Microsoft and Meta Cut Internal Claude Usage as Costs Balloon

According to The Information, two major Anthropic customers, Microsoft and Meta, are working to steer employees away from Claude, largely due to the mounting pressure of soaring Claude bills. Multiple posters (@RihardJarc, @Hesamation) relayed the news, noting both companies are pushing their own tools as alternatives: thanks to its OpenAI partnership, Microsoft's internal use of OpenAI models comes at no extra cost.

Confirmed

Per The Information, Microsoft has cut internal Claude spending by more than a third, and Meta is also reducing Claude costs (relayed by @RihardJarc).
The cuts are driven by cost: Claude bills have ballooned, and both companies are shifting toward promoting their own in-house tools (@Hesamation).

Unconfirmed

More specific figures from @ns123abc are unverified claims: Microsoft's per-employee monthly token budget cut from $100,000 to $10,000; the poster also said Anthropic's IPO prospectus shows highly concentrated revenue with two customers accounting for 25%, and claims like "Meta users halved" are all flagged as unofficial—treat with caution.

Why it matters

Big customers tightening usage directly hits Anthropic's revenue outlook, and with its IPO in progress, customer concentration and churn risk have become investor focal points. @RihardJarc argues Meta's willingness to cut Claude spending also reflects a broader belt-tightening trend in enterprise AI budgets.
