According to CoinDesk, the U.S. SEC has launched a five-year innovation exemption that provides a pathway for eligible tokenized U.S. stocks to be traded through automated market makers (AMM) on public blockchains. Analysts from Goldman Sachs and Citizens believe that Coinbase, Robinhood, and Circle could become early beneficiaries of this policy.The new framework requires tokens to retain shareholder rights such as dividends and voting rights while imposing limits on the number of stocks and trading volume that trading platforms can offer. Goldman Sachs stated that Coinbase's existing tokenized stock products already possess several of the required features, and its institutional custody business and Coinbase Tokenize may also benefit.However, Coinbase's current trading platform uses a centralized limit order book, and to operate a trading venue directly under the exemption, it will still need to build AMM infrastructure or route trades to decentralized trading platforms on Base.Currently, the stock tokens offered by Robinhood for markets outside the U.S. are derivatives that only provide price exposure and do not possess the complete shareholder rights required by the framework, thus requiring further adjustments to the product. Robinhood has previously stated plans to add 1:1 redemption and voting rights features for stocks.Analysts also believe that an increase in on-chain securities trading may drive demand for tokenized cash, benefiting Circle indirectly, with USDC potentially being used for settlement and collateral in on-chain markets.

Circle's public chain Arc has officially announced that it has launched proxy payments.Its Facilitator Service provides a hosted access path for x402 developers, allowing the acceptance of USDC and supporting on-chain settlements on Arc, Base, and Polygon; this path does not require a Relayer key or a separate Gas fee wallet.

According to monitoring by Bubblemaps, Circle has completed the minting of 10 billion ARC tokens and distributed them to 11 addresses via a null address, which can now be tracked in real-time on the blockchain.The Arc team previously announced that the minting of ARC tokens has been completed, with a total of 10 billion tokens. The team emphasized that ARC tokens are not yet available for circulation, trading, public use, or activation for staking, governance, fees, or utility functions. According to the previous white paper, the distribution plan for ARC tokens is as follows: 60% allocated to the ecosystem (token sales, developer funding, network growth); 25% allocated to Circle (protocol development, staking, and governance); 15% allocated to long-term reserves (strategic flexibility and economic stability).

Circle co-founder and CEO Jeremy Allaire posted on the X platform that the Circle x402 Facilitator service has launched on Arc, which supports the settlement of USDC on Arc, Base, and Polygon PoS through EIP-3009.In addition, with the launch of Arc, the market demand for cirBTC is increasing. Currently, Circle Mint customers can directly mint and redeem cirBTC natively within the app, with each cirBTC backed 1:1 by 1 native BTC and redeemable for native BTC at a 1:1 ratio.

ARK Invest crypto analyst Lorenzo Valente stated that stablecoins have a significant network effect. Although there are thousands of stablecoins in the market, as the market capitalization threshold increases, the number of tiers is rapidly leveling off. Currently, the stablecoins that are truly worth paying attention to are those with a market capitalization exceeding 10 billion dollars, gradually moving towards the 100 billion and 500 billion dollar levels.Data shows that the number of stablecoins with a market capitalization exceeding 1 billion dollars has only increased from single digits to the current 12 since 2021, while the number of stablecoins with a market capitalization exceeding 10 billion dollars has actually decreased from its peak in 2022, with only Tether and Circle's stablecoins remaining. Valente believes that entering the 10 billion dollar market capitalization club has become very difficult, and in the future, the 100 billion dollar level stablecoins may only have two competitors for a long time, while it may take more than two years for only one to reach the 500 billion dollar level.
