Major U.S. stock indices reached record highs in mid-April 2026 despite the ongoing conflict in Iran [2, 3].

This divergence highlights a growing gap between the U.S. tech-driven economy and other global markets, suggesting that artificial intelligence spending may be insulating American investors from geopolitical shocks.

The S&P 500 rose 0.8% and broke above its previous record [2]. This growth was driven largely by strong earnings from technology giants and record-level spending on AI infrastructure [1, 2, 3]. Market analysts said that investors are increasingly optimistic that the Iran war will not cause lasting economic damage [3].

While Wall Street hit an all-time high [2], the Australian Securities Exchange did not mirror this success. The Australian share market did manage to recover from an eight-day losing streak [1]. However, individual corporate performance remained mixed in Sydney.

ANZ Group reported a half-year profit of $3.65 billion [1]. Despite this substantial profit, ANZ shares fell [1].

Investors on Wall Street appear to be betting on a potential ceasefire or a limited economic impact from the hostilities in the Middle East [3]. This sentiment contrasts with the more cautious movement seen in the ASX, where regional economic factors, and specific banking performance weighed on the indices [1].

“Wall Street hit an all-time high despite the ongoing Iran war”

The contrast between the U.S. and Australian markets suggests that the 'AI trade' has created a decoupled economic reality. While traditional markets remain sensitive to geopolitical instability and regional banking trends, the massive capital injection into AI infrastructure is currently outweighing the risks associated with the conflict in Iran for U.S. investors.
