AI financing drives record U.S. convertible bond sales

The AI build-out is changing who gets the work on Wall Street. As issuers rush to fund data centers, compute and power, the convertible bond has become the financing instrument that sits between equity, debt and technology banking, and Goldman Sachs is increasingly positioned around that overlap.

U.S. convertible issuance reached about $34 billion in the first four months of 2026, more than double the same stretch a year earlier, according to Reuters. Roughly half of this year’s supply has been tied in some way to AI, and the market is on pace to beat the prior full-year U.S. record of more than $120 billion. That is not just a capital markets milestone. It is a sign that the financing burden of AI is getting large enough to reshape the mix of mandates across Goldman’s equity capital markets, debt capital markets, syndicate and technology coverage teams.

Companies are choosing converts because they want money for growth without locking themselves into a heavy fixed-coupon structure, and they still want investors to share in the upside if the AI story keeps working. For issuers, that trade-off matters. A convertible can be cheaper than straight equity and less punishing than pure debt when spending is still ramping. For bankers, it creates more complicated conversations about dilution, cost of capital and optionality, which rewards people who can speak both credit and equity in the same pitch.

Goldman’s own research shows why the market is leaning this way. Goldman Sachs Research has estimated that aggregate AI capital investment could total about $7.6 trillion from 2026 through 2031 across compute, data centers and power. The firm has also said estimates of $4 trillion to $8 trillion of total capital investment over the next five years have featured prominently in market commentary. On Goldman’s view, that scale of spending is exactly why capital markets are innovating to build the “AI factories of tomorrow.”

That shift has direct implications inside the bank. Goldman’s financing platform already covers equity, equity-linked and equity derivatives transactions, including convertible bonds. As more AI issuers look for hybrid financing rather than a simple IPO or a straight bond, the bankers closest to ECM and DCM execution become more central, as do syndicate desks that can place the paper and technology coverage teams that understand the client story. In December 2025, Reuters reported that Goldman reshaped its TMT investment banking group with an eye toward digital infrastructure and AI deals, creating new teams and reinforcing that this is now a strategic lane, not a side project.

The timing matters because investors are getting choosier. Goldman Sachs Research has said buyers have become more selective about AI stocks and have rotated away from some AI infrastructure companies where capex is debt-funded. That leaves converts in a sweet spot for the moment: they can bridge enthusiasm for AI growth with a more cautious funding market, while widening the fee pool for the bankers who can structure the trade.
