Venture capital is a form of private equity in which professional investors provide funding to early-stage, high-growth potential companies in exchange for an equity stake. Venture capital funds are raised from institutional investors such as pension funds, university endowments, and family offices, and are managed by general partners who source deals, lead investments, and support portfolio companies through growth. In 2025, global venture capital funding reached $425 billion across more than 24,000 companies, representing a 30% increase over 2024 and the third-highest annual total in venture history, according to Crunchbase data.
Think of a venture capital firm as a professional talent scout who bets on emerging companies before the world knows their names, and who takes an equity stake for accepting that early risk.
A venture capital fund is structured as a limited partnership. The venture capital firm, acting as general partner, manages the fund and makes all investment decisions. The investors, called limited partners, provide the capital and receive the majority of the financial returns. General partners typically contribute 1% to 2% of fund capital alongside their limited partners.
The fund earns money two ways. Management fees, typically 2% of committed capital per year, cover operating costs during the fund's life. Carried interest, typically 20% of profits above a hurdle rate, compensates the general partners for investment performance. A fund that returns $500 million on $100 million invested generates $400 million in profit, of which $80 million is the general partner's carry and $320 million returns to limited partners.
Venture capital investments follow a progression through distinct stages, each representing a different level of company maturity and risk.
Artificial intelligence captured approximately 50% of all global venture funding in 2025, reaching $211 billion, up 85% from $114 billion in 2024. Five companies alone, including OpenAI, Anthropic, Scale AI, xAI, and Project Prometheus, raised more than $5 billion each in 2025 and collectively received $84 billion, representing 20% of total global venture investment. The OECD reported that AI's share of global venture capital more than doubled from 30% in 2022 to 61% in 2025.
The U.S. maintained its dominance in this cycle, capturing 64% of global venture funding in 2025, up from 56% in 2024 and significantly above the 47% to 48% it represented from 2019 to 2023. AI infrastructure firms attracted the largest rounds, with Anthropic's $13 billion Series F in September 2025 representing the largest single venture round of the year.
Venture capital returns are driven by a small number of exceptional winners in each fund. Most venture-backed startups fail or return less than the invested capital. A fund that generates a 3x to 5x return over a 10-year fund life typically achieves that result because one or two portfolio companies delivered 20x to 100x returns that more than offset losses on the rest. This power law distribution is why portfolio construction, deal sourcing, and follow-on investment discipline matter so much in venture capital.
Exits occur through three paths: IPO, acquisition by a larger company, or secondary sale to another investor. In 2025, the IPO market reopened meaningfully, and M&A volume for venture-backed companies hit its highest level since 2021, including Google's $32 billion acquisition of cybersecurity firm Wiz as the largest M&A deal for a venture-backed company ever.
