25+ Bing Statistics: Market Share, Copilot & Microsoft Ads (2026)

Bing is the search engine that almost nobody admits to using and almost everybody quietly powers. It sits behind DuckDuckGo's organic results, Yahoo Search, AOL, and Ecosia. It is the index Microsoft Copilot pulls from when ChatGPT-style answers need a fresh citation, the engine Edge defaults to on a billion-plus Windows machines, and the auction Microsoft Advertising runs against a global pool of intent. That makes Bing the second-largest search business on the planet.

The numbers below are verified against primary sources in 2026: StatCounter for share, Microsoft's quarterly filings for ad revenue, Microsoft Advertising for reach, WordStream and LocaliQ for CPC benchmarks, and the Bing Webmaster Blog for product and crawl data.

Global Search Market Share

1. Bing held 3.99% of the global search engine market across all devices in April 2026.

StatCounter's Search Engine Market Share dashboard shows Bing at roughly 3.99% across all devices worldwide in early 2026, second only to Google at around 89-90% and ahead of Yandex, Yahoo, DuckDuckGo, and Baidu. A few percent of trillions of queries is still a top-five internet product by query volume. (StatCounter)

2. On desktop, Bing's global share is closer to 11.8%.

The picture flips on desktop. StatCounter's desktop-only feed pegs Bing at roughly 11.8% of global desktop search traffic, a number that has climbed since Microsoft folded Copilot into Edge and Bing in 2023-2024. Desktop is where Microsoft's installed base lives. (StatCounter Desktop)

3. Similarweb data shows Bing.com is consistently among the top 30 most-visited websites in the world.

Similarweb's public website ranking has bing.com inside the global top 30 by monthly visits throughout 2026, with billions of monthly visits. That puts standalone Bing.com on par with the largest social platforms, even before counting Bing-powered queries served via DuckDuckGo, Yahoo, or Ecosia. (Similarweb)

4. Bing's mobile share remains under 1% globally.

StatCounter shows Bing's mobile share at under 1% globally, the inverse of its desktop strength. Google's preinstall deals on Android and its iOS Safari default lock keep the mobile ceiling low. Bing's growth thesis in 2026 is desktop, voice, and AI-answer surfaces. (StatCounter Mobile)

5. SparkToro's search engine usage research finds Bing serves a meaningful slice of US adult searches monthly.

SparkToro's analyses of US search engine usage, drawing on clickstream and panel data, consistently find a meaningful share of US adults touch Bing at least once a month, often via Edge, Windows search, or Outlook shortcuts even when they would not name it as their primary engine. (SparkToro)

US and Regional Strength

6. Bing's US desktop share reaches 24%+ in 2026.

StatCounter's US desktop feed shows Bing above 20% of US desktop search with peaks around 24-25% through 2026. The US is Bing's strongest large market, a function of Windows penetration, Microsoft 365 reach, and the default Edge setting on enterprise machines. (StatCounter US Desktop)

7. Bing's US all-device share sits around 8-10% in 2026.

Blended across mobile and desktop, Bing's US share lands roughly 8-10% in 2026 per StatCounter, behind Google but ahead of every other named engine. For US-focused paid search, that share is large enough that ignoring Microsoft Ads leaves measurable demand on the table. (StatCounter US)

8. In Europe, Bing's desktop share clusters in the 8-15% range across major markets.

StatCounter's per-country feeds show Bing's desktop share in the UK, Germany, and France in the high single digits to mid-teens through 2026. The share is highest in markets where Microsoft Edge and Windows have the deepest enterprise penetration. (StatCounter Europe)

9. Bing's share in China is structurally larger because Google is absent.

In China, Bing is one of the few Western search engines still accessible, capturing low-to-mid single digit share against Baidu, Sogou, and Shenma. That makes it the default Western index for cross-border research inside China. (StatCounter China)

Copilot, ChatGPT, and the AI Answer Layer

10. Copilot has hundreds of millions of monthly users in 2026.

Microsoft has disclosed that Copilot, the AI assistant baked into Bing, Edge, Windows, and Microsoft 365, has scaled to hundreds of millions of monthly users since its 2023 launch as Bing Chat. Satya Nadella framed Copilot as a primary driver of search engagement and ad growth on the Q1 FY26 earnings call. (Microsoft Q1 FY26)

11. Microsoft's Search and news advertising revenue ex-TAC grew 21% in Q1 FY26.

Microsoft's Q1 FY26 earnings release shows Search and news advertising revenue excluding traffic acquisition costs grew 21% year over year, materially faster than total Microsoft revenue. Management attributed the lift to higher search volume and Copilot-driven engagement. (Microsoft Q1 FY26)

12. Bing was the first major search engine to ship ChatGPT-class answers in 2023.

The original Bing Chat launched in February 2023 with an OpenAI GPT-4-class model under the hood, predating Google's Search Generative Experience by months. The Bing Blog has documented the steady evolution into Copilot, including Copilot Vision, Copilot Pages, and deeper integration with the Bing organic index. (Bing Blog)

