On 18 January 2022, Microsoft announced it would buy Activision Blizzard — the publisher behind Call of Duty, World of Warcraft, Diablo, Overwatch and Candy Crush — for $68.7 billion in cash. It was, and remains, the biggest acquisition the video game industry has ever seen, and the largest deal in Microsoft's history by a wide margin. Its previous record, LinkedIn in 2016, cost a comparatively modest $26.2 billion.
The financial terms were the easy part. Microsoft offered $95.00 per share, an all-cash bid that valued the company at $68.7 billion inclusive of Activision's net cash. Activision's stock — which had been battered by a workplace-misconduct scandal — jumped roughly 25% on the news. For a deal of this size, the structure was almost boringly clean: no stock component, no financing contingency, no auction.
And then nothing happened for twenty-one months. What followed was not a negotiation over money. It was a war of attrition with competition regulators on three continents — one that ended in a federal courtroom in San Francisco, a restructured deal, and a concession that handed a rival a 15-year head start in cloud gaming. This is the breakdown.
01 Why Microsoft paid up
A $69 billion bet on how people will buy games
To understand the price, you have to understand what Microsoft thought it was buying. It was not really buying Call of Duty. It was buying a thesis about the distribution of games — and three assets that map directly onto that thesis.
The first is subscription content. Microsoft's gaming strategy is built around Game Pass, a Netflix-style service where players pay a monthly fee for a library rather than $70 per title. A subscription service lives or dies on its catalogue. Owning Activision means owning some of the most-played franchises on earth and being able to put them in the box — making the subscription dramatically harder for a rival to match.
The second is mobile. This is the quietly decisive piece. Through King, Activision owns Candy Crush — one of the highest-grossing mobile games in the world. Microsoft has consoles, a PC platform, and a cloud service, but it has had almost no presence on the phone, which is the single largest gaming platform by players. King is a ready-made entry point into a market Microsoft had repeatedly failed to crack on its own.
The third is simply scale and content gravity. On close, Microsoft would become the world's third-largest gaming company by revenue, behind only Tencent and Sony — the kind of catalogue depth that compounds across every screen it sells to.
Put together, the bet looks like this: games are shifting from one-off purchases toward subscriptions and cross-device streaming, and whoever owns the deepest catalogue controls that transition. From Microsoft's seat, $68.7 billion was the price of not being locked out of the next decade of game distribution.
The financial terms took a week. The regulatory fight took twenty-one months.
02 The regulatory wall
Three regulators, three different answers
A deal this size needs clearance in every major market it touches. Microsoft filed with competition authorities around the world — and the three that mattered most, the European Commission, the UK's Competition and Markets Authority, and the US Federal Trade Commission, looked at the same transaction and reached three different conclusions.
The core worry was the same everywhere, and it has a name: vertical foreclosure. Microsoft owns a console, a PC platform and a cloud service — distribution. Activision makes content. The fear was that Microsoft could take blockbuster franchises like Call of Duty and make them exclusive, or degrade them, on a rival's platform — using content it now owned to weaken Sony's PlayStation and to dominate the young cloud-gaming market before it matured.
Microsoft's answer was to sign binding contracts that made foreclosure look commercially irrational: a string of 10-year deals committing to keep Call of Duty on rival platforms, including Nintendo and several cloud providers. Whether that was enough depended entirely on which regulator you asked.
The split is the most instructive part of the whole saga. The European Commission took Microsoft's licensing promises and cleared the deal in May 2023. The FTC didn't trust promises about future behaviour — it sued, sought a court injunction to stop the deal closing, and in July 2023 a federal judge in California ruled against it, finding the agency hadn't shown the merger would substantially lessen competition. The FTC kept appealing long after the deal closed, and eventually dropped the case in 2025.
And then there was the CMA. The UK regulator did something the others didn't: it rejected behavioural promises outright, and in April 2023 it blocked the deal — specifically over cloud gaming. That was the single biggest threat to the transaction, and it could not be litigated away. It had to be engineered away.
03 The concession that closed it
How selling a right to Ubisoft saved a $69 billion deal
With the CMA's block standing in the way, Microsoft did something unusual: rather than appeal indefinitely, it changed the deal itself. The restructure was narrow but structural. Before Microsoft could complete the acquisition, Activision's cloud-streaming rights were carved out and sold to a third party — French publisher Ubisoft.
This is the key move, so it's worth being precise about it. Microsoft still acquired Activision Blizzard and all its franchises. But it did not acquire the right to exclusively stream Activision's games over the cloud. Ubisoft got those rights — for 15 years, across PC and console, for markets outside the European Economic Area — and crucially, Ubisoft can license that content to any cloud provider, including Microsoft's competitors.
This is why the CMA's role was the deciding vote. The EU and the US were arguing about whether Microsoft's promises were trustworthy. The CMA changed the question entirely: instead of trusting a promise, it demanded a structure where the harmful outcome simply wasn't possible. On 13 October 2023, with the restructured deal in hand, the CMA cleared it — and Microsoft closed the same day.
The number that disciplined everyone
The merger agreement carried a $3 billion reverse termination fee — money Microsoft owed Activision if the deal failed to close. A break fee that large changes behaviour: it's why Microsoft kept extending deadlines and re-engineering the deal rather than walking away. When the cost of failure is $3 billion, you find a way to make the structure work.
04 Why it matters
The lesson isn't about gaming
It's tempting to read this as a gaming story. It isn't. The Microsoft–Activision saga is a near-perfect case study in a truth that doesn't fit on a deal announcement: for large acquisitions, signing the contract is the beginning, not the end.
The price was agreed in days. Shareholders were never the obstacle. What consumed twenty-one months — and forced a publisher to hand a rival a 15-year asset — was the gap between agreeing to a deal and being allowed to complete one. In an era of assertive antitrust enforcement, that gap is where deals now live or die.
- 01 Strategic logic explains the price. $68.7 billion only makes sense if you see it as a bet on subscriptions and cross-device distribution — with mobile, via King, as the asset Microsoft couldn't build itself.
- 02 Regulatory risk is deal risk. The same transaction got three different verdicts. When you assess a large merger, the question isn't just "is this a good deal" — it's "will three governments let it happen."
- 03 Behavioural vs. structural remedies. The EU accepted promises; the UK demanded a changed structure. Structural remedies are harder to give but far more durable — and regulators increasingly prefer them.
- 04 The break fee sets the incentive. A $3 billion reverse termination fee is why Microsoft restructured instead of walking. Always read the break fee — it tells you how hard each side will fight to close.
- 05 One regulator can rewrite a global deal. The CMA didn't just rule on the UK — its objection reshaped the transaction's worldwide structure. Jurisdiction size doesn't equal leverage.
