The Deceleration

The Deceleration

Gartner's contract-value growth did not collapse in 2025; it decelerated on a schedule — and the fact that matters most about that schedule is where the weakness spread. Gartner's U.S. federal Insights contract value fell from about $225 million in March 2025 to $114 million in March 2026 (roughly halved, ~250bps of the CV-growth drag), but the weakness did not stay federal: GBS wallet retention — a channel with almost no federal exposure — rolled to 98.6% in the fourth quarter of 2025, ex-federal CV growth still decelerated to 3.5% by the first quarter of 2026, and Consulting's labor-based revenue fell 5% in 2025 before total Consulting revenue dropped 15% to $119 million in the first quarter of 2026, a second non-federal, non-Insights line showing the same client decision-hesitation. [1] [2]

The stakes sit in what "did not stay federal" costs the cyclical read. The roughly 6.5-point swing in GTS FX-neutral CV growth on a roughly $3.9 billion book is about $250 million of annualized CV growth foregone, while federal is only about 4% of contract value and roughly 250 basis points of the first-quarter-2026 drag — so a self-lapping-federal story cannot by itself account for GBS wallet retention at 98.6% or Consulting revenue down 15% in the first quarter. The clean falsifier prints in the second quarter of 2026, the first period fully past the DOGE shock: GTS wallet retention back above 100% and ex-federal CV growth holding would confirm the cyclical read. Against it, GTS wallet retention ticked from 96.0% to 96.5% — its first sequential improvement — and management calls the federal book "rebaselined" [3] and the Consulting softness "more timing-related than structural" [4]. One quarter is not a trend.

This is the dated, quarter-level test of whether the stall documented in The Subscription Engine is a cyclical air-pocket or the leading edge of erosion. The evidence reads cyclical in origin and broadening in reach, with the timing of a recovery still a management assertion rather than a trend.

A datable deceleration

The quarterly record turns the annual snapshot into a slope. GTS — the larger Insights channel, more than three-quarters of contract value — grew 6.5% on a foreign-currency-neutral basis in the fourth quarter of 2024, then decelerated every quarter of 2025: 5.5%, 3.6%, 1.7%, and roughly zero by year-end, before ticking to 0.4% in the first quarter of 2026. Global Business Sales (GBS) traced the same arc one channel over, from 12.6% to 3.5%.

The slope is smooth and continuous, not a cliff — the signature of a book of twelve-month-plus subscriptions repricing gradually as renewals come due, rather than a sudden wave of cancellations. That shape matters: it is what a demand shock looks like when it filters through a contract base with a long lag, and it is also what the early innings of a structural decline would look like. The shape alone does not separate the two. The composition does.

The federal book, quarter by quarter

The single largest identifiable cause is precise and dateable. Management has said the US federal disruption — procurement changes tied to the new administration's DOGE initiative — "really didn't start feeling" until March 2025; January and February were "seminormal," and the impact ran "March and April and then forward from there." [7] The federal book was already draining by the first quarter: Gartner held $225M of US federal contract value at March 31, 2025, and of the roughly 40% of federal contracts that came up for renewal that quarter, dollar retention was "almost 50%." [8]

Sources: Q1 2025 call ($225M, Mar 2025) [9]; FY2025 Annual Report ($126.0M, Dec 2025) [10]; Q1 2026 call ($114M, Mar 2026) [11].

By December 31, 2025 the federal Insights book had fallen to approximately $126.0M, with less than half of the December 2024 balance retained during the year. [12] It slipped again to about $114M by March 2026. [13] Federal is only about 4% of total contract value, but because it was a book actively shrinking rather than merely growing slower, it carried roughly a 250-basis-point headwind to the headline CV growth rate in the first quarter of 2026. [14]

The cyclical read rests on two claims a bull can point to. Management says the federal business is now "rebaselined" and expects it to be "flat in 2026 and grow from there." [15] And the drain lapped in the second quarter of 2026 — the first period compared against a base already hit by DOGE. If the federal book holds near $114M, its drag on the growth rate mechanically fades.

The rollover, and where it broadened

Wallet retention — the trailing measure of whether the retained base spent more or less than a year earlier — is the cleaner fingerprint, because it isolates dollars-per-account from new-logo activity. GTS wallet retention crossed below the 100% net-expansion line in the second quarter of 2025 (99.3%, from 101.1%), bottomed at 96.0% in the fourth quarter, and edged up to 96.5% in the first quarter of 2026. GBS held above 100% two quarters longer, breaking the line only in the fourth quarter of 2025 (98.6%).

The staggered timing is the most important detail on this chart. GBS sells to functional leaders — HR, supply chain, finance, marketing, legal — and carries almost no federal exposure, yet its wallet retention still rolled over, only later. Management noted that even excluding federal, GBS wallet retention was "over 100%" in the fourth quarter of 2025, which places the GBS softness largely outside the government story. [18] The caution, in other words, started with technology buyers under a specific policy shock and spread to functional buyers under a broader budget one — the same widening the consulting business showed (Conferences and Consulting). That breadth is what keeps a purely federal, self-lapping interpretation from fully accounting for the deceleration.

The capacity that is now shrinking

The subtler constraint sits in the salesforce. Gartner's growth arithmetic is quota-bearing headcount multiplied by per-rep productivity, and both turned against it. GTS quota-bearing headcount grew 4.5% year-over-year in the fourth quarter of 2024; by the first quarter of 2026 it was falling 3.3%. Total sales headcount was down 3.4%.

Sources: 4Q25 earnings supplement, Insights Metrics [19]; 1Q26 earnings supplement, Insights Metrics [20].

This is partly by design and partly a limit on the recovery. Management's stated model is that "quota-bearing headcount growth should grow roughly 300 basis points slower than our expected CV growth," off a 2025 base. [21] With CV growth near 1%, that formula produces a shrinking salesforce almost mechanically — headcount follows growth down and will follow it back up only with a lag. It also means the near-term reacceleration cannot be led by adding capacity; it has to come from productivity and wallet retention normalizing on a leaner base. Per-rep quarterly productivity was still negative in the first quarter of 2026, so that normalization is a forecast, not yet a fact.

The faint upturn, and what would confirm it

The first quarter of 2026 is where management's cyclical case gets its first supporting data — modestly. Total contract value reached $5.3B, up 1.0% FX-neutral, a fractional acceleration from the fourth quarter's 0.9%; growth excluding federal was 3.5%; and Gartner booked more than $200M of new business in a seasonally light quarter. [22]

Against that, the printed acceleration is fractions of a point, and the forward path is management's assertion. On the first-quarter call, executives said they "expect CV growth to accelerate over the course of 2026" repeatedly, across both the federal recovery and the commercial base. [24] A year earlier, at the same podium, they were equally confident that they were "well-positioned to accelerate growth" once the environment normalized — and the deceleration ran for four more quarters. [25] The reacceleration is unproven until the trailing metrics turn, and a short list of falsifiable signals will mark which way it breaks.

Sources: metrics defined in the quarterly earnings supplements [26]; federal framing per management [27].

The weight of the quarter-by-quarter evidence is that the deceleration is cyclical in origin — a dateable federal shock, layered onto a broader budget caution that also touched functional buyers and consulting — and that it reached a trough around the turn of 2026. What it does not yet show is the recovery. The first-quarter upturn is real but faint, the salesforce is contracting into the slowdown by management's own formula, and the reacceleration is a forecast that the same voices made, and missed, a year ago. The second quarter of 2026 — the first clean read after the federal lap — is the next place the numbers either confirm the trough or extend it.
