At least 80 new tech startups achieved unicorn status in 2025 so far, driven by a surge in AI investment and broader enthusiasm for high-growth technology ventures. According to data from Crunchbase and PitchBook, the rise of AI has been a major catalyst, with many of the new unicorns operating in artificial intelligence, machine learning, and data infrastructure. However, a notable number of the new billion-dollar companies are also emerging in other sectors, including space technology, biotech, blockchain, and clean energy. Among the most prominent AI-related startups to join the ranks this year are Genspark, which builds AI agents for task automation and raised $275 million to reach a $1.25 billion valuation; Gamma, an AI visual generation platform that hit $2.1 billion; and Fireworks AI, an open-source AI infrastructure company that reached a $4 billion valuation after a $250 million funding round. Other standout AI firms include LangChain, a platform for building AI agents, valued at $1.3 billion, and Reflection, a developer of open foundation models, which reached an $8 billion valuation after a $2 billion Series B. Beyond AI, several non-AI startups have also hit unicorn status. In space, Loft Orbital, a satellite company, raised $170 million to reach a $1 billion valuation. Stoke, a sustainable rocket company, and Apex, which builds satellites using off-the-shelf parts, also joined the list. In healthcare, Thyme Care, a personalized oncology platform, and Tala Health, a virtual care company using AI, each reached $1.2 billion valuations. PsiQuantum, a quantum computing pioneer, hit $7 billion, while Reka, an AI model builder, reached $1 billion. Blockchain and decentralized platforms also saw strong momentum. Polymarket, a prediction market platform, reached a $9 billion valuation, and Kalshi, a blockchain-based trading site, hit $2 billion. Flying Tulip, a decentralized trading platform, and Decagon, a customer service AI agent company, also joined the list. Other notable new unicorns include Base, a home battery company, which reached $4 billion; Tempo, a blockchain payments firm, at $5 billion; and Thinking Machines, a new AI research company founded by OpenAI alum Mira Murati, which raised a $2 billion seed to hit a $10 billion valuation. The list continues to grow as investors pour capital into early-stage companies with strong technology, scalable business models, and clear paths to market dominance. While AI remains the dominant theme, the diversity of industries represented underscores a broad-based confidence in innovation across sectors. The list will be updated throughout the year to reflect new developments.
