Microsoft Discloses $24.1 Billion In OpenAI Sales. That Is 70 Percent Of Its AI Revenue. The Concentration Is Striking.
Microsoft booked $24.1 billion in OpenAI-related sales in its fiscal year ended June, likely about 70 percent of its total AI revenue. Bloomberg estimates Microsoft's AI business took in roughly $34 billion over those 12 months. Microsoft also recorded roughly $51 billion in commercial bookings last quarter. OpenAI's contribution remains below 10 percent of Microsoft's overall revenue.
This demonstrates the principle of revenue concentration risk. The mechanism is single-vendor dependency. When one partner generates 70 percent of a division's revenue, that division is not really a business. It is a reseller with better branding. Investors now have a concrete anchor for Microsoft's AI business, which is useful, but the number also reveals how little diversification has actually occurred.
Microsoft, which disclosed these figures after rarely providing full AI revenue numbers. Bloomberg produced the $34 billion total AI revenue estimate based on the new OpenAI disclosure.
- Open a spreadsheet and list every AI tool or service you pay for personally or professionally.
- Next to each, write the monthly cost and what percentage of your total AI spending it represents.
- If any single tool exceeds 50 percent of your total AI budget, identify one alternative provider for that function. You should never let one vendor dominate your spending that heavily. Diversification is not optional. It is risk management.
