The Financial Post reports in its Friday edition that Broadcom shares slipped Thursday after a two-year forecast for artificial intelligence chip sales failed to impress investors, a sign it is still in the early stages of challenging Nvidia's dominance. A Bloomberg dispatch to the Post says that although AI-fuelled revenue is soaring, the company is seeing pressure on its gross margins, Bank of America analyst Vivek Arya said in a note. He also expressed concern about Broadcom's increasing reliance on Anthropic PBC and OpenAI as customers, since they have other chip options available, including Nvidia and Advanced Micro. Broadcom is contending with "a more competitive neighbourhood," Mr. Arya said. Investors had initially reacted positively to the company's AI chip forecast, which showed dramatic growth. Sales from that market will double to about $115-billion in fiscal 2027 and soar to $230-billion the following year, chief executive officer Hock Tan said during a conference call Wednesday (all figures U.S.). The company also is on track to top earnings of $30 a share in fiscal 2028, outpacing Wall Street estimates. Broadcom's custom AI semiconductor business has benefited from the likes of Google, OpenAI and Meta.
