Who Owns the AI Agents? Centralized vs. Decentralized AI in Web3

The True Owners of AI Agents

By 2030, the AI agent market is projected to surpass $50 billion globally, with millions of autonomous agents expected to manage tasks across finance, marketing, development, and governance. In Web3 alone, over 1 million AI agents could be live by the end of 2025, reshaping the way decentralized systems operate. But while adoption is accelerating, a core question is coming into focus: who actually owns—and controls—these agents?

As big tech companies like OpenAI and Google race to define the future of intelligent automation, Web3 is offering a radically different approach. Instead of centralized infrastructure, closed-source models, and corporate control, decentralized AI agents are emerging that operate transparently, autonomously, and collectively on-chain.

In this article, we'll dive into the differences between centralized and decentralized AI agents, explore how each model impacts user control and system design, and examine what's at stake as autonomous agents become active participants in the Web3 economy.

Big Tech's Push for AI-Controlled Finance

The rise of AI agents in Web2 has largely been driven by centralized tech giants. Companies like OpenAI, Google, Microsoft, and Amazon are deploying increasingly autonomous AI assistants to control workflows, user interactions, and, in some cases, digital assets. From Microsoft's Copilot and IBM's Watsonx Orchestrate to Amazon's Bedrock agents, the industry is rapidly standardizing AI-powered productivity solutions across enterprises.

This top-down approach to AI is shaping the future of finance and work, but it comes at a cost. Centralized AI models are typically black boxes—closed-source systems that rely on massive datasets harvested from users, often with minimal transparency. In these frameworks, the user has little control over the AI agent's behavior, data retention, or even alignment with personal or organizational goals.

More importantly, centralized AI consolidates power in the hands of a few companies. With data, models, and computational infrastructure under their control, these corporations effectively gatekeep access to intelligence at scale. If unchecked, this dynamic could turn AI into a tool that reinforces centralized economic and informational hierarchies rather than disrupting them.

The Promise of Open-Source and Decentralized AI Agents

Decentralized AI agents present an alternative vision—one that aligns more closely with the values of Web3. Unlike their Web2 counterparts, Web3-native AI agents operate autonomously on-chain, interact with smart contracts, manage wallets, and make decisions based on transparent, verifiable logic. These agents don't just serve users; they become users themselves—interacting with crypto markets, DAOs, and DeFi ecosystems in real-time.

One of the clearest examples of this new trend is the rise of projects like Virtuals Protocol and daos.fun. These platforms allow users to spin up AI agents with their own on-chain identities, wallets, and tokens. Some agents, like G.A.M.E or Luna, engage with communities as influencers, traders, or digital performers. ElizaOS (formerly ai16z), on the other hand, operates as a DAO-managed hedge fund, automatically optimizing portfolios using on-chain signals and decisions modeled after a16z co-founder Marc Andreessen.

ChainGPT's Nova AI News Agent exemplifies how Web3 AI can deliver value without relying on centralized infrastructure. Nova searches blockchain networks, social media platforms, and trusted news sources, publishing real-time market updates, insights, and educational content autonomously on X. Because it harnesses the power of the blockchain, Nova operates with a level of transparency, decentralization, privacy, and autonomy that centralized tools like ChatGPT or Gemini can't replicate.

In contrast, traditional AI tools remain siloed. Even the most advanced LLMs, such as GPT-4.5 or Claude 3.7 Sonnet, still rely on user prompts and are typically disconnected from decentralized applications. While they can assist with tasks, they don't take action autonomously in trustless systems. Web3 AI agents, by design, are built to plan, execute, and improve based on feedback—without requiring user input at every step.

Decentralized artificial intelligence also introduces the potential for collective ownership and governance. With Web3 AI agents like aixbt and Asym, it is possible for communities to co-own agents, vote on governance matters, and benefit from agent-generated revenue. This flips the script on centralized SaaS models, where users are locked into subscriptions without any stake in the underlying service or data.

But perhaps the most compelling feature of decentralized AI agents is their ability to align incentives. By tokenizing the agents themselves, developers can create economic feedback loops that reward useful, aligned behavior—much like a DAO rewards active governance. Instead of relying on corporate terms of service, these agents follow smart contract logic and evolve based on community input and token-driven incentives.

Privacy and data control also take on a new dimension in the decentralized AI space. Because these agents operate on-chain, user interactions and decision-making processes are publicly verifiable and governed by smart contracts—not black-box APIs. This gives individuals greater control over their data and ensures that AI behavior is aligned with transparent logic, not opaque corporate algorithms.

Decentralized AI agents are also far more resilient by design. Without a centralized server or company acting as a gatekeeper, they're not vulnerable to single points of failure, censorship, or arbitrary shutdowns. Once deployed, these agents can operate autonomously, governed by code and maintained by their communities—ensuring long-term stability and uptime even under adversarial conditions.

The Challenges of Fully Decentralized AI: Computing, Trust, and Bias

While the promise of decentralized AI agents is exciting, it doesn't come without challenges. Building fully autonomous agents that are decentralized, trustworthy, and scalable remains a complex technical problem. Below, you can find the most significant roadblocks faced by Web3 AI agents:

  • Limited Scalability: Running AI agents directly on-chain is still limited by blockchains' throughput and the cost of computation. Most projects offload the heavy lifting to off-chain LLMs and then rely on cryptographic proofs or trusted execution environments to verify results. But these setups aren't yet fully decentralized. Scaling AI agent ecosystems to support millions of concurrent actions—without compromising decentralization—remains a long-term hurdle.
  • The Question of Trust: Without central moderation, how do we ensure agents act in ways that are safe and beneficial? While smart contracts provide transparency, there's still a lack of mature verification mechanisms for multi-step AI reasoning. Techniques like zero-knowledge proofs and verifiable computation are promising but not yet widely adopted. Until then, users must either trust the developer's code or risk malicious behavior from rogue agents.
  • Agent Bias: Even in decentralized systems, the models themselves are often trained on centralized data. This means AI agents can still inherit and amplify the same social, economic, or political biases embedded in traditional LLMs. Web3 alone can't solve this—it requires deliberate design choices, diverse training data, and community-driven feedback to make AI agents more equitable and inclusive.

The Path Towards a Decentralized Future for AI Agents

As AI agents become more powerful and autonomous, the question of who controls them will only grow more urgent. Centralized models may offer convenience and performance, but they come with tradeoffs—opaque decision-making, limited user control, and the concentration of power in the hands of a few dominant players. Without alternatives, the future of AI could reinforce existing hierarchies rather than empower individuals.

Decentralized AI agents offer a compelling counter-narrative. Built on transparent smart contract logic, governed by communities, and aligned through tokenized incentives, these agents reflect the core ethos of Web3. They unlock new possibilities in finance, content creation, governance, and beyond—without compromising on user sovereignty, privacy, or resilience.

The path forward won't be without its challenges, from scaling decentralized infrastructure to minimizing bias in artificial intelligence models. But as tools and frameworks mature, Web3 AI agents have the potential to form the foundation of the agentic web, where AI works with users, not above them.
