Tether dominates Binance, but Coinbase has just integrated USDC into Hyperliquid. The battle for stablecoin distribution channels is intensifying. Hyperliquid is currently the most fiercely contested battleground in crypto. Last week, 21Shares and Bitwise’s HYPE spot ETFs launched on U.S. exchanges, with Grayscale and VanEck following closely behind. Beneath this wave of institutional enthusiasm lies a protracted struggle for influence—everyone wants a piece of this exchange’s profits.

Last autumn, Hyperliquid launched an open tender for a native stablecoin called USDH, aiming to reclaim revenue lost to Coinbase and Circle. At the time, roughly $5.6 billion worth of USDC sat in the exchange’s cross-chain bridge, generating approximately $200 million in annual interest—profits that flowed entirely to its centralized competitors, while the platform actually driving demand received nothing. Ultimately, Native Markets won the community vote over rivals like Paxos and Ethena, and USDH officially launched.

Yet just last week, Native Markets sold USDH to Coinbase, agreeing to phase out the native stablecoin and reinstate USDC as the exchange’s primary quoting asset. In exchange, 90% of the revenue will flow back to Hyperliquid—though the precise revenue-capture mechanism remains unclear. This deal is widely interpreted as a victory for Hyperliquid—and a loss for Coinbase and Circle. That interpretation is understandable—but inaccurate.

The benefits Hyperliquid gains from this deal are clear: a significantly higher revenue share—roughly double what it earned under USDH; regulatory firepower by aligning with one of the most influential forces in crypto policy in Washington; and enhanced user experience from returning to a trusted stablecoin. After all, the exchange was originally built around USDC—and USDC dominated the HIP-3 markets that generated countless headlines for Hyperliquid over the past six months.

Coinbase’s and Circle’s move is seen as a reputational upgrade—a strategic alliance with one of the most crypto-native and successful projects of the last cycle. But if we overlay USDC’s real-world market positioning with the growth trajectory of perpetual futures, a second beneficiary emerges. Coinbase and Circle are gaining access to a massive USDC distribution channel—potentially the single most important element of the entire deal.

Since the GENIUS Act passed, USDC has demonstrated strong momentum. Circle had already prepared the regulatory environment for this framework: USDC is U.S.-based and highly compliance-focused. This positioning has translated directly into trading volume. Allium data shows USDC’s May 2026 trading volume reached $355 billion—surpassing USDT for the first time in recent months, signaling accelerated growth since the GENIUS Act’s July 2025 passage.

What hasn’t changed is the overall structural landscape. In April 2025—just before the GENIUS Act—USDT held 67% of the stablecoin market share, while USDC held 27.6%. A year later, USDT’s share stood at 67.3%, and USDC’s at 28.1%. The shift was merely half a percentage point. Although USDC’s trading volume is accelerating, its supply share remains stagnant.

An Artemis report from October last year noted that the U.S. is USDC’s strongest market. Combined with post-GENIUS growth trends, the U.S. has consistently served as USDC’s largest growth engine. Yet precisely this fact makes it the focal point of the next round of competition. Stripe has entered decisively—acquiring companies like Tempo. Major financial institutions are launching domestic stablecoins compliant with GENIUS standards. USDC’s home turf is being eroded from all sides.

Once domestic U.S. competition heats up, USDC has almost no fallback position overseas. Elsewhere, USDT reigns as the default dollar—widely used for savings, investment, and trading—and continues expanding aggressively. Over the past year, multiple new blockchains launched specifically to expand USDT’s distribution network, and Tether rolled out USAT to attack USDC within the GENIUS-compliant U.S. regulatory framework.

Perpetual futures are among crypto’s fastest-growing sectors—maintaining double- or even triple-digit year-on-year growth. Structurally, they’re deeply tied to stablecoins, which serve primarily as quoting assets for perpetual markets. USDT has already secured a dominant foothold here, acting as the primary quoting asset for most markets on Binance—the world’s largest perpetual futures exchange.

Although Hyperliquid’s trading volume pales in comparison to Binance’s, it is the largest on-chain perpetual futures exchange—commanding 30% of on-chain perpetual futures market share and controlling 46% of open interest. As of April 30, its volume stood at roughly 50% of Bybit’s, 30% of OKX’s, and 79% of Coinbase International’s. Despite still being in its early stages, Hyperliquid’s dominance in on-chain perpetuals grants it global influence comparable to Binance’s outside the U.S.

So why doesn’t Coinbase simply build its own perpetual futures product to establish this distribution channel? Because Coinbase operates under tight regulatory constraints—limiting both the number of customers it can serve and the markets it can launch. Hyperliquid, benefiting from a more permissive environment, reaches more regions—and holds advantages over both Binance and Coinbase that Coinbase simply cannot replicate. Thus, Coinbase and Circle have outsourced global expansion to Hyperliquid—while USDC rides along.

Tether is executing a similar strategy. Following the Drift vulnerability exploit in April, Tether pledged up to $147.5 million in recovery funding. That deal designated USDT as Drift’s settlement asset, established a Tether-backed USDT liquidity pool for designated market makers, and funded a trading incentive layer. Both sides in the stablecoin war see the same truth: perpetual futures are the decisive battlefield for stablecoins.

Overall, to capitalize on the momentum created by the GENIUS Act, Coinbase and Circle need broader distribution channels—and the Hyperliquid deal may be exactly what’s needed. It embeds USDC deep into the core of on-chain trading, places it squarely on crypto’s fastest-growing track, and—on scale—positions it to compete head-to-head with USDT and Binance. It may also represent a bet on the loosening of domestic regulatory boundaries. CFTC Chair Selig has explicitly stated his desire for perpetual futures to be offered domestically in the U.S., and passage of the CLARITY Act could guarantee just that. Reports this week indicate the SEC is preparing to do so.
