Current Brand Standings

How to Read the Standings

Presence rate is the share of qualified observations in which a brand is mentioned at all. Valid recommendation coverage is the share of qualified observations in which a brand appears in a recommendation-shaped response. Top-three rate and rank-one rate capture how prominently a recommended brand is positioned. Net sentiment scores the tone of brand mentions on a scale where higher is more positive. For formulas and denominator rules, see AI Market Discovery Metric Definitions.

Recommendation Coverage Movement

Largest Decline: Wallbox Pulsar Plus

Wallbox Pulsar Plus recorded the largest movement in the benchmark, with valid recommendation coverage falling to 16.1% in August 2026 from 23.7% in July 2026, a decline of 7.6 percentage points.

Category Leader: ChargePoint Home (ChargePoint Holdings)

ChargePoint Home (ChargePoint Holdings) remains the coverage leader at 57.6% in August 2026, down from 61.5% in July 2026. While coverage declined modestly, rank-one rate fell more sharply to 23.8% in August 2026 from 31.4% in July 2026. The leading position remains stable.

Recommendation Placement Snapshot

Coverage alone does not show how prominently a brand is recommended. The leading cluster shows meaningful differences in first-position rates even where coverage is close.

ChargePoint Home (ChargePoint Holdings) was recommended first in 23.8% of August 2026 observations, barely ahead of Tesla Wall Connector (Tesla, Inc.) at 21.8%, even though ChargePoint Home (ChargePoint Holdings) held a 7.4 point coverage lead. Close coverage can still hide very different first-position rates.

Buyer-Intent Distribution

All qualified observations in both months fell into the Brand Recommendation class.

The current public series measures Brand Recommendation discovery only and does not yet contain qualified observations in Pricing & Value or Multi-Brand Comparison.

Historical Measurement Record

This is an evergreen benchmark URL. New measurements are added to the same report.

Evidence and Source Layer

The benchmark is built from prompt-level observations that retain the query, AI/search surface, answer, brand outcome, recommendation placement, sentiment, and, where exposed, citations or attributable evidence sources. Source presence is evidence about the information environment. It is not automatically proof that the source caused the recommendation.

Scope Boundaries

This public benchmark does not measure market share, attributable sales, every possible AI response, organic-search ranking, social mention volume, private or sponsored channels, or causality from a metric movement alone. It records the change; it does not, by itself, establish why the change occurred.
