How AI Demand & U.S.-Iran War Control the Stock Market

• The market is trading on two assumptions: continued AI demand and an end to the U.S.-Iran conflict.
• AI demand is the most important factor, driving the S&P 500 to new all-time highs.
• The semiconductor sector's market cap in the S&P 500 has grown from 6% (pre-ChatGPT) to over 22%.
• Despite new S&P 500 highs, there have been more 52-week lows than highs, indicating narrow market breadth.
• A significant market pullback could occur if AI demand suffers or investor sentiment towards AI spending changes.

The market is currently driven by two main assumptions: sustained AI demand and a resolution to the U.S.-Iran conflict, with AI demand being the most critical factor. The S&P 500 is reaching new highs due to AI, despite narrow market breadth, but a pullback is anticipated if AI demand falters or sentiment shifts.
