Microsoft Faces a Twin Reckoning: Anthropic's Office Push and a Looming Transceiver Ban

Microsoft's AI story is being tested on two fronts at once — one commercial, one political — and neither is fully within the company's control. On the product side, Anthropic has moved into Microsoft's home turf with spreadsheet and whiteboard tools aimed squarely at everyday Office workflows. On the supply side, Microsoft has asked the Trump administration to shelve planned import restrictions on new Chinese optical transceivers, warning that the curbs would complicate the build-out of American AI data centres, according to Reuters. The proposed limit is not yet a final rule.

The market's reaction to the first threat was swift. Microsoft shares fell 1.8% yesterday, the day Anthropic unveiled Claude Sheets and Claude Whiteboards — applications built for spreadsheet work and collaborative brainstorming, with Sheets able to generate and edit tables by AI and save Excel files. Both tools were available in beta to paying users, giving the rival an early foothold in routine work.

Goldman Backs the Strategy, BNP Lifts the Target

Analyst sentiment, by contrast, remains constructive. Goldman Sachs, after talks with Microsoft executives in recent weeks, argues that enterprises increasingly treat AI platforms as essential and that the company's decisions of recent years are starting to pay off — provided Microsoft can convert that relevance into extra revenue. BNP Paribas reaffirmed its buy recommendation today with a price target of $549; analyst Stefan Slowinski sees long-term room for Azure price increases, though Microsoft executives have said higher prices only take effect once existing contracts expire.

The number that matters most in settling the argument is revenue growth in the Microsoft 365 commercial cloud, where it becomes visible whether Microsoft can monetise its installed base more deeply despite new alternatives. In the first quarter of fiscal 2027, that revenue rose 17% as reported, while the count of Copilot customers using credits climbed 75% from the prior quarter — a combination that points to broader uptake of consumption-based offerings, so long as it hardens into recurring customer spending.

Azure supplies the demand-side evidence. Revenue reached $33.2 billion in the first quarter of fiscal 2027, up 48% year on year, and Microsoft guides to 49–50% growth in constant currency for the current quarter. Daily Copilot usage also picked up recently, with larger customers widening their deployments.

Should investors sell immediately? Or is it worth buying Microsoft?

Anthropic Is Both Rival and Tenant

The competitive picture is more tangled than a simple share shift. Anthropic's product chief Nicholas Lin has described Claude Sheets as still basic and unsuited to advanced financial models — leaving Microsoft room to defend complex enterprise work if customers prize feature depth over the novelty of new AI tools. And the relationship has a financial reverse side: in November 2025, Anthropic committed to buying $30 billion of Azure computing capacity over time, letting Microsoft profit as an infrastructure partner even while the two companies compete in office software.

The bear case begins where AI usage grows but customers cap their extra spending — testing new tools on the side while holding back what they will pay for Copilot, particularly if Microsoft can only push through higher prices with a lag. Against that delayed revenue potential sit heavy outlays: capital expenditure including finance leases hit $45.2 billion in the first quarter of fiscal 2027, and finance chief Amy Hood expects more than $50 billion in the following quarter.

A Supply Chain Warning and a Leaner Landlord

Microsoft's appeal to Washington adds a second variable: whether Chinese components remain available for US data centres. The company is trying to head off a procurement risk at the same time as it takes a more cautious line on individual external infrastructure projects — and the two moves have to fit together for a more selective investment policy to become an advantage.

Bloomberg reported on Friday that Microsoft is letting its agreement to rent AI computing capacity at Oracle lapse after declining to renew. On Thursday, it also reported tighter scrutiny of certain data-centre projects with Nebius, IREN and Nscale, with Microsoft pulling back from ventures it deems risky while weighing further deals with specialised cloud providers. Reuters reported that Microsoft likewise declined an option to more than double an existing capacity agreement with Nscale for a Texas data centre; Nscale's listing documents put its power agreements with Microsoft at up to roughly $43.8 billion through December 2033, excluding optional extensions. Oracle said after the lapse report that demand for its AI infrastructure remains strong.

The favourable scenario keeps large capacity commitments alongside stricter project selection: Microsoft sheds extra obligations yet still secures enough infrastructure for a growing cloud business. The genuine risk is that import hurdles and a more restrained contracting strategy bite at the same time, leaving fewer suitable fallbacks and forcing project choices under harder conditions. Dropping expansions would then hurt more if that capacity is needed elsewhere.

What to Watch

The next political catalyst is how the US government proceeds on the transceiver restrictions; a final rule would give Microsoft's supply-chain warning more weight, while abandoning the curbs would defuse the procurement risk it has flagged. On the commercial side, the annual shareholder meeting on 8 December offers the nearest fixed date, with attention on management commentary about enterprise willingness to pay and the rollout of consumption-based billing. Azure's roaring growth supplies the economic incentive — access to components and dependable projects will determine how much business Microsoft can build from it.
