Limitless is the breakout decentralized prediction market on Coinbase's Base network, having grown past $500 million in cumulative volume. It is permissionless and no-KYC: users connect a wallet, trade, and can create their own markets, with rewards for active participation.
It is a fraction of Polymarket's size and requires a Web3 wallet, but its low cost, transparency, and rapid growth have made it one of the most-watched on-chain venues.
