The global stablecoin market experienced unprecedented explosive growth in 2024-2025. As of October, the total market capitalization of stablecoins has surpassed $300 billion, marking an annual growth rate of 82.9% from $166.3 billion at the end of 2024. This growth not only sets a new historical record but also signifies a fundamental shift for stablecoins from a peripheral speculative instrument to mainstream financial infrastructure.

Historic breakthroughs in the regulatory environment provided strong momentum for this growth: In July 2025, the U.S. GENIUS Act was formally signed into law, establishing the first federal-level stablecoin payment framework. Simultaneously, the EU's MiCA regulation came into full effect in December 2024, laying a solid foundation for the standardized development of the stablecoin industry.

While USDT and USDC still dominate, their combined market share has decreased from 91.6% to 83.6%. The stablecoin market is undergoing subtle changes, with emerging stablecoin projects rising rapidly, such as:

* Ethena's USDe reaching a market cap of $11 billion.

* PayPal's PYUSD surpassing a market cap of $2.76 billion.

* The RWA-backed stablecoin market size reaching $35 billion, with 46% annual growth.

Dedicated Stablecoin Public Blockchains: An Infrastructure Revolution

Traditional blockchains reveal significant pain points when handling stablecoin transactions: Ethereum's high gas fees often reach tens of dollars, with transaction confirmation times ranging from seconds to minutes; Tron, while having lower fees, faces centralization risks and technical limitations.

A new generation of dedicated stablecoin public blockchains has achieved a qualitative breakthrough through technological innovation. These blockchains generally support high throughput of 1000+ TPS, zero or very low fees, and sub-second transaction confirmation. More importantly, they design stablecoins as the native gas token, completely eliminating the impact of cryptocurrency price volatility on user experience.

* Plasma: Tether Ecosystem's Flagship Project: As a leading project in the field, Plasma raised a total of $75.8 million. Its core innovation is the Paymaster system, enabling truly zero-fee USDT transfers. After its testnet launch on September 25, 2025, its TVL quickly reached $5.3 billion.

* Stable: Institutional-Grade USDT Optimization Solution: Positioned as a "payment rail for the real world," Stable focuses on institutional USDT applications. It uses USDT as the native gas token and implements zero-fee P2P transfers via account abstraction.

* Arc: Circle's Exclusive Ecosystem: Developed by Circle, Arc is positioned as the "home for stablecoin finance," deeply integrated with the Circle ecosystem. It uses USDC as the native gas token, ensuring a predictable fee structure pegged to the US dollar.

In terms of financing scale and technical progress, Plasma holds a leading advantage due to Tether's ecosystem support and the earliest testnet launch. Stable builds differentiated competitiveness through its institutional focus and PayPal partnership, while Arc leverages Circle's compliance strengths and USDC ecosystem status.

Yield-Bearing Stablecoins: Innovative Yield Models

Yield-bearing stablecoins provide users with a yield experience surpassing traditional bank savings by embedding yield directly into the stablecoin itself.

* Ethena USDe: USDe's market cap skyrocketed from $86 million in January 2024 to $11.04 billion in October 2025, an astonishing increase of 13,750%, making it the world's third-largest stablecoin. Its technical innovation lies in using a delta-neutral strategy to maintain stability.

* Sky Ecosystem: The Sky ecosystem (formerly MakerDAO) has reshaped the decentralized stablecoin lending market through rebranding and product innovation. USDS, as a reward-bearing stablecoin, offers users a 4.75% annualized yield through the Sky Savings Rate mechanism.

Stablecoin Payment Infrastructure & AI Integration: Reshaping Global Finance

In 2025, the volume of cross-border payments processed via stablecoins reached $4.6 trillion, equivalent to over 50% of Visa's throughput. Stablecoins can reduce costs from the traditional 2-7% to 0.5-2%, saving 50-80% in high-frequency cross-border scenarios. Furthermore, settlement times are shortened from 3-5 business days to under 3 minutes.

* Payment Infrastructure Breakthroughs: Companies like BVNK and Stripe have made breakthroughs in payment infrastructure. BVNK's business saw strong growth in 2025, with annual processed transaction volume exceeding $20 billion. Stripe launched stablecoin subscription payment features and an Open Issuance platform for businesses.

* AI Integration - The Future of Finance: The rise of the AI agent economy has spawned payment protocols and infrastructure specifically optimized for AI agents.

* KITE AI: Aims to build the first Layer-1 blockchain optimized for the AI agent economy, featuring core innovations like an Agent Identity Resolution system.

* x402 Protocol: Redefines HTTP payment standards, enabling seamless, low-cost machine-to-machine payments, with settlement often under 2 seconds and gas fees below $0.0001.

Investment Outlook and Risk Assessment

Stablecoin sub-sectors are moving from concept to reality, from speculation to application. Among the emerging trends, dedicated stablecoin public blockchains show the clearest investment value. Enterprise-grade payment solutions benefit from improving regulations. AI integration applications, while early-stage, are suitable for investors with higher risk tolerance. Yield-bearing stablecoins present the most complex risk-reward profile.

Regulatory risk remains the biggest variable. While the GENIUS Act and MiCA provide a framework, specific implementation details are still evolving. Competition is intensifying as traditional finance giants like Stripe, Visa, and Mastercard enter the space.

Investing in new stablecoin avenues requires finding a balance between technological innovation, regulatory compliance, and market demand. As key projects launch in 2025 and regulatory frameworks clarify, this wave of stablecoin infrastructure upgrades could reshape the global payment landscape, potentially offering substantial returns for early participants.
