ChatGPT set off a VC rush to invest in generative AI startups; PitchBook says AI startup investments grew from $1.5B in 2020 to $5.9B+ since the start of 2022
Context & Ripple Effects
ChatGPT's release turned a niche thesis into the default venture bet. PitchBook had already counted $1.37B into generative AI across 78 deals in 2022 — nearly matching the prior five years combined — and this Reuters piece pegs the trajectory from $1.5B in 2020 to over $5.9B since early 2022. The striking part is that this happened inside a downturn: by late 2023, US venture funding had fallen almost half while generative AI deal value rose 65%, making AI the sector absorbing capital everything else lost.
What followed confirms the pattern rather than reversing it: generative AI companies drew $56B worldwide in 2024 across 885 deals, US AI-focused VC hit $65B in Q1 2025 alone — up 550% from the quarter before ChatGPT shipped — and OpenAI's $8.3B round at a $300B valuation showed the top of the market pricing years ahead of its revenue base.
First-order effects
- Generative AI startups become the one category where VCs deploy counter-cyclically, even as overall US venture funding contracts — founders in adjacent software categories now raise against an investor base whose attention and check sizes have migrated.
Second-order effects
- Capital concentrates at both ends of the funnel: seed activity stays broad ($500M across 198 angel/seed deals in H1 2024) while a handful of frontier labs absorb outsized late-stage checks, squeezing mid-stage startups between a crowded entry gate and a winner-take-most exit market.
Third-order effects
- If the pattern holds, US venture returns become structurally levered to a small set of AI positions — PitchBook's later data showing AI taking the overwhelming majority of US venture dollars alongside stalled unicorn fundraising points toward a two-track private market where non-AI companies struggle to reprice or exit.
- Geographic concentration compounds the same dynamic: non-US startups raising just $6.2B of 2024's $56B suggests the capital cycle consolidates model-building and its economics in a few US hubs, pressuring other ecosystems to fund applications rather than foundations.
The trend: Venture capital is repricing itself around generative AI as its core asset class, concentrating dollars in a handful of frontier labs while the rest of the startup market competes for what remains.
