Resumen

Stablecoins are rapidly evolving from mere trading tools into critical global financial infrastructure, with a total market cap exceeding $310 billion and annual transaction volume reaching $33 trillion in 2026. This growth is driven by three key factors: clearer global regulations, increasing institutional capital (with $7.9 billion in cumulative funding and 44% YoY VC growth), and rising demand for borderless settlement amid geopolitical complexities. The market is dominated by USDT (58% share) and USDC, but competition is shifting toward capital efficiency, yield generation, and compliance. Major application areas include cross-border payments, DeFi lending, institutional settlement, and RWA tokenization. Regulatory frameworks like MiCA in the EU and emerging U.S. federal rules are shaping the industry’s evolution, emphasizing transparency, asset backing, and compliance. Despite risks such as smart contract vulnerabilities and regulatory challenges, the ecosystem demonstrates resilience. Stablecoins now form a full-stack infrastructure, spanning reserve assets, issuance, multi-chain liquidity, and end-use cases in payments, social platforms, and AI-driven transactions. The future lies in their role as a default settlement layer for the global digital economy.

Stablecoins are evolving from trading tools into global financial infrastructure.

For a long time, the market's understanding of stablecoins was largely confined to their role as a "cryptocurrency trading medium": they were used for exchange quotations, served as on-chain hedging tools, or acted as basic liquidity assets within the DeFi system. However, entering 2026, this narrative is being rapidly rewritten. The functional boundaries of stablecoins have expanded from "auxiliary trading assets" to payments, settlements, collateral, yield generation, cross-border clearing, and even RWA settlement layers, gradually evolving into a key piece of infrastructure within the global digital financial system.

CoinFound's latest research, "Stablecoin Ecosystem Map — From Trading Tool to Global Financial Infrastructure," points out that the stablecoin market is entering a new phase characterized by "high mainstream adoption and high institutionalization." Its significance is no longer limited to price stability or on-chain circulation efficiency, but lies in its ability, through programmability, global settlement capabilities, and multi-chain liquidity networks, to become a crucial bridge connecting traditional finance with the decentralized ecosystem.

Stablecoin Market Has Entered a Trillion-Dollar Normalization Cycle

In 2026, the total market capitalization of the global stablecoin market has exceeded $310 billion, with annual trading volume reaching $33 trillion. This figure alone is sufficient to demonstrate that the practical application scenarios of stablecoins have long surpassed internal circulation within cryptocurrency exchanges and are extending into the broader real economy and global fund clearing networks.

From a market evolution logic perspective, stablecoins are no longer just "dollar substitutes" on-chain but are taking on a deeper infrastructure function:
They are both a carrier for cross-border value transfer and an underlying liquidity engine for the DeFi and RWA systems, while also being gradually embedded into payment gateways, corporate treasury management systems, and the backend clearing structures of social networks.

Particularly noteworthy is the significant growth in the Asian market. The market capitalization of stablecoins on BNB Chain achieved a 133% year-on-year expansion in the past year. This trend indicates that the stablecoin ecosystem is not only deepening its integration within the European and American financial systems but is also forming new regional payment and clearing networks in the Asian market.

Three Macro Drivers Jointly Propel Stablecoin Acceleration

The underlying logic driving the rapid upgrade of the stablecoin ecosystem comes mainly from three aspects:

First, Regulatory Clarity.
Major jurisdictions worldwide are gradually establishing compliant frameworks for stablecoins. Clear regulations not only reduce policy uncertainty but also provide the prerequisite for large-scale institutional capital entry. In the past, many traditional financial institutions were cautious about stablecoins not because they disapproved of their efficiency, but due to the lack of a clear legal framework. Now, this obstacle is being gradually removed.

Second, Sustained Inflow of Institutional Capital.
As regulatory boundaries become clearer, investments from VCs, asset management institutions, and traditional financial companies into stablecoins and their related payment infrastructure continue to expand. According to data in the article, this sector has cumulatively absorbed $7.9 billion in institutional funding, with VC investment showing an annualized growth rate of 44%. This means the stablecoin track is no longer just a battlefield for Crypto Native entrepreneurs but is becoming a core direction for active allocation by traditional capital.

Third, Geoeconomics and Global Clearing Demand.
Complex international environments, cross-border payment frictions, and the normalization of traditional financial sanctions have objectively increased the demand for alternative clearing networks. The borderless liquidity and 24/7 settlement capabilities inherent to stablecoins give them a natural advantage in this trend. Phenomena like capital migration in extreme scenarios also validate the real demand for stablecoins as a global liquidity network.

