From Negotiation to Transaction: How Russia's B2B Marketplaces Grew to 2 Trillion Rubles Ahead of the Platform Law

Behind the consumer-marketplace boom that everyone can see, a quieter and arguably more consequential transformation is under way in Russia: business-to-business commerce is moving onto platforms. According to a study by HSE University (НИУ ВШЭ) prepared for the Association of Digital Platforms, the combined turnover of Russian digital platforms reached 18.3 trillion rubles in 2025 — the equivalent of 8.5% of the country's GDP — after growing sixfold in just four years. Inside that expansion sits a distinct B2B and B2G core: online sales of goods to companies and state bodies through marketplaces and web stores hit 2 trillion rubles in 2025, and under the baseline scenario drawn by the consultancy Strategy Partners the segment is set to exceed 3 trillion rubles by 2028.

What makes this story more than a market-sizing exercise is timing. From October 2026, a dedicated federal law on the platform economy enters into force, imposing uniform rules on large digital intermediaries for the first time. The government has also ordered a national marketplace development strategy to be ready by 2027, covering data standards, reference architecture, information security and the use of artificial intelligence. Market participants and academics interviewed by the business daily Kommersant argue that regulation could complicate operations even as it legitimises them — and that the deepest constraint on Russian B2B platforms lies not in technology but in the institutional architecture of procurement itself. This deep dive unpacks the numbers, the drivers, the law and the outlook, based on the July 7, 2026 Kommersant analysis and the research it cites.

An 18-trillion-ruble platform economy — and the 2 trillion inside it

The scale of the shift is easiest to grasp in three layers. The outermost layer is the entire platform economy: 18.3 trillion rubles of turnover in 2025, or 8.5% of GDP, after a sixfold increase over the previous four years. The middle layer is the B2B/B2G slice of online trade — sales to businesses and government agencies through marketplaces and online stores — which reached 2 trillion rubles in 2025 and, in the Strategy Partners baseline, climbs past 3 trillion rubles by 2028. The innermost layer is the corporate economy that feeds it: revenue of Russian B2B companies grew 45% in 2024 to 19.9 trillion rubles.

Russia's platform economy and B2B online trade: key figures cited in the source

Indicator	Value	Reference period
Turnover of Russian digital platforms	18.3 trillion rubles (8.5% of GDP)	2025
Growth of the platform economy	Sixfold	Four years to 2025
B2B/B2G online sales via marketplaces and web stores	2 trillion rubles	2025
B2B/B2G online sales, baseline scenario	Above 3 trillion rubles	By 2028
Revenue of Russian B2B companies	19.9 trillion rubles (+45%)	2024
Companies on the Kosmos platform	More than 1,300 from ~40 regions	2026

The causal chain runs from the bottom layer upward. Olga Klimova (Ольга Климова), associate professor at the Financial University under the Government of the Russian Federation, puts it bluntly: at that scale of transactions and product nomenclature, processing deals manually or through traditional sales channels is "physically impossible." A corporate sector that grows its revenue by nearly half in a single year cannot keep matching supply with demand through phone calls, spreadsheets and field salespeople — the platform becomes, in her formulation, a production necessity rather than a convenience.

The structural map of the segment is also becoming more defined. The Strategy Partners research distinguishes generalist business marketplaces — among them MaksMart (Максмарт) and the Kontur.Vitrina (Контур.Витрина) platform — from specialised B2B marketplaces built around particular industries and types of business interaction. On top of that, the largest consumer platforms are spinning up dedicated business-facing arms, converting their logistics, catalogue and payment infrastructure into B2B offerings. The result is a three-tier market: horizontal business marketplaces, vertical industry platforms, and B2B divisions of consumer giants.

Why business is moving onto platforms

Digitalisation meets changed expectations

The press office of the financial marketplace Sravni (Сравни) attributes the platforms' popularity first of all to the general digitalisation of business, and second to a shift in behavioural expectations. Years of consumer online shopping have built trust in electronic commerce among the people who now run procurement at companies: they order at home the same way they would like to order at work. For the platform's business partners, the draw is the ability to scale quickly and cut costs — a value proposition that becomes decisive when credit is expensive and margins are squeezed.

