Anthropic hires Andrej Karpathy

Andrej Karpathy said on May 19 that he had joined Anthropic, adding one of the best-known researchers from OpenAI’s early years and Tesla’s AI group to the Claude maker’s staff. Anthropic said Karpathy will work on its pretraining team and will start a team focused on using Claude to accelerate pretraining research. Karpathy wrote on X that “the next few years at the frontier of LLMs will be especially formative” and that he was “very excited” to return to research and development. The announcement landed the same day Polymarket said it was launching prediction markets tied to private-company milestones through a data partnership with Nasdaq Private Market. ### What exactly did Karpathy and Anthropic say on May 19? Karpathy said on Tuesday that he was joining Anthropic after years in and around the top tier of AI labs and companies. CNBC reported that Anthropic said he starts this week and will be part of the pretraining team, which helps Claude models acquire core knowledge and capabilities. Anthropic said Karpathy will also begin a team focused on using Claude to speed up pretraining research, according to CNBC’s report of the company’s statement. Karpathy said on X that frontier large language model work over the next few years would be “especially formative” and that he wanted to get back to R&D. ### Why is Karpathy a notable hire in this rivalry? (cnbc.com) Karpathy co-founded OpenAI and later led Tesla’s computer vision work for Autopilot after leaving OpenAI in 2017, CNBC reported. Elon Musk described him in an email shown at the Musk v. Altman trial as “arguably the #2 guy in the world in computer vision,” CNBC said. (cnbc.com) TechCrunch also reported on May 19 that Karpathy joined Anthropic to work on pretraining. That places him inside one of the most compute-intensive and strategically important parts of a frontier-model company. ### Where does this land in Anthropic’s financing timeline? Anthropic said on February 12 that it raised $30 billion in Series G funding at a $380 billion post-money valuation. (cnbc.com) The company said the round was led by GIC and Coatue and included investors such as D. E. Shaw Ventures, Dragoneer, Founders Fund, ICONIQ and MGX. (techcrunch.com) Anthropic said in that announcement that its run-rate revenue had reached $14 billion and that Claude Code’s run-rate revenue was more than $2.5 billion. Those figures were part of the company’s own case to investors that demand for its models and coding products was expanding rapidly. Bloomberg reported on May 12 that Anthropic was in early talks to raise at least $30 billion in fresh financing at a $900 billion valuation. (anthropic.com) Anthropic declined to comment to Bloomberg, according to that report. ### What did Polymarket launch the same day? Polymarket said on May 19 that it launched prediction markets tied to private-company performance and milestones. (anthropic.com) The company said Nasdaq Private Market would serve as the resolution data provider under an exclusive agreement. (bloomberg.com) Polymarket said those markets may cover valuation milestones, IPO timing and secondary-market activity. Reuters reported the launch as a first for the prediction-market sector’s push into private-company events. ### Did the two announcements get linked online? (businesswire.com) Social-media users linked Karpathy’s move to Anthropic with fresh speculation about the company’s valuation and competitive position against OpenAI, according to the source briefing and contemporaneous posts cited there. Those posts were commentary, not company statements, and neither Anthropic nor Karpathy said the hire was tied to any financing process. (businesswire.com) Polymarket’s launch gave traders a new venue to bet on private-company milestones on the same day the Karpathy news spread. The company said Nasdaq Private Market data would determine how those contracts resolve. ### What comes next from here? This week is Karpathy’s stated start date at Anthropic, according to the company’s comments reported by CNBC. (bloomberg.com) Any new public detail on his remit is most likely to come from Anthropic statements, Karpathy’s X account, or future company product and research updates. (cnbc.com) (businesswire.com)
