A lack of situational awareness

While the market gawped at a $30 billion blow-up, the US long bond just broke 19 years of history.

There are market weeks when everyone crowds around one window while the weather changes behind them. Last week was one of them.

Every trading desk and group chat was consumed by Leopold Aschenbrenner and the Situational Awareness blowout. Fair enough, as a spectacle, it is hard to beat.

A former OpenAI researcher in his mid-20s, with no prior investment experience, raises $225 million in September 2024 and turns it into roughly $45 billion by early July, up 439% net in the first half of this year alone.

JPMorgan CEO Dimon says leverage in market is ‘pretty high’

Then July happens – down about 67%, prime brokers calling for collateral, and by Wednesday, 29 July, the whole public equity book sold to Citadel in a single block before the open.

Assets decreased from $45 billion to about $10 billion.

Most of that has been written to death already, and there is little new to add.

However, two things in the coverage are worth correcting.

1. The thesis wasn’t what killed him

Aschenbrenner’s thesis may well be right. The structure, however, was never going to survive finding out. Roughly four times leverage on its public portfolio, expressed as a long AI hardware and infrastructure position against short software.

Core positions appear to have fallen on the order of 30-50% through July, set against a Philadelphia Semiconductor Index down 28.6% from its 22 June peak.

The hedge was no hedge.

The software names he was short (Adobe among them) moved sharply against him, so the short book became a second source of loss rather than an offset, and the collateral behind both legs went at once.

At four times leverage, a 20% drawdown in the underlying takes 80% of your equity. There is no recovery from that, no matter how right you eventually turn out to be. While leverage may amplify returns, it also costs you time on the position.

Unfortunately, time is often exactly the one thing you need.

The profile of the book is worth a look too. Of about $13.7 billion in reported US equity and options, around 62% by notional was in put options.

That isn’t a portfolio so much as a statement of certainty.

2. On the villain question

Much has been made of Ken Griffin as the shadowy operator who engineered all of this – and we think that is, to put it plainly, nonsense.

Millennium reviewed the book and passed. Jane Street reviewed it and passed. Citadel bought the lot, every long and every short, in a single block. Absent that bid, the portfolio is zeroed out into a thin tape the following morning, at a materially worse outcome for investors.

Markets are a blood sport. Positioning this badly wrong carries a price, and whoever has the balance sheet and the nerve to catch it when nobody else will is entitled to be paid for doing so.

The accountability question, however, remains, and few seem inclined to ask it. Who wrote the cheques?

Professional allocators with fiduciary obligations and due diligence budgets committed tens of billions to somebody who had never managed money. Not managed it badly – just simply never managed it before.

Managers with 20-year records and the scar tissue to match struggle to raise a fraction of that. That says more about how capital is being allocated in 2026 than any post-mortem on the trade.

The screen nobody was watching

While all of this was unfolding, the US Federal Reserve met and held rates at 3.5% to 3.75%.

The 30-year [bond] sold off anyway, up 11 basis points on Wednesday, 29 July to 5.2% (its biggest single-day move in more than a year) before finishing at 5.28%, a level last seen in 2007.

Compared to recent market history, this isn’t a direct inflation story. Real yields account for roughly 93% of it since mid-June, which makes this a story about term premium and supply rather than inflation expectations.

Investors want to be paid more to fund the United States for 30 years, and that is a harder problem for the Fed than a breakeven problem would be.

The 2007 comparison doesn’t flatter anybody either.

Back then, the 30-year sat at 5.28% with Fed funds at 5.25%, more or less level with each other. Today the long bond is running about 150 basis points above the policy rate, which is not a curve that believes the central bank is in control of the outcome.

This is the same trade Leopold Aschenbrenner was in, viewed from the other end.

The AI buildout has turned into a fixed-income event, and it feeds straight into that supply picture.

The big five are running toward $750 billion of capex this year and something close to $1.2 trillion in 2027.

Internal cash flow stopped covering that a while ago, so they borrow: Alphabet, Amazon, Meta and Oracle issued about $194 billion through 7 July, against $108 billion across the whole of 2025.

And the market is starting to gag on it.

Of 91 hyperscaler bonds issued this year, 78 were trading above their issue yield by 28 July, and Amazon’s $25 billion deal was enough on its own to push its existing 30-year paper 20 basis points wider.

So while equities are still arguing about whether this capex will earn its cost, credit has already answered it – in basis points.

What we take from it

Being right about direction is worth nothing if your structure can’t survive the path. Aschenbrenner may well be vindicated on AI infrastructure over a decade, but he won’t be there to collect, because 4x leverage turned a drawdown into a liquidation.

Sizing a position properly buys the time for a thesis to work.

Moreover, the AI complex has commanded almost all the available attention for two years, and attention is finite. Everything outside that frame has been developing unobserved.

If there is any concluding observation to take away from here, it is this: The US long bond just printed its highest yield in 19 years, in the face of a Fed on hold, driven by real yields and supply rather than inflation expectations.

That is a repricing of the risk-free rate that sits underneath every asset on earth, including the AI trade itself.

If long yields keep grinding higher on real rates and supply, the curve will have hiked for them.
