Sen. Elizabeth Warren sent a letter to Anthropic CEO Dario Amodei on Tuesday, demanding detailed answers to concerns raised in the company’s recent initial public offering filing. The Massachusetts Democrat requested exhaustive responses by November 3 regarding how the firm will prevent its technology from causing existential threats to humanity. Her inquiry also covers Anthropic’s relationships with partners like Amazon and Broadcom, as well as its strategy for justifying a valuation that could reach $2 trillion. Anthropic did not immediately respond to requests for comment.

Background

• Anthropic is preparing for a potential $100 billion offering, which could become the largest IPO in history, with a filing suggesting a public debut as soon as the week before Thanksgiving.
• The company’s filing noted that AI might facilitate the creation of novel biological weapons and disrupt global political stability, while also claiming it could help cure major diseases.
• Warren has previously urged the Securities and Exchange Commission to delay SpaceX’s June IPO due to valuation and governance concerns, though that offering proceeded as planned.
• The senator has met with Amodei earlier this year and is part of a group of lawmakers advocating for slower development of advanced AI to allow for stronger regulation.
