What this article covers

This week, ChatGPT’s software recommendation set expanded from 467 to 493 ranked brand slots across 10 categories (GPT-5.4, US). AskLab was the biggest gainer (+21.5 DECA, in GEO) and Otterly.AI the biggest faller (−29.9, also GEO) — and in two categories, CRM and Marketing Automation, the previous #1 took the lead right back (Dynamics 365 Sales and Braze). Below: the three biggest movers, a category-by-category opportunity map, and how to read a one-week change. Not seeing your category below? Treat this report as a sample chart — DecaGEO can map the same view for your market: who ChatGPT recommends, who’s rising, and how hard the category is to enter.

Summary for citation: In DecaGEO’s week of June 28, 2026 data (ChatGPT GPT-5.4, US, 10 categories, 493 ranked brand slots), the largest gainer was AskLab (+21.5 DECA to #5 in GEO) and the largest faller was Otterly.AI (−29.9 in GEO). Last week’s GEO surge split: Scrunch AI consolidated to #2 (96, +11), while Profound (−25.7) and Otterly.AI (−29.9) reversed. Dynamics 365 Sales retook CRM #1 from Zoho CRM, with HubSpot Sales Hub rebounding +16.0 to #3. Braze retook Marketing Automation #1 as last week’s new leader Adobe Marketo Engage fell −26.2 to #5. GEO was again the most volatile board (23 of 103 brands moved ±10 ranks). The tracked set widened from 467 to 493 brand slots.

Key takeaway: A single week’s move is an observation, not a buying signal. Three weeks in, the categories that changed leaders last week mostly reverted this week — read direction and magnitude across 2–3 weeks, not one reading.

This week’s biggest moves

GEO’s surge sorted itself out — one tool stuck, two reversed. Last week three GEO-native tools jumped together; this week they split. Scrunch AI consolidated to #2 (DECA 96, +11), now just ~4 points behind Semrush at #1. But Profound fell −25.7 to #3 and Otterly.AI dropped −29.9 to #4 — the biggest faller in the index — giving back most of last week’s gains. Meanwhile AskLab rose +21.5 to #5, almost exactly reversing its own drop the week before. DECA Score measures how strongly ChatGPT recommends a brand within its category, on a 0–100 scale. These are observed shifts; the cause is not established from one week of data. The CRM #1 changed hands again. Dynamics 365 Sales rose +10 to retake #1 (DECA 100) from Zoho CRM (now #2), which had taken the spot only last week. HubSpot Sales Hub rebounded +16.0 to #3 — reversing last week’s −19.2. Over three weeks the CRM crown has gone Dynamics → Zoho → Dynamics. The HubSpot–Agentforce race below it is tracked in HubSpot Sales Hub vs Agentforce Sales. Marketing Automation flipped back to Braze. Braze rose +9 to reclaim #1, while last week’s new leader Adobe Marketo Engage fell −26.2 to #5. Braze → Marketo → Braze in two weeks. When the top oscillates like this, one week’s #1 isn’t a trend — it’s a snapshot. Want the deeper read on any mover?

The tracked set keeps wobbling upward (440 → 473 → 467 → 493)

Stepping back from individual movers: the number of brands ChatGPT placed in its recommendation set across these 10 categories rose from 467 to 493 this week — up 26, or about 6%. Seen across four weeks, the level drifts up but doesn’t move in a straight line: Table 1: Ranked brands per category, weeks of June 7–28, 2026. Source: DecaGEO, ChatGPT (GPT-5.4), US. Read the level and the multi-week shape, not the weekly tick. The clearest sustained climb is GEO (74 → 88 → 91 → 103); most other categories oscillate within a narrow band (Email Marketing has sat at 40–45 all month). Much of any week’s change overlaps newly detected or re-aggregated brands, so confirm a direction over 2–3 weeks rather than reading a single week as a trend. For a brand that isn’t recommended yet, the structural signal still holds: the list ChatGPT draws from is moving week to week, not fixed. The set is decided week by week, not once. This index covers 10 categories today. Don’t see your category here? That’s a gap in the index, not a verdict — request a chart for your category and DecaGEO will check whether ChatGPT recommends brands in it and send you the first chart.

