| Statistic | Figure | Source |
|---|---|---|
| Buyers starting vendor research in an AI chatbot (vs. April 2025's 29%) | 51% | G2, March 2026 |
| Buyers relying on AI chatbots for software research | 71% | G2, March 2026 |
| Buyers who switched vendor choice due to AI guidance | 69% | G2, March 2026 |
| Buyers who bought from a previously-unknown vendor | 1 in 3 | G2, March 2026 |
| Projected traditional search volume decline by 2026 | −25% | Gartner, Feb 2024 |
| Projected organic search traffic decline by 2028 | −50%+ | Gartner, Feb 2024 |
What the Numbers Mean Together
Three findings stand out when the data is read as one picture:
- AI-first research overtook search in under a year. The move from 29% to 51% chatbot-first research between April 2025 and March 2026 is one of the fastest channel shifts in B2B buying behavior on record.
- Brand recognition is no longer the primary filter. One in three purchases going to a previously unknown vendor means AI-generated shortlists are actively displacing brand familiarity as the first filter in vendor selection.
- The shift compounds category by category. G2 frames this as the third great compression of the buyer journey (directories, then search engines, now AI answers) each concentrating discovery into a smaller number of moments a vendor must win.
