Two hundred and forty billion dollars went into AI last quarter. Capital is moving faster than the moats it's funding can hold.

Capital at escape velocity

Investors deployed $300 billion globally in Q1, with 80% aimed at AI. Bezos is closing a $10 billion round for a physical AI lab that didn't exist six months ago, and Anthropic hit $30 billion in annualised revenue, overtaking OpenAI for the first time.

The shrinking moat

Kimi K2.6, an open-weight model from a Chinese lab most Western builders haven't heard of, now beats GPT-5.4 and Claude Opus 4.6 on SWE-Bench Pro. If you're building a wrapper, Elad Gil thinks your window at peak value is roughly twelve months.

Security still lags the tooling

Vercel's breach started with an employee connecting a third-party AI tool with broad OAuth permissions. Veracode's latest report shows AI-generated code passes security tests only 55% of the time, unchanged across two years of model releases.

Everyone builds now

App Store releases jumped 60% year-over-year in Q1 and 104% in April alone, likely driven by AI coding tools putting first-time developers over the finish line. Microsoft's new image model cuts costs by 41%, making another piece of the stack cheaper for solo builders.

The infrastructure gap

ChatGPT went down for 90 minutes on Sunday, and VentureBeat reports multi-agent systems still can't share reasoning context. MIT Technology Review launched a new annual list because AI alone generated too many candidates for its existing one.

The money says AI is the future; the benchmarks say today's advantages expire fast. Your differentiator is what you do with the window you have left, not which model you use.
