IBM Completes Its $34 Billion Acquisition of Red Hat
Announced October 28, 2018 and closed July 9, 2019, IBM's purchase of Red Hat was the largest software acquisition in history at the time — and a direct bet on hybrid cloud built around Linux and open source.
IBM and Red Hat entered into a merger agreement on October 28, 2018, and the acquisition officially closed on July 9, 2019 — Red Hat becoming a wholly owned IBM subsidiary in a deal valued at approximately $34 billion, the largest technology software acquisition in history at the time.
The terms
Each share of Red Hat common stock converted into the right to receive $190 per share in cash — the transaction was funded through a combination of debt and cash, financed in part through debt IBM had issued earlier that year specifically for this purpose.
Why IBM wanted Red Hat specifically
The stated rationale centered on hybrid cloud: combining Red Hat’s open-source portfolio and developer community — Red Hat Enterprise Linux, OpenShift, and the broader Linux and Kubernetes ecosystem it had built expertise in — with IBM’s own enterprise infrastructure and industry relationships, to compete more credibly against AWS, Microsoft Azure, and Google Cloud in enterprise cloud adoption.
An unusual acquisition structure
IBM committed to keeping Red Hat as a distinct unit within IBM, preserving its open-source development practices and independence rather than folding it directly into existing IBM product lines — a deliberate structural choice meant to protect the community trust and engineering culture that made Red Hat valuable in the first place, rather than risk diluting it through direct integration.
Why this deal mattered beyond the price tag
A company built entirely around commercially supporting free and open-source Linux distributions being acquired for $34 billion was, itself, a significant data point about how central Linux and open source had become to enterprise IT by 2019 — a very different world from Linux’s hobbyist-project origins covered in the history of Linux elsewhere on this blog. The acquisition remains one of the clearest illustrations of open-source software’s transition from an alternative to mainstream enterprises’ primary infrastructure bet.
