Silver Lake is in talks to take Workday, the cloud-based HR and finance software company, private in a deal that would value it at roughly $43bn, according to a Reuters report.

If it comes off, it would rank among the largest software buyouts ever struck, and a rare vote of confidence in a corner of the industry the public market has spent the year souring on.

The talks are, for now, exactly that. Reuters, which broke the story, described the discussions as ongoing, and neither Silver Lake nor Workday has commented.

No competing bidders have surfaced, and nothing has been signed, so the $43bn figure should be read as a reported valuation rather than a done deal.

Investors, however, did not wait for the fine print. Workday shares jumped about 25% on the report before trading was halted, according to CNBC, a leap that says as much about how far the stock had already fallen as about the deal itself.

And it had fallen a long way. Workday was down roughly 15% for the year and more than 40% off its 2024 peak before the news broke, a slide that reflects a growing unease about whether seat-based software subscriptions can hold their value in the age of AI.

That unease is the whole story. Workday charges, broadly, per employee who uses its software, which is a wonderful model when companies are hiring and a nervous one when they are automating.

If AI agents start doing the work that human seats used to, the logic of paying by the head starts to wobble.

This is the fear that has been chewing through SaaS valuations all year, the suspicion that AI is quietly eating software as a service from the inside. Whether that is a genuine reckoning or a bout of narrative-driven panic is the argument the whole sector is currently having with itself.

Silver Lake, evidently, has a view. Private-equity firms tend to buy things the stock market has fallen out of love with, and a profitable, sticky, cash-generative enterprise-software company trading at a heavy discount to its recent highs is close to their platonic ideal of a target.

There is precedent for the enthusiasm. Silver Lake has spent years hoovering up software assets, and it is far from alone in betting that the AI panic around enterprise software is overdone rather than terminal.

Other investors are making the same wager in public. European growth investor Main Capital recently raised a €5.25bn war chest explicitly betting against the AI panic in enterprise software, a reminder that not everyone thinks the category is doomed.

The bull case is straightforward enough. Workday sits at the core of how large organisations run payroll, hiring and finance, the sort of software that is agonising to rip out once installed, which is precisely why it commands the loyalty, and the margins, that it does.

The bear case is newer and louder. If the value in software shifts from the interface to the AI layer sitting on top of it, incumbents built for a headcount-priced world could find their pricing power draining away faster than their revenues suggest.

Every established vendor now insists it is on the right side of that shift. The industry line is that AI makes the software more valuable, not less, which is why every SaaS company is bolting AI features onto its product at once, hoping to reframe the threat as an upsell.

Taking Workday private would test that theory away from the quarterly glare. Freed from public earnings calls, Silver Lake could rework pricing, lean into AI and swallow a messy transition without watching the share price flinch at every wobble.

For now, though, it remains a reported deal and a telling one. Whether or not this particular buyout lands, private equity circling a name like Workday is a sign that someone with deep pockets thinks the market has mistaken an AI-shaped question for an answer.
