Is AI Finally Delivering a Return on Investment
Wall Street investors are starting to ask a blunt question about artificial intelligence: is it time for the technology to enter the payback period and actually show its return on investment? The answer is not immediately clear, as AI’s contribution often remains buried in the broader earnings numbers rather than standing alone in the spotlight.
Block’s latest quarter is an early test of what happens when a financial company doesn’t simply add AI to its products but, in fact, restructures the company around it. Six months after cutting more than 40% of its workforce, Block reported 25% year-over-year gross profit growth, a record 27% adjusted operating margin, and 65% growth in adjusted diluted EPS. It also raised its full-year outlook.
Last week, I looked at Block’s Q2’26 results and how AI is increasingly shaping the way the company operates. That got me thinking about the next question. If AI is changing the operating model, how do we know when AI itself is actually paying off?

A little context: Block’s bet started in February 2026, when CEO Jack Dorsey cut more than 4,000 jobs and argued that AI had changed the economics of how the company could operate. That meant smaller teams equipped with increasingly capable intelligence tools could do more work, faster.
Six months later, there are signs that the operating model is changing. Block said it shipped 130 features in the first half of 2026, more than three times the 40 it shipped during the same period a year earlier. AI tools are now involved in nearly every production code change and review.
CFO Amrita Ahuja said the company was able to achieve record profitability while continuing to invest in growth, with AI helping increase product velocity.
Where the numbers stand
The numbers are significant because they show up alongside – not instead of – business growth. Square gross profit and gross payment volume each increased 13%. Cash App gross profit grew 31%. Consumer lending originations rose 59%. Block raised its full-year gross profit forecast to $12.51 billion and adjusted EPS growth forecast to 70%.

That makes Block a pretty clean case study for the emerging question of AI ROI. The company has cut costs, ramped up feature releases, and expanded its business all at once, suggesting that the operational changes were not coincidental.
However, the connection is not direct. The company still can’t isolate how much of that performance came from AI alone. The massive cost cuts, the shift in workforce, and the natural growth of the business all interact in ways that make a single cause-and-effect relationship difficult to prove.
Investors are watching closely to see if these gains hold as the initial cost savings fade and the company continues to pour resources into its artificial intelligence infrastructure.
