How to Set Up X (Twitter), Plus Demographics and Stats (2026)

X (formerly Twitter) is the most measured, debated, and politically charged social platform on the internet. It is also the one whose actual numbers are hardest to verify, because it has been a private company since Elon Musk's October 2022 acquisition and no longer publishes audited user or revenue data. Elon Musk says X has 600 million monthly active users, of which about half use it daily.¹ Independent app analytics firms estimate the real number is closer to 561 million MAU with daily mobile users down 15% year-over-year and Threads passing X in mobile DAU in September 2025.² The truth is somewhere between, and this guide is honest about that uncertainty.

This guide covers what X actually is in 2026: who's still using it, how the political center of gravity flipped, what the new Grok/Phoenix algorithm rewards, how Premium and creator monetization actually work, and how X compares to Threads, Bluesky, and Mastodon. Where data is private or contested, we say so.

How to set up an X account

Creating an X account is free. X's help page walks through phone, Google, Apple, and email sign-up, then profile setup. The steps below follow that page, and the sign-up screen is the one X shows on the web today.³

The short version:

1. Go to x.com/signup
2. Continue with a phone number, Google, Apple, or an email address
3. Confirm the email or the text code
4. Add a profile photo, a header, and a bio
5. Pick a username of 15 characters or fewer

Before you start

You need an email address or a phone number you control. An email address can only be tied to one X account at a time, and it is not shown on your profile. A phone number is confirmed with a code by text, and you can ask for a voice call instead.³

X also lets you sign up with Google or Apple from the same screen. If you share your email on the Apple path, X uses it for account messages such as a password reset.³

Step 1: Open the sign-up screen

Go to x.com/signup. The screen is titled See what's happening and offers Continue with phone, Continue with Google, Continue with Apple, or an email address. Pick one and follow the prompts. X then shows Customize your experience, including whether X may track where you see X content across the web, before you land in the app.³

Step 2: Set up your profile

Once the account exists, X's next step is the profile. Sign in, open your profile, and choose Edit profile. You can change:⁴

• Header photo, which X also calls a banner. Recommended size is 1500 by 500 pixels
• Profile photo. Recommended size is 400 by 400 pixels
• Name
• Bio, up to 160 characters
• Location and website
• Birth date, with a control for who can see it

Photos can be JPG, GIF, or PNG. X does not support animated GIFs for the profile photo or the header. Choose the camera icon, then Upload photo or Remove, and save. On a brand-new account, the display name stays locked until a profile photo and a header are uploaded.⁴

Your username, the handle after the @, is what people use for replies, mentions, and the profile URL. It must be 15 characters or fewer, and X refuses handles that use its reserved words, such as Twitter or Admin. X suggests a few free handles during sign-up, and you can change it later in settings if the new one is free.³

You can also pin one post to the top of the profile: open the post menu and choose Pin to your profile.⁴

Step 3: Learn the post limits before you write

A normal post is text plus media. X's help page says you can include up to 4 photos, a GIF, or a video, and that a standard post holds 280 characters.⁵

X's published media guidance lists JPG, PNG, GIF, and WEBP images up to 5 MB, animated GIFs up to 15 MB, and standard video up to 512 MB with a duration from 0.5 seconds to 140 seconds. Subscribed accounts can upload 1080p video. Frame rate must be 60 FPS or less.⁶ posterly accepts JPEG, PNG, and WebP stills, a GIF, or one video, and it applies its own 512 MB ceiling on the video file. Images and video cannot share one post. The duration X accepts is decided when the upload starts, because it depends on the account.

Step 4: Turn on Premium only if you need longer posts

Longer posts are an X Premium feature. You write them in the same compose box. On the apps, the counter keeps going until 4,000 characters. On the web, X's help page says the box keeps going until 25,000 characters.⁵ Premium is optional. A standard account can post, reply, and follow without it.

Manage your X account with posterly

X handles account creation. posterly does not sign you up. Once the account exists, connect it from the Accounts page and schedule from the composer. The X scheduler is the product page for the same flow.

