The big conversations

No cavalry: the bond rout settles in, and the question becomes who breaks first
The selloff that began with three hikes didn’t pause for breath. John Authers spent Monday finding a silver lining in 10-year Treasuries, Tuesday asking what breaks in the “Bondpocalypse”, and Wednesday watching the shift wash into Europe. John Stepek’s Thursday headline did the summarising: the cavalry isn’t coming. On Odd Lots, Sherwood’s Luke Kawa made the sheer speed of the moves the story; Adam Tooze’s weekend links insisted any theory of higher US rates must explain why every market is moving together, with the yen carry trade unwinding underneath; and on Prof G, Michael Green took the other side of the gloom entirely.
Where they agree
- Nobody expects a rescue: most treat the repricing as structural (Green, who calls it mechanical, is the exception), and the conversation has moved from direction to casualties — who is exposed if the long end simply stays here.
- The move is global and correlated — Europe and the yen carry trade are now part of the same story, which is what makes single-market explanations unsatisfying.
Where they split
- Green says buy: the sell-off is mechanical — index construction and passive flows — not fiscal. Authers is torn across his own week — Monday’s silver lining became Tuesday’s “what breaks?”.
- Kawa’s worry is velocity rather than level: markets and the news cycle are moving fast enough that positioning accidents get likelier. Tooze watches the yen carry unwind as the transmission channel nobody wants to price.
- Stepek’s point is the absence: whoever you think rides to the long end’s rescue — they’re not coming.

Hyperscale my debt: the AI build-out moves onto the bond market’s tab
The Unhedged podcast gave the week its title — “Hyperscale my debt!” — on the trillion-dollar borrowing binge behind the AI build-out, with the FT’s Emily Herbert on what bond issuance from the likes of Amazon and Meta is doing to corporate credit markets. Herb Greenberg’s weekly Wrap had already listed the cracks: CoreWeave running a venture arm despite its losses, Blue Owl’s planned $6.5bn data-centre REIT, Oracle’s force-majeure notice, private credit wobbling. Prof G reported investors turning against data centres outright, All-In added falling token prices to the revenue side of the ledger, and Levine’s Monday title asked where the risk goes once the banks recycle it.
Where they agree
- The financing mix has shifted from equity to debt just as money got expensive: whatever the models eventually earn, the build-out now has coupon payments to make.
- Oracle’s force-majeure notice has become the shared reference point — the first physical-world crack everyone can cite without arguing about valuation.
Where they split
- Greenberg hears a credit cycle starting — his title is “something’s gotta give”; Unhedged still frames it as an absorption question — how much paper the corporate bond market can digest before it chokes.
- Prof G reads investor patience as already gone. All-In’s worry is the other blade of the scissors: token prices falling while the debt stays fixed.
- Levine’s headline interest is the plumbing — banks moving the exposure along rather than holding it, which is either comfort or the sequel, depending on your memory of 2007.

AI & Markets4 of 37 sources on this · the float thread turns concrete
The S-1 leaks: Anthropic’s numbers get out, and the arguments get specific
Anthropic’s float stopped being a prospectus argument and became a document this week. Prof G put Paul Kedrosky on the filing — the losses, in his reading, are stunning — with IPO scholar Jay Ritter on Oura’s shelved float, and by Friday had Steve Eisman arguing that one company could break the AI boom and that Anthropic and OpenAI are “manufacturing a crisis”. The 20VC news roundtable read the same leak alongside Instinct’s $1bn raise and AMD’s purchase of World Labs; TBPN tracked Dario Amodei’s week from an SNL appearance to a private dinner at the White House; and Matt Levine asked the filing-adjacent question only he would ask: if your risk factors include the end of the world, is that securities fraud?
Where they agree
- The vocabulary changed with the filing: the argument is now about losses, burn and float mechanics rather than model quality — a spreadsheet fight, not a demo fight.
- IPO timing is slipping across the big labs, and everyone connects it to the same two forces: open-source price pressure on tokens, and a bond market that now charges real money.
Where they split
- Ritter notes that most companies that pause IPOs never go public; Eisman says the crisis talk is manufactured — and goes hunting for the single point of failure he thinks could break the whole boom.
- Levine’s angle is disclosure: an existential-risk warning is a legal instrument as much as a confession, and it sits oddly in a sales document.
- TBPN reads the Washington charm offensive as the actual strategy — on that view the S-1 is downstream of politics, not the other way round.

