CoreWeave’s Debt Balloon Outpaces Earnings Growth
CoreWeave’s soaring interest expenses highlight the risk of rapid debt-fueled growth, with little immediate profit relief in sight.
CoreWeave’s Q2 interest expense of $640 million—a jump of 2.4 times from a year ago—shows how quickly piling on debt can backfire. Despite refinancing that cut their borrowing costs, their sheer debt load of $35 billion overwhelms any benefit. The company’s guidance for Q3 indicates interest expenses might exceed adjusted operating income by a wide margin, a troubling sign that profits aren’t catching up to their borrowing. South African investors should note this dynamic as a cautionary tale when evaluating companies, especially in sectors reliant on heavy capital spending, like our resource-heavy or infrastructure plays. The rand’s recent weakness versus the dollar (USD/ZAR) raises the local cost of funding foreign debt, adding an extra layer of pressure for any SA company expanding through dollar-denominated borrowing. CoreWeave’s risk is clear: sustaining growth is tricky when debt servicing outstrips earnings. Yet, if AI infrastructure demand keeps exploding, some argue the company might turn things around. this is just our opinion and not financial advice
Avoid CoreWeave and similar highly leveraged tech plays for now given rising interest burdens and weak near-term profitability. In South Africa, keep an eye on USD/ZAR, as rand weakness will exacerbate foreign debt costs for local firms. Favor financially sound banks like Standard Bank or Capitec instead, which benefit from improving credit quality amid rising rates.

- AI sector demand accelerates faster than expected, boosting profitability
- Rand strengthens sharply, easing foreign debt burdens on locals
6/10
CoreWeave's interest expense surged to $640 million in Q2 2026, more than double the $267 million from a year earlier, driven by a debt balance that grew to $35 billion. While the company reduced its weighted average cost of debt by 300 basis points through refinancing, the rapid expansion of borrowing outpaced these savings. With Q3 guidance suggesting interest expenses of $860-940 million against only $200-260 million in adjusted operating income, the gap between debt servicing costs and profitability is widening significantly.
