ed revenue of the entire generative AI industry was around $175 billion annualized run rate as of June 2026. Every other dedicated model developer (e.g. the Chinese labs, Mistral, xAI before the SpaceX acquisition) was below $1 billion/year in run rate as of late 2025 or 2026; The growth rate within 2026 may be slowing down. For example, the two labs were reportedly around $55B combined at the end of Q1, nearly doubling in the first quarter, but took around four months to double again (still a f

When looking at inference coding performance, OpenAI, Anthropic, xAI, and other frontier labs focus on three things. They look at performance per dollar versus interactivity (TPOT), TTFT (time to first token), and overall end-to-end task completion. Performance per megawatt is also important, considering that terrestrial datacenter power is a critical constraint (money is a social c

labs in adoption decisions at the frontier. To put it simply – the Chinese labs use all the time that American labs do pre-release testing to keep hillclimbing on benchmarks (SpaceXAI is likely far closer to the Chinese labs here). With the pace of progress being so fast, this is likely the largest determining factor of why Chinese labs stay at the frontier. This, so far, has been economically acceptable for the American labs, as they’ve still had massive demand for their models. As model self-i

All of these questions have an economic valence: can the leading developers capture enough value vs. their competition to sustain the frenetic infrastructure build-out? The US/China framing has additional geopolitical implications. One way closed-weight developers could capture this value is if the open- vs

pending an estimated $450bn a year on AI infrastructure. Its answer has been the EU AI Act and a capital commitment that is a rounding error by comparison. A single American site, xAI’s Colossus in Memphis, runs more than half a million GPUs. Europe has nothing remotely at that scale. The instinct to govern this technology is right, but we’re off on the ambition by orders of magnitude. It is fair to object that regulation is itself a form of power.
