Sector Spotlight: Foundational AI — A Category of Its Own

Foundational AI startups raised $178 billion across just 24 deals in Q1 2026, compared with $88.9 billion across 66 deals in all of 2025 — a 100% year-over-year increase, according to Crunchbase. That Q1 total is also 466.9% higher than the $31.4 billion raised across 52 deals in all of 2024.

Four labs — OpenAI, Anthropic, xAI, and Waymo — captured approximately 64% of the $297B global VC total for the quarter. This level of capital concentration in a single sector, within a single quarter, is unprecedented in venture capital history.

What does this mean for founders and investors? For AI-adjacent founders, the message is clear: the infrastructure enabling AI compute — energy, chips, and data infrastructure — is now attracting its own wave of mega-investment as reported in the April 1 funding roundup. Investors who missed the model-layer wave are now positioning in the physical stack that powers it.

For LPs and fund managers, the Q1 data raises a critical question about portfolio construction: with four companies absorbing such an outsized share of global VC, how do mid-market and early-stage funds compete for deal flow and returns in a market this top-heavy?

AI seed valuations are also climbing. Among the most recent Y Combinator cohort, many startups commanded $40 million valuations — and with higher valuations comes the expectation of faster, larger outcomes, according to TechCrunch.

What to Watch Next Week

1. AI Seed Valuation Pressure: With Y Combinator cohort valuations reportedly reaching $40M at seed stage, watch for early data on whether downstream Series A investors are adjusting expectations — or walking away from deals they would have funded a year ago.

2. 25 Newly Active VC Funds: A reported 25 fresh VC funds are actively deploying capital into founders right now, per FoundEvo. As mega-funds like General Catalyst ($10B) and Spark Capital ($3B) come online, watch for their first announced deals to signal where institutional capital is flowing beyond the AI mega-labs.

3. India's AI Startup Ecosystem: Indian startups racked up $10 billion in FY26 funding with AI looming large, according to the Economic Times. As global investors hunt for the next frontier beyond the saturated US foundational AI market, India's enterprise AI and fintech sectors may see accelerating inbound capital in Q2 2026.