The supplier shock and the cost of sales

Vasily Alexandrov (Василий Александров), general director of the Victory reputation-management and business-analytics ecosystem, adds an economic explanation rooted in the shocks of recent years. The withdrawal of part of the foreign supplier base — including vendors from China re-routing their goods and Western producers exiting the market — forced companies to find replacements fast, and a marketplace turned out to be the most convenient way to locate a new partner. At the same time, maintaining a large in-house sales department became too expensive, so a natural share of purchasing migrated into digital channels. Platforms, in other words, absorbed two shocks at once: a supply-chain rupture on the seller side and a cost squeeze on the buyer side.

From negotiation to transaction

The qualitative change Klimova highlights is the conversion of inter-company communication from a negotiation format into a transaction format. Supply and demand are matched instantly and with all conditions attached, including financial and insurance instruments. Where a deal once required several rounds of negotiations between counterparties, it is now concluded almost automatically. That is not a cosmetic difference: it changes how companies staff procurement, how they budget for working capital, and how quickly a new supplier can be brought into the supply base.

The economics of a platform deal

Mikhail Boldyrev (Михаил Болдырев), senior lecturer at the Institute of Socio-Economic Sciences of the Russian State University for the Humanities (РГГУ), considers the reduction of transaction costs to be the principal economic effect of platforms. The list of operations that a marketplace folds into a single reproducible process is long:

• searching for a customer or a supplier;
• checking and qualifying the counterparty;
• agreeing and exchanging documents;
• organising logistics;
• arranging financing for the deal;
• handling claims and complaints work.

Each of these used to consume managerial time in proportion to the size of the company's network of contacts. On a platform they become standardised services, which is why Boldyrev stresses the effect on small business: previously a small supplier needed personal connections to reach large customers, whereas now the connection between enterprises of any scale is resolved through the platform itself. For the first time, a regional workshop can sit in the same qualified supplier pool as a national champion, provided it passes the platform's verification.

The operational layer matters just as much. API integration with corporate accounting systems updates prices, stock balances and order statuses automatically, in real time. As Alexandrov notes, this reduces manual work and errors, and — critically — removes dependence on any individual manager: the process lives in the system rather than in someone's head. For risk managers, that is the difference between a documented, auditable procurement trail and an informal practice that collapses when an employee resigns.

A regional case: the Kosmos ecosystem

The platform model is not limited to commercial operators. In Sverdlovsk Region, the B2B face of the platform economy is the Kosmos (Космос) ecosystem, run by the Development Corporation of the Middle Urals (Корпорация развития Среднего Урала, KRSU), an agency created by the regional authorities. Kosmos helps companies find partners, access state support measures and promote their products, alongside a range of other services. In 2025 the platform acquired federal status; today more than 1,300 companies from roughly 40 Russian regions work through it, and within the region's digital ecosystem it serves as the primary "data lake" on industrial enterprises. The case shows how regional governments are building platform infrastructure as an investment-attraction tool — a hybrid of marketplace, industrial registry and subsidy gateway.

October 2026: the platform law arrives

The regulatory frame hardens this autumn. From October 2026, the Federal Law "On Certain Issues of Regulating the Platform Economy in the Russian Federation" takes effect. It governs the relationships between operators of intermediary digital platforms — large marketplaces, service aggregators, taxi services and specialist-finding platforms — and their partners, meaning sellers and service providers, as well as the rights of users.

For the first time, the law introduces uniform legal rules for digital platforms that meet quantitative thresholds: an audience of at least 100,000 users together with turnover from 50 billion rubles, or a partner count of at least 10,000. The key obligations include:

• mandatory written contracts with partners that clearly state commission rates;
• defined responsibility of each party;
• a documented procedure for acceptance and return of goods;
• a mechanism for appealing fines and account blocks.

The government is not stopping there. Prime Minister Mikhail Mishustin (Михаил Мишустин) has ordered a marketplace development strategy to be prepared by 2027. It will set common requirements for data types, a reference platform architecture, information security and the use of artificial intelligence — and it will identify the industries where creating platforms with state participation would be most effective. KRSU describes the state's core tasks as supporting high-technology sectors tied to the platform economy and legislating the terms of its activity.

