Report Card

Executive Summary

Digital Realty is visible but under-recommended in the Real Estate Investment Trusts category. The benchmark shows the company surfacing in 52.3% of qualified observations in September 2026, the fourth-highest raw mention presence rate among ten tracked brands, yet converting to a valid recommendation in only 14.4% of observations, which ranks sixth. That 37.9-point gap between presence and recommendation coverage is the central finding of this report.

The company's September 2026 position reflects a category where recommendation concentration is high at the top. Realty Income leads at 22.6% valid recommendation coverage, followed by Prologis at 21.4%, Equinix at 20.7%, and American Tower at 19.4%. Digital Realty sits 5.0 points behind American Tower and 8.2 points behind the category leader. The gap is meaningful because the top four brands are separated by only 3.2 points, meaning Digital Realty is one strong month away from entering that cluster.

The clearest positive signal is presence growth. Digital Realty's raw mention presence rose 13.0 points from 39.3% in July 2026 to 52.3% in September 2026, the largest presence gain of any tracked brand over that period. Valid recommendation coverage rose 2.8 points over the same span, from 11.6% to 14.4%. The analysis found that presence grew roughly 4.6 times faster than recommendation coverage, indicating the brand is being surfaced in more AI answers without being converted into more recommendations at a proportional rate.

The clearest weakness is rank-one performance. Digital Realty holds a rank-one rate of 0.7% in September 2026, with only 4 rank-one placements across 589 qualified observations. By comparison, Realty Income holds 42 rank-one placements, Prologis 39, and Equinix 36. The company is being included in recommendation lists but rarely placed first.

Platform-level data shows Digital Realty's strongest recommendation signal on Gemini, where it holds 23.8% valid recommendation coverage and a net sentiment score of 0.7619, the highest sentiment reading of any platform for the brand. Its weakest platform signal is Copilot, where it holds 1.5% valid recommendation coverage and a net sentiment score of 0.0870. The observed data suggests the brand's AI recommendation footprint is uneven across platforms rather than uniformly weak.

The benchmark also shows that all qualified observations in September 2026 fell into the Brand Recommendation cluster. No qualified observations were recorded in the Pricing and Value or Multi-Brand Comparison clusters, which means the public benchmark cannot yet measure how Digital Realty performs in cost, yield, or head-to-head comparison conversations. For a category where income characteristics drive much of the investment conversation, this is a material measurement gap.

What Digital Realty Is Winning

Questions This Section Answers

• Where is Digital Realty gaining the most ground in AI visibility?
• Which platform produces the strongest recommendation signal for Digital Realty?
• How does Digital Realty's sentiment compare to the category leaders?

Digital Realty's strongest evidence-backed win is presence growth. The benchmark shows raw mention presence rising 13.0 points from 39.3% in July 2026 to 52.3% in September 2026, the largest gain of any tracked brand. This means AI systems are surfacing Digital Realty in more answers than they were three months ago.

The company's second win is Gemini performance. On Gemini, Digital Realty holds 23.8% valid recommendation coverage, 9.5% top-three rate, and a net sentiment score of 0.7619. That sentiment score is the highest of any platform for the brand and among the highest in the category. The analysis found that Digital Realty's Gemini coverage of 23.8% exceeds its overall category coverage of 14.4% by 9.4 points, indicating the platform is a relative strength.

The third win is sentiment quality. Digital Realty carries zero negative mentions across all 589 qualified observations in September 2026. Its net sentiment score of 0.4286 ranks fourth in the category, behind Realty Income at 0.5766, Prologis at 0.4499, and Equinix at 0.4394. The framing quality of mentions that do occur is positive.

These wins are real but narrow. The company has presence and positive framing but has not converted either into top-three or rank-one recommendation positions at scale.

Where Digital Realty Has the Clearest AI Visibility Gaps

Questions This Section Answers

• Why does Digital Realty's recommendation conversion lag behind its visibility?
• Where is Digital Realty losing top-three and rank-one placement to competitors?
• Which platform shows the largest gap between Digital Realty's strongest and weakest recommendation coverage?

