Stock market gains are being fueled by expectations for hefty returns on the money being spent on artificial intelligence. Just how big could those returns turn out to be? Morgan Stanley analyst Stephen Byrd summed up the numbers. "Our analysis suggests S&P 500 companies could accrue annual net benefits totaling some $920 billion," he wrote.

That isn't chump change. Total S&P 500 pretax net income over the past 12 months, according to Bloomberg, was $2.5 trillion. An extra $920 billion could boost operating profit margins by six percentage points to over 22%, Barron's calculations suggest. After-tax net income could rise by some 40%.

Creation of AI value, says Byrd, combines cost-cutting and new revenue. There's a risk of job loss, but higher productivity typically leads to more employment in other areas. Capital outlays by Alphabet, Microsoft, Meta Platforms, and Amazon.com, much of it for AI, could reach some $340 billion in 2025, up 50% from 2024, and then climb 20% higher in 2026. From 2024 to 2026, the four may spend almost $1 trillion.

Of course, benefits won't happen all at once. And companies wouldn't keep all of the gains; some would be passed along to consumers. Still, Morgan Stanley estimates that AI could be worth $13 trillion to $16 trillion in S&P 500 stock market value. With the S&P's market cap now approaching $60 trillion, that implies an increase of 22% to 27%. That's more than just trickle-down.
