B2B ecommerce pulse: AI agents, marketplace expansion, and digital investment drive mid-2026 momentum

B2B ecommerce entered one of its more eventful stretches in mid-2026, with manufacturers, distributors, marketplace operators, and platform vendors each reporting new digital initiatives or quantifiable results. The activity reinforces a macro picture that is already well-documented: the global B2B ecommerce market reached $20.4 trillion in 2024 and is projected to reach $36.1 trillion by 2031, according to Grand View Research data cited by Creatuity.

AI moves from pilot to production workflow

The most significant structural shift underway is AI graduating from internal experimentation to live commercial infrastructure. According to McKinsey's 2025 State of AI report, cited by Creatuity, 72% of organizations had adopted AI in at least one business function in 2025, up sharply from 55% in 2023. Salesforce data, also cited by Creatuity, shows 65% of B2B companies are now using or piloting AI for commerce operations including pricing, recommendations, and search.

Commercetools made that transition concrete in June, debuting a B2B Intake Agent developed in collaboration with radiation measurement company Mirion Technologies, according to MarketScale's reporting of Digital Commerce 360 coverage. The agent automates the front end of the order process, historically one of the most friction-heavy stages in complex B2B transactions. A day earlier, B2B ecommerce network Btab introduced an AI-powered alliance initiative aimed at expanding its merchant and buyer network, per the same source.

Search Engine Land notes that search interest in the term "AI agent" tripled in the past year, citing Exploding Topics data, a proxy for how quickly the concept has moved from specialist vocabulary to mainstream business priority. Adobe data, also cited by Search Engine Land, showed traffic from AI engines to retail sites was up 4,700% year-over-year as of July 2025, a figure that reinforces the scale of the underlying shift.

Kawasaki Engines USA posts a striking AOV result

Among the most concrete data points of the period, Kawasaki Engines USA reported a 500% increase in average order value through its B2B ecommerce channel, according to MarketScale's reporting of Digital Commerce 360's coverage from Salesforce Connections 2026. Average order value is a direct indicator of purchasing depth, and a fivefold increase suggests the company either shifted higher-complexity parts and equipment online, consolidated orders previously split across channels, or restructured its catalog to surface higher-value configurations to trade buyers.

The result illustrates a broader principle confirmed by Algolia and Salesforce research cited by Creatuity: AI-powered search and product recommendations can increase B2B conversion rates by 20–30%. Kawasaki's outcome sits well above that range, pointing to a more fundamental repositioning of what its digital channel is designed to sell.

Marketplace expansion and portal investment reflect a maturing channel

Faire, the wholesale marketplace known for connecting independent retailers with consumer brands, is extending access to business-use buyers, as reported by MarketScale citing Digital Commerce 360. The move is a deliberate push to capture procurement spend outside traditional retail, a segment that large horizontal marketplaces have long contested. A successful expansion would reposition Faire as a broader B2B purchasing destination rather than a purely wholesale-to-retail platform.

On the portal side, Sonos launched a dedicated B2B buyers' portal for dealers, and Nippon Sanso Matheson announced a platform unification effort as part of a broader digital transformation, both reported by MarketScale via Digital Commerce 360. Building distinct digital environments for trade customers, rather than routing them through consumer-facing infrastructure, has become standard practice among brands managing both direct-to-consumer and dealer channels, and Sana Commerce notes that 79% of B2B companies are now selling directly to consumers, up from 66% in 2024.

Distributor results diverge, but digital spend holds

Global Industrial reported Q1 sales growth of 9.2%, attributing the gain in part to digital investments that reinforced customer retention, per MarketScale's coverage of Digital Commerce 360's June 8, 2026 report. Retention-led framing matters here: it suggests the company's ecommerce infrastructure is functioning as a switching-cost mechanism, making reorders operationally easier than seeking alternative suppliers.

United Natural Foods (UNFI) told a different story for Q3 of its fiscal 2026, with sales falling even as the food distributor continued investing in digital capabilities and AI tools, according to MarketScale's reporting. The divergence between short-term revenue trends and ongoing digital spend is familiar in distribution, technology buildouts routinely lag their revenue impact by multiple quarters, and the UNFI case does not necessarily indicate a failed strategy so much as an incomplete one.

Buyer expectations are setting a new floor for digital investment

The commercial pressure behind all of this activity is a buyer base that has fundamentally changed in composition. Sana Commerce reports that 71% of B2B buyers are now Millennials or Gen Z, and 75% say they would switch to a supplier offering a better online buying experience. Creatuity's compilation of Salesforce data puts the self-service preference in sharper relief: 67% of B2B buyers prefer self-service portals over interacting with a sales rep for routine reorders and product information.

Only 17% of manufacturers currently use data to personalize buyer journeys, according to Sana Commerce, a gap that points to where competitive differentiation is most available. Creatuity's data from Boston Consulting Group adds a similar signal: only 18% of B2B companies describe their AI commerce maturity as "advanced," meaning the majority are still at a stage where investment can produce an edge rather than simply maintain parity.

Search Engine Land flags an additional consideration for B2B marketers: as AI agents increasingly influence and execute purchasing decisions, brands must optimize not just for human buyers but for the algorithms those buyers delegate to. Strategies such as answer engine optimization, schema markup, and agentic checkout modules are becoming prerequisites for visibility in an AI-mediated purchasing environment, a requirement that adds a new layer to already-complex B2B digital strategies.
