# Majority of B2B demand-generation will be AI-led by 2028

According to the **International Data Corporation (IDC)**, **62% of traditional B2B demand-generation will be AI-led by 2028**, signalling a massive shift away from traditional sales and marketing channels and reinforcing the urgency of [[concept-generative-engine-optimization-d1]].

**Confidence & external validation:** The enrichment overlay could not locate a public IDC document with the exact `62% by 2028` statistic — it is likely from an IDC proprietary forecast rather than a widely cited published figure. IDC *does* project rapid growth in AI-enabled marketing spend and automation (AI-powered CDPs, marketing clouds), so the **direction** (AI driving a majority of demand-gen by the late 2020s) is consistent with IDC's outlook. **Treat the 62% number as not independently verifiable.**