What you can schedule. Text, up to 4 images or one video, polls, and a thread of several posts sent in order. You can choose who is allowed to reply, mark a post as a paid partnership, and add an AI-generated label. Mentions work by typing the @username.

Character cap follows the connected account. A standard account is held to 280 characters. A verified, Premium, or blue account is held to 4,000. An organisation account is held to 25,000. That is the cap posterly enforces, including on each post inside a thread.

Links are blocked for now. posterly refuses an X post that contains a URL and asks you to take the link out before it will schedule. The same block applies to each post in a thread.

X Articles. A Premium account can publish a long-form Article from the composer: a title, a cover, and a Markdown body. The 280, 4,000, and 25,000 character caps do not apply to the Article body. In posterly you choose Article on the X tab of the composer, add a title of up to 200 characters, write the body in Markdown or the full-screen editor, attach up to four images (the first becomes the cover by default), and schedule it like any other post.

From an AI assistant. The X MCP server publishes the same posts, polls, and threads from Claude, ChatGPT, or Cursor. It can also read X analytics and report how many posts the workspace can still schedule.

X (Twitter) key numbers

The four figures below are the ones this guide relies on most. X is a private company and publishes no audited user data, so the first two are outside estimates.

Each figure carries its own source and date. Platforms revise their data, so follow the link for the latest number. More statistics are in the sections below.

What is X?

X is a real-time public conversation platform owned by xAI Holdings (Elon Musk's holding company combining X Corp and xAI). Originally launched as Twitter in 2006 by Jack Dorsey, Biz Stone, Evan Williams, and Noah Glass, it grew into the global default for breaking news, public discourse, and short-form text conversation. Musk acquired Twitter in October 2022 for $44 billion, rebranded it to X in July 2023, and merged X Corp into xAI in 2025.

Functionally, X in 2026 is several products bundled together:

• For You feed: algorithmic public timeline, now powered by a Grok-based transformer
• Following feed: chronological feed from accounts you follow
• Spaces: live audio rooms (the original Clubhouse competitor)
• Articles: long-form publishing (up to 100,000 characters)
• Vertical video: TikTok-style short video, with about 20% of session time
• DMs: direct messaging, now with encrypted chats for Premium users
• Grok: xAI's frontier AI model, integrated into the timeline and X DMs

X is also the only major social platform with a frontier-grade AI model directly plumbed into the user experience. Grok 4.1 (released November 2025) has a 2 million token context window, can read all of X's roughly 500 million daily public posts in real time, and powers the For You ranking model, the Grok chatbot, and Grok Imagine (image and video generation).⁷

Key X (Twitter) statistics in 2026

The honest set of numbers, with sources separated by what's self-reported by X versus independently measured.

The single most important caveat: X is private and self-reported numbers cannot be independently audited. Where Musk's claims and independent estimates diverge, we err toward the independent estimates while noting both. The audience range is approximately 540 to 650 million MAU.

What's happened to the user base since 2022

This is the most frequently misrepresented part of X's story, in both directions. The data:

Decline is real and documented:

• US daily mobile users down 23% from November 2022 (when Musk closed the deal) through early 2024
• Global app downloads down 38% YoY Oct 2022 to Sept 2023; US downloads down 57% in the same period⁸
• Total hours engaged on the platform fell about 6% YoY each quarter through 2023
• Churn up 30%+ vs October 2022 baseline
• Ad revenue collapsed from $4.4B in 2022 to $1.94B in 2024, a 56% drop

The 2025 stabilization:

• 2025 ad revenue grew to an estimated $2.26B (+16.5% YoY), the first growth year since the acquisition
• Q3 2025 quarterly revenue grew 17% YoY to $752M
• Subscription run rate hit $1 billion annually
• Total hours engaged stabilized in Q4 2024

The synthesis: X is meaningfully smaller and less commercial than it was in 2022, but the worst of the decline appears to be behind it. The platform is profitable, growing in subscription revenue, and stabilizing in ad revenue.

X demographics

The audience picture in 2026 is significantly different from what it was in 2022, in two important ways: smaller and politically inverted.

