OpenAI is racing to secure investor commitments before rival Anthropic's expected public market debut in mid-November.[^1]

The company is raising approximately $30 billion in this round. SoftBank Group, Abu Dhabi-based MGX and other existing backers are set to participate.[^2]

OpenAI aims to finalise the round before Anthropic releases public disclosures. This timeline would prevent investors from comparing the two businesses directly side by side.[^3]

The two firms use differing accounting practices for contract revenue. OpenAI deducts partner shares before booking revenue. Anthropic has accused OpenAI of counting the full face value of contracts sold through cloud providers.[^4]

OpenAI's previous funding round, closed in March, carried a $122 billion valuation. That round was anchored by Amazon, Nvidia and SoftBank.[^5]

Internal emails reviewed by Business Insider show Amazon AWS is expected to receive roughly $5 billion in Nvidia GB300 server racks at US facilities prior to final deployment.[^6]