The industrial community is already positioning itself. At a June 17 round table of the Chamber of Commerce and Industry (ТПП) titled "The Platform Economy of the Real Sector," participants agreed to explore piloting industry-specific digital platforms that could operate within procurement rules; to develop a single approach to qualifying and "passportising" digital platforms; to integrate platform tools into national projects and state programmes; and to design state support measures and financial-investment mechanisms for platforms. Each of these lines is a potential market opportunity — and a potential compliance burden — for existing operators.

What still holds B2B platforms back

Procurement law built around procedures, not platforms

Boldyrev calls the absence of a coherent institutional architecture the main problem of the B2B-marketplace industry, and his first example is the real sector's dependence on state and quasi-state demand. A significant share of large industrial orders passes through the contours of Federal Laws 44-FZ and 223-FZ — and those regimes were designed around the procurement procedure, not around a platform model of execution. As a result, an industrial platform today cannot act as an independent, legally significant point of order placement and fulfilment; more often it works as a showcase, a matching service or a supplier pre-qualification tool. That, he argues, is precisely why Russia has not yet produced strong B2B platforms of industrial scale.

Trust, secrecy and data security

The second challenge is trust. In industry, a platform may carry drawings, design documentation, know-how and trade secrets between counterparties. That demands closed contours, access separation, operation logging and explicit operator liability for data preservation — capabilities that generic marketplaces were never designed to provide. Alexandrov confirms that demand for trust instruments, including counterparty assessment, is only growing. Boldyrev also draws a distinction worth keeping in mind: digitising B2B deals (electronic procurement, document flow, supplier search) is already well developed in Russia, but genuine industrial co-operation platforms covering the full cycle — from capacity selection to quality control, acceptance and settlement — are only emerging, and here the country visibly lags, which is why their development has become part of the strategic state agenda.

Three trends through 2030

Anna Larionova (Анна Ларионова), marketing director of the flexible-employment platform Ventra Go (Вентра Го), expects three trends to strengthen in the coming years:

1. Digital footprint and transparency. The growing weight of a company's verifiable online record — deliveries, reviews, compliance history — as the primary trust asset in B2B matching.
2. Industry-specific platforms. Growth of verticals tailored to concrete business tasks, rather than universal "classifieds boards" that list everything and guarantee nothing.
3. Data, forecasting and automation. A shift from manual management of time and resources toward data-driven planning; in this sense B2B platforms become part of the new operating infrastructure of business, helping companies move faster and stay more resilient in a changing market.

What this means for procurement and sales leaders

Taken together, the numbers and the regulation sketch a practical agenda for companies that buy and sell on platforms. For procurement teams, the 2-trillion-ruble B2B segment and the sixfold platform-economy growth mean that sourcing outside the platform channel increasingly forfeits price transparency and supplier breadth; the sensible posture is to formalise platform procurement now, while API integration and counterparty-verification tools mature. For suppliers, the platform law's written-contract and appeals requirements reduce — though far from eliminate — the asymmetry that made marketplace dependence risky; a documented commission structure and an appealable blocking mechanism belong in every supplier's risk assessment from October 2026.

For platform operators, the strategic question is whether to grow horizontally into another universal marketplace or vertically into an industry platform with qualification, certification support and closed data contours. The Chamber of Commerce and Industry's push for platform "passports" and the promised state strategy suggest that verticals aligned with national projects will enjoy both policy support and, potentially, state co-investment. And for the state, the tension flagged by market participants is real: the same law that legitimises the platform economy can, if thresholds and reporting obligations are calibrated clumsily, slow exactly the industrial co-operation platforms that the strategic agenda wants to see.

The bottom line

Russia's B2B marketplaces entered 2026 with a strong balance sheet of facts: a platform economy worth 8.5% of GDP, a 2-trillion-ruble business-online-trade segment heading past 3 trillion by 2028, regional ecosystems like Kosmos aggregating thousands of industrial companies, and a legal framework arriving in October. The gap between this trajectory and a full-fledged platform B2B economy runs through 44-FZ and 223-FZ procurement rules, data-security requirements and the still-immature market for trust instruments. Whoever closes that gap first — commercial marketplaces, regional platforms or state-participated verticals — will define how Russian industry buys and sells for the rest of the decade.
