Who is borrowing, how much, and at what price · 521 SEC-priced deals in 2026 so far plus the biggest private placements · updated

Companies are borrowing at a record pace — to buy other companies, to build AI data centers, and to refinance. This page follows the deals as they price: every bond with an SEC pricing term sheet, tranche by tranche (size, coupon, maturity, spread over government bonds), the biggest private placements that never file one, and the hyperscaler AI-capex debt in its own section. Mortgage rates, which compete with this paper for the same long-term buyers, are on the mortgage rates page.

A public deal is listed here when its term sheet or prospectus carries a special mandatory redemption clause — the issuer must buy the notes back if the takeover fails — which is how bonds that fund a deal are written. Private placements are listed when the issuer says the proceeds fund an acquisition. Target names are taken from the term sheet or the deal’s announcement; where neither names one, this page says “an acquisition.”

Rule 144A and Regulation S deals, plus convertible notes, sold to institutions: none files a pricing term sheet, so the figures are taken from the issuer’s own filing or press release (linked in each row; where the filing isn’t out yet, the row says so). This is a selection of the largest deals — not every private placement — and sizes are as priced; convertibles often close larger once the initial purchasers take their option.

Deals of at least $1 billion (or the equivalent) priced in the past year, plus every hyperscaler deal, read from the term sheet, pricing supplement or prospectus supplement the issuer filed with the SEC (the link in the last column). Spreads are over the government bond of the deal’s currency (Treasuries, Bunds, Gilts, Canadas) or, for yen deals, over swaps; floating-rate tranches pay a margin over the overnight rate instead, and capital-instrument tranches that reset their coupon show no spread. A prospectus supplement prints size, coupon and maturity but not a spread or yield, so those deals show a dash and a maturity year only.

The AI build-out: hyperscalers and their suppliers

Amazon, Alphabet, Meta, Oracle and Microsoft have borrowed more than anyone, a growing share of the AI data-center bill sits in project companies that never appear on their balance sheets, and the companies that sell the chips and servers are borrowing too. This section follows that debt on its own, and puts it next to mortgage rates. What the money buys is on the AI buildout tracker: GPU rental prices, memory chip prices and the power grid, next to the stocks of the companies that sell them.

$296.1B of AI build-out borrowing in 2026 so far (the tile at the top of the page) is the sum of:

The yield each maturity’s most recent U.S.-dollar hyperscaler deal actually priced at, taken from its SEC term sheet — the rate that issuer locked in for the life of the bond, not a live market quote. The comparison is with the most recent deal at the same maturity at least nine months earlier, so it reads as “roughly a year ago” rather than an exact anniversary. Treasury yields are the latest daily close from the Federal Reserve’s H.15 release.

Hyperscaler and supplier issuance by quarter

SEC-registered U.S.-dollar deals by issuer; the dashed layer is off-balance-sheet 144A project debt tied to a hyperscaler. The hatched layer on top is the public bonds of chip, server and data-center companies (Nvidia, Dell, AMD, Broadcom and others; listed below). Private placements are left out of the history because we only track them from 2026. Everything starts at the first hyperscaler deal we track. Euro, sterling, yen and Canadian-dollar deals are in the deals table above, not the chart.

Registered USD deals only. Microsoft has not sold a bond in this period. Suppliers are the public bonds of chip, server and data-center companies. Private placements aren’t in this table (we only track them from 2026); with them, 2026 so far is $296.1B.

New-issue spread over Treasuries

One dot per fixed-rate hyperscaler USD tranche within a year of the benchmark maturity, at the spread it priced at. Up and to the right means the same company is paying more to borrow for the same term. Triangles are the chip, server and data-center suppliers. A spread reflects the issuer’s credit quality as well as the market, so compare each company with its own earlier deals rather than with the others. Deals filed only as a prospectus supplement state no spread and aren’t plotted.

Crowding out? Mortgage spread vs issuance

Loading rate history…

Solid: 30-year fixed mortgage rate minus the 10-year Treasury yield (weekly). Dashed: the extra yield the whole U.S. investment-grade corporate bond market pays over Treasuries — an index of dollar bonds rated BBB or better across every sector (banks, utilities, industrials, tech), weighted by size, with call features adjusted out. Hyperscaler and supplier bonds are part of it, so it’s context, not an independent check. Bars (lower panel): hyperscaler issuance per month, registered plus off-balance-sheet, with the public bonds of chip, server and data-center suppliers in a second shade on top. Correlation here is context, not proof of cause.

A small share of the whole market can still be a large share of the long end.

These companies sell the chips, servers, networking gear and data-center space the build-out buys, and they count here because of who the issuer is: a bond filing doesn’t say what the proceeds fund, so some of this money may repay debt or pay for something else. U.S.-dollar public deals only. Which issuers count is our own short list — Nvidia, AMD, Broadcom, Micron, Dell, Hewlett Packard Enterprise, Super Micro, Arista, Equinix and Digital Realty. A dash means the filing is a prospectus supplement, which doesn’t state a spread.