Global audience

By raw user count:

• United States: ~105 million users (the largest market, ~14 to 18% of total)
• Japan: ~71 to 75 million (highest per-capita penetration globally; Japanese users average 8h 10min per month on X, the world's highest)
• Indonesia: ~24 million
• Poland: ~23 million
• India: ~23 million
• United Kingdom: ~19 to 20 million
• Turkey, Germany, Mexico, Saudi Arabia round out the top 10

Asia holds about 43.5% of all X users, but the US drives roughly 50% of revenue despite being only 14 to 18% of the user base.⁹

By age, the audience skews young-adult:

• 18 to 24: ~32%
• 25 to 34: ~37.5% (largest single band)
• 35 to 49: ~21%
• 50+: ~9%

That's about 70% of users in the 18 to 34 bracket, slightly tighter than Instagram's 62% but with a meaningfully different audience profile.

Globally, X skews about 64% male, 36% female, the most male-skewed of the major social platforms.

United States audience (Pew Research)

US data on X is unusually contested because Pew's June 2025 fact sheet shows only 8% of US adults using X, a sharp drop from the 22% Pew measured in 2023. Pew's November 2025 update (which we treat as more methodologically aligned with their other recent platform measurements) shows the picture differently:

The single most documented demographic shift since Musk's acquisition is the partisan inversion. Pew's data:

• In 2023, 26% of Democrats vs 20% of Republicans used X
• In November 2025, 24% of Republicans vs 19% of Democrats used X¹⁰
• The share of Republicans saying X is "good for democracy" rose from 17% in 2021 to 58% in 2025; for Democrats it fell from 47% to 17%¹¹
• News influencers on X identify 28% right-leaning vs 21% left-leaning, the only major platform where right outnumbers left¹²

This is not a marketing claim; it's a peer-reviewed and Pew-documented finding. A 2026 Nature paper found that even short-term exposure to X's algorithmic feed shifted users' political opinions toward more conservative positions on policies, prosecutions, and Ukraine, and that the effect did not wear off quickly.¹³

What this means for content strategy

If your audience is US Republican-leaning, conservative tech, finance, crypto, defense, or sports, X reaches them more concentratedly than any other platform. If your audience is US progressive media, mainstream consumer, or center-left professional, much of that audience has moved to Threads, Bluesky, or LinkedIn. If your audience is Japanese, X is essentially mandatory because per-capita usage is the highest in the world.

What X is actually used for in 2026

X's use cases are narrower than they were in 2022, but the surviving ones run very deep.

1. Real-time news and breaking events

The defining use case. About 12% of all US adults regularly get news from X, and 57% of X users get news on the platform, the highest on/off ratio of any social network.¹⁴ During major news events (elections, sports finals, market crashes, breaking world events), X is still the default real-time discovery surface even for users who don't use it daily.

2. Sports, politics, and finance

These three verticals dominate X's most engaged communities:

• Sports Twitter is still arguably the largest sports-conversation surface on the internet, with English Premier League, NFL, NBA, MLB, F1, and tennis communities all heavily active
• Political Twitter post-2022 leans right and is highly active, especially on US elections and policy debates
• FinTwit (finance Twitter) and CryptoTwitter are the dominant real-time discussion communities for those topics; the audience there is small but dedicated and highly commercial

3. Tech and developer communities

Tech Twitter remains substantial, with software engineering, AI, startups, and dev tooling communities all active. Many tech founders, investors, and engineers use X as their primary public posting surface.

4. Customer service

X is unusually strong here: about 36% of brand customer-service replies arrive within 1 hour, the best response rate of any social platform.¹⁵ For brands, the platform is still the most effective public-facing customer-service channel.