Category opportunity map

Each category has a different shape: how locked the top is (the #1-vs-#2 gap), how much the board churned, and who rose or fell. Table 2: As of the week of June 28, 2026 · ChatGPT (GPT-5.4), US. Risers and fallers by DECA Score change vs June 21. Open any category’s live board: CRM, SEO, GEO, Email Marketing, Marketing Automation, Project Management, Help Desk, Influencer Marketing, AI Writing Assistants, AI Image Generators. Three categories churned most — GEO (23 of 103 brands moved ±10 ranks), SEO (11 of 63), and Project Management (8 of 52). Three were calmest, with almost no rank movement: Help Desk, AI Writing Assistants, and CRM. The top is hardest to challenge in SEO, AI Image Generators, and Email Marketing (large #1-vs-#2 gaps), and most contestable in GEO and Influencer Marketing (about 4–5 points) and CRM (7 points).

What this means for you

Every reader splits first on one question: is your category tracked in the index at all? The positions below only apply once it is. If your category isn’t tracked yet. Not appearing in the 10 above isn’t a verdict — the index keeps adding names (GEO +12, CRM +10 this week; the universe up to 493). Request a free category chart to see whether ChatGPT recommends your brand, which competitors appear first, and how far you are from the Top 5. Requested categories are prioritized by demand. If your category is tracked, read your position:

• Not yet recommended. Start where the entry bar is lowest and the board is least crowded — Help Desk and AI Image Generators are less dense than GEO or SEO. Note that GEO has a low entry score but is the most volatile board, three weeks running.
• Mid-pack. In the churning boards (GEO, SEO, Project Management), measure your gap to the fifth-place score and watch which moves stick — this week showed Scrunch AI holding its gain while Profound and Otterly.AI gave theirs back. A two-week hold means more than a one-week jump.
• Stable or leading. GEO, Influencer Marketing, and CRM leaders sit on moats of about 4–7 points — thin enough to track challengers weekly. See the live board to monitor who’s closing in.

Don’t see your category?

Not appearing in the 10 categories above isn’t a verdict that ChatGPT is silent in your market — it more likely means the category hasn’t been mapped yet. A category chart answers four questions:

• Who does ChatGPT recommend first?
• Which brands are entering the recommendation set?
• How high is the Top 5 threshold (the DECA Score needed to break in)?
• Is the category open, volatile, or locked?

FAQ

Which brand gained the most in ChatGPT recommendations this week? AskLab, up 21.5 DECA points to #5 in GEO, for the week of June 28, 2026 — though it nearly reverses its own drop the week before. Which category is most volatile right now? GEO — 23 of 103 brands moved ±10 ranks, for the third week running. SEO and Project Management also churned. Where is the #1 spot least safe? GEO and Influencer Marketing, where about 4–5 DECA points separate #1 from #2, followed by CRM (a 7-point gap). Did the CRM leader change again? Yes — Dynamics 365 Sales retook #1 from Zoho CRM (now #2), and HubSpot Sales Hub rebounded +16.0 to #3. Over three weeks the crown went Dynamics → Zoho → Dynamics. See the HubSpot vs Agentforce comparison. Is ChatGPT recommending more brands overall? The tracked set rose from 467 to 493 brand slots (+6%) this week, led by GEO (+12) and CRM (+10). Over four weeks it has drifted up (440 → 473 → 467 → 493) — GEO climbing steadily, most others oscillating — so read the level and trend, not the weekly tick. My category isn’t one of the 10 — can I still see who AI recommends in it? Yes. The index expands as recommendations in a category mature. Request a chart and DecaGEO will check whether ChatGPT recommends brands there and send the first chart. Requested categories are prioritized by demand. How should I read a single week’s move? As an observation, not a buying signal. This week is the clearest example yet: the new #1s in CRM and Marketing Automation, and two of GEO’s three surgers, all reversed within a week. Confirm with 2–3 weeks of trend before acting.

How we measure

DecaGEO runs a consistent set of recommendation prompts each week through ChatGPT (GPT-5.4) in the US region and records which brands are named and how prominently, across 10 software categories.

• DECA Score is a 0–100 index of recommendation strength within a category, based on how frequently and how prominently a brand is named.
• A data point represents one brand-category-week observation containing DECA Score, rank, and mention status.
• Model labels (e.g., GPT-5.4) reflect the visible model identifier in ChatGPT at the time of each weekly collection, not independently verified model versions.
• Limitations: Week-over-week counts partly reflect newly detected brands and may include re-aggregation noise. A single week’s change is an observation, not a trend. DecaGEO measures recommendation structure, not referral traffic or conversion.