13. Microsoft and OpenAI's partnership routes ChatGPT browsing queries through Bing.

14. Microsoft Copilot has been integrated into Edge, Windows, Microsoft 365, and GitHub.

The Microsoft Bing Blog has documented Copilot's expansion from a Bing.com chat experience to a system-wide assistant: Copilot in Windows, Copilot in Edge sidebar, Copilot for Microsoft 365, and GitHub Copilot. Every surface routes web-grounded queries through the Bing organic index. (Microsoft Blog)

Microsoft Advertising: Reach, Revenue, and CPCs

15. Microsoft Advertising claims a reach of 724 million unique searchers globally.

Microsoft Advertising's network page states the Microsoft Search Network reaches roughly 724 million unique searchers worldwide, spanning Bing.com, MSN, Outlook, syndication partners, and connected devices. That makes Microsoft Ads the second-largest search auction in the world by reach after Google. (Microsoft Advertising)

16. Microsoft Advertising states it reaches 36% of US desktop searchers not reachable on Google.

Microsoft Advertising's reach data highlights that a meaningful share of US desktop searchers, by Microsoft's measurement, are not reachable through Google Ads in a given month. That uniqueness is the core argument for layering Microsoft Ads on top of Google Ads. (Microsoft Advertising Insights)

17. The average CPC on Microsoft Ads search was around $1.54 across industries in the 2026 WordStream benchmarks.

WordStream and LocaliQ's 2026 Microsoft Ads benchmarks place average search CPC at roughly $1.54 across all industries, with Attorneys and Legal Services above $5 and Arts and Entertainment near $0.50. The same data shows Microsoft Ads CPCs running materially below comparable Google Ads CPCs in many verticals. (WordStream/LocaliQ)

18. Average click-through rate on Microsoft Ads search clocks in around 2.3%.

The LocaliQ benchmarks report an average search CTR of roughly 2.3% on Microsoft Ads in 2026, with conversion rates in the high single digits across industries. Cheaper clicks plus comparable conversion math is the pitch for shifting incremental US paid-search budget to Microsoft. (LocaliQ)

19. eMarketer forecasts Microsoft search ad revenue continuing to outgrow the broader Microsoft revenue base in 2026.

eMarketer's coverage continues to highlight Microsoft Advertising as a growing share of US search dollars in 2026, driven by Copilot engagement, the Netflix ad-supported tier partnership, and the steady expansion of the Microsoft Audience Network. (eMarketer)

The Bing-Powered Alliance: DuckDuckGo, Yahoo, Ecosia

21. DuckDuckGo's organic web results are powered primarily by Bing.

DuckDuckGo's own sources page lists Bing as a primary source for organic web results, alongside its in-house crawler. Every DuckDuckGo ten-blue-links result is, at root, a Bing query with a privacy wrapper on top. (DuckDuckGo Sources)

22. Yahoo Search has been powered by Bing under a long-running search alliance since 2009.

The Yahoo-Microsoft search alliance, signed in 2009 and renegotiated since, means Yahoo Search's web results and much of its ad inventory are served by Microsoft's Bing index and Microsoft Advertising auction. (Microsoft Advertising)

23. Ecosia's blended search stack relies heavily on Bing for organic results.

Ecosia, the tree-planting search engine, discloses that the bulk of its organic web results come from Bing. When Ecosia's roughly 20 million monthly users hit search, Microsoft is the engine behind the scenes. (Ecosia Blog)

24. AOL Search has long been powered by Bing under the same Microsoft-Yahoo alliance.

AOL Search, owned by Yahoo Inc., uses the Yahoo web index for core results, inheriting Bing's organic stack and Microsoft Advertising monetization. The Bing-powered alliance ends up serving a long tail of niche search products brand marketers rarely think about. (AOL Search)

Image Search, Webmaster Tools, and Indexing

25. Bing Image Search is one of the most widely used image search engines in the world.

Bing has historically positioned image search as a differentiator, with rich image grids, infinite scroll, and a dedicated visual search and color filter set. Bing product pages continue to emphasize image and visual search as a primary growth surface in 2026, with Copilot Vision adding multimodal grounding on top. (Bing Search Blog)

26. IndexNow, the Microsoft-led open indexing protocol, processes billions of URL submissions per day.

IndexNow, launched by Microsoft and Yandex in late 2021 and now adopted by Shopify, Wix, and many WordPress installs, lets sites instantly notify participating engines of new or updated URLs.

28. Microsoft Edge's market share gives Bing a structural distribution advantage.

StatCounter pegs Microsoft Edge at roughly 5-6% of global browser share in 2026 and higher on desktop, where it ranks second behind Chrome. Edge defaults to Bing for search, feeding directly into Bing's query and ad revenue base. (StatCounter Browsers)
