Stockholm-based crypto firm PremiumBlock today launched a non-custodial risk hub that combines user-created prediction markets, leveraged trading, and Web3 poker — all without a centralized custodian. The platform, available now, targets users who want direct market access without waiting on approvals or withdrawal queues.
A wallet-native approach
PremiumBlock’s platform runs entirely from the user’s wallet. There’s no deposit to a central exchange, no custodial bankroll. Users create prediction markets on crypto, sports, politics, culture, macro events, and world news — then trade the outcomes. The same wallet handles deposits, withdrawals, and fund management across the hub’s three main offerings: prediction markets, crypto perpetual futures, and poker.
Baqir Hussain at PremiumBlock said the platform was built for people who want direct market access without waiting on approvals, custodians, or withdrawal queues. The non-custodial design means users keep control of their funds at all times.
User-created markets with leverage
Unlike curated prediction markets like Polymarket or Kalshi, PremiumBlock lets anyone create a market. The result is an uncurated catalog covering everything from election outcomes to meme coin price moves. Selected markets offer up to 2.5x leverage — a feature that sets the platform apart from most prediction market competitors, which typically limit leverage to 1x or don’t offer it at all.
Leverage on prediction markets is rare. PremiumBlock’s move suggests a bet that users want to amplify their exposure to event-driven bets, not just binary yes/no positions.
Perpetual futures and Web3 poker
The platform also supports crypto perpetual futures — no expiry dates, just ongoing positions. That’s standard enough on centralized exchanges, but less common in a non-custodial environment.
Then there’s the poker component. PremiumBlock’s Web3 poker offers fast deposits and instant withdrawals, all managed non-custodially. The idea: treat poker like any other risk market, with the same wallet-level bankroll control.
Expanding the prediction market category
PremiumBlock is positioning itself as a broader alternative to platforms like Polymarket and Kalshi. The focus on user-created markets with leverage, perpetual futures, and wallet-based control aims to pull in a different crowd — traders who want more than binary bets and who distrust custodians.
The launch comes as prediction markets gain mainstream attention, but most remain limited to curated outcomes and 1x payouts. PremiumBlock’s offering is riskier by design — uncurated markets can mean less liquidity and more manipulation risk. The non-custodial model also puts the burden of security squarely on the user. Still, for the audience that wants it, the platform is live now.