Global Regulatory Frameworks Are Reshaping Industry Boundaries

Entering 2026, the regulatory environment for stablecoins is moving from localized pilots to systematic implementation.

In the United States, a federal-level framework is taking shape, focusing on 1:1 high-liquidity asset reserves, strict auditing, and inclusion under national bank supervision. Simultaneously, the debate over "whether yield-bearing stablecoins should pay interest" has become a key watershed for industry development.
This debate essentially questions whether stablecoins should be treated as "payment tools" or could evolve into "shadow deposits" or deposit-like financial products.

The EU's MiCA has been fully implemented, imposing strict constraints on stablecoin reserve segregation, whitepaper disclosure, and interest payments, reflecting a highly cautious regulatory logic.

Hong Kong is accelerating the layout of its local stablecoin licensing system, emphasizing local registration, 100% cash or US Treasury backing, and attempting to seize the institutional high ground as an Asian hub for RWA and digital finance.

The UK is also promoting regulatory integration for "systemically important stablecoins," bringing them into the traditional financial services act system.

This means the global stablecoin ecosystem is no longer in a "regulatory vacuum" but is forming a clear policy map.
This map, on one hand, boosts institutional confidence, and on the other, imposes higher requirements on yield-bearing stablecoins, DeFi protocols, and RWA product structures. Future competition will not only be about technology and scale but also about compliance capability, product segregation capability, and policy adaptation capability.

Market Structure Diverges: USDT and USDC Maintain Dominance, Yield and RWA Rise Rapidly

In terms of competitive landscape, the stablecoin market shows clear signs of top-heavy concentration and structural divergence.

Tether (USDT) still maintains a dominant position with a market share of approximately 58%, having built a deep liquidity moat in offshore trade and emerging markets.
Circle (USDC), leveraging its compliant image, institutional channels, and Ethereum ecosystem advantages, continues to increase its share in regulated markets, with its market share rising by about 7%.

Meanwhile, competition among issuers is no longer limited to "whose stablecoin is bigger" but has extended to capital efficiency, yield generation capability, and underlying collateral structure:

Tether is challenging the institutional market through more compliant product structures;
Besides USDC, Circle is also enhancing its appeal to institutions through yield-bearing and tokenized fund products;
Tokenized treasury products like BlackRock's BUIDL are becoming an important component of the underlying interest-bearing collateral for various DeFi protocols and stablecoins.

This change signifies that stablecoin competition has escalated from "payment tool competition" to "financial infrastructure competition." Those who can provide higher capital efficiency, stronger compliance, and deeper institutional synergy will be more likely to lead the next phase of ecosystem evolution.

Sub-sectors: Payments, DeFi, Institutional Settlement, RWA All Accelerating

From an application perspective, the current stablecoin ecosystem exhibits several distinct growth directions.

1. Cross-border Payments and Remittances

Payments and remittances remain one of the core real-world use cases.
Especially in B2B scenarios, stablecoins have become an important tool for restructuring cross-border payment efficiency. Compared to the multi-layer correspondent bank clearing in traditional financial systems, stablecoins offer obvious advantages in cross-timezone, low-cost, 24/7 settlement.

2. DeFi Lending and Yield Generation

Stablecoins have evolved into benchmark interest rate assets in DeFi.
The rise of yield-bearing stablecoins means they are no longer just safe-haven assets but also capital management tools兼具 (jùbèi - possessing both) payment and yield attributes. This change is highly attractive to both users and institutions and has been a major reason for the market's rapid growth in recent years.

3. Institutional Settlement and Backend Clearing

Traditional payment networks are gradually introducing blockchain backends.
The penetration of stablecoins in institutional settlement means they are not just on-chain assets but are progressively becoming the "invisible clearing layer" behind traditional payment systems.

4. RWA Tokenization and Underlying Liquidity Integration

RWA is one of the most noteworthy long-term trends currently.
As traditional financial assets are gradually tokenized, stablecoins or similar yield-bearing products will increasingly assume the role of the cash leg and collateral asset in transactions.
The combination of stablecoins and RWA is expanding the on-chain world from speculative finance to the more real and vast traditional capital markets.

Risks Persist, But the Market Shows Anti-Fragility

Although the stablecoin market is entering a mature phase, underlying risks have not disappeared.

