OpenAI told investors in February its compute bill would be around $600bn. A July presentation puts it at $856bn.

OpenAI's July presentation shows its compute and infrastructure costs rising to $856bn by 2030, up from $600bn in February, while projected negative free cash flow improves to $278bn from $305bn. Revenue is forecasted to grow to $350bn by 2030, with much spending financed by partners rather than OpenAI itself.
