New spending data from Ramp reveals a possible trend: end user AI adoption may be hitting its first growth slow down.
The AI adoption party might be slowing down—at least temporarily. Fresh data from Ramp’s AI Index suggests that the meteoric rise in business AI spending might be showing signs of deceleration, raising questions about whether we’re witnessing market maturation or beginning to hit a potential adoption ceiling:
The numbers tell a nuanced story. While overall AI penetration among U.S. businesses has reached an incredible 41.7% as of April 2025, the growth trajectory has flattened since late 2024. Even more telling: OpenAI, despite maintaining market leadership at 33.9%, has actually seemingly lost some ground from its peak share levels.
But it’s just one data point, albeit across many Ramp customers.
The Deceleration Evidence
Ramp’s card spend data reveals several concerning trends that suggest the AI adoption curve is indeed slowing:
The growth rate from Q4 2024 to Q1 2025 was significantly lower than previous quarters, even accounting for typical seasonal variations in enterprise spending. More importantly, the gap between OpenAI’s trajectory and overall market growth indicates that even the category leader is struggling to maintain momentum.
Perhaps most significantly, we’re not seeing the explosive growth in new providers that characterized the earlier phases of the market. While Anthropic has steadily climbed to 9%, Google remains stuck at 2.3%, and newer entrants like xAI and DeepSeek are showing minimal traction despite significant media attention.
Why the Slowdown May Be Real
Several structural factors suggest this isn’t just a temporary pause:
- Implementation complexity has caught up with enthusiasm. The businesses that adopted AI quickly were typically tech-savvy organizations with straightforward use cases. As adoption moves to more traditional enterprises and more complex applications, the time from evaluation to implementation has stretched considerably.
- ROI scrutiny is intensifying. CFOs who initially approved AI experiments are now demanding concrete business outcomes. The shift from “innovation budget” to “operational budget” means AI tools must compete directly with established software investments—and many aren’t winning those comparisons yet.
- Skills bottlenecks are widening. Beyond basic ChatGPT usage, effective AI implementation requires specialized expertise that’s in critically short supply. Companies are discovering that hiring AI talent or upskilling existing teams takes much longer than anticipated.
- Integration challenges are mounting. Moving from AI pilots to production-grade implementations requires solving hard technical problems around data pipelines, security, compliance, and workflow integration. Many organizations are stuck in “pilot purgatory”—running successful experiments but unable to scale them.
Why the Slowdown Might Be Illusory
Enterprise Sales Cycles Are Finally Kicking In
The most compelling explanation for the apparent plateau has nothing to do with demand and everything to do with procurement realities. The organizations driving AI adoption today are fundamentally different from those who adopted in 2023.
Early adopters were predominantly tech companies, startups, and digital-native businesses with short decision cycles and high risk tolerance. They could implement AI tools in weeks, not months. But as we move into mainstream enterprise adoption, we’re dealing with Fortune 500 companies, regulated industries, and government agencies—organizations where a 12-18 month procurement cycle is considered fast.
What looks like slowing adoption may simply be the natural lag between enterprise interest (which peaked in late 2023) and enterprise implementation (which is happening now). The spending data captures signatures and payments, not the decision-making process that began quarters earlier.
Budget Cycles Are Misaligned
Most large enterprises finalized their 2025 technology budgets in Q3 2024, when AI was still viewed as experimental rather than operational. Many organizations that wanted to invest in AI found themselves constrained by budget allocations made before AI’s business value became clear.
The real test will come in 2026 budget planning cycles, where AI is likely to receive significantly larger allocations. Current spending patterns may reflect budget constraints rather than demand softening.
The Hidden Enterprise Pipeline
Card spend data, while valuable, captures only a portion of enterprise AI investment. Large-scale AI implementations often involve:
- Multi-year enterprise agreements that don’t show up in monthly spending data
- Professional services and consulting engagements billed separately
- Internal development costs that never appear in vendor payments
- Pilot programs funded through different budget categories
The enterprises now implementing AI are doing so at much larger scale than early adopters, but through procurement vehicles that may not be fully reflected in Ramp’s data.
Platform Consolidation Is Masking Growth
The apparent market share shifts—particularly OpenAI’s slight market share decline—might reflect platform consolidation rather than overall market softening. Enterprises are increasingly choosing integrated AI platforms over point solutions, which could reduce the number of distinct AI vendor relationships while increasing total AI spending.
Microsoft’s Copilot integration, Google’s Workspace AI features, and even Salesforce’s Einstein capabilities allow companies to increase AI usage without adding new vendors. This consolidation would appear as slowing adoption in card spend data (if it shows up on cards at all) while actually representing accelerated implementation.

That adoption is just getting going, vs end users buying direct subscriptions to the AI model leaders.
The Anthropic Exception
One bright spot in the data is Anthropic’s continued growth while the overall market slows. Their steady climb to 9% market share suggests that enterprise buyers are becoming more sophisticated, choosing AI providers based on specific capabilities rather than brand recognition alone.
What This Means for the Market
If Ramp’s data reflects a genuine slowdown rather than seasonal variation or just a bump, the implications are significant:
- The low-hanging fruit may be picked. Future AI adoption will require solving harder problems for more conservative buyers. This favors companies with strong enterprise sales capabilities over those relying on viral adoption.
- Price pressure is coming. Slower growth typically leads to increased competition on price, especially as venture funding becomes more selective and companies need to demonstrate sustainable unit economics.
- Feature wars are just beginning. Generic AI capabilities are being commoditized. The winners will be those that solve specific, measurable business problems rather than offering general-purpose AI tools.
- Services opportunities are expanding. If implementation complexity is the primary barrier to adoption, there’s significant opportunity in professional services, training, and consulting around AI integration.
The Bottom Line
Ramp’s latest data suggests we may be entering a new phase of AI adoption—one characterized by more careful evaluation, longer implementation timelines, and greater emphasis on measurable outcomes. This isn’t necessarily bad news for the AI market, but it does represent a significant shift from the explosive growth patterns of 2023 and early 2024.
The companies that adapt to this new reality—focusing on solving specific business problems rather than chasing AI hype—are likely to emerge stronger when growth accelerates again. Those that don’t may find themselves casualties of a more mature, more demanding market.
The AI revolution isn’t over, it’s just begun. But it’s growing up.
