SpaceX and Broadcom Advance Major Debt Sales as AI Issuers Increase Volume Despite Higher Yields

Corporate borrowers in the AI sector issued more than $120 billion in bonds through September 2026, exceeding the same period in 2025. Market data show average yields on new tech debt climbed roughly 40 basis points year-over-year, yet primary market volumes expanded rather than contracted. SpaceX filed for a multi-billion dollar placement while Broadcom indicated a follow-on offering, both timed after the Federal Reserve held the policy rate at 4.25-4.50 percent.

Standard corporate response to rising borrowing costs has been to defer issuance and draw on existing liquidity. AI issuers have inverted this pattern because revenue growth from data-center contracts and hardware sales continues to outpace incremental interest expense. Primary documents from recent earnings calls record management statements that prioritize capacity expansion over near-term cost minimization.

Investor pricing of the new paper reflects two offsetting calculations: demand for exposure to AI cash-flow streams remains strong, while covenants and security packages have tightened relative to 2023-2024 deals. Secondary-market spreads on comparable names have widened only modestly, indicating that buyers continue to accept higher absolute yields in exchange for sector-specific growth optionality.

Next quarter issuance calendars already list additional filings from other semiconductor and infrastructure names. If 10-year Treasury yields remain above 4.25 percent into December, total AI-related debt supply could test $180 billion for the full year, a level that would require sustained absorption capacity from pension and insurance accounts.
