SMBs are racing into AI agents in 2026, but the ROI case is still catching up

Surveys from Upwork, Gartner, and the SBE Council show small and mid-size businesses deploying AI agents faster than larger peers — even as uncertainty about returns ranks as the second-biggest adoption barrier.

Small and mid-size businesses are pulling ahead of their enterprise peers in deploying AI agents, according to surveys published this spring by Upwork, Gartner, and the Small Business & Entrepreneurship Council. The catch is that the financial case for doing so hasn’t caught up with the urgency.

Upwork Research Institute’s Q1 2026 Business Leader Landscape, polling 750 U.S. SMB leaders across five industries, found 62% are “very confident” handing high-stakes tasks to AI agents and one in three now call agents mission-critical to company strategy. Only 3% said they weren’t considering agents in any form. Data analytics, content generation, and inventory management have already moved past pilot into scaled deployment.

The SBE Council’s April survey filled in the spending picture: 82% of small-business employers have invested in AI tools, the typical operator now runs a median of five, 93% plan to keep investing over the next year, and 62% intend to spend more.

Gartner’s macro numbers frame the appetite. Worldwide AI spending is forecast to hit $2.59 trillion in 2026, up 47% year over year, with AI agent software alone climbing from $206.5 billion in 2026 to $376.3 billion in 2027. By the end of 2026, Gartner expects 40% of enterprise applications to ship with task-specific agents, up from less than 5% a year earlier.

What’s notable is the discovery pattern. Upwork’s data shows SMB buyers learning about agents primarily through vendors (53%) and peer networks (52%), which is why the gap between enterprise platforms built for Fortune 500 procurement cycles and no-code agentic tools like LemonLime keeps widening. ROI uncertainty ranks as the second-biggest adoption barrier at 24%, just behind data security and compliance at 27%.

Gartner’s Helen Poitevin is blunt about why headcount math isn’t the answer. Around 80% of organizations have reported workforce reductions tied to AI, but those cuts, she warns, “do not appear to translate into ROI.” Her own team doesn’t expect autonomous business to be a net-positive job creator until 2028 to 2029.

That’s the structural read. SMBs are buying the future on a vendor-led timeline; the returns arrive on Gartner’s.
