Across six large AI financings we covered this year, nine instruments add up to $132.3 billion, and $8.0 billion of that, about 6%, sits in the hybrid middle between debt and equity, by our arithmetic and our classification.
The rest is either debt-like (senior notes, venture bonds and a GPU finance lease) or plain equity. Within one deal, the first-loss slice paid 8.5% against 5.75% on the senior notes above it, a gap of 2.75 percentage points by our arithmetic.
Business Pill · Credit Spread
An evergreen Business Engineer explainer on credit spreads, the price lenders charge over safe debt. It teaches the general idea only and does not discuss this story.
The key insight: In six AI financings we covered, nine instruments add up to $132.3 billion, and $8.0 billion of it, about 6%, sits in hybrid instruments between debt and equity, by our arithmetic and classification. Inside the Anthropic compute vehicle, the junior first-loss tranche paid 8.5% against 5.75% on the senior notes, per Financial Times research as we reported.
A primer posted on X on 8 November by @BoringBiz_ draws the line. Credit is senior loans and high-yield bonds: “Fixed coupon; par at maturity”, “Upside capped at par + coupon”. Equity is a “Residual claim; no set return” with “Uncapped upside; board control”.
In the overlap the primer lists five hybrids, ordered from most debt-like to most equity-like: mezzanine, holdco PIK notes, convertibles, hybrid bonds and preferred equity. Mezzanine is “Sub debt behind senior loans; cash and PIK coupon”. A convertible is “Unsecured notes; low coupon plus an option on the stock”. Preferred equity sits “Behind all debt, ahead of common; no maturity”.
The primer’s own footnote applies here too: “Typical features; pricing and terms vary by company, credit quality and market conditions”.
Nine instruments from six AI financings we covered, ordered from most debt-like to most equity-like. Amounts and coupons are from Oracle, Meta, SpaceX and CoreWeave filings and releases, Financial Times research (Anthropic vehicle), IFR (Hyperion coupon) and Reuters (Nooks), as reported in our earlier pieces. The band classification and the totals are our arithmetic: $8.0 billion of $132.3 billion, about 6%, sits in the hybrid middle. The SpaceX lease and CoreWeave notes had not closed or priced in the filings cited.
What Was Posted on X
Primer on Hybrid Capital, the middle between credit and equity
This primer posted on X by @BoringBiz_ on 8 November sets out the spectrum this piece uses: credit at one end, equity at the other, and five hybrids in between, from mezzanine to preferred equity. Its own footnote says the features are typical and that pricing and terms vary by company, credit quality and market conditions.
Where the AI Deals Sit
Senior debt: Oracle’s $10 billion of notes priced in five fixed-rate series at coupons from 7.000% to 8.650%, according to its pricing term sheet. That is the plain end of the spectrum.
Lease built like debt: SpaceX’s 8-K puts its Apollo GPU lease at approximately $40 billion of principal payments over about five years. The 8-K says the lease is subject to closing conditions, and its fixed rate had not been set.
Tranched vehicle: the Anthropic compute vehicle buys TPUs and leases them to Anthropic on a 5-year term. Per Financial Times research, it is funded by $6 billion of senior A1 notes at about 1% over Treasuries, $24 billion of senior notes at 5.75% and a $4.5 billion junior first-loss tranche at 8.5%, with Apollo and Blackstone anchoring.
Equity: Blue Owl’s funds made a cash contribution of approximately $7 billion to the Hyperion venture, Meta’s release says, and Oracle sold 86,206,897 shares at $116.00 alongside its notes, about $10 billion.
Support That Is Not Capital
Some of the risk transfer never shows up as money raised. Broadcom provides a residual-value and deficiency guarantee on the roughly $30 billion of senior notes in the Anthropic vehicle, triggered only by both an Anthropic default and a resale shortfall, per FT research as we reported.
