AI venture capital, 2022–2025

AI captured 61% of all global venture capital in 2025 — about $258.7 billion of $427.1 billion deployed (OECD). After dipping from its 2021 peak, VC investment into AI firms rose roughly 109% between 2023 and 2025, recovering to record levels. AI’s share of all venture capital has climbed steadily as non-AI funding stayed flat. Corporate AI investment had already reached $252.3 billion in 2024 (Stanford HAI).

Why funding is so concentrated

Frontier-model training is extraordinarily capital-intensive, so a handful of labs absorb a disproportionate share of capital. OpenAI, Anthropic, xAI, Scale AI, and Project Prometheus each raised more than $5 billion in 2025; together they accounted for roughly one-fifth of all venture funding worldwide (Crunchbase). That concentration is one reason analysts debate whether AI investment is a durable buildout or a bubble.

Venture momentum: 2025 in review

KPMG’s Venture Pulse confirms the scale: global VC investment climbed past $500 billion in 2025, up from $391.9 billion in 2024, with Q4’25 alone reaching $138 billion — the highest quarterly total in 14 quarters — fuelled almost entirely by AI (KPMG Venture Pulse Q4 2025). In Q4’25, eight U.S. AI companies each raised $1 billion or more, including Anysphere (Cursor, $2.3B), Reflection AI ($2.0B), Lambda ($1.5B) and Crusoe ($1.4B).

The infrastructure supercycle

Beyond startup funding, the largest cloud providers are pouring record sums into data centers and compute. Combined hyperscaler capex is projected to exceed $600 billion in 2026 — roughly a 36% increase over 2025’s record levels — with the majority directed at AI infrastructure (Goldman Sachs; BloombergNEF). IDC puts AI infrastructure spending at roughly $90 billion in Q4 2025 and forecasts $487 billion for full-year 2026 (~53% growth), exceeding $1 trillion by 2029 at a ~31% CAGR (IDC). Projected 2026 capex: Amazon ~$200B, Alphabet ~$175–185B, Meta ~$115–135B, Microsoft ~$120B+, Oracle ~$50B.

The numbers in full

Capex figures are company guidance / analyst projections and span data-center spend beyond AI alone; IDC’s figures isolate AI infrastructure specifically.

Frequently asked

How much money went into AI in 2025?
AI firms captured about 61% of global venture capital in 2025 — roughly $258.7 billion of $427.1 billion deployed. KPMG puts total global VC above $500 billion for the year, with AI driving nearly all the growth. (OECD / KPMG)

What is OpenAI’s valuation?
OpenAI closed 2025 valued at approximately $500 billion, one of the most valuable private companies in the world. Anthropic was valued at about $183 billion. (Crunchbase)

How much are companies spending on AI infrastructure?
IDC forecasts AI infrastructure spending of about $487 billion in 2026 (~53% YoY growth), rising past $1 trillion by 2029. Separately, the largest hyperscalers are projected to spend $600 billion+ on total capex in 2026, much of it on AI. (IDC / Goldman Sachs)