Bond & credit market news

How to read the corporate bond tracker

When a company needs billions of dollars at once — to buy a competitor, to build data centers, to replace debt that is coming due — it usually sells bonds. A single deal is often six to ten bonds of different maturities, called tranches, sold on the same day. This page follows those deals as they price, and what they cost.

Where the data comes from

Public deals come from the pricing term sheet an issuer files with the SEC on the day a bond prices. It lists every tranche — with its size, coupon, maturity, re-offer price, yield and spread over the benchmark government bond. Issuers that file no term sheet (several large banks, for one) are read from their prospectus supplement instead, which gives size, coupon and maturity but no spread. Private placements file no term sheet, so the biggest ones are listed from the issuer’s own filing or press release, linked in each row. Off-balance-sheet deals are private 144A placements by project companies; they are identified from the issuer, matched to their bond listings, and sized from the sponsor’s pricing announcement.

Acquisition bonds

A company buying another usually raises the money before the deal closes, and bondholders want protection if it never does. So these bonds typically carry a special mandatory redemption: if the takeover fails, the company must buy the notes back, at par or slightly above. That clause is printed in the term sheet, which makes it an objective marker of a bond that funds an acquisition. It also explains why these deals can be enormous — they are sized to the purchase price, not to the company’s usual borrowing. Private placements are tagged from the issuer’s stated use of proceeds.

Private placements

Most high-yield bonds and almost all convertible notes are sold under SEC Rule 144A to large institutions, without the public registration process. That is also why they file no term sheet. This page lists a selection of the largest, with the figures taken from the issuer’s own announcement. Convertible notes pay a low coupon — sometimes zero — in exchange for the right to turn into stock, and usually close larger than they price once the banks take their option. A high-yield (or “junk”) bond is one rated below investment grade by the agencies; the tag appears only where a source states the rating.

Reading the spread

A bond’s new-issue spread is the extra yield it pays over a government bond of similar maturity at the moment it is sold, in basis points (hundredths of a percentage point). It is the cleanest measure of what investors demand to lend to a company, because it strips out the general level of interest rates. When the same issuer has to pay a wider spread for the same maturity deal after deal, investors are asking more to absorb more of its debt.

Off-balance-sheet debt

Not all of the AI build-out’s borrowing shows up as a hyperscaler bond. Increasingly a separate project company borrows to build a data center that a hyperscaler will use, and the bonds are repaid from that use. The hyperscaler’s link can be a lease (it is the tenant), a lease backstop (it guarantees a smaller tenant’s rent), or a joint venture (it co-owns the project and guarantees its value). The largest example is the $27.3 billion Beignet Investor bond that financed Meta’s Hyperion data center in Louisiana — larger than most of Meta’s own bond deals, and not on Meta’s balance sheet.

How big is it?

Against the whole U.S. bond market, hyperscaler borrowing is small: a couple of percent of all bond issuance, and under one percent of Treasury sales once short-term bills are counted. Against the corporate market it is large for a handful of companies — a high-single-digit share of all corporate bonds sold. Where it matters most is the long end: measured against the 20- and 30-year bonds the Treasury itself sells, hyperscaler bonds maturing fifteen or more years out are a meaningful fraction, because that is where they compete with the Treasury and with mortgage investors for the same insurers and pension funds.

Mortgages and crowding out

Mortgage rates are priced off mortgage-backed securities, which compete for the same long-duration fixed-income investors — insurers, pension funds, bond funds — as high-grade corporate bonds. A heavy supply of long-dated, highly rated corporate debt can widen the spread those investors demand across the board. The crowding-out chart plots the 30-year mortgage rate’s spread over the 10-year Treasury against hyperscaler issuance so the relationship can be judged directly. Many other things move mortgage spreads — rate volatility, bank demand, the Federal Reserve’s own mortgage holdings — so a correlation on this chart is context, not proof of cause. Daily rates by loan type, credit score and down payment, with a live estimate, are on the mortgage rates page.

What’s not here

The public list depends on finding each issuer’s filing, so a deal whose paperwork is laid out unusually can be missing or understated, and the private-placement table is a selection rather than every deal. Totals add up U.S.-dollar deals only; euro, sterling, yen and Canadian-dollar deals are listed in their own currency. Structured notes, asset-backed securities, bank capital instruments with no fixed maturity, and sovereign and agency borrowers are left out.

Deal terms are as priced at issue; bonds trade at different prices and spreads afterwards. Acquisition and AI labels reflect what each issuer or filing says the money is for, and off-balance-sheet coverage is limited to deals whose hyperscaler link has been publicly disclosed. This page is for information only and is not financial advice.
