Paramount's $12.4 Billion Junk-Bond Record, Explained

Paramount is selling $12.4 billion-equivalent of junk bonds, the biggest high-yield offering on record. Junk bonds are debt from lower-rated companies that pays higher interest to offset default risk. Bloomberg reported the figure on Sept. 28, 2026.

On Sept. 24, 2026, all U.S. bond yields except the two-year note were trading above 5%. Yield is the annual return a bondholder earns. That level was reported by Reuters.

SoftBank had raised the equivalent of $11.1 billion across dollars and euros, becoming the biggest corporate junk-bond borrower, according to Bloomberg. That account is undated and therefore lower priority than the dated Sept. 28 account. On stated size, $12.4 billion-equivalent exceeds $11.1 billion-equivalent, and the later-dated account assigns the record-offering description to Paramount.

A separate financing kicked off the prior week. A group of banks led by Goldman Sachs Group Inc. kicked off the sale of a roughly $1.1 billion junk bond to finance construction of a CoreWeave-tied data center project. Bloomberg reported the launch on Sept. 21, 2026.

From 1997 to 2025, the monthly average high-yield spread was 5.23 percentage points. Spread is the extra yield over safe government bonds for taking credit risk. That average is based on the Option-Adjusted Spread of the ICE BofA US High Yield index, according to Reuters.

The broader context here is the split between spread and all-in yield. The spread measure strips out moves in base rates and special features like early repayment options to isolate pay for credit risk. Absolute yield sets the coupon, the cash cost of debt service and the refinancing math. Narrow credit pay can therefore sit alongside high coupons. Holders collect high income while taking less incremental spread per unit of credit, downgrade and liquidity risk than the long-run average would imply.

Looking at what this means for new sales, size and currency structure matter. A $12.4 billion-equivalent deal and an $11.1 billion cross-currency deal need depth across buyers, tranches and maturities. Think of tranches as slices of one large loan sold with different terms. Dollar and euro tranches reach distinct buyers with distinct mandates, benchmarks and hedging needs. Execution risk rises with size. Price discovery turns on the new-issue discount to existing bonds, relative value across the capital structure, and limits on holding too much of one name.

In my view, the concurrent $1.1 billion project deal tests a different pocket of demand than jumbo balance-sheet supply. Corporate deals focus on company debt load, free cash flow and recovery if the firm fails. Construction finance focuses on completion risk, contracts, cost overruns and when cash flow starts. Both clear through high-yield funds, CLO-adjacent capital and cross-over accounts, but the credit work does not overlap. Spreads price credit. Coupons price rates. Covenants, calls, portability and security price control.

Looking ahead, that separation will matter if rates stay above 5% while spreads stay contained. Issuers lock in high coupons for the life of non-call periods. Investors gain income but keep price risk if spreads return toward the 5.23-point historical mean. Liquidity in secondary trading, dealer balance sheets and fund flows then determine how fast any repricing moves from new issues to outstanding bonds.