Meta provided residual value guarantees to each venture, and its 10-Q puts the maximum at $41.49 billion. Nvidia’s quarterly report lists $108.5 billion of maximum exposure under guarantees, including guarantees capped at $105 billion for an OpenAI campus in Ohio. We keep these out of the $132.3 billion total, because they are contingent support, not funding.
Update (9 Nov): a hybrid from Chinese telecom and computing supplier ZTE. ZTE, whose computing business made up 38% of revenue in the first nine months of 2026 according to the company, set a 1.70% coupon on 6 November for RMB 1 billion of “science and technology innovation renewable corporate bonds” issued on 9 November, according to its coupon announcement as reported by Guandian. Its Shenzhen Stock Exchange issuance notice capped the tranche at RMB 1 billion and set a 1.40%–2.40% coupon range, so the bonds priced 30 basis points above the bottom of the range (our arithmetic). ZTE extended that day’s bookbuilding by an hour, citing relatively sharp market moves.
The terms put it in the hybrid middle described above. The notice gives a three-year base term that ZTE may extend without limit, with the coupon resetting on extension to the benchmark rate plus the initial spread plus 300 basis points (the step-up capped at 300 basis points in total); an option to defer interest unless ZTE pays a common dividend or cuts its registered capital; repayment ranked behind ordinary debt in a liquidation; and classification as an equity instrument in ZTE’s accounts. The notice says proceeds after fees will go entirely to working capital; it does not earmark them for computing. This is the first tranche under a registration for up to RMB 8 billion of corporate bonds, and it is not part of our $132.3 billion tally of six financings.
As we read the filings and reports, AI builders are reaching for structures that keep assets or debt in separate vehicles before they reach for the hybrid middle. In our sample, $8.0 billion of $132.3 billion is hybrid, and $4.5 billion of that is the first-loss slice inside a vehicle rather than a corporate security.
The Structural Read
As we read the deals, the risk transfer mostly happens through structure, not through hybrid securities: a venture bond in Hyperion, a tranched vehicle for Anthropic and a finance lease for SpaceX.
As we read the primer next to the deals, the closest match to its hybrid list is CoreWeave’s proposed convertible, which the primer describes as unsecured notes with a low coupon plus an option on the stock.
As we read the Anthropic vehicle, its $4.5 billion junior tranche plays the role the primer gives mezzanine: subordinated to the senior notes and paid more for it.

“Unsecured notes; low coupon plus an option on the stock”
Three Implications
FOR LENDERS The Anthropic vehicle’s senior notes carry a Broadcom residual-value and deficiency guarantee, per FT research, while the junior holders take the first loss.
FOR THE COMPANIESMeta’s 10-Q puts its maximum residual value guarantee to its data center ventures at $41.49 billion, support that does not show up as money raised.
FOR SHAREHOLDERS Oracle sold 86,206,897 shares at $116.00 alongside $10 billion of notes, the only plain common-stock sale among the six financings.
The essay argues that “the capex race is no longer a corporate spending cycle” and that “It is a sovereign-scale financing problem dressed in tech-company clothing”.
As we read it, the spectrum above shows the forms that financing takes in practice: venture bonds, tranched vehicles and leases, more often than hybrid securities. The essay does not discuss these six deals.
What Is Not Established
The band classification is ours. The six financings are deals we covered, not a census of AI financing, so the 6% share describes this sample only. The amounts are summed only to size the sample. The SpaceX lease and the CoreWeave notes had not closed or priced in the filings we cite.
The Anthropic vehicle’s tranche terms come from Financial Times research as we reported in August. Nooks’s terms were not disclosed. The primer describes typical features of each instrument, not these deals.
This Week In The AI Supercycle
The Great Convergence of Capital, Power, and Geopolitics
This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
In six AI financings we covered, $8.0 billion of $132.3 billion sits in hybrid instruments, about 6% by our arithmetic and classification, and the junior tranche in the Anthropic vehicle paid 8.5% against 5.75% on the senior notes above it.