5. Video

The 2025 to 2026 video push has been substantial. More than 4 out of 5 user sessions now include video, and X reported 8.3 billion videos viewed daily in 2024 (+40% YoY). Vertical video has reached 100 million users and 20% of session time.¹⁶

How the X algorithm works in 2026

The 2026 picture is meaningfully different from the 2023-era open-sourced algorithm. In October 2025, Musk announced Grok would replace the legacy ranker entirely, and the January 2026 release confirmed a new Grok-based transformer system, internally called "Phoenix", at the heart of For You ranking.¹⁷

The three-stage pipeline

1. Candidate sourcing: pulls roughly 1,500 candidate posts per user from the daily ~500 million post universe, using engagement-graph and topic similarity heuristics
2. Phoenix ranking: a Grok-based transformer model scores candidates on predicted engagement (likes, comments, replies, retweets, sends, dwell time)
3. Heuristics and diversity: applies hard rules (filtering blocked accounts, mixing topics to avoid filter bubbles, applying community-rules safety filters)

What the X algorithm actually rewards

The most useful takeaway from the public xai-org/x-algorithm repository is that X does not simply rank posts by likes. The For You system retrieves candidates, scores them against recent user behaviour, then filters and reweights the final feed. In the public ranking code, positive predicted actions include favourites, replies, reposts, profile clicks, link clicks, video quality views, shares, dwell, quotes, follow-author actions, and other engagement events.¹⁸

The negative side matters just as much. The same scoring path includes predicted not-interested, block, mute, report, and not-dwelled outcomes.¹⁸ In plain English: a post that earns a few likes but also creates quick skips, mutes, or "not interested" taps is not a win. X is trying to predict whether the right person will stop, interact, and want more from that author.

Top ranking signals

• Recency: far more important on X than on Instagram or LinkedIn; posts older than 24 hours rarely show in For You
• Engagement velocity: early replies, reposts, quotes, shares, and profile clicks teach the model faster than passive likes
• Recent user history: retrieval and scoring use recent action sequences, so people who engaged with your topic or account recently are easier to reach again¹⁸
• Dwell and not-dwell: posts need to hold attention long enough to avoid the quick-skip bucket
• Author and topic fit: candidate features include text, media, replies, quotes, language, author signals, topic IDs, and safety labels¹⁸
• Author diversity: repeated author dominance is attenuated, so posting more is not automatically better¹⁸
• Seen-content filtering: previously served posts can be filtered, which makes copy-pasting the same winner weaker than reframing it with a fresh angle¹⁸
• Negative feedback: mutes, blocks, reports, not-interested taps, and low dwell can remove or suppress candidates
• Media quality: video quality views and media interactions can help when the image or video adds proof, not decoration

What this means for creators

Two things. First, post when your audience is online. Recency matters more on X than anywhere else. Second, design for scored actions, not vanity likes. A good X post should make someone reply, dwell, click your profile, click through, share, follow, repost, quote, expand an image, or watch a video. If it does none of those, it is just a sentence in public.

The practical posting pattern is simple: use sharp first lines, short paragraphs, proof screenshots, specific trade-off questions, teardown prompts, and follow-up replies in the first 30 to 90 minutes. Avoid vague AI slop, repetitive product shilling, link-only posts, fake engagement bait, and recycled posts with no new angle. Those are how you train the feed to ignore you.

X Premium and creator monetization

This is the part of X that most resembles a SaaS business in 2026.

X Premium (and Premium+)

• About 2 million paid subscribers as of early 2025
• $1 billion annualized revenue run rate, confirmed by X Head of Product Nikita Bier
• Premium tiers: Premium ($8/month), Premium+ ($40/month, includes Grok 4.1 access)
• This surpasses Snapchat+'s $750M revenue but is far below Musk's original projection of 69 million Premium subscribers and 50% of revenue by end-2025

The honest framing: Premium is real and growing, but materially below the company's own ambitions. Subscription is now ~30% of total X revenue, not the 50%+ Musk targeted.

Creator payouts

X changed its creator payout program in 2026. According to TechCrunch (8 August 2026):¹⁹

• X stopped accepting new Creator Revenue Sharing participants and began winding the program down
• Existing participants kept earning through 7 September 2026
• Applications for the new Original Content Rewards program opened 8 September 2026
• Eligibility reported by TechCrunch: an active Premium subscription, at least 500 verified followers, and at least 500,000 Home Timeline impressions from verified users within 90 days
• According to TechCrunch, X says the aim is to reward original content (original reporting and analysis, photos or videos you made, memes or graphics you designed) over copied posts, re-uploads and reposts without meaningful change

TechCrunch did not report how much the new program pays, and we have not found an official payout rate, so this guide does not quote one. Figures for the retired program (revenue shares and per-impression rates) no longer apply. Check X's own creator pages for current terms before planning around the income.

