Notable organizations disclosed ~2,500 high- and critical-severity CVEs in July 2026, about 5× the pre-Mythos monthly record. Epoch AI's updated breakdown of vulnerability disclosures following Anthropic's Project Glasswing.

Notable organizations disclosed ~1,300 high- and critical-severity CVEs in June 2026, roughly 3.5× the pre-Mythos monthly record. Epoch AI's breakdown of vulnerability disclosures following Anthropic's Project Glasswing.

Since January 2026, the most capable open-weight models have lagged frontier closed models by an average of four months, or 8 ECI points.

We estimated trends in global inference capacity and found that token demand appears to be growing much faster than supply.

Anthropic and OpenAI generate roughly $14M and $6.5M in revenue per employee — higher than any other tech company in the Forbes Global 2000. Continued rapid growth in this metric at tens of billions in annualized revenue is unusual, and could reflect productivity gains from AI adoption.

Amazon, Google, Meta, Microsoft, and Oracle collectively hold an estimated 71% of the world's cumulative AI compute as of Q4 2025, up from 63% in Q1 2024.

We estimate Google is the largest single owner of AI compute, holding about one quarter of global cumulative capacity as of Q4 2025, primarily from its own custom TPU chips.

As of Q4 2025, memory bandwidth across global AI chips has reached roughly 70 million terabytes per second, enough to pass all data stored on the internet into memory in under an hour.

Anthropic's annualized revenue has been growing at 10× per year since reaching $1B, outpacing OpenAI's growth of 3.4× per year. Anthropic will pass OpenAI by mid-2026 if these trends continue. However, Anthropic's growth may be slowing—since July 2025 it has only grown at a rate of 7× per year.

Across three AI companies where we can make estimates, compute is the dominant expense: R&D and inference compute together make up 54% to 62% of costs. Despite AI labs offering some of the highest salaries in tech, spending on staff accounts for less than 25% of total spending.
