Here is the number that reframes every AI funding headline you have read this year: in the first half of 2026, two companies — OpenAI and Anthropic — raised $217 billion between them, or 43% of all startup funding on the planet. Not 43% of AI funding. Of all venture funding, across every sector, everywhere.

That figure comes from Crunchbase's H1 2026 data, and the totals around it are just as stark.

A record built almost entirely on AI

Global venture funding hit $510 billion in the first half of 2026 — more than the $440 billion invested in all of 2025, in half the time. The first quarter alone drew $305 billion, the largest quarter on record; the second added $205 billion across more than 5,000 startups.

The concentration is the real story. More than 70% of global startup capital in Q2 went to AI-focused companies, up from just under half a year earlier. Anthropic raised $65 billion in a single quarter and became the most valuable private company on Crunchbase's board. The money is not spreading across a booming market; it is pooling at the top of one.

What "43% in two companies" actually means

A venture market usually works by spreading many bets across many companies, most of which fail, a few of which pay for the rest. A market where two firms absorb nearly half of all capital is not really doing that. It is closer to infrastructure financing — a small number of enormous, capital-hungry builds — than to classic startup investing.

That has knock-on effects worth watching. When this much money concentrates in a handful of model labs, the rest of the ecosystem competes for what is left, valuations for anything AI-adjacent get pulled upward by association, and the whole sector's health becomes tied to whether those few very large bets pay off. It also helps explain the eye-watering numbers further down the stack — a chip startup being repriced sixfold on a single lab's order, for instance, makes more sense when you see how much capital is chasing a seat in this particular game.

The honest caveats

Two things to hold alongside the headline. First, these are H1 figures — the January-to-June picture, not a snapshot of this week — so read them as the shape of the year so far, not a fresh event. Second, a dollar of "AI funding" is not one thing: it spans real frontier-model raises, infrastructure and chips, and a long tail of companies that added "AI" to a pitch deck. The concentration at the very top, though, is not ambiguous. Two names, 43% of everything.

Why it matters

Records get broken every year; that is not the point. The point is what the composition says about where the technology — and the risk — now sits. When a single half-year outraises an entire prior year, and two companies hold nearly half of it, the AI build-out has stopped being one story among many in venture capital. For now, it is the story.