Best for, not best for

Where X wins in 2026, and where it doesn't.

X is well-suited for

• Real-time news and breaking events: still the default discovery surface
• Sports, politics, finance, crypto, defense communities
• Tech and developer brands: many technical audiences still post primarily here
• Customer service: fastest response benchmarks of any platform
• Brands targeting US conservative or libertarian audiences: the largest concentration is here
• Audiences in Japan: highest per-capita penetration globally
• Public-facing thought leaders, founders, investors: short-form opinion still travels here

X is not the best fit for

• Mainstream US consumer brands: brand-safety concerns and the political shift make this riskier than 2022
• Center-left or progressive audiences: much of that audience has moved to Threads
• Long-form content: Articles exists but most reach is for short-form
• Visual brands: Instagram and Pinterest are stronger
• Predictable ad performance: X ad performance is more volatile than Meta or Google
• B2B lead generation: LinkedIn converts much better; see our LinkedIn guide

If your audience is split (e.g., a tech founder selling to both center-left and center-right professional audiences), the practical move in 2026 is to publish to X and LinkedIn or Threads in parallel.

How brands and creators use X in 2026

Three patterns that work consistently:

The "founder personal brand" approach. A founder, operator, or technologist publishes 1 to 5 short posts per day in their own voice, mostly opinions, observations, or behind-the-scenes from their work. Mix of text, images, screenshots, and occasional video. Used as the top-of-funnel for personal newsletter, product, or services. Tech and finance verticals work especially well here.

The "real-time community" approach. A brand or creator focused on a real-time vertical (sports, finance, crypto, news, gaming) uses X as the primary public surface for their audience. Live posts during events drive most engagement; the platform's recency-weighted algorithm rewards being present during news moments.

The "customer service plus brand" approach. A consumer brand uses X primarily for fast public-facing customer service, with light brand posting on the side. The 36% within-1-hour reply benchmark is industry-leading, and the public visibility of good service compounds reputation.

X vs Threads, Bluesky, and Mastodon

This is the question every brand and creator asks about X in 2026. The honest comparison:

Threads

• MAU: 400+ million (August 2025), up from 350 million in April 2025
• Mobile DAU: 115 million (June 2025), +128% YoY; passed X in mobile DAU in September 2025²⁰
• Time per day: 8 minutes, about a quarter of X's 31 minutes
• Profile: Meta-scale onboarding, friendlier brand-safety, less news/political content (though Meta is reversing some of that suppression)
• Best fit: lifestyle, consumer, mainstream audience

Bluesky

• Registered users: 40.2 million (November 2025), up from 13 million in October 2024
• DAU: down 40% YoY through October 2025, sitting around 1.5 million
• Profile: portable identity via the AT Protocol, custom feeds, high-trust conversation, journalist-and-technologist-heavy
• Best fit: tech-savvy users, journalists, niche professional communities

Mastodon

• MAU: single-digit millions
• Profile: federated, decentralized, ideologically pure
• Best fit: technical audiences, privacy-focused communities

Net assessment

X is still roughly 65% larger than Threads and 10x Bluesky by daily mobile users, and its time-per-day (31 minutes) is nearly 4x Threads (8 minutes). Threads is bigger by raw count but stickier on X. Bluesky and Mastodon are culturally significant but not commercially competitive in 2026. The winner-take-most dynamic in real-time public conversation is still X's, even at a smaller scale than 2022.

Final word

X in 2026 is harder to recommend simply than it was in 2022. The platform has shrunk meaningfully, faces real brand-safety concerns, and has politically inverted in ways that change the audience-fit calculation for many brands. At the same time, it remains the dominant platform for real-time news, sports, politics, finance, and tech conversation, and its 2025 ad revenue rebound suggests the worst of the advertiser exodus is over.

If your audience is sports, finance, crypto, tech, defense, or US conservative consumer, X is still where they are. If your audience is mainstream consumer or center-left professional, you should be on Threads or LinkedIn instead, and treat X as a secondary distribution channel.
