Microsoft Bing Ads Revenue Q4 FY2026 in Actual Dollars

Microsoft Bing ads revenue was $3,859 million in the quarter ended 30 June 2026. For the full fiscal year it was $15,176 million. Those are the real figures, and until this month Microsoft had never published them.

For years the only number Microsoft gave for its search advertising business each quarter was a growth percentage. Ten percent up, twelve percent up, and so on. Search Engine Roundtable has tracked that percentage every quarter, and every article about Bing's ad business has been built on it, including our own earlier piece on Bing ads revenue. Nobody outside Microsoft could say what the business was actually worth in dollars, quarter by quarter.

That changed on 2 September, when Microsoft restructured its financial reporting and, to help investors adjust, published a deck restating two full years of revenue by product line. That deck contains a row called search advertising, in dollars, for all eight quarters of fiscal 2025 and 2026. It also contains the same row restated under the new definition, which adds LinkedIn's advertising business. This article is built on that deck, and it is the first time these figures have been laid out for advertisers.

Microsoft Bing ads revenue in dollars, for the first time

Here is the search advertising line as Microsoft reported it under the old structure, which covers Bing search, MSN and the Microsoft Audience Network. All figures are in millions of US dollars.

So Microsoft Bing ads revenue grew from $13.9 billion to $15.2 billion in a year. That is $1.3 billion of new advertiser spend, and it puts Bing's ad business at roughly twice the size of Taboola and Teads combined.

Two things stand out. The growth is real but modest, at 7 to 9 percent on gross revenue in the last three quarters. And the quarters are flat across the year. Bing's ad business does not have a strong seasonal shape. Q2, which covers the holiday period, is barely bigger than the quarters around it.

The percentage Microsoft reports each quarter, and the one Search Engine Roundtable tracks, is a different calculation. It strips out traffic acquisition costs, the money Microsoft pays partners like Yahoo and DuckDuckGo to carry Bing ads. On that ex-TAC basis the four quarters of fiscal 2026 grew 16, 10, 12 and 10 percent. The gross figures above grew more slowly than that, which means Microsoft has been paying out a smaller share to partners. The business is keeping more of each dollar.

The restated version, and what LinkedIn adds

From fiscal 2027, which began on 1 July, Microsoft reports a line called search and advertising instead. It adds LinkedIn Marketing Solutions, which is LinkedIn's ad business, and LinkedIn Premium subscriptions to the old search advertising line. The deck restates the last eight quarters under that definition so investors can compare.

Subtract one table from the other and you get LinkedIn's contribution: $9,659 million for fiscal 2026, or 39 percent of the new combined line. Bing is the other 61 percent.

On the ex-TAC growth measure, the effect is clearer still. Microsoft's deck shows both versions side by side for every quarter of fiscal 2026.

The same fourth quarter is 10 percent growth under the old definition and 13 percent under the new one. LinkedIn advertising has been growing faster than Bing, so folding it in lifts the blended rate by three points. When Microsoft reports its first quarter of fiscal 2027 in late October, the number it publishes will be the restated kind. Anyone comparing it to the 10 percent from July will be comparing two different businesses.

The guidance that nobody reported

The deck also restates Microsoft's outlook for the current quarter, and this is the part that matters most for anyone buying Microsoft Bing ads.

On 29 July, under the old structure, Microsoft guided search advertising revenue ex-TAC to grow in mid-single digits for the quarter ending 30 September. That was a step down from the 10 percent just reported, and it went largely unremarked because the earnings call was about Azure.

In the September deck, the adjusted outlook for the new search and advertising line is growth in mid to high single digits. The difference between the two outlooks is LinkedIn. Which means Bing on its own is being guided from 10 percent last quarter to somewhere around 5 percent this quarter, and the LinkedIn fold-in is what lifts the reported figure back toward the high single digits.

Put plainly, Microsoft expects its Bing ad business to grow at about half the rate it just did, and the reporting change will make that harder to see.

What is going on around it

Bing's ad business now sits in a segment called Devices and Consumer alongside Xbox and Windows OEM, and the rest of that segment is not doing well. Xbox revenue fell from $23.5 billion in fiscal 2025 to $21.8 billion in fiscal 2026. Windows OEM and devices was flat at about $17.1 billion. Search and advertising was the only line in the segment that grew, and it grew by $2.7 billion on the restated basis.

The current quarter outlook for the segment is worse. Microsoft guided Windows OEM and devices revenue to decline in the low twenties percent, and Xbox content and services to decline in mid-single digits with hardware falling too. Search and advertising, at mid to high single-digit growth, is once again the only line pointing up.

Meanwhile the company as a whole is guiding Azure to grow 44 to 45 percent and expects capital spending above $50 billion this quarter, almost all of it on AI infrastructure. Advertising is a $25 billion business inside a company that will spend twice that on data centres in three months. So advertising is important to Microsoft, and it is not what Microsoft is organised around. The reporting change reflects that.

What this means for advertisers

Three things, and none of them is a reason to pull spend.

Bing is a $15 billion ad platform growing at 7 to 10 percent, and it is the healthiest thing in its segment. The dollar figures confirm what the percentages implied. This is a large, stable, profitable ad business that Microsoft has every reason to keep investing in, because it is holding up a consumer division where everything else is falling.

Growth is slowing, and from October the reported number will hide that. Mid-single-digit growth on Bing alone is the true current run rate. The published figure will be higher because LinkedIn is in it. If you use Microsoft's reported ad growth as a signal for how the Bing auction is behaving, stop. From now on it is a different metric.

The product is moving faster than the accounting suggests. In the same five weeks that produced this restatement, Microsoft put sponsored results inside Copilot answers for the first time and expanded them to shopping ads within days, which we covered in Bing Copilot ads. A business guided to mid-single-digit growth is, at the same time, placing paid results inside its flagship AI product ahead of where Google was at the same stage. Slowing revenue growth and aggressive product investment are both true at once, and for an advertiser the second matters more.

If you are deciding whether Bing belongs in your mix, the deck settles the question of whether the platform is real. It is. Whether it works for your category comes down to the things it always has: an older, desktop-heavy audience, the Audience Network placements you did not choose, and how Microsoft matches your keywords. We cover all of that in our guide to the Bing Ads agency account.

The short version

Microsoft Bing ads revenue was $3.86 billion in Q4 FY2026 and $15.2 billion for the year, up 9.4 percent. Microsoft published those dollar figures for the first time in September, alongside a restated version that adds LinkedIn's $9.7 billion advertising business to the same line. The restated fourth quarter shows 13 percent growth instead of 10. Guidance for the current quarter is mid-single digits for Bing alone and mid to high single digits with LinkedIn.

The platform is large, growing and safe. The growth is slowing, and the new reporting will make the slowdown harder to read. Judge Bing by your own account from here, because the earnings line just stopped measuring it. AdScaleLab Does Proper Research Before Publishing.
