43% of all venture capital on Earth just went to two companies. Your AI vendor strategy just got dangerous.

$510 billion in global venture funding in H1 2026.

A record.

And 43% of it — $217 billion — went to OpenAI and Anthropic.

Strip out those two companies and the market looks like 2024. Ordinary. Uneventful.

But that is not the world you are buying in.

Here is what the concentration actually means for your enterprise:

Your AI vendor options are narrowing fast.

The capital is piling into already-proven winners. Late-stage funding rose 141% year over year in Q2. Deal counts did not meaningfully grow.

This is not a broadly healthy startup ecosystem. It is an extraordinarily narrow one.

And the public markets just started grading AI spending on attribution.

Alphabet reported a revenue beat and raised capex guidance to $195-205 billion. The stock fell 7% the next day. Free cash flow turned negative.

Meta reported revenue up 28%. Stock fell. Guidance raised to $130-145 billion in capex.

The Street stopped rewarding AI ambition. It now demands receipts.

Your board will ask the same question: which specific revenue or cost line does this investment move, and by when.

Meanwhile, Anthropic and OpenAI both filed confidential S-1s. The public disclosures will reveal gross margins, compute commitments, and customer concentration for the first time.

Those numbers will reset how the entire category is valued.

Audit your AI vendor dependencies today.

Map which providers hold equity in your vendors' suppliers and customers. Those relationships shape roadmap priorities, pricing, and who gets capacity when supply is tight.

If your AI strategy assumes abundant capital will keep flowing at this rate — stress-test the scenario where it does not.

The organizations with a clear line from AI investment to a specific outcome will survive either world.

The ones funding capability with no attribution story will not.

SIGNAL: Capital concentration at this level means enterprise AI vendor risk is now systemic. Your procurement strategy must account for equity relationships, margin disclosure coming from IPO filings, and the possibility that the funding environment shifts dramatically in H2.
