Alphabet is set to face investor scrutiny over its heavy spending on AI as it prepares to report earnings. Slower revenue growth in advertising and cloud services has raised concerns, especially as competition in AI intensifies. Chinese startup DeepSeek's launch of low-cost AI models has fuelled worries about an industry price war. Alphabet's capital expenditure, estimated at$50 billion for last year, is expected to rise further in 2025 to support AI-driven search features and cloud expansion.

Google Cloud's growth is forecast to slow in the fourth quarter despite high expectations. Analysts suggest that while heavy investment continues, efficiency gains have helped maintain profits. The company's search and advertising business remains strong, with an expected 11.2% increase in revenue, though this marks a slight slowdown from the previous quarter. Competition from Amazon and TikTok continues to challenge Alphabet's dominance in search advertising.

Political advertising linked to the US presidential election may have boosted Google's revenue, following a similar trend at Meta. However, Meta's cautious outlook for the first quarter has raised concerns about broader ad market trends amid economic uncertainty. Alphabet's shares have climbed 7% this year after a strong rally in 2023, largely driven by confidence in its AI strategy.

Investors will closely watch whether Alphabet faces the same cloud business challenges as Microsoft, whose Azure growth slowed due to a shift in AI priorities. Google Cloud revenue is expected to rise by 32% in the fourth quarter, slightly down from the 35% growth seen previously but still outpacing Microsoft and Amazon. Maintaining momentum in AI while balancing cloud growth remains a key challenge for Alphabet.
