Claude vs ChatGPT: which one Latin American companies pay for (2026)

November 13, 2026

In October 2026, 24.7% of companies in Latin America paid Anthropic, the company behind Claude, and 20.1% paid OpenAI, the company behind ChatGPT. Beyond those two, no LLM-focused AI company tops 2.9% of companies.

xAI's Grok went from 0.41% to 1.6% in 12 months and now ranks fourth, ahead of OpenRouter (0.93%). Google, with Gemini, has 2.9% of companies but takes only 0.34% of AI spend.

The figures come from Clara's AI Monitor, which tracks month by month how much companies pay each AI vendor with Clara's corporate card. It covers more than 45,000 companies in Brazil, Mexico and Colombia.

Key findings

  • Anthropic takes 57.6% of everything companies in the region spend on AI, and OpenAI, 19.4%.
  • Combined, LLM-focused AI companies take 80.4% of AI spend.
  • Grok went from 0.41% to 1.6% of companies in 12 months.
  • OpenRouter, which resells models from several vendors, has 0.93% of companies and 1.4% of spend.

Claude or ChatGPT: which one do companies pay for?

Both, on a scale no other LLM-focused AI company comes close to. In October 2026, 24.7% of companies in the region paid Anthropic and 20.1% paid OpenAI. By spend, though, Anthropic pulls far ahead: it takes 57.6% of AI spend, against 19.4% for OpenAI.

A year earlier, the picture was different: in October 2025, 3.1% of companies paid Anthropic, and 18.5% paid OpenAI.

The share of companies paying any LLM-focused AI company went from 19.4% to 34% in 12 months (+14.6 points), and the group's share of AI spend rose from 56.9% to 80.4%.

Who comes after Claude and ChatGPT?

Google, xAI and OpenRouter, none with more than 2.9% of companies. Google, which owns Gemini, ranks third by number of companies (2.9%) but takes 0.34% of spend. xAI's Grok grew faster: it went from 0.41% to 1.6% in 12 months and ranked ahead of OpenRouter in October.

OpenRouter is a different case: it gives access to models from several vendors, including Anthropic and OpenAI, through a single account. Part of what companies pay it ends up with Claude and ChatGPT. It went from 0.16% to 0.93% of companies in 12 months (+0.77 points).

What about Perplexity?

Perplexity, the AI-powered answer engine, is paid for by 0.41% of companies in the region, practically the same as a year earlier (0.37%).

What about Brazil, Mexico and Colombia?

Anthropic and OpenAI also lead in all three countries. Google ranks third in Brazil (2.9%), Mexico (2.7%) and Colombia (4.1%). Grok has 1.8% of companies in Brazil, 1.3% in Mexico and 1.7% in Colombia. In Colombia, Perplexity ranks fifth, with 0.68%.

Combined, LLM-focused AI companies are paid for by 33.3% of companies in Brazil, 33.5% in Mexico and 39% in Colombia.
