Large language models exhibit a "rich get richer" bias that favors established brands by a 3.2x margin, effectively closing off the discovery funnel that traditionally allowed smaller competitors to gain visibility through search. The advantage runs deeper than algorithmic choice: these models learn from training data skewed heavily toward popular, well-documented brands, embedding incumbency into their recommendations. For consumer goods and DTC startups, AI-powered search gatekeepers are narrowing shelf space rather than expanding it.
