According to TechCrunch, Microsoft disclosed in regulatory filings on 10 28 that for the quarter ending 9 30 (Microsoft's 2027 fiscal year first quarter), revenue from its commercial arrangements with OpenAI (including revenue sharing) was 100 billion USD, accounting for approximately 11% of the total quarterly revenue of 923 billion USD.
Confidence: Medium (50) · Event Time 2026-10-28
Rationale
- This is the first time Microsoft has provided a quarterly figure for revenue from OpenAI, indicating that although the two companies compete for the same enterprise customers, they remain deeply financially intertwined. TechCrunch reported that Microsoft's full-year 2026 fiscal year revenue from OpenAI was 241 billion USD, which annualizes to approximately 400 billion USD based on the latest quarter.
- The same filing shows that OpenAI's receivables owed to Microsoft rose from 60 billion USD at the end of 6 to 72 billion USD at the end of 9; Microsoft's stake in OpenAI decreased from approximately 25% to 24%, with no reason provided.
- Under the agreement from 4 2026, OpenAI will continue to share revenue with Microsoft until 2030 (with a cap), while also being able to partner with other cloud providers.
Usage
- None.
Risks
- Only TechCrunch's report was reviewed; Microsoft's regulatory filings were not directly verified.
- It is unclear how much of the 100 billion USD comes from revenue sharing versus Azure cloud services; the frequently cited claim that "OpenAI shares 20% of its revenue with Microsoft" has not been publicly confirmed by either party.
