Is it time for AI to enter the payback period and show its ROI?
- If AI is changing the economics of how businesses operate, where do we see its payoff?
- Block’s Q2’26 results suggest AI’s payoff may start showing up in familiar financial metrics. Whether the usual metrics are enough remains an open question.

Is it time for AI to enter the payback period and show its ROI?
AI’s contribution remains buried in the broader earnings numbers.
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.
That doesn’t prove AI is responsible for the improvement from head to toe. But it gives investors a real operating experiment to watch, which is relatively more useful than another AI product announcement at the moment.
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.
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.
But there is an important catch: the company still can’t isolate how much of that performance came from AI alone.
