Three-year projection — prospective method
Projecting to 2029 on a sector evolving at the speed of AI search requires humility. Nobody anticipated in 2022 that ChatGPT would be the dominant discovery channel for 38 % of B2B decision-makers in 2026. These 2029 projections are median scenarios based on observed 2024-2026 trajectories, to refresh every 6 months.
Trend 1 — GEO penetration reaches maturity
2026: 25 % of US B2B brands have a formalized GEO strategy. 2027: ~40 %. 2028: ~60 %. 2029: ~75 %, comparable to SEO penetration in 2015. Late adopters will pay 2-3x catch-up cost, exactly like brands that started SEO in 2014 vs 2008.
Trend 2 — Emergence of transactional LLM capabilities
2026: LLMs answer questions, don't process transactions. 2027-2028 expected: ChatGPT + e-commerce integration (already in alpha with Shopify), Perplexity + payment, Gemini + native Google Pay. Consequence: transactional brands (e-commerce, direct SaaS) will be as exposed to AI search as informational brands.
Trend 3 — Multimodal becomes mainstream
2026: LLMs primarily consume text. 2027-2028: multimodal models (GPT-5, Gemini Ultra, Claude Opus 5) massively consume images, videos, audio. Consequence: podcasts (transcribed or not), YouTube videos, brand images become direct GEO assets, not just indirect.
Trend 4 — AI regulation
EU AI Act in force 2025. US: federal framework expected 2027-2028 per political evolution. Mass-market LLMs will face strengthened transparency obligations (source explanation, editorial responsibility). Consequence for brands: documenting what LLMs say about your brand becomes a compliance best practice.
Trend 5 — Player consolidation
2026: 4 dominant LLMs (ChatGPT, Gemini, Claude, Perplexity) + 5-10 second-tier (Mistral, Cohere, Aleph Alpha...). 2028 expected: consolidation to 3-4 dominants, some second-tiers acquired (Mistral acquired?), Chinese new entrants (DeepSeek, Qwen) taking non-negligible US/EU share. Monitor panel to add new entrants.
2029 projected budget allocation
2029 B2B median: 50 % classic SEO + 50 % GEO. For premium B2B brands: 40 % SEO + 60 % GEO. For transactional B2C: 65 % SEO + 35 % GEO (transactional remains Google-dominated).
What remains uncertain
The mass-market LLM business model: pure subscription, ads, freemium? Emergence of AI-native search engines (beyond Perplexity)? Impact of future Google Core Updates on AI Overview? The role of open-source (Llama, Mistral) on mass-market LLM share? All these variables can reshuffle the deck in 12-18 months.
How to prepare
Three priorities for US B2B CMOs in 2026: (1) instrument GEO measurement now (before tool costs rise with market maturity), (2) build durable third-party authority (Wikipedia, established press) that survives algorithmic changes, (3) keep the team continuously trained on LLM evolutions (6-month cycles minimum).
