The AI industry has increasingly opted for convertible bonds over traditional equity financing. In the first four months of 2026 alone, U.S. convertible bond issuance reached approximately $34 billion. This figure is more than twice the volume recorded during the same timeframe in the previous year, with nearly half of these transactions linked to artificial intelligence companies.
Why are convertible bonds becoming a preferred choice? Convertible bonds offer a mix of debt and equity characteristics. They function as debt instruments with interest payments to investors, but also grant the option to convert into shares at a specified price. This structure allows companies to borrow funds at lower interest rates, appealing to investors who may forgo higher yields in exchange for potential equity gains. Some AI companies have even managed to secure financing with interest rates as low as 0%, meaning investors are willing to buy in despite the absence of immediate returns.
Convertible bonds also provide a strategic advantage for companies looking to raise significant capital without diluting existing shareholders right away. Unlike traditional stock offerings that increase the number of shares available immediately, convertible bonds only result in dilution if the stock price exceeds the conversion price. This creates a unique opportunity for companies; should their business perform well, bondholders may convert their holdings into equity, effectively reducing the firm’s debt obligations.
A notable example of this trend is CoreWeave, which completed a staggering $4 billion issuance, characterized by individual tranches valued between $2 billion and $3 billion and a coupon rate around 1.75%. On a broader level, initiatives from major players like Alphabet and Amazon fueled a record $121 billion in hyperscaler bond issuance in 2025, quadrupling the average annual figures for comparable firms over the prior five years. Amazon even set a new benchmark by pricing a €14.5 billion euro-denominated deal in March 2026.
Investors should approach these 0% coupon securities with caution. While they represent a compelling opportunity for capital appreciation, the risk lies in the potential of deteriorating stock prices. Should the underlying equity falter, investors are left with a bond that yields no income and may depreciate in value.
With $34 billion in convertible issuances already logged for the year, market saturation could become a consideration. An oversupply without matching demand may necessitate adjustments by issuers to retain investor interest, possibly by raising coupon rates or lowering premiums on conversion.
