How AI Search Is Recommending Moving Container Companies: Monthly Trends

Executive Summary

U-Pack (ABF Freight / ArcBest) is the category leader in September 2026 with valid recommendation coverage of 48.5%, a narrower lead than the category has seen in recent months. The gap to the next brand, U-Haul at 42.5%, is 6.0 points. This is a significant repositioning month: the category leader's coverage has declined from 59.9% in July 2026, and the prior month's leader, U-Haul Holding Co. (U-Box), recorded zero coverage in September 2026, reflecting a return to the U-Haul entity naming.

U-Haul is the most consequential upward mover this month, with coverage rising 42.5 points from 0.0% in August 2026 to 42.5% in September 2026. The brand holds 222 valid recommendations out of 522 qualified observations, with a rank-one rate of 15.1% and 79 rank-one placements. This follows an instrument-level identity shift in August 2026, when the entity was tracked under U-Haul Holding Co. (U-Box).

The sharpest decliners relative to the July 2026 baseline are concentrated among the category's largest brands. U-Haul is down 13.2 points from 55.7%, U-Pack (ABF Freight / ArcBest) is down 11.4 points from 59.9%, and PODS Enterprises, LLC is down 7.1 points from 30.7%. Collegeboxes is also down 3.8 points from 5.7%, a significant decline from a small base.

The month is defined by compression at the top. Where July 2026 saw U-Pack (ABF Freight / ArcBest) at 59.9% and U-Haul at 55.7%, September 2026 has the leader at 48.5% and the second-place brand at 42.5%. Four brands recorded significant declines from baseline, and no brand posted a significant rise, making this a broad redistribution rather than a single competitive shift.

Each monthly run begins with 800 prompt-surface observations (541 unique questions in July 2026, 548 in August 2026, and 600 in September 2026) across the benchmark's defined AI/search surface universe. Of those, 800 mentioned a tracked brand or competitor in July and August 2026, and 799 did in September 2026; 773 were relevant and 27 were irrelevant in July, 791 were relevant and 9 were irrelevant in August, and 770 were relevant and 29 were irrelevant in September. The public metrics use the 524 qualified observations in July 2026, 529 in August 2026, and 522 in September 2026 that survive both qualification stages.

Key Findings

Benchmark Context

The report separates the raw collection universe from the qualified analysis set. Brand-level recommendation percentages are calculated within the qualified benchmark set.

August 2026, the intermediate month, saw 529 qualified observations with 791 relevant and 9 irrelevant prompts. The identity shift between U-Haul and U-Haul Holding Co. (U-Box) occurred in that month and is now reversed in the September series.

Benchmark-Level Metrics

The August 2026 intermediate month saw recommendation-shaped answer share rise to 37.2% and valid recommendation shortlist share reach 53.3%, making September's decline a reversal of that single-month spike. The valid recommendation shortlist share of 43.5% is the lowest of the three-month series.

AI Recommendation Trend

Category Leadership Retained But Significantly Compressed

U-Pack (ABF Freight / ArcBest) retains the coverage lead it held in July 2026, but its margin has narrowed considerably. At 48.5% in September 2026, the brand is 6.0 points above U-Haul at 42.5%, and the overall distribution has tightened across the middle of the category.

The category-level change came from the combination of several significant declines among the largest brands rather than from any single riser. U-Haul Holding Co. (U-Box) recorded zero coverage in September 2026, and its August 2026 figure of 57.1% is now attributed to the U-Haul entity following the benchmark naming restoration.

What Changed This Month

U-Pack (ABF Freight / ArcBest)

U-Pack (ABF Freight / ArcBest) remains the category leader, but its valid recommendation coverage is down 11.4 points from 59.9% in July 2026 to 48.5% in September 2026, a significant decline over the three-month series. The brand holds 253 valid recommendations out of 522 qualified observations in September, down from 314 out of 524 in July.

The August-to-September change was smaller: coverage fell 5.9 points from 54.4%, marking a second consecutive month of decline for the brand. The brand's top-three rate also declined, from 38.9% in July to 33.0% in September, while its rank-one rate slipped from 9.3% to 7.7%.

The brand's raw mention presence rose 2.9 points, from 88.9% in July to 91.8% in September, meaning it is appearing in more responses even as its recommendation coverage declines. Presence is up while recommendation coverage is down.

Highest-priority diagnostic: Which prompts previously produced a U-Pack (ABF Freight / ArcBest) recommendation that now surface a different brand, and what attributes are being cited in the replacements.

U-Haul

U-Haul is the largest upward mover from the prior month, with valid recommendation coverage rising 42.5 points from 0.0% in August 2026 to 42.5% in September 2026. The brand holds 222 valid recommendations out of 522 qualified observations in September. Measured against the July 2026 baseline of 55.7%, coverage is down 13.2 points, a significant decline.

