity ticker, in-app comments and reactions, and a live support channel is available immediately at premu.xyz.
