Market Chatter: OpenAI Accelerates Fundraising Efforts Ahead of Anthropic's Expected November IPO

05:05 AM EDT, 10/20/2026 (MT Newswires) -- OpenAI is racing to secure commitments for a roughly $30 billion funding round at a valuation exceeding $1.4 trillion ahead of rival Anthropic's expected mid-November initial public offering, Reuters reported Monday, citing people familiar with the matter. Existing OpenAI backers, including SoftBank and Abu Dhabi-based MGX, are in talks to join the round, the unnamed sources told the news agency. The ChatGPT maker aims to complete the fundraising before Claude maker Anthropic's expected IPO disclosures prompt comparisons between the two AI developers, according to the report. OpenAI didn't immediately respond to MT Newswires' request for comment. (Market Chatter news is derived from conversations with market professionals globally.
