Tech giants Meta Platforms, Alphabet, and Amazon are expected to report earnings later this month, a window that may determine the direction of the broader market through year-end. Following a 0.4% decline in the S&P 500 during September, investors are closely monitoring these three companies to assess whether artificial intelligence spending remains sustainable amid rising inflation and geopolitical tensions in Iran.

According to FactSet Insight, the tech sector currently has 44 companies delivering positive earnings-per-share guidance for the third quarter, significantly higher than the five-year industry average of approximately 23. This data suggests that investor expectations ahead of these reports will be pivotal in shaping market sentiment.

Meta Platforms has transitioned from a social media company to a major AI player through heavy investment in data centers and large language models. The company recently launched Muse, a personal AI agent powered by its own Spark models. Press reports indicate that Muse surpassed 5 million downloads faster than competitors ChatGPT and Claude. While this product may not immediately drive significant revenue, it represents a key step toward AI monetization. Meta’s stock rose last month as investors recognized this shift. The company’s spending forecast for the year remains stable at $130 billion to $145 billion, and it aims to release new products in the coming year. Upcoming reports will focus on progress in these areas.

Alphabet, owner of Google Cloud, benefits from customer demand for cloud infrastructure to run AI workloads. In the most recent quarter, Google Cloud revenue soared 82% to $24 billion, driven by AI demand. Alphabet also develops its own large language models, with its AI assistant Gemini reaching 1 billion monthly users in August. This milestone makes Gemini the company’s fastest-growing product ever. Investors are eager to hear about demand strength and capital expenditure guidance during Alphabet’s upcoming earnings report, as concerns over high infrastructure spending levels persist.

Amazon competes in the same cloud space with Amazon Web Services, which is the global cloud leader. AWS offers a variety of AI products, including custom Graviton central processing units and Trainium AI chips. These products have seen increased demand from cost-conscious customers seeking quality at reasonable prices. In the recent quarter, Amazon’s custom chip business reached an annual revenue run rate of more than $25 billion. The company has stated that the AI boom could help AWS become a trillion-dollar business one day. Continuity in AWS’s revenue growth could help Amazon finish the year positively and support broader S&P 500 performance.
