The wave of AI infrastructure financing is competing with US bonds for long-term capital, and market concerns are driving up interest rate pressure
Comparing news, AI infrastructure investment is becoming a new variable in the US bond market. As tech giants expand the construction of data centers, chips, and computing power, AI companies' demand for financing grew rapidly, and they began to compete with the US government for capital from core bond buyers such as insurance companies, pensions, and long-term asset management institutions.
According to the data, as of August, the issuance of US investment-grade corporate bonds reached about 1.7 trillion US dollars, a record high for the same period. According to Goldman Sachs data, the four major US technology companies have issued more than 170 billion US dollars in bonds since this year, which is more than the full year of 2025. Meanwhile, Broadcom is seeking chip and infrastructure financing for AI companies such as Anthropic, and the potential debt may be close to $100 billion.
Market institutions pointed out that AI brought not only an increase in the supply of US bonds, but also a long-term expansion of supply in the entire bond market. When the government and technology companies simultaneously increase long-term financing needs, and the long-term capital pool is limited, the market may require higher returns to attract buyers. St. Louis Federal Reserve Chairman Mussalem said earlier that capital competition is forming between the US government's financing needs and AI infrastructure construction.
Recently, the US bond market continued to be under pressure. The yield on US 30-year Treasury bonds once rose to 5.34%, a record high since 2007, and the 10-year US bond yield rose to 4.7%. The high interest rate environment is likely to further raise corporate financing costs and influence market pricing for AI companies through valuation discount rates.
Meanwhile, US consumption data showed signs of weakness. Walmart's stock price fell about 9% in a single day, the biggest drop since 2022. The reason was that its same-store sales growth rate fell to its lowest level in six years, falling short of market expectations, indicating that consumer spending is slowing down.
Against the backdrop of slowing economic growth and ongoing inflationary pressure, the Federal Reserve's policy faces a dilemma. The US Treasury recently expanded the scale of long-term US bond repurchases, raising the maximum single repurchase limit for 10-20- and 20-year US bonds from $2 billion to at least $4 billion. The market believes that the move is more of a signal. It has relieved the pressure on yield in the short term, but it has not changed the long-term supply and demand conflict.
Analysts believe that future market attention will focus on US fiscal financing needs, AI capital expenditure expansion, and long-term interest rate trends. If long-term US bond yields continue to rise, the market may rediscuss policy tools such as yield curve control (YCC) or quantitative easing (QE).
