Microsoft steers sales teams away from OpenAI and Anthropic
Microsoft has instructed its sales force to promote its in-house AI models over those of partners OpenAI and Anthropic, signalling a decisive shift in the cloud market as the company moves to justify $357 billion in AI investments.
At an internal strategy meeting on Tuesday, Microsoft executives told the sales force to actively run down the capabilities of OpenAI, Google, and Anthropic. The directive marks a sharp pivot for a company that spent years and vast sums building its AI products on top of those exact partners.
The pitch centres on Microsoft’s homegrown MAI models, which executives argue are cheaper, more efficient, and better integrated. “Everyone else is selling parts. We’re selling the full end-to-end system. That’s the story that we all need to get out there and tell in FY27,” executive vice president Jay Parikh told the room.
Executive vice president Jacob Andreou went further, instructing staff to pitch Microsoft’s Copilot directly against Anthropic’s Claude. He claimed Claude is slower and less accurate in office applications while lacking security integrations. Notably, Claude remains embedded in Copilot, meaning salespeople are being coached to criticise an engine the company is still actively shipping.
This shift stems from a structural change in April, when Microsoft and OpenAI dropped their exclusivity clause. Free to sell to Microsoft’s rivals, OpenAI quickly struck a deal to offer its models through Amazon Web Services. Once a partner can supply your competitors, the rationale for promoting their technology collapses.
Anthropic has become the primary target for cost reduction. Microsoft’s AI chief has stated a desire to eliminate what the company pays Anthropic, and internal engineers have quietly stopped using Anthropic’s Claude Code tools. Replacing external models with cheaper in-house alternatives is the most straightforward way to cut those bills.
The investor calculus
For investors, the sales meeting is an attempt to reframe a $357 billion AI capital spending drawdown that has drawn visible scepticism. By convincing customers that in-house models are not just cheaper but technically superior, Microsoft is arguing that its massive infrastructure investments have yielded proprietary assets rather than just a reliance on resold third-party technology.
Enterprise customers, however, may prove resistant to the new messaging. Claude has become the default choice in AI coding tools, and buyers typically rely on independent benchmarks rather than vendor presentations. For businesses currently navigating complex AI procurement, the message from Redmond introduces a new layer of vendor volatility.
Microsoft currently maintains a three-way hedge: it holds a large OpenAI stake, ships Anthropic’s models, and sells its own MAI line against both. But Tuesday’s kickoff made clear which of those three the company intends to prioritise as the market matures. Neither Microsoft nor Anthropic commented on the developments.