The clearest gap is recommendation conversion. Digital Realty appears in 52.3% of qualified observations but receives valid recommendation credit in only 14.4%. That means roughly 72% of the time the brand is mentioned, it is not recommended. By comparison, Realty Income appears in 42.1% of observations and converts 22.6% to valid recommendations, a conversion ratio of roughly 54%. Prologis appears in 62.6% and converts 21.4%, a ratio of roughly 34%. Digital Realty's conversion ratio of roughly 28% trails both.

The second gap is top-three placement. Digital Realty holds a top-three rate of 6.8% in September 2026, compared with Prologis at 15.6%, Realty Income at 13.4%, Equinix at 11.7%, and American Tower at 10.2%. The company is being included in recommendation lists but is not being placed in the top three at the rate its presence would suggest. The benchmark shows 40 top-three placements for Digital Realty versus 92 for Prologis and 79 for Realty Income.

The third gap is rank-one performance. Digital Realty holds a rank-one rate of 0.7%, with 4 rank-one placements in September 2026. Realty Income holds 42, Prologis 39, Equinix 36, and Welltower 16. The company is rarely the first recommendation AI systems surface.

The fourth gap is platform inconsistency. On Copilot, Digital Realty holds 1.5% valid recommendation coverage and a net sentiment score of 0.0870, with only 1 valid recommendation across 69 observations. On ChatGPT, it holds 27.1% coverage, and on Gemini 23.8%. The gap between its strongest and weakest platform is 25.6 points. The source pattern may indicate that the brand's public evidence layer is more retrievable on some platforms than others.

The fifth gap is competitive displacement. The benchmark shows American Tower, the category's only significant riser, gaining 4.8 points of coverage from July to September 2026 while Digital Realty gained 2.8 points. American Tower's gap to Equinix narrowed from 7.9 points to 1.3 points over that period. Digital Realty's gap to the top three remains wider than American Tower's, meaning the company has not yet closed distance to the leaders at the same rate.

Biggest Opportunity

Questions This Section Answers

• What would change if Digital Realty converted existing presence into top-three recommendations at Prologis's rate?

The single biggest opportunity is converting existing presence into top-three and rank-one recommendations. Digital Realty already appears in more than half of qualified observations. The company does not need more visibility. It needs the visibility it already has to convert into recommendation placement.

The benchmark shows the company holds 40 top-three placements and 4 rank-one placements against 308 total mentions. If Digital Realty converted presence to top-three placement at Prologis's rate, it would hold roughly 92 top-three placements instead of 40. The path from reference to recommendation runs through the prompt, page, and citation layers that AI systems retrieve when forming a shortlist. The company's Gemini performance, where it holds 23.8% coverage and 0.7619 sentiment, shows the conversion is achievable on at least one platform.

Competitive Landscape

Questions This Section Answers

• Where does Digital Realty rank against Prologis, Realty Income, and Equinix on placement and sentiment?
• Which competitor is closing the gap to the category leaders fastest?

Realty Income, Prologis, and Equinix hold the strongest recommendation-stage positions in the Real Estate Investment Trusts category for September 2026, with American Tower closing rapidly. Digital Realty sits in the second tier, visible but under-recommended relative to its presence.

Average recommended rank covers rank-eligible recommendations only.

Digital Realty ranks sixth of ten by top-three rate and sixth by rank-one rate. Its average recommended rank of 3.6081 is the fifth-best in the category, ahead of Crown Castle, Simon Property Group, Public Storage, and AvalonBay Communities, but behind the top four brands. The table shows the company is closer to the top four on sentiment than on placement, which suggests the framing of its mentions is competitive even when its position is not.

Why This Matters

Questions This Section Answers

• Why does appearing in AI answers not translate into being recommended?
• What determines whether an AI mention becomes a valid recommendation?

