Telegram is not, in the strictest sense, a private messenger. Its default chats are not end-to-end encrypted; only its opt-in Secret Chats are. It is not, despite founder Pavel Durov’s branding, a non-commercial project; it now sells subscriptions, advertising and digital collectibles. And it is not, contrary to what its largest channels imply, a neutral platform; it has been the central distribution rail for protest movements, propaganda operations and economic war reporting in nearly every major conflict of the past decade. Telegram is something stranger and harder to categorise: a hybrid of WhatsApp, Discord, Substack and Reddit that has somehow accreted around a single mobile application and grown to roughly a billion monthly active users without ever quite belonging to any one country, regulator or business model.

From St Petersburg to Dubai

Pavel Durov launched Telegram in August 2013, eighteen months after he and his brother Nikolai had been forced out of VK, the Russian social-network they founded. The Durovs left Russia shortly afterwards, citing pressure from the Kremlin to hand over data on Ukrainian protesters, and the company eventually settled in Dubai. The product was built explicitly as a response to that pressure: it would not store messages on a single jurisdiction’s servers, it would publish open-source clients and a proprietary protocol (MTProto), and it would offer a layer of cryptographic privacy stronger than what WhatsApp then provided.

By 2018, Telegram had reached two hundred million monthly users. By 2020 the figure was four hundred million. The pandemic, the Hong Kong protests, the Belarusian uprising and the 2022 Russian invasion of Ukraine each delivered new tranches of users, often arriving as entire activist communities at once. Durov announced in March 2024 that the application had crossed nine hundred million monthly active users; later that year his team confirmed a billion.

The Architecture That Sets It Apart

Three architectural choices distinguish Telegram from WhatsApp, Signal and iMessage. First, it stores chat history on Telegram’s servers by default, which is what enables the application to work on multiple devices simultaneously without re-syncing. Second, it offers unlimited file size for documents and media — up to two gigabytes for the free tier and four for the Premium subscribers — which has made it the default file-transfer tool for journalists, designers and pirated media. Third, it exposes a full bot API that lets developers build automation, mini-games, customer-support agents and even entire e-commerce flows inside the chat interface.

The combination has been transformative for power users. A Telegram channel can broadcast to tens of millions of subscribers. A Telegram group can hold up to two hundred thousand members with granular admin controls. A Telegram bot can take payments, query a database and update users on a schedule. None of those operations are easy in WhatsApp, and none are possible at the same scale.

Channels: The Newsletter for the World That No Longer Reads Email

The single feature that defines Telegram in 2026 is the channel: a one-way broadcast stream that any user can subscribe to. Channels were introduced in September 2015 and have since become the dominant publishing format on the platform. Large news organisations, governments, central banks, military propaganda units, football clubs, religious movements and crypto-trading communities all distribute primarily through channels.

The Russian invasion of Ukraine in February 2022 turned channels into a global wartime medium. President Volodymyr Zelensky’s official channel passed two million subscribers within weeks. Russian milbloggers — independent reporters embedded with or close to Russian forces — accumulated millions of subscribers and emerged as a more agile information source than state media on either side. Several of those channels became significant enough to influence Russian military narratives and were occasionally cited by the Kremlin’s own press office. Channels run by Hamas, Hezbollah and the Israel Defense Forces during the 2023–24 Gaza war became another arena of competing claims, often the first place where photographs and video appeared before being amplified by Twitter / X.

The Bot Economy

Telegram’s bot API, first opened to developers in 2015, became the foundation of a small but unusual application ecosystem. Wallet bots that custody cryptocurrency; ride-hail dispatchers in countries with no app-store equivalent; informal banking interfaces; pirated streaming aggregators; and tens of thousands of niche utilities. By 2024 the platform’s “mini-apps” — bots that present a full HTML5 interface inside a chat — were running for tens of millions of users across categories from games to gambling.

The most-played mini-app of 2024 was a tap-to-earn game called Hamster Kombat. It briefly reached more than three hundred million monthly active users, mostly in Russia, the Commonwealth of Independent States and parts of Southeast Asia, before its launch of an associated cryptocurrency token caused an enormous engagement drop. The episode highlighted both the upside and the brittleness of the Telegram mini-app economy: the platform can deliver enormous distribution to a single product almost overnight, but the economic models that fund that distribution are often speculative.

Premium, Stars and TON

For most of its history, Telegram operated without meaningful revenue. The company financed itself through Durov’s personal capital and a controversial blockchain project, the TON (Telegram Open Network), which was wound down in 2020 under pressure from the U.S. Securities and Exchange Commission. The technology was later relaunched as a community-led project under the name TON (The Open Network), and Telegram retained a strategic interest in its ecosystem.

Beginning in 2021, the platform introduced sponsored messages inside channels above a one-thousand-subscriber threshold. In 2022 it launched Telegram Premium, a paid subscription tier that unlocks faster downloads, larger uploads, custom reactions and exclusive stickers. In 2024 it introduced Stars, an in-app currency for purchasing digital goods, and integrated the TON blockchain as a settlement layer for collectibles such as anonymous numbers and usernames. Durov disclosed in 2025 that Telegram’s annualised revenue had crossed one billion dollars and that the company was approaching profitability for the first time.

