Visibility is only an asset when it is accurate. An AI that mentions your brand with the wrong pricing, an outdated feature claim, or a confused founder name can do real damage at scale. This benchmark measures how often AI states correct facts about brands, using first-party data from the Presenc AI platform across 2,400+ brands and 18 industries. It quantifies accuracy overall, by error type, and by platform for 2026.
Accuracy rate is the share of brand-fact statements in AI answers that are verifiably correct against the brand's own public source of truth. Each incorrect statement is classified by error type.
Brand Fact Accuracy by Category
Stable, well-documented facts like company description are reliable. Fast-changing facts like pricing are where accuracy collapses.
| Fact Category | Accuracy Rate | Top Quartile | Bottom Quartile | Most Common Error |
|---|---|---|---|---|
| Company description | 91% | 97% | 82% | Outdated positioning |
| Founder / leadership | 84% | 94% | 71% | Former exec listed |
| Core features | 78% | 90% | 64% | Deprecated feature |
| Pricing | 61% | 76% | 44% | Stale price tier |
| Integrations | 69% | 83% | 52% | Missing new integration |
| Funding / metrics | 66% | 81% | 48% | Old funding round |
Pricing is the least reliable fact category at a 61% accuracy rate, with stale tiers the dominant error. Company descriptions are the most reliable at 91%, because positioning changes slowly and is widely echoed across sources.
Accuracy and Error Types by Platform
Platforms differ in both overall accuracy and how they fail. Retrieval-grounded engines are more accurate but more likely to surface stale cached facts.
| Platform | Overall Accuracy | Outdated Errors | Fabricated Errors | Conflation Errors |
|---|---|---|---|---|
| Perplexity | 82% | 61% | 14% | 25% |
| Gemini | 79% | 57% | 19% | 24% |
| Claude | 78% | 52% | 22% | 26% |
| ChatGPT | 76% | 49% | 26% | 25% |
Perplexity is the most accurate at 82% but its errors skew heavily toward outdated facts at 61% of all errors. ChatGPT trails at 76% overall and produces the largest share of fully fabricated facts at 26%, where a detail is invented rather than merely stale.
Key Findings
- Pricing is the accuracy weak point. At 61%, nearly four in ten pricing statements are wrong, almost always a stale tier rather than a fabrication.
- Outdated facts dominate errors. Across platforms, 49% to 61% of all errors are stale rather than invented, meaning most damage is fixable through fresh, authoritative sources.
- Retrieval improves accuracy. Perplexity leads at 82% overall, 6 points above ChatGPT, showing that grounding reduces fabrication even as it raises stale-fact risk.
- Conflation is steady at about 25%. Across every platform, roughly a quarter of errors confuse one brand with a competitor, a risk that rises in crowded categories.
Methodology
Figures are aggregated from the Presenc AI monitoring platform via continuous prompt testing across major AI platforms including ChatGPT, Claude, Gemini, Perplexity, and others, representing 2,400+ brands across 18 industries. Each brand-fact statement is checked against the brand's own public source of truth and classified by error type. Estimates are used where public data is unavailable, and benchmarks are reviewed quarterly. Last update June 2026.