AI systems are now forming the buyer shortlist before a human ever visits a website. For Digital Realty, the benchmark shows the company is already in the room: it appears in more than half of qualified AI observations. But appearing is not the same as being recommended. The company holds 4 rank-one placements against 308 mentions, which means the recommendation moment is being won by competitors even when Digital Realty is visible.

The next move is targeted correction of the prompt, page, and citation layers that determine whether a mention becomes a recommendation. The benchmark identifies where attention is warranted. A company-level analysis explains why the gap exists and what to fix first.

Core Metrics

Sentiment Score

Questions This Section Answers

• Why is classified sentiment required before interpreting AI visibility?
• What does the gap between Digital Realty's sentiment rank and recommendation coverage rank indicate?

Sentiment Score = (positive mentions × 1 + neutral mentions × 0 + negative mentions × -1) / total mentions

For Digital Realty in September 2026: (132 × 1 + 176 × 0 + 0 × -1) / 308 = 0.4286.

This matters because unclassified mention counts are misleading. A brand that appears in 308 answers but is only positively framed in 132 of them is not equally visible to a brand with the same mention count and stronger framing. Share of voice is a diagnostic metric, not a business KPI. A positive recommendation, a neutral reference, a cautionary mention, and a competitor-displaced mention are not equal. Counting all mentions as wins is bad measurement. Classified sentiment is required before interpreting AI visibility, because it separates presence from framing quality.

Digital Realty's sentiment score of 0.4286 ranks fourth in the category, behind Realty Income at 0.5766, Prologis at 0.4499, and Equinix at 0.4394. The company carries zero negative mentions, which means its framing is either positive or neutral. The gap between its sentiment rank (fourth) and its recommendation coverage rank (sixth) suggests the brand is framed well when mentioned but is not mentioned in enough recommendation contexts.

Methodology

1. This report is a benchmark-based analysis of Digital Realty's position in the Real Estate Investment Trusts category, using the LLM Authority Index AI Market Discovery Index for September 2026 and the associated metrics aggregation file.
2. The reporting window is September 2026, with comparison points from July 2026 and August 2026 where the benchmark provides them.
3. Six AI/search surface families were tracked: ChatGPT, Copilot, Gemini, Perplexity, AI Overviews, and AI Mode. All six produced qualified observations in September 2026.
4. The September 2026 run began with 800 prompt-surface observations and produced 589 qualified observations after qualification. Brand-level percentages use the qualified set as the public denominator.
5. Ten brands were tracked: American Tower, AvalonBay Communities, Crown Castle, Digital Realty, Equinix, Prologis, Public Storage, Realty Income, Simon Property Group, and Welltower.
6. One qualified buyer-intent cluster was represented in September 2026: Best REITs and Top Real Estate Investment Trusts, classified as a Brand Recommendation cluster at the consideration stage. No qualified observations were recorded in the Pricing and Value or Multi-Brand Comparison clusters.
7. Stage 0 extraction retained the query, the AI/search surface, the full answer, the brand outcome, recommendation placement, sentiment, and, where exposed, citations or attributable evidence sources.
8. A mention is counted when Digital Realty appears anywhere in a qualified AI response, regardless of whether it is recommended.
9. A valid recommendation is counted when Digital Realty appears in a valid recommendation shortlist, as marked by the dataset. Negative, neutral, cautionary, comparison-anchor, and listed-only mentions are not counted as valid recommendations.
10. Top-three rate measures the share of qualified observations where Digital Realty appears in the top three recommended positions. Rank-one rate measures the share where it is the first or only recommendation. Average recommended rank covers rank-eligible recommendations only.
11. The public benchmark does not measure market share, sales attribution, organic search ranking, social media sentiment, private or sponsored channel behavior, brand-specific query volume drivers, or causality from any single metric movement.
12. The unique question count for September 2026 was 529. The benchmark does not publish a unique prompt count for the public version. Several brands in the category carry small valid-recommendation counts, and percentage movements for those brands should be read with that scale in mind.