The article broadly categorizes the risks into three types:

Operational and Technical Risks: Smart contract vulnerabilities and cross-chain bridge attacks remain major concerns
Market and Liquidity Risks: DeFi leverage models and volatility of underlying collateral assets could trigger de-pegging pressure
Geopolitical and Scrutiny Risks: The use of offshore stablecoin networks in global capital flows may further trigger AML and compliance regulatory upgrades

Additionally, yield bans are creating new compliance friction for DeFi protocols; and the scaled expansion of RWA highly depends on legal配套设施 (pèitào shèshī - supporting facilities) like offline title confirmation and bankruptcy remoteness.

However, it is noteworthy that the market has not lost resilience because of these risks. On the contrary, after experiencing periodic volatility, the stablecoin ecosystem has demonstrated极强的 (jí qiáng - extremely strong) self-healing capabilities. After short-term deleveraging and sentiment shocks, capital flows back, indicating that the market's long-term judgment of the value of stablecoin infrastructure has not wavered.

Stablecoins Are Forming a Full-Chain Closed-Loop Ecosystem

From an industry chain perspective, stablecoins are no longer an isolated asset but have formed a complete closed loop from upstream to downstream:

Upstream: Reserve assets, government bonds, regulated RWA
Midstream: Issuance, custody, cross-chain routing, multi-chain liquidity networks
Downstream: Payments, settlement, DeFi, RWA, social payments, AI-driven scenarios

This full-chain closed loop意味着 (yìwèizhe - means that) stablecoins are upgrading from a single financial product to an extensible, composable, embeddable global value transfer network.

Future innovation directions worth focusing on include:

Stablecoin payment integration within social platforms
Compliant stablecoins pegged to regional fiat currencies
AI Agents-driven machine-to-machine payments
Lower-barrier fiat on-ramps and account abstraction technology

These trends indicate that the future of stablecoins is not just "more people holding them" but "more systems adopting them as the default payment and clearing layer."

Conclusion: From On-Chain Dollars to Global Financial Rails

The stablecoin industry is undergoing a fundamental identity transformation.
It is no longer just a convenient tool in the Crypto market but is evolving into a global financial infrastructure covering payments, clearing, yield, collateral, and asset settlement.

From regulatory clarity to institutional entry; from solidified top-tier格局 (gèjú - landscape) to the rise of RWA and yield-bearing products; from expanded payment scenarios to integration with social networks and AI protocols, the next phase of the stablecoin ecosystem will clearly not be about point breakthroughs, but systematic evolution.

For investment institutions, fintech companies, policymakers, and Web3 builders, understanding stablecoins is no longer just about understanding one sector, but about understanding the underlying architecture of the future digital financial world.

Annual Salary of Millions Competing for Electricians, Meta Rushes to Open Its Own Technical School

The AI boom is facing an unexpected bottleneck: a severe shortage of skilled construction workers and electricians. As tech giants like Meta, OpenAI, and Alphabet race to build massive data centers—such as OpenAI's $16 billion "Stargate" project—they are hitting a critical labor wall. The U.S. needs an estimated 130,000 more electricians, 240,000 construction workers, and 150,000 supervisors by 2030 for AI infrastructure alone, but tens of thousands of electrician jobs go unfilled each year. While AI companies offer high premiums, with electricians earning up to $280,000 annually, worker scarcity still causes massive losses—delays on a single project can cost $14.2 million per month. The complexity of building AI data centers, which require immense power (equivalent to powering hundreds of thousands of homes), sophisticated electrical systems, and advanced liquid cooling solutions, demands highly skilled technicians who are in short supply. To combat this, companies are investing heavily in training. Meta has committed $115 million to a free training school offering tuition, housing, and stipends, targeting 5,000 new workers. OpenAI is partnering with unions to secure skilled labor. These efforts are paying off, with a significant rise in Gen Z interest in trade schools over college. However, the power demands are staggering. AI data centers are driving a rapid surge in electricity consumption, projected to account for up to 12% of U.S. power use by 2028 and raising costs for consumers. Furthermore, the construction boom is project-based, leading to a potential future glut of trained workers once building peaks, which could depress wages industry-wide. The race for AI supremacy now depends as much on skilled hands as on advanced chips.

