Fast-growing AI companies need enormous amounts of capital.
But issuing ordinary debt can be expensive, while selling too much equity can dilute existing shareholders.
That is where convertible bonds come in.
AI-cloud company Nscale recently agreed to sell about $3.1 billion of convertible bonds, including $1 billion to Nvidia, as it prepares for a U.S. IPO. Nscale is growing quickly, but it also reported a $1.02 billion net loss in the first half of 2026.
Convertible bonds offer a middle ground between debt and equity.
What Is a Convertible Bond?
A convertible bond starts as normal debt.
The investor lends money to a company.
In return, the investor receives:
- interest payments
- repayment at maturity
- the option to convert the bond into shares
So the security combines:
bond protection + potential equity upside
That can make it attractive to both companies and investors.
Why Companies Use Convertible Bonds
Growth companies often prefer convertibles because they can borrow more cheaply.
Why?
Because investors are willing to accept a lower interest rate in exchange for the possibility of receiving shares later.
Imagine:
Normal bond coupon: 8%
but
Convertible bond coupon: 4% + stock conversion option
The company pays less interest today.
For a capital-intensive AI company, that can save significant cash.
What Is the Conversion Price?
The conversion price determines when the bond can effectively become equity.
Suppose a company’s stock trades at $20.
A convertible bond might allow investors to convert at $30.
If the stock stays below $30, investors may simply keep the bond.
But if the stock rises to $50, converting into shares can become attractive.
That gives investors upside if the company succeeds.
Why Investors Like Convertibles
Convertible bonds can provide a different risk-return profile from ordinary stocks.
If the company performs poorly, investors still hold debt with a claim on repayment.
If the stock performs very well, they may convert and participate in the upside.
That creates an asymmetric structure:
Downside protection from the bond
plus
Upside potential from the shares
It is not risk-free, however.
If the company runs into serious financial trouble, bondholders can still lose money.
The Main Risk for Shareholders: Dilution
Convertibles can eventually create new shares.
That means existing shareholders may own a smaller percentage of the company after conversion.
For example:
100 million existing shares
plus
20 million new shares from convertibles
means existing shareholders now own a smaller share of the business.
This is called dilution.
So convertible financing may protect cash flow today but reduce ownership per share later.
Why AI Companies Are Natural Users
AI infrastructure companies often face a difficult financing problem.
They need large amounts of money for:
- data centers
- GPUs
- power infrastructure
- networking
- cloud capacity
But many are still scaling and may not yet generate large profits.
Nscale fits that pattern. Reuters reported that its revenue jumped to $140.6 million in the first half of 2026, while losses remained above $1 billion. It also has more than $103 billion in total contracted value, highlighting both rapid growth and enormous capital needs.
Convertible bonds can therefore help fund growth without forcing the company to issue all the equity immediately.
Expected Return vs Risk
For investors, convertibles sit between bonds and stocks.
| Feature | Convertible Bond |
|---|---|
| Interest income | Yes |
| Principal repayment | Usually |
| Equity upside | Yes |
| Dilution risk | Yes |
| Credit risk | Yes |
| Stock sensitivity | Increases as shares rise |
The key question is:
Is the equity upside worth the credit and dilution risk?
For shareholders, the question is slightly different:
Does cheaper financing today create enough future value to offset dilution later?
The Bottom Line
Convertible bonds are useful because they solve a financing trade-off.
Companies get:
lower borrowing costs + delayed equity issuance
Investors get:
bond protection + potential stock upside
But shareholders must watch the conversion terms carefully.
The most important factors are:
coupon + conversion price + maturity + dilution
For fast-growing AI companies, convertibles can be a flexible way to fund expansion.
But whether they create value depends on what the company earns from the capital raised.
