Linera Markets has launched a testnet for its new prediction market platform, focusing on ultra-short duration markets that resolve in minutes. The platform allows users to trade the price direction of Bitcoin (BTC), Ethereum (ETH), and Solana (SOL) in rolling rounds of 1, 3, and 5 minutes, operating 24/7. This innovative approach aims to provide rapid market resolution compared to traditional longer-duration markets. The company has successfully raised $12 million in funding from prominent investors including a16z, MH Ventures, and Tribe Capital. Currently, the platform is in the waitlist stage, with actual trading not yet live. Users are encouraged to register early to gain access when the markets officially launch, as future activity will involve real capital deployment rather than testnet points farming.
