AI Rivalries Intensify as OpenAI Battles Anthropic for Enterprise Clients and Amazon Takes On Perplexity's Shopping Agent
Competition between OpenAI and Anthropic has expanded beyond model performance into enterprise adoption and business models. Anthropic signed a multiyear, $200 million partnership with Snowflake in December 2025, while OpenAI is leveraging ChatGPT's vast user base to expand in the enterprise market. Control of corporate workflows and advertising gateways could shape generative AI revenue and determine which platforms dominate.
At Super Bowl LX on February 8, 2026, Anthropic ran two advertisements mocking OpenAI's introduction of ads to ChatGPT, escalating their battle of brands. On March 9, a federal court in San Francisco granted Amazon a preliminary injunction barring Perplexity's Comet agent from logging into Amazon to shop on users' behalf. The court found that Amazon had presented compelling evidence of unauthorized access.

The history behind this eventAnthropic Gains on OpenAI in Enterprise Adoption as AI Competition Intensifies
OpenAI has long led the enterprise generative AI market, but Anthropic is expanding its corporate customer base through Claude. Payments company Ramp tracks adoption using U.S. corporate spending data, which indicates that businesses are diversifying vendor risk and that competition among model providers is extending beyond technical performance to commercial adoption.
Ramp data showed that Anthropic’s adoption among U.S. businesses rose sharply in March, while the latest reports said it surpassed OpenAI for the first time. OpenAI had previously remained the leader with a 35% adoption rate, but its enterprise growth had begun to level off. The data did not disclose purchasing amounts, but indicated that the gap between the two companies was narrowing rapidly.
