A few hours after I posted about Anthropic's IPO filing this morning, they rolled out an office suite. Claude Sheets and Claude Whiteboards are in beta on paid plans, Claude Data (renamed from Claude Dashboards) is now generally available, and Claude Meetings is in beta for Team and Enterprise customers, starting with Google Meet. Meetings joins your calls as a participant.
The timing is what gets me. Microsoft is one of the investors in Anthropic's proposed up-to-$26 billion private placement tied to the IPO, alongside Google. Bloomberg points out this puts Anthropic in sharper competition with two of its own backers.
Microsoft shares fell today. They were down as much as 3.45% from yesterday's close at the session low of $526.37, then pared losses to close at $532.81, down 2.27%.
The broader market was also weak after a hotter-than-expected October CPI and Fed Governor Waller's talk of a possible half-point December hike, so not all of that is Anthropic.
What I find telling is that Anthropic's product lead, Nicholas Lin, told Bloomberg that Sheets is still a relatively basic product, built for neither sophisticated financial modeling nor advanced enterprise workloads, and that existing spreadsheet integrations will remain more effective there.
So the company itself is downplaying the product, and Excel's parent still took a sharp midday leg down when the tools were announced. To me that says the market is pricing where Claude goes next rather than what Sheets does today. I'd love to know how Microsoft and Google are thinking about that cornerstone check this week.
