Two closely watched events next week could determine whether the U.S. stock market can sustain its AI-driven advance: Nvidia’s second-quarter earnings report and Federal Reserve Chair Kevin Warsh’s appearance at the Jackson Hole symposium. With long-term Treasury yields rising sharply and the S&P 500 already retreating from its record, investors are increasingly focused on whether strong AI demand can offset renewed pressure from interest rates and financing costs.

Rising Treasury Yields Put the Rally Under Pressure

The latest move in bond markets has complicated an otherwise resilient equity environment. The 30-year Treasury yield climbed to its highest level since 2007, increasing borrowing costs for households and businesses while placing greater pressure on technology companies whose valuations depend heavily on future earnings.

The S&P 500 is down for the week and roughly 2% below its record high, while the Philadelphia Semiconductor Index has fallen about 5%. The weakness illustrates a critical tension in the current market: investors remain enthusiastic about AI’s long-term potential, but the cost of financing the infrastructure behind that growth is becoming increasingly important.

Nvidia Earnings Become a Test of the AI Investment Cycle

Nvidia’s earnings report on August 26 is therefore more than another quarterly financial update. The company has become a central indicator for the broader AI ecosystem because its accelerators underpin much of the computing capacity being built by technology companies and governments.

The scale of investment surrounding AI highlights the stakes. Nvidia recently worked with six major financial institutions on financing platforms targeting more than $500 billion for AI infrastructure. That enormous capital requirement means stronger-than-expected Nvidia results could reinforce confidence that demand is sufficient to justify the spending cycle. Conversely, any indication of slowing demand, supply constraints or weaker profitability could amplify concerns that expectations have moved too far ahead of fundamentals.

Jackson Hole Could Redefine Rate Expectations

Investors will also scrutinize Warsh’s appearance at Jackson Hole from August 27 to 29. It will be his first appearance at the symposium since becoming Fed chair in May 2026, giving markets an important opportunity to assess how he intends to communicate monetary policy.

Warsh has moved away from conventional forward guidance, emphasizing a greater reliance on incoming economic data. Markets are currently pricing a 35% probability of a September rate hike and a 66% probability by December. Upcoming inflation and economic-growth data could therefore materially alter those expectations before policymakers gather in Wyoming.

The Market Must Reconcile AI Optimism With Monetary Risk

The central challenge for investors is that the two events are closely connected. Nvidia can demonstrate that AI demand remains powerful, but higher interest rates can simultaneously increase the cost of building data centers and reduce the present value investors assign to future technology earnings.

For now, the market is being forced to reassess the balance between exceptional corporate growth and a less supportive monetary environment. Nvidia’s results could determine whether the AI narrative retains its momentum, while Jackson Hole could establish whether rising yields represent a temporary adjustment or a more persistent constraint on equities. The coming week may therefore provide an important test of whether the market’s strongest pillars can withstand a more demanding financial backdrop.
