SpaceX’s $40B Off-Book Chip Debt Snags on AI Credit Turmoil

SpaceX’s “efforts to finalize a $40 billion off-balance-sheet debt structure for its artificial intelligence buildout have been roiled by recent market turmoil that’s driven up sector-wide borrowing costs and complicated price talks,” Bloomberg reported on 23 October 2026, citing people familiar with the matter.

The biggest piece is the junior one. Per Bloomberg’s report, as relayed by Investing.com on 23 October, the deal would involve three tranches of privately placed bonds, including “a subordinated portion estimated at $25 billion to $30 billion.” Subordinated debt is repaid after the other pieces if things go wrong. Earlier discussions placed its yield “around the mid-8% range,” and “worsening market conditions have prompted renewed pricing negotiations.”

What Bloomberg Reported

• The structure. The deal “would finance purchases of Nvidia chips through a special purpose vehicle (SPV), allowing SpaceX to keep the borrowing off its balance sheet and protect its investment-grade credit ratings,” Investing.com wrote, citing Bloomberg. A special purpose vehicle is a separate company set up to hold the chips and the debt.
• The lenders. Goldman Sachs is leading discussions with investors headed by Apollo Global Management, according to the report. Apollo-backed Atlas SP is expected to manage the vehicle, and Pacific Investment Management Co. is also considering taking part.
• The tranches. A subordinated portion estimated at $25 billion to $30 billion; other tranches would total approximately $10 billion and up to $5 billion, according to Bloomberg.
• The price. Earlier talks put the subordinated yield around the mid-8% range; recent credit-market volatility “has complicated negotiations over borrowing costs,” the relay says.
• The precedent. The structure follows an earlier arrangement involving xAI that failed to get its intended accounting treatment. SpaceX “subsequently recognised approximately $13 billion in debt after auditors determined the arrangement did not qualify as a completed sale-leaseback transaction,” per the relay.

What Changed Since 22 October

A day earlier, Semafor reported that the lowest-rated portion was expected to carry about 8.3% and that a safer chip-backed piece was likely to price around 7.75%, with the debt expected to be finalised sometime next week. Bloomberg’s report adds the size of each tranche, the managers and a possible third investor, and says pricing talks have reopened. The table lists each report’s figures as published; they were not reconciled by the outlets.

Sources: Semafor, 22 October 2026, as covered in our earlier piece; Bloomberg, 23 October 2026, via its post on X and Investing.com’s report on it. All figures come from people familiar with the deal.

The Junior Slice, by Our Arithmetic

By our arithmetic, a subordinated tranche of $25 billion to $30 billion is 62.5% to 75% of the $40 billion headline. The three tranche figures as reported add up to $40 billion at the low end and $45 billion at the top of the ranges, so the shares are approximate. Bloomberg did not give the yield talk for the other two tranches in the text we read.

Why SpaceX Wants It Off the Balance Sheet

The relay ties the structure to SpaceX’s credit ratings: borrowing held inside the vehicle stays off SpaceX’s own books. It says SpaceX’s third-quarter results “showed its AI business turning profitable for the first time,” that its Memphis data centres have increasingly earned revenue by supplying computing capacity to outside AI developers and large technology companies, and that executives have indicated more borrowing will be needed while keeping investment-grade ratings.

Connecting the Coverage

Our Semafor piece reported on 22 October that the deal was being finalised at about 8.3% for the lowest-rated portion and around 7.75% for a chip-backed piece, more than 1 percentage point above where SpaceX’s current bonds trade, according to Semafor.

Our CoreWeave piece covered Bloomberg’s 23 October report that a $2.3 billion loan Blackstone led for CoreWeave in 2023 became a blueprint for chip-backed debt now on track to become a trillion-dollar market.

Our markets piece covered how the 22 October AI selloff reached bonds and credit, with Bloomberg reporting on 23 October corporate bond yield premiums globally of up to 129 basis points, their widest since May 2025. Our daily briefing of 23 October grouped these stories under how the AI build-out is paid for.

What’s new: the size of the junior tranche, the names managing and weighing the deal, and Bloomberg’s report that pricing talks have reopened as borrowing costs rose.

The Structural Read

As we read it, the structure is the story: Bloomberg says the vehicle keeps the borrowing off SpaceX’s balance sheet to protect its investment-grade ratings, so the price lenders demand sits inside the vehicle.

As we read it, the timing matters: Semafor reported on 22 October that the debt was expected to be finalised sometime next week, and a day later Bloomberg reported renewed pricing negotiations.

As we read it, the precedent explains the care over accounting: per the relay, SpaceX recognised approximately $13 billion in debt after auditors ruled on an earlier xAI arrangement.

Three Implications

FOR LENDERS TO AI BUILDERS Per Bloomberg, Goldman Sachs is leading talks with investors headed by Apollo, with Atlas SP expected to manage the vehicle and Pacific Investment Management Co. considering taking part.

FOR READERS OF AI DEBT FIGURES Semafor gave about 8.3% for the lowest-rated portion; Bloomberg gave the mid-8% range for the subordinated portion in earlier talks. The two outlets did not reconcile their figures.

FOR SPACEX’S CREDIT RATINGS The relay says executives have indicated more borrowing will be needed while keeping investment-grade ratings.

The Business Engineer Lens

This story maps onto the Business Engineer framework The AI Capex Map & The State of AI Hyperscalers.

The framework describes its subject as “How the money flows, where it cracks, what it buys, who can absorb it”.

As we read it, SpaceX’s vehicle is a case of where the money flows and who absorbs it: the subordinated buyers take the first loss, and Bloomberg reports their price is being renegotiated. The framework was published in May 2026 and does not discuss this deal.

What Is Not Established

The figures come from people familiar with the matter, and the debt has not been finalised. We read Bloomberg’s post on X and Investing.com’s report on Bloomberg’s article, not Bloomberg’s full text, so any new yield level, the timing and any comment from SpaceX, Goldman Sachs, Apollo or Pacific Investment Management Co. are not in what we read. Atlas SP’s role and Pacific Investment Management Co.’s participation are described as expected and under consideration.

The Bottom Line

Bloomberg reports that SpaceX’s $40 billion off-balance-sheet chip debt has been roiled by market turmoil that raised borrowing costs. A subordinated tranche estimated at $25 billion to $30 billion, earlier discussed at a yield around the mid-8% range, is back in price talks, according to people familiar with the matter.
