What this means for brands
Product releases, funding, and feature rollouts are accelerating, not just more often, but faster in impact. What used to take quarters now happens in weeks: rapid model updates, swift feature launches, and bigger funding rounds compress platform shifts into much shorter windows. Brands must monitor continuously, experiment quickly, and automate optimization to stay visible in AI search.
Looking ahead to 2026, expect even faster shifts: a big surge in AI‑generated content (most won’t rank but some will), ad-supported AI search, new platforms brands must target, more consolidation and acquisitions, and continued blurring of paid and organic - see Killian Dunne’s 12 predictions for 2026 for a concise view: here
