Barclays: U.S. Convertible Bond Issuance on Track to Hit Record High
0xBroomberg
U.S. convertible bond issuance has hit $57 billion year-to-date — an all-time high for the period — and Barclays expects the full year to blow past 2025's $120 billion record, as AI companies turn volatile stock prices into near-free financing.
What is a convertible bond, and why are AI companies rushing to issue them?
A convertible bond — a low-coupon debt instrument that gives the holder the right to swap it for stock at a preset price — is essentially trading "future upside in the stock" for "cheap interest today."
This means → the more a stock swings, the more valuable that conversion option becomes to investors, and the more willing they are to accept zero coupon — letting the issuer borrow almost for free.
RBC BlueBay portfolio manager Zain Jaffer put it plainly: "Issuing a convertible is essentially monetizing volatility." In plain terms = the wild price swings that make AI stocks risky are being repackaged as a financing advantage.
How cheap? Look at CoreWeave.
On April 10, CoreWeave sold two tranches: $3.5 billion in convertibles at 1.75% coupon, and — just one day earlier — $3.5 billion in senior notes at 9.75%.
This means → same company, one day apart, and the convertible's interest cost was less than one-fifth of the plain bond's.
Akamai went further — it raised $3.5 billion last month at zero coupon. ON Semiconductor (market cap ~$48 billion) also priced $1.3 billion at zero coupon, with a conversion price above the initial marketing range.
In plain terms = these companies borrowed billions and pay no interest at all — the only cost is potentially issuing more shares if the stock soars.
Who is issuing? Not the cash-rich tech giants.
Barclays' Krishna noted that hyperscale cloud providers (Amazon, Microsoft, Google) are not major issuers — they generate enough cash flow on their own.
The real issuers cluster in core AI infrastructure and second- or third-derivative AI beneficiaries — companies growing fast but still cash-flow-negative.
This reflects a long-standing pattern: the convertible market has always been the financing channel for growth-stage companies. AI simply turned up the volume.
Who is buying? What are hedge funds "arbitraging"?
The dominant buyers are convertible-arbitrage hedge funds, a strategy that has expanded rapidly in recent years.
In plain terms = these funds buy the convertible and short the stock simultaneously, capturing mispricing in volatility — they don't bet on direction, they bet on volatility itself.
BofA Americas ECM co-head Eric Coghlin summed it up: "Investors are willing to forgo higher coupons in exchange for the value of the conversion option and upside potential."
How do issuers protect themselves from excessive dilution?
Goldman Sachs' Michael Voris noted that conversion clauses are sometimes set to trigger only when the stock trades 75% to 100% above the issue price.
This means → even if investors eventually convert, the stock has nearly doubled — dilution hits only after shareholders have already profited handsomely, softening the blow.
Full-year outlook: how long can the $120 billion record stand?
Barclays U.S. equity strategy head Venu Krishna said the current pace points to 2026 issuance "meaningfully" surpassing last year's $120 billion record.
This reflects a bigger structural trend: as long as AI stocks maintain high valuations and high volatility, convertibles remain the cheapest financing tool available — the market structurally incentivizes more issuance.
In plain terms = the hotter AI gets and the more stocks swing, the wider this funding pipeline becomes. Breaking the record isn't a surprise — it's a mechanical outcome.