The August 2026 zero reflects the benchmark's temporary tracking of this entity as U-Haul Holding Co. (U-Box), which recorded 57.1% coverage that month with 302 valid recommendations out of 529 observations. September's rise to 42.5% represents a return to the original entity name, not a fresh competitive gain.

The brand's top-three rate is 28.2% in September 2026, down 8.1 points from 36.3% in July 2026. Its rank-one rate of 15.1% is essentially unchanged from baseline, with 79 rank-one placements in both periods. Raw mention presence remains near-universal at 98.7%, compared with 99.2% in July.

U-Haul remains the most frequently surfaced brand in the category, but its recommendation coverage has compressed even after the naming restoration: the brand is visible in nearly every qualified response but is recommended in fewer of them than in July.

Highest-priority diagnostic: Which specific prompts shifted from U-Haul to another brand between July and September 2026, and whether the August identity tracking fully explains the baseline decline.

PODS Enterprises, LLC

PODS Enterprises, LLC is the sharpest prior-month decliner, with coverage down 11.6 points from 35.2% in August 2026 to 23.6% in September 2026, a significant movement. Measured from the July 2026 baseline of 30.7%, coverage is down 7.1 points, also a significant decline.

The brand holds 123 valid recommendations out of 522 qualified observations in September 2026, down from 186 out of 529 in August. Measured against the July 2026 baseline, raw mention presence fell 3.0 points, from 75.0% to 72.0%, and the top-three rate declined 3.2 points, from 19.7% to 16.5%.

The brand also recorded 17 negative mentions in September 2026, up from 10 in August and 5 in July, a rising negative sentiment count in a category where most tracked brands have zero negative mentions.

Highest-priority diagnostic: Which prompts and surfaces drove the sharp August-to-September decline, and what distinguishes the responses carrying negative sentiment from those with neutral or positive framing.

Collegeboxes

Collegeboxes is a significant decliner from baseline, with coverage down 3.8 points from 5.7% in July 2026 to 1.9% in September 2026. The brand holds 10 valid recommendations out of 522 qualified observations, down from 30 out of 524 in July. This is a small-count movement and should be read cautiously.

The brand's raw mention presence fell 3.4 points, from 9.0% to 5.6%, while its top-three rate dipped 0.4 points, from 1.9% to 1.5%. Its rank-one rate held steady at 1.1% with 6 rank-one placements in both periods. The prior-month change was an increase of 1.1 points from 0.8% in August 2026, which was not significant.

Highest-priority diagnostic: Which prompts previously surfaced Collegeboxes and no longer do, and whether the brand's small absolute counts make the observed movement a function of a handful of queries.

Buyer-Intent Interpretation

In September 2026, all 522 qualified observations fell into the Brand Recommendation cluster (discovery and consideration). No qualified observations were recorded in the Pricing & Value or Multi-Brand Comparison clusters. The public benchmark currently measures which brands are recommended when a buyer asks for a moving container company, but it cannot yet answer commercial questions about pricing positioning, value perception, or head-to-head comparison outcomes. Those questions would require a separate analysis targeting those specific query types.

Brand Opportunity Summary

The benchmark identifies where attention is warranted; a company-level analysis is needed to explain why.

Evidence Behind the Benchmark

The aggregate metrics are built from prompt-level observations (query, surface, recommendation outcome, rank, sentiment, and citations where exposed). Company-level analysis can go deeper into prompt, competitor, surface, and evidence patterns. Source presence is not automatically treated as proof of causation.

Report-Specific Interpretation Notes

• The U-Haul to U-Haul Holding Co. (U-Box) transition in August 2026 was a benchmark identity change, now reverted; movement between these two entities should be read as a naming shift, not a competitive gain or loss.
• Small-count movements, such as Collegeboxes at 10 valid recommendations, Go Mini's Franchising, LLC at 1, and UNITS Moving and Portable Storage, Inc. at 10, should be read cautiously given the small observation base.
• The qualified denominator (522 observations) differs from the raw collection universe (800 prompts); percentages are calculated within the qualified set.
• Directional analysis identifies changes worth investigating; it does not establish cause.

Next Step

The Public Benchmark Shows Where a Brand Is Winning or Losing. A Company-Level Audit Shows Why.

Beneath the aggregate coverage percentages lie the questions that matter: which high-intent prompts are won, which competitor takes the recommendation when a brand loses, what attributes AI systems associate with each option, and which external sources shape those answers. The September 2026 compression across the category's largest brands raises precisely these questions: whether the declines are concentrated in specific query types, surfaces, or evidence sources.

A company-specific AI visibility audit maps those prompt, surface, competitor, ranking, sentiment, and evidence-source patterns into a prioritized visibility strategy. It turns the benchmark's findings into a diagnostic that explains why the AI conversation is moving in a particular direction.
