DEX vs CEX: Decentralized Exchanges Hit a Record

The balance of power between centralized and decentralized platforms has reached a new milestone. In July 2026, DEX spot volume equaled nearly 24% of CEX volume, the highest since tracking began in 2019. The number is real. Its interpretation deserves a closer look: this record owes as much to the retreat of centralized platforms as to the strength of DEXs, and it lands at the worst possible time for European traders, in the middle of a regulatory shift.

A Record That Owes a Lot to the Retreat of Centralized Platforms

Let us frame the number first. The ratio published by The Block does not measure DEX market share; it compares decentralized spot volume against a basket of major centralized platforms. At 24%, it means DEXs handled a little under a quarter of CEX volume, not that they took a quarter of the market. A year earlier, that ratio hovered around 17%.

The nuance matters, because the gain comes mostly from the other side. CEX spot volume fell to a twelve-month low, near $670 billion, against an annual peak of $2.23 trillion. DEXs, for their part, set no absolute record: their volume actually dropped about 26% month over month. In other words, they grabbed a bigger slice of a shrinking pie. Coinbase and Gemini cut staff over the period, and part of the speculative volume drifted toward prediction markets, which appear nowhere in this ratio. The move still fits a deeper trend, underway since 2025, that of Hyperliquid closing in on the centralized giants.

Hyperliquid, the Showcase of On-Chain Derivatives

It is in derivatives that the shift is most striking. Hyperliquid, an order book running on its own blockchain, alone accounts for roughly 36% to 44% of decentralized perpetuals volume depending on the period. Its monthly volume moves between $170 and $245 billion in 2026, far ahead of dYdX or GMX. 

One point deserves correction, because the figure gets thrown around a lot: the sometimes-quoted threshold of more than $430 billion a month refers to the best month of the entire on-chain perpetuals market (summer 2025), not to Hyperliquid alone.

Behind these volumes lies a change in the market’s nature. Perpetual contracts backed by tokenized assets (stocks, commodities, indices) are gaining ground, at times rivaling Bitcoin. When a real-world asset trades on-chain, it almost always does so on decentralized infrastructure, volume that CEXs do not capture.

Trust, UX, Institutions: The Three Drivers

Why this shift? Three reasons combined.

Trust

The first is trust, or rather its absence. The collapse of FTX in November 2022 left scars, and every new security incident on a platform revives the old reflex: « not your keys, not your crypto ». 

Hence the rise of self-custody wallets, where the user keeps control of their assets instead of leaving them sitting on an exchange. Switzerland’s Tangem, for example, claims more than six million NFC cards produced and $61 million in 2025 revenue, up 102%. The trade-off is real: whoever holds their keys bears sole responsibility for them, and a lost key cannot be recovered.

User Experience

The second is user experience. DeFi is no longer reserved for insiders. Aggregators, simplified interfaces, near-instant listing of new tokens: the experience gap with a CEX has narrowed sharply.

Institutions

The third is the arrival of institutions. The tokenization of real-world assets, now past $20 billion in total value locked, draws traditional liquidity that mechanically heads toward decentralized venues.

In Europe, the Real Dividing Line Is Regulatory

Here is the angle most analyses miss. For a European user, the « CEX or DEX » question is being replaced by a blunter one: is the platform even allowed to serve me? Since 1 July 2026, MiCA’s transition period has closed. Only providers holding a CASP authorization may legally offer crypto services to EU clients, and ESMA explicitly urges investors to check that status in its CASP register before entrusting funds to a platform. As of late August 2026, a little over 300 firms were authorized, out of more than a thousand that operated before.

In practice, this reshuffles the deck. MEXC remains, globally, a very accessible platform, with deep liquidity and one of the widest token catalogs on the market. But it is not on ESMA’s CASP register as of mid-2026 and appears on the lists of platforms expected to restrict EU access. For an EU resident, the first step is therefore not to sign up, but to check your eligibility, a point on which France’s AMF has issued repeated warnings.

Self-custody wallets escape this constraint: holding your own keys is not a regulated service, so a tool like Tangem (10% off with code Milly10) stays available whatever your country. Hence an increasingly common setup: use an authorized platform to trade where you are allowed to, and move your assets into self-custody to hold them. « CEX versus DEX » gives way to « CEX and self-custody », each doing what it does best.

The real shift is not the announced death of centralized platforms. It is that « where to trade » now comes, in Europe, with « am I allowed to », and that a growing share of users answer both by splitting the roles: an authorized venue to trade, their own keys to hold. It remains to be seen how many platforms that left the European market return through the MiCA door, and whether centralized volume rebounds once the summer lull closes. MiCA’s review, opened in May 2026, will give a first clue.
