Ranked: Where the iPhone Costs the Most in 2026

Who Has the Most Followers on X?

There are many ways to grow a social media following. When looking to outperform world leaders, however, it helps to own the platform itself.

This visualization ranks the 15 most-followed people on X (formerly Twitter) as of September 2026. Accounts belonging to brands or companies, including X itself, have been excluded.

The ranking includes political leaders, musicians, athletes, and business figures from around the world.

How Musk Became X’s Most-Followed Person

In April 2022, Elon Musk launched an unsolicited offer to acquire Twitter. By the end of October, he had acquired the social media platform for a reported $44 billion.

Within five months of completing the deal, Musk surpassed former U.S. President Barack Obama as the most-followed person on the platform.

The table below ranks the world’s 15 most-followed people on X as of September 2026.

Musk changed the company’s name from Twitter to X in 2023, around the same time he surpassed Obama in followers. The new branding also aligned the platform more closely with other Musk ventures such as SpaceX.

Musk reduced content moderation on the platform and reinstated some formerly banned accounts while also directing the amplification of his own tweets in the algorithm. X’s workforce shrank by roughly 80% in the first few months after his purchase through mass layoffs and voluntary resignations.

Presidents and the Political Class

One of the accounts Musk reinstated shortly after his purchase was that of Donald Trump, the 45th and 47th President of the United States.

Trump had been suspended from Twitter in January 2021 following the actions of his supporters in the final days of his first presidency. The sitting U.S. president has 112 million followers on X, though he is far more active on his own competing social media platform, Truth Social.

Trump’s predecessor, Barack Obama (119 million), has the second-most followers on X. Meanwhile, Indian Prime Minister Narendra Modi (107 million) ranks fifth.

Portuguese soccer star Cristiano Ronaldo (114 million) is the only person among the top five who is not associated with politics. Ronaldo is also the world’s most-followed person on X rival Instagram.

The Decade of Perry

Outside the top five, no figure reaches 100 million followers. Rihanna comes closest with 99 million. Nearly a sixth of X’s roughly 650 million active users follow the Barbadian singer.

Rihanna is followed by a string of fellow musicians, including Justin Bieber (92 million), Katy Perry (90 million), Taylor Swift (84 million), and Lady Gaga (75 million).

Katy Perry holds another notable distinction. The American singer was the world’s most-followed X account for the longest period on record, holding the title for 2,110 days from late 2013 until Obama surpassed her in 2019.

Ranked: The Countries Using AI Tools the Most

AI tools drew 125.7 billion website visits in 2025, up 46% from the year before.

This graphic ranks the countries that generated the most visits to AI tool websites in 2025, using data from AITools.xyz, which compiles SEMrush and Ahrefs traffic estimates across more than 9,500 AI tool sites.

The metric counts website visits, not users. One person can make many visits, and visits to different tools are counted separately. Mobile-app sessions are also excluded, which can understate usage in app-first markets such as China.

The U.S. Makes Up One in Five AI Visits Worldwide

The gap between first and second place is substantial: U.S. traffic was more than double India’s, while the top three countries together generated 36.5% of AI tool website visits worldwide.

The table below shows the 30 countries with the most visits to AI tool websites in 2025, along with each country’s share of global visits:

Brazil ranks third with 7.0 billion visits, well ahead of Germany (4.6B), the UK (3.8B), and France (3.4B).

Population helps explain the strong showing from India and Brazil, but several Southeast Asian markets also rank remarkably high. Indonesia places sixth with 3.7 billion visits, while the Philippines ranks 10th with 2.9 billion.

Both finish ahead of larger or wealthier economies such as Italy (2.6B), Spain (2.5B), and South Korea (2.3B).

Why China Ranks So Low in AI Tool Site Visits

China is the world’s second-largest AI power by model development, yet it ranks 15th here with 2.4 billion website visits.

China’s low position partly reflects what this dataset measures. Major Western AI tools such as ChatGPT, Gemini, and Claude have limited availability in China, while domestic assistants such as DeepSeek, Doubao, and Quark attract significant usage through mobile apps. Because this ranking measures website traffic and excludes app sessions, it should not be interpreted as a measure of China’s total AI usage.

The U.S. lead also looks different depending on the metric. The country generates the most AI tool website traffic by a wide margin, yet Microsoft ranks it only 21st for AI adoption, with 31.3% of working-age adults using AI regularly compared with 70.1% in the UAE.

As this map of AI adoption by country shows, the highest penetration rates are typically found in much smaller economies.
