SignalPlus raises $50 million at a $500 million valuation

SignalPlus said it closed a $50 million Series B1 on 1 June at a $500 million post-money valuation. HashKey Capital led the round, with BlockBooster and AppWorks also participating. The Hong Kong-based company provides trading and risk-management software for institutional digital-asset derivatives. It said proceeds would support product diversification and geographic expansion.

SignalPlus reported $160 billion in platform volume in Q4 2025 and 74% quarterly compound growth in terminal volume since 2023. These are issuer-supplied metrics, not independently audited market-wide figures. The valuation indicates investor interest in trading infrastructure but does not establish that company volume or market share will keep growing.
