How much was invested in generative AI startups in total in 2024, and how does that compare to 2023?

Global generative AI funding reached between $45-56 billion in 2024, representing a 92% increase from 2023's $29.1 billion, with the US alone capturing $97 billion in AI startup funding across all categories.

The 2024 funding levels represent 80-92% growth from 2023, demonstrating sustained momentum in AI investment despite broader venture capital market challenges. When including all AI categories beyond just generative AI, total global funding exceeded $100 billion, with generative AI comprising roughly half of all AI investment activity.

The US captured $97 billion in AI startup funding, representing 46.4% of all US venture capital activity and nearly doubling from previous years. This concentration reflects both the strength of US AI talent and the concentration of major investors in Silicon Valley and other US tech hubs.

The number of generative AI deals increased significantly to 885 completed transactions globally, indicating both larger average deal sizes and broader investor participation across the ecosystem. Early-stage deals represented 74% of all AI transactions, showing investors' focus on identifying the next generation of AI leaders.

What's the total capital raised by generative AI startups so far in 2025, and are we seeing a slowdown or acceleration?

Early 2025 data shows continued acceleration in generative AI funding, with multiple billion-dollar rounds already completed in the first quarter, including OpenAI's reported $40 billion funding round at a $300 billion valuation in March 2025.

Investment analysts expect AI to capture 45% of all venture capital funding in 2025, building significantly on 2024's momentum where AI represented 46.4% of US venture activity. Big Tech companies have committed over $320 billion combined for AI investments specifically in 2025, indicating sustained capital availability.

The pace of mega-rounds appears to be accelerating rather than slowing, with investors increasingly comfortable writing larger checks for proven AI companies. Late-stage deal sizes surged from $48 million average in 2023 to $327 million in 2024, reflecting the capital-intensive nature of AI development and scaling.

Market observers note that while deal count may stabilize, deal sizes continue growing as successful AI companies require substantial capital for compute infrastructure, talent acquisition, and global expansion. The trend suggests consolidation around fewer, better-funded AI leaders rather than a broad slowdown in investment activity.

What terms or conditions are common in funding rounds for generative AI companies—such as equity percentages, SAFEs, or milestone-based tranches?

Early-stage AI companies command significant valuation premiums, with median early-stage valuations reaching $25 million in 2024, substantially higher than traditional tech startups due to perceived AI potential and competitive investor demand.

SAFE notes remain popular for early-stage AI funding, offering founder-friendly terms without interest rates or maturity dates. Many AI startups use SAFEs with valuation caps to manage rapid growth expectations while maintaining flexibility for future rounds.

Late-stage AI companies increasingly negotiate milestone-based tranches, particularly for infrastructure-heavy startups that need to demonstrate technical capabilities or customer adoption metrics before accessing full funding amounts. These structures help investors manage risk while supporting ambitious AI development timelines.

Equity percentages for early-stage rounds typically range from 15-25% for Series A rounds, though hot AI startups with proven traction command more favorable terms. Late-stage rounds often involve single-digit equity percentages given the massive valuations, with investors focusing more on strategic value than traditional ownership targets.