The agents get a balance sheet: Instinct raises at $10bn, and inattention stops paying
Last week the agents were an app-chart story; this week they got term sheets. Instinct raised $1bn at a $10bn valuation in the same week its founder, Noah Shinn, told Invest Like the Best how quickly users are trusting an agent with their money. Parag Agrawal told 20VC that agents already search the web a thousand times more than humans — and that the ads business model dies. Matt Levine turned the thesis into a trade: businesses priced on customer inattention, banks above all, are short the attention that agents supply. PensionCraft asked what happens to the subscription economy’s laziness tax when software does your cancelling, and MBI’s headline made the same bet from the other side: Muse may never need ads.
Where they agree
- The common target is inertia: deposit spreads, unused subscriptions, defaults nobody switches away from — the quiet margins that assume the customer isn’t paying attention.
- Capital has stopped waiting for proof: a $10bn valuation for Instinct prices the thesis, not the product.
Where they split
- Shinn’s evidence is that trust comes fast: three weeks in, 40% of users have shared a credit card with Instinct. Agrawal and MBI think the advertising model goes first, and soon.
- Levine’s dispersion point cuts both ways — attention is a cost as well as a weapon, and some retail-facing firms win from agent traffic even as the banks lose the float.
- PensionCraft brings it home: the household wins the laziness tax back — unless, as they note, the subscription economy reprices to survive it.

Conference season sends the bill: social care, the growth question, and first-time buyers
The promises arrived at the party conferences; the costing arrived with them. Robert Peston put the question directly to Andy Burnham’s big plans — NHS-style social care, talk of rejoining the EU — and asked whether any credible growth strategy sits underneath. Monevator noted who has historically won from buyer-support schemes — the homebuilders — and Doomberg’s warning cut underneath the lot: Britain’s real exposure this winter is energy, just as the brief changes hands in the reshuffle.
Where they agree
- Policy, not rates alone, is the active variable in UK returns now — and every source prices the conference promises against a bond market that charges for them in real time.
- Every promise is being priced against a bond market that now charges for it — credibility and cost are the same question this autumn.
Where they split
- Peston’s question is credibility — big plans with no growth strategy attached.
- Monevator plays it as an investor: Monevator notes that when the state subsidises housebuying, the builders have historically been the winners.
- Doomberg thinks housing is the wrong worry entirely: the energy system heading into winter — with a new hand on the brief — is where Britain’s downside actually lives.

Disagreement of the week
The sell-off is a buying opportunity: it is a mechanical by-product of badly built bond indices and passive flows, not a verdict on US finances — and long-duration bonds are on sale.
— our paraphrase of Michael Green on Prof G Markets, 29 September
VS
Bond yields have been rising and the cavalry isn’t coming: anyone positioned on the assumption that central banks will ride in and cap the long end is waiting for help that isn’t on its way.

Worth your time — three picks

Ramez Naam, guest post | Noahpinion | 27 September 2026 · ~15 min read, free
Naam works the numbers on recursive self-improvement and finds the loop too weak for a fast takeoff: his estimate puts the productivity gain at roughly 2–3% per unit of capability against a ~15–19% threshold for self-sustaining acceleration, with real-world lab results lagging benchmark-implied progress by an order of magnitude. Expect rapid but roughly linear progress, he argues — which, in a week when the S-1s and the bubble arguments all turn on growth curves, is the capability-side arithmetic the financing debate was missing.

In the week the bond market became everyone’s problem, a long conversation with someone who has made mispriced fixed income her entire career: Zimmerman co-founded Bracebridge (now over $12bn) in 1994 with seed money from Yale’s investment office, and here walks through hunting persistent inefficiencies across developed-market rates, structured credit and EM — plus position sizing, risk management and team building. A working manual for the regime the rest of this page is arguing about.

Joe Weisenthal & Tracy Alloway, with David Kang | Odd Lots | 2 October 2026 · 53 min listen, free
With the energy shock still working through refined products, a former Qatar Airways treasurer explains the machinery: hedging jet fuel with swaps and options, using heating oil as the traded proxy, and why some airlines end up running refinery exposure of their own. The rare energy-crisis episode that is about the plumbing rather than the forecast — and all the more useful for it.
