OpenAI Files for IPO After Anthropic

OpenAI 提交 IPO 申请，继 Anthropic 之后

OpenAI confidentially filed an S-1 with the SEC on Monday to start its IPO process; Anthropic filed the same type of document on June 1, and the post does not disclose executive compensation or business-risk details.

Why it matters: HKR-H/K/R all pass: OpenAI confidentially filed an S-1, and Anthropic filed on June 1, matching the top-band example of a foundation-model company IPO. Missing pay and risk details trim little from the event weight.