The Misinformation Problem

Telegram’s combination of large group sizes, public channels and minimal moderation has made it a focus of concern for researchers tracking misinformation, radicalisation and illegal content. Multiple academic studies have documented the use of Telegram by far-right movements in Europe, by QAnon networks in North America, and by state-backed influence operations in the Middle East and West Africa. Investigations by the BBC, Le Monde and Politico have flagged channels distributing child sexual abuse material and unregulated drug marketplaces, often persisting for months before takedown.

The platform’s response has historically been minimal — content moderation has been described internally as a “high-friction, low-priority” function — and that posture became a legal liability in August 2024 when Pavel Durov was detained at Le Bourget airport in France on a sealed warrant. He was charged with complicity in offences ranging from drug trafficking to the distribution of CSAM, on the theory that Telegram’s refusal to cooperate with French law enforcement constituted criminal negligence. Durov was released on bail and Telegram subsequently expanded moderation cooperation in France, the United Kingdom and parts of the European Union.

Encryption: Real, Limited and Often Misunderstood

One of the most persistent misconceptions about Telegram is that it is end-to-end encrypted by default. It is not. Standard one-to-one chats and group chats use server-client encryption: messages are encrypted in transit but Telegram’s servers can read them. Only Secret Chats — a one-to-one option not available in groups — use end-to-end encryption based on the MTProto protocol. Cryptographers have repeatedly critiqued MTProto over the years, though no successful break of the current version has been publicly demonstrated.

For privacy-aware users, Signal remains the more rigorous option. Telegram’s strengths lie elsewhere: in publishing reach, in cross-device synchronisation, in storage, in automation and in the cultural fact that for tens of millions of people in particular communities — Russian-speakers, crypto traders, journalists in authoritarian states — it is simply where the conversation happens.

Where Telegram Has Become Indispensable

The application’s geography reflects its political and technical biography. Russia and post-Soviet states remain its core market; in Russia, monthly reach is comparable to WhatsApp’s. Iran, where most Western platforms are blocked, has more than fifty million Telegram users. In Brazil, Telegram briefly approached WhatsApp in reach during the 2022 elections, when several political movements migrated to the platform after WhatsApp tightened forwarding rules. In Ukraine, the application is the primary medium for civil-defence alerts, military reporting and presidential communications. In Ethiopia, Pakistan and Indonesia, channels serve as the default news service for tens of millions of users.

Discord, Slack and the Adjacent Markets

Telegram does not have a direct competitor at its precise intersection of features. WhatsApp and Signal are stricter on privacy but lack channels, large groups and bots. Discord has communities and bots but is voice-and-text-first, with a different cultural identity centred on gaming and creator fandoms. Slack is an enterprise tool. Twitter / X is a public broadcast network without true private messaging at scale. The closest analogue in the Western consumer market is Reddit, but Reddit is a website by genealogy and remains less integrated into the smartphone-as-primary-device routine of emerging markets.

This is one reason why so much of Telegram’s growth has come from regions where smartphones are the primary computing device and where neither Reddit nor Discord ever achieved dominant local distribution. Telegram occupied a niche before any local competitor could and has held it through inertia, network effects and a steady cadence of feature releases.

The Durov Brand, For Better and Worse

Pavel Durov’s personal brand is unusual for a technology founder. He has refused to give traditional interviews to most major news outlets for years, communicates with users directly through his channel, posts shirtless photographs from gym sessions, and intervenes personally in disputes between users and moderators. He has portrayed Telegram as a free-speech project and has positioned himself as an adversary of intrusive state power, although his arrest in France complicated that posture.

His brother Nikolai, the chief technologist who designed the MTProto protocol, is the much quieter half of the partnership. The application’s technical reliability — uptime, file-handling, multi-device synchronisation — is largely attributed to his engineering culture. Together, the brothers have built an application that nominally has no headquarters, formally maintains a workforce of fewer than fifty employees, and yet runs one of the most influential publishing platforms on Earth.

What Telegram’s Next Chapter Looks Like

The next twelve to twenty-four months will define Telegram’s trajectory more than any period since the move from Saint Petersburg to Dubai. Three lines of pressure converge. Regulators in Europe, Brazil and India are demanding far more aggressive moderation. The TON-based digital-goods economy is either going to grow into a meaningful revenue base or fade as the second cryptocurrency-and-mini-app cycle exhausts itself. And the platform’s deep integration with the Russian and Iranian information ecosystems will continue to make it a target of Western policy attention.

For users, the practical impact of these tensions will probably be visible only at the edges: a few more banned channels, a few more advertising units, a slightly higher cost of being a power user. Telegram’s value, after all, was never about being the most private or the most regulated. It was about being the most flexible. As long as that flexibility persists, the next billion will probably arrive in the same way the first did — quietly, region by region, conversation by conversation.
