Why Microsoft put money into Apple
In 1997, Apple was struggling financially, and Microsoft agreed to buy $150 million in Apple stock. The investment gave Apple cash and, just as importantly, signaled that a major technology company expected it to remain in business. Microsoft also agreed to continue making its Office software for the Mac, keeping an important program available to Apple customers.
The deal was part of a broader settlement between the companies. They agreed to cross-license patents—permission for each to use certain technologies covered by the other’s patents—and resolved disputes over software. Microsoft’s shares were non-voting, so the investment did not give it control of Apple.
Competition was useful to Microsoft
Microsoft dominated personal-computer software, especially through Windows and Office. That dominance had attracted antitrust scrutiny: regulators were examining whether the company was using its market power unfairly. A functioning Apple offered a visible alternative to Windows, making the computer market look less like a one-company world.
That did not mean Microsoft’s main goal was to rebuild Apple into a powerful rival. Keeping the Mac platform alive also protected Microsoft’s own business: Mac users were customers for Office, and a deal that reduced legal conflict could benefit both companies. The investment served several interests at once—commercial, legal, and competitive.
A lifeline, not the whole recovery
The cash and agreements helped Apple through a precarious period, but they did not by themselves produce its later turnaround. That depended on Apple’s own decisions and products in the years that followed. Microsoft’s role was narrower but consequential: it helped keep Apple operating at a moment when its future was uncertain.
The memorable twist is that Microsoft could benefit from Apple’s survival without wanting Apple to surpass it. A rival made the market more credible—and a living Mac platform kept Microsoft software in customers’ hands.
