AI company Anthropic is struggling to secure sufficient computing power from cloud service providers such as AWS, Google, and Microsoft, as these giants increasingly view it as a competitor, according to an S-1 filing leaked to The Wall Street Journal. The company plans an IPO in November, with cloud contract spending potentially exceeding $750 billion. The filing also shows that Anthropic reported a net loss of $80.7 billion on revenue of $16.3 billion in the first half of the year; third-quarter revenue jumped to $16.8 billion, a 45% increase quarter-over-quarter.
