Britain's competition watchdog said on Thursday it had started an investigation into whether Amazon 's partnership with AI startup Anthropic raised competition, days after it began a similar probe on Alphabet 's collaboration with the startup. "Amazon's collaboration with Anthropic does not raise any competition concerns or meet the CMA 's own threshold for review," an Amazon spokesperson said in an emailed statement. "Amazon holds no board seat nor decision-making power at Anthropic, and Anthropic is free to work with any other provider (and indeed has multiple partners)," the spokesperson said, echoing comments from an Anthropic spokesperson. "Our strategic partnerships and investor relationships do not diminish our corporate governance independence or our freedom to partner with others," the Anthropic spokesperson said. "Late in July, CMA launched a probe into Google parent Alphabet's partnership with Anthropic, which was co-founded by former OpenAI executives and siblings Dario and Daniela Amodei.
