The short version

THE SHORT VERSION: TrustRadius's 2026 B2B Buying Disconnect Report finds that 63% of buyers now use AI during their purchase research, but 94% of them fact-check AI before trusting what it says. Trust in vendor content is falling even as AI use rises, with 47% of buyers saying they trust online resources less than they did a year ago.

What happened

TrustRadius, an HG Insights company, published its 2026 B2B Buying Disconnect Report on July 15, 2026, based on responses from 1,862 technology buyers and 444 technology vendors. The headline finding: AI adoption in B2B research is accelerating, with AI tools or AI-featured products making up 59% of the purchases buyers made in the past year, but adoption hasn't translated into blind trust. The report found buyers ranked product demos, free trials, prior experience, and user reviews as their most influential resources, while vendor marketing collateral ranked last. Analyst reports, once a staple of enterprise buying, were used by just 13% of buyers to make a purchase decision, a 63% drop since 2022. Peer recommendations were trusted by 73% of decision-makers, compared with 55% who trust vendor websites.

AI made research faster, not more credible by default. Buyers are running more queries and covering more ground, but they're layering human verification on top of every AI-sourced claim before it influences a decision. That's a shift from the last few years, when a well-optimized vendor page or a placement in an analyst report could carry real weight on its own. Now the content that survives buyer skepticism is content a real customer or reviewer stands behind, because that's the layer buyers still trust enough to skip fact-checking.

  1. Stock your product with reviews before you invest in more collateral
    With vendor marketing content ranked dead last in buyer trust, a page of fresh, specific G2 or TrustRadius reviews will do more to move a stalled deal than another one-pager. Prioritize review generation over redesigning sales assets this quarter.
  2. Build a live demo and trial path into every high-intent page
    Demos and free trials outrank every other resource in the report. If your pricing or product page doesn't link to a self-serve trial or a bookable live demo within two clicks, that's the fix with the highest leverage right now.
  3. Assume your AI-cited content will get double-checked
    Write claims on your site the way you'd want them to survive a skeptical buyer re-verifying them against a review site or a customer call. Vague superlatives get flagged; specific, sourced numbers survive the fact-check.

By the numbers: Trust in online vendor resources is moving in the wrong direction even as AI use grows: the share of buyers who say they trust online resources less than a year ago rose from 39% to 47% in the 2026 report, with 83% of buyers shortlisting three or fewer products before deciding.

"Buyers are using AI to move faster, not to think less. They want speed, but they still want the efficiency of AI synthesis and the confidence of verified sources, and those two things have to coexist."

What to do this week

Pull your last 10 closed-lost deals and check how many stalled after a buyer went looking for reviews or a peer reference you didn't provide. Then send your 10 most recent happy customers a direct ask for a G2 or TrustRadius review this week, buyers are weighting that content over anything your own site says.
