DeepSeek, the Chinese AI company, landed at the top of Ramp's June trending software vendors list, the corporate spending platform reported this week. The ranking measures breakout growth relative to size across Ramp's customer base, and it shows American firms paying DeepSeek directly rather than running its open-weight models on their own hardware.
What the numbers actually say
Ramp tracks payments from roughly 70,000 US businesses, up about 40% from 50,000 at the start of the year. So a "trending" spot signals momentum, not market dominance. DeepSeek's actual business adoption sat at 0.1% by April, according to the Ramp report. Anthropic and OpenAI held 34.4% and 32.3% of the AI index in the same month. Ramp didn't release June market-share figures, which is the number that would tell you whether this is a real shift or a blip.
It's also not DeepSeek's first appearance. The company hit 0.3% adoption during a hype cycle in January 2025 before sliding back to 0.1%. That surge faded fast.
Why now
Pricing. In late May, DeepSeek made a 75% discount on its V4-Pro model permanent, per a Reuters report. Cached-input pricing dropped to a fraction of what the US labs charge for comparable workloads.
That math matters more as AI moves out of pilots and into daily operations. In agentic workflows, one user request can spawn dozens of model calls, tool invocations, and long-context passes. The token cost stops being a rounding error and becomes a budget line. Ramp economist Ara Kharazian, who tracks this for a living, posted on June 3 that he didn't expect American firms to touch DeepSeek at all. He called it the clearest sign yet that companies are hunting for cheaper alternatives, even willing to route data through Chinese servers to get there.
The part security people are flagging
Here's the catch nobody at the buying companies seems to be losing sleep over. These firms aren't self-hosting open weights, where data stays in-house. They're sending prompts, documents, and customer records straight to DeepSeek's infrastructure. OpenAI and Anthropic operate under US contracts and law. DeepSeek doesn't.
DeepSeek isn't alone on the list either. Fireworks AI, fal AI, and DeepInfra, all model-serving platforms, showed up too, along with GPU cloud provider Vast.ai. A cheaper-inference layer is forming around the premium US providers, whether or not DeepSeek itself sticks.
Ramp cautioned against reading too much into one month, which is the right call. The June list is a snapshot, not a verdict. The number to watch is whether DeepSeek holds a trending spot in the July report, and whether its adoption rate finally climbs past that stubborn 0.1%.