OpenAI No Longer Sells Its Most Expensive Model for Profit

OpenAI is shifting its business strategy away from promoting its most expensive, flagship models for every task. Recent price cuts—80% for GPT-5.6 Luna and 20% for Terra—signal a deeper change: the company now actively advises users that many tasks don't require the most powerful model. Instead, OpenAI recommends a tiered approach: use the high-end GPT-5.6 Sol for complex planning and analysis, then delegate execution to cheaper models like Luna. This mirrors moves by Anthropic, which recently launched Claude Opus 5 at half the price of its top model, Fable 5. Both companies are de-emphasizing flagship models as primary revenue drivers, using them instead for brand prestige and technological showcases. The industry is entering a "mass-market" phase, similar to automotive, where high-volume, cost-effective models handle daily operations and drive scale. OpenAI's price reductions are partly enabled by AI models themselves optimizing underlying code and infrastructure, creating a self-reinforcing cycle of efficiency gains and cost reduction. Competition is shifting from "who is smartest" to "who offers the best value." The goal is no longer selling individual models but fostering widespread API adoption and ecosystem lock-in. By making AI calls cheap and ubiquitous, companies like OpenAI aim to become the indispensable, utility-like infrastructure powering automated workflows—the "water and electricity" of software, quietly embedded everywhere.

Suspected 4th Coldcard attack wave sweeps 389 Bitcoin: Galaxy’s Thorn

Coldcard hardware wallet users are facing a new wave of coordinated attacks targeting a firmware flaw, with researcher Alex Thorn flagging 218 recent transactions moving approximately 389 Bitcoin from potentially impacted addresses. The attack pattern shows a high rate of transactions targeting unique victim addresses, differing from previous waves. The vulnerability, which causes affected devices to generate weaker wallet seeds, is estimated to have impacted over 1,100 wallets, leading to around $90 million in Bitcoin stolen. Thorn advises affected users who control their keys may attempt to move funds with a higher-fee transaction before the attacker's transactions are confirmed.

Bitcoin Miners Are Waving the White Flag, But Their Stocks Are Soaring

Bitcoin miners are capitulating as evidenced by a sustained drop in network hash rate and a record-steep 19.9% decline in mining difficulty, signaling the shuttering of unprofitable machines. However, in a significant divergence from historical patterns, the stocks of publicly traded mining companies have soared, with one major player gaining over 430% in the past year, even as BTC's price fell roughly 46%. This surge is largely attributed to these companies pivoting toward the more lucrative AI narrative. Simultaneously, miners face a structural squeeze. Daily block reward revenue in BTC terms has hit a new all-time low following the latest halving, with current dollar-denominated daily revenue around $30 million compared to a longer-term average of ~$40 million. Fee revenue remains negligible, covering less than one block's subsidy over a 28-day average and accounting for only about ten minutes of the network's daily security budget. This capitulation cycle is unique: miner stress and crypto price weakness have decoupled due to alternative revenue streams (AI), while the long-term reliance on increasing bitcoin prices to offset shrinking subsidies continues, with fee income still far from filling the impending gap.

Will the Fed Definitely Raise Interest Rates in September? How Will Crypto and U.S. Stocks Withstand the Pressure?

The market's expectation for a September Fed rate hike surged dramatically in early August, jumping from under 50% to over 80% within a week. This shift followed a contentious July FOMC meeting, where a 9-3 vote to hold rates revealed growing dissent from hawkish members advocating for an immediate hike to combat persistent inflation. The primary catalyst for this repricing is rising oil prices, driven by renewed geopolitical tensions around the Strait of Hormuz, which threaten global supply. Energy costs directly influence inflation metrics, making the upcoming July CPI report (due August 12th) a critical data point. If it shows inflation reaccelerating, the probability of a September hike will solidify. For Bitcoin and crypto assets, this is typically bearish news. Bitcoin continues to behave as a high-beta, liquidity-sensitive risk asset. A rate hike raises the opportunity cost of holding non-yielding assets and could drive capital toward money markets, pressuring crypto prices in the short term. However, historical patterns suggest that if a hike is perceived as the end of a tightening cycle rather than the start, any negative price impact may be brief. U.S. stocks, particularly crypto-linked equities like Coinbase and growth-oriented tech stocks, are also vulnerable. Higher rates increase discount rates in valuation models, putting pressure on high-multiple companies. This coincides with a pivotal tech earnings season where investor focus has shifted from massive AI capital expenditure to tangible revenue and cash flow generation. Companies with negative cash flow and weak growth narratives could face heightened volatility if borrowing costs rise in September. In summary, a September Fed hike has evolved into a mainstream market scenario. Key factors to watch are oil prices, the July CPI report, and Fed communications, which will determine the final decision and its impact on volatile crypto and equity markets.
