Nvidia shares fell after the board launched a CEO investigation, while U.S. Treasury yields posted their biggest weekly jump in 19 months amid uncertainty.

Nvidia shares fell on Monday after the company's board announced an investigation into CEO Jensen Huang and signaled that his future with the firm is under review.

Nvidia board actions

The board's move came amid a broader market rally, but the news pushed the chipmaker's stock lower. Analysts said the investigation could affect investor confidence in the short term.

Bond market reaction

U.S. Treasury yields rose to their biggest weekly gain in 19 months as traders prepared for possible Federal Reserve rate hikes. The surge reflected heightened expectations that the central bank may tighten policy later this year.

Anthropic IPO plans

Artificial‑intelligence startup Anthropic disclosed plans to pursue an initial public offering that could value the company at $1.4 trillion. The filing marks one of the largest tech IPO ambitions in recent history.

Investors are watching the AI sector closely after several high‑profile listings this year. Anthropic's valuation target places it among the most valuable private firms seeking public capital.

Energy prices have continued to fall, adding pressure to commodity‑related equities. Market participants noted that lower oil and gas costs are easing inflation concerns but also reducing revenue prospects for energy producers.

Overall, the mixed signals from technology, bond and commodity markets created a volatile trading day. Traders said the combination of corporate investigations, rate‑rise expectations and a looming mega‑IPO kept investors on edge.

Market analysts will monitor how Nvidia's board resolves the CEO investigation, whether bond yields maintain their upward trajectory, and if Anthropic can attract enough demand to meet its $1.4 trillion valuation goal.
