OpenAI’s revenues jumped from $3.7 billion in 2024 to $13.07 billion in 2025, with monthly sales hitting nearly $2 billion by year’s end. Those figures come from audited statements obtained by Ed Zitron and confirmed by the Financial Times. Rapid growth in user demand and enterprise deals drove that surge, but the headline numbers hide a much bigger story: costs are exploding even faster. R&D ate up $7.81 billion in 2024 and swelled to $19.18 billion in 2025. More than half of 2025’s R&D bill—$10.59 billion—went to Microsoft. On top of that, “cost of revenue,” basically the compute and infrastructure expenses for every query, climbed from $2.65 billion to $7.5 billion. Sales and marketing spending also jumped, from $1.11 billion to $5.73 billion. When you add it all up, operational losses soared from $8.78 billion in 2024 to $20.92 billion in 2025. OpenAI tells investors it aims for profits by 2030, but those raw loss numbers raise questions about burn rate and sustainability. Still, losses as a share of revenue fell, from 237 percent down to 160 percent, hinting that growth could eventually outpace costs—if they can keep scaling without even higher expenses.
