Circle raises $222M in private sale for its Layer 1 Arc token, backed by a16z and BlackRock

Circle, the company behind the USDC stablecoin, has raised $222 million in a private sale for the native token of its upcoming Layer 1 blockchain, Arc. The sale values the project at a fully diluted valuation of $3 billion, according to a report from CNBC. The round was led by a16z with a $75 million investment, and included participation from more than ten institutional investors, among them BlackRock, Apollo Fund, Intercontinental Exchange (ICE), SBI Group, General Catalyst, and Ark Invest.

Arc: A blockchain built for institutional finance and AI agents

Arc is designed as a Layer 1 blockchain tailored to support institutional-grade financial functions and the emerging economy of AI agents. Unlike many public blockchains that prioritize retail users or decentralized finance (DeFi) speculation, Arc’s architecture is being built with compliance, scalability, and institutional oversight in mind. This positions the network as a potential settlement layer for traditional financial assets and regulated digital securities.

The move marks a significant strategic shift for Circle. Historically known as a stablecoin issuer, the company is now expanding into full-stack blockchain infrastructure. By launching its own network and native token, Circle aims to capture more value from the ecosystem it already serves, while offering institutions a compliant on-ramp to blockchain-based finance.

Why this matters for the crypto industry

The participation of major traditional finance players such as BlackRock, ICE, and Apollo underscores a growing appetite for regulated blockchain infrastructure. These institutions are not merely investing in a token; they are signaling interest in a platform that could eventually support tokenized securities, cross-border settlements, and automated compliance through smart contracts.

For Circle, the Arc token sale provides both capital and strategic validation. The company now has the resources to build out its Layer 1 ecosystem while maintaining relationships with some of the world’s largest asset managers and exchange operators. The involvement of SBI Group also hints at potential expansion into Asian markets, where regulatory frameworks for digital assets are evolving rapidly.

Potential impact on the stablecoin market

Circle’s expansion into Layer 1 infrastructure could reshape its competitive position relative to Tether and other stablecoin issuers. By controlling both the stablecoin and the underlying settlement network, Circle may offer lower transaction costs, faster settlement, and integrated compliance tools — advantages that could attract institutional clients who have been hesitant to use public blockchains.

However, the move also introduces new risks. Operating a Layer 1 blockchain requires ongoing security audits, node management, and governance. Circle will need to demonstrate that Arc can maintain uptime and security comparable to established networks like Ethereum or Solana, while also meeting the regulatory expectations of its institutional backers.

Conclusion

Circle’s $222 million private sale for the Arc token represents a pivotal moment for the company and for institutional crypto adoption. By building its own Layer 1 blockchain, Circle is betting that the future of finance will run on compliant, scalable infrastructure — and that it can be the company to provide it. The involvement of a16z, BlackRock, and ICE adds credibility, but execution will determine whether Arc becomes a foundation for institutional crypto or another ambitious project that struggles to gain traction.
