Blast Radius

Jensen Huang told Nvidia's employees on Sunday that he'd been unfaithful to his wife. By Monday's close the stock was off 4.3% and $192 billion was gone.

Most affairs have a blast radius of one kitchen table. A wife, the kids, a few colleagues who stop making eye contact. This one runs from Santa Clara to a House committee that wants him in a closed room on November 18, the day after earnings. The woman worked for a customer that bought $4.8 billion of his chips, and U.S. intelligence thinks she worked for Beijing too.

Now look at the rest of Monday's tape. The S&P closed up 2.3%. The Nasdaq, 2.7%. AMD was up 13%. If Nvidia had only kept pace with the S&P it would be worth nearly $300 billion more tonight. The market sold the man and bought everything standing next to him. Where I come from that's called idiosyncratic risk. It hurts like hell if you're holding it, and the system shrugs.

Look at how much machinery we've built to price one human. A ticker that reprices every second. A board with outside counsel by Sunday night. Congress. Analysts on TV by breakfast asking who the heir is (there isn't one, which is most of the $192 billion).

And look who paid. Jensen owns about 3.5% of Nvidia, so Monday cost him $6.8 billion. The other $185 billion came out of people who weren't in the room.

He has a kitchen table too, and it's nicer than most. Forbes puts $155 billion on it. California is a community property state, and half of that is about $78 billion, twice what MacKenzie Scott took out of Amazon. Nobody has filed anything. That's just the size of the room this went off in.

Here's what I haven't seen anyone write. The thing his chips run has a blast radius too, and it's the other kind. Anthropic's S-1 counts more than 11,900 customers paying six figures, all leaning on the same few models. When a man fails, he fails alone. When a model fails, it fails everywhere, the same way, in the same minute. Anyone who traded through 2008 remembers what correlations do in a crisis. They go to one.

We've had the preview. On August 1, 2012, Knight Capital pushed bad code into production and lost $440 million in 45 minutes. No affair, no spy, no villain. Software with authority and nobody standing next to it.

So where's the machinery for pricing that? METR spent eleven weeks inside Anthropic and found its models improving 1.9 times faster than before, with about 80% of the speedup coming from AI doing the research. Then Anthropic, which held the redaction rights, cut most of the evidence METR found most useful. Days before the roadshow. Jensen got an independent committee. The model got a redacted memo.

Jensen has no heir. The model is writing its own.

A guardrail is a promise the builder makes. A price is a verdict somebody else hands down. We have the second for every human who matters and almost nothing for the machines we're handing the keys.

The market priced the man before the opening bell. Price your machines before they price you.

$192 billion. That's what Nvidia lost Monday after Jensen Huang admitted an affair with a woman U.S. intelligence says was working for Beijing. The S&P rose 2.3% the same day. So the market can price one man's worst decision in a morning and move on. Now ask what the quote is on the model running inside eleven thousand companies at once. There isn't one. That's the blast radius nobody's pricing.

For the investor — sort your risk into two piles. Nvidia fell 4.3% while AMD rose 13%. That's key-man risk, and you can diversify it. Then count how many of your holdings run on the same one or two model vendors. If the answer is all of them, you don't own a portfolio. You own one position with a lot of logos.

For the business owner — write page two for your AI. Nvidia had no succession page for Jensen and it cost $192 billion in a day. Which model does your quoting, your support, your code? Visa just tested 22 models at shopping, and 54% of the runs that failed still bought something. Put a dollar ceiling on what any agent can do without a human signature. Today.

For the parent — teach radius before reach. Your kid's agent can send, post, buy and publish at a scale no teenager has ever had. On a new benchmark the best coding agent hit 70% of the requirements and fully finished 26% of the jobs. Looking done and being done are different things. Ask tonight: if this gets it wrong, who does it hit, and can you take it back?
