The Infrastructure for Agent Identity represents a foundational layer for the next generation of autonomous AI systems and multicloud, multi-agent ecosystems. As AI agents assume greater autonomy in enterprise workflows, customer interactions, and cross-border data exchanges, the need for a portable, auditable, and privacy-preserving identity fabric becomes a strategic prerequisite for trust, scale, and regulatory compliance. This report frames agent identity as a distinct yet interoperable market vertical within the broader identity and access management (IAM) stack, with a focus on cryptographic identity primitives (such as decentralized identifiers and verifiable credentials), policy-driven governance, and provenance-enabled trust networks. The surge in AI agent deployment across financial services, healthcare, manufacturing, and logistics—coupled with stringent data protection regimes and the rising proficiency of adversarial actors—is accelerating investment in the infrastructure that allows AI agents to prove who they are, what data they can access, and why their actions are permissible. The investment thesis rests on three pillars: (1) standardization and interoperability will unlock network effects and reduce integration friction; (2) privacy-preserving identity techniques will align with regulatory demands and consumer expectations; and (3) modular, auditable identity layers will enable faster time-to-value for enterprise AI programs, reduce risk, and create defensible moats around platform-native intelligence layers. While the opportunity is expansive, true monetization will hinge on the emergence of trusted ecosystems—where insurers, regulators, cloud providers, and AI platforms anchor shared identity infrastructures and governance protocols—rather than isolated point solutions.
Market participants should monitor three catalytic trajectories: first, the maturation and adoption of W3C and community-driven standards for decentralized identifiers (DIDs), verifiable credentials (VCs), and DID Communication (DIDComm) that enable portable agent identities across heterogeneous environments; second, the deployment of privacy-preserving technologies—such as zero-knowledge proofs and selective disclosure mechanisms—that reconcile agent autonomy with regulatory constraints and consumer privacy; and third, the development of governance, attestation, and revocation frameworks that provide auditable behavior histories and risk management for high-stakes AI operations. The confluence of AI agent proliferation, regulatory scrutiny, and the need for interoperable, trust-enabled ecosystems creates a multi-year structural growth runway for the infrastructure layer of agent identity, with meaningful upside potential for incumbents and credible opportunities for specialized startups that can deliver integrated, scalable, and privacy-conscious identity platforms.
Today’s IAM market is dominated by role-based access control, single sign-on, and cloud-native identity services offered by large platform vendors. This server-centric paradigm, while effective for human users and traditional workflows, reveals a friction gap when deployed at scale for autonomous AI agents that operate across devices, edge environments, data silos, and partner networks. Agent identity requires a shift from static credentials to dynamic, cryptographically verifiable attestations that can travel with an agent across domains, while preserving privacy and enabling continuous policy enforcement. The technical core of this shift lies in decentralized identity constructs: DIDs provide self-sovereign, portable identifiers, while VCs enable verifiable, cryptographically signed attestations about an agent’s capabilities, provenance, and permissions. The sea change is not merely cryptographic; it is architectural, governance-oriented, and regulatory-driven. Agents need trust anchors that are auditable by humans and regulators, not just deterministic access controls inside a single organization’s perimeter. This implies a new ecosystem of identity wallets, trust registries, policy engines, and interoperability layers that connect cloud, on-premises, and edge environments in a secure, privacy-preserving manner.
The standards trajectory matters. The W3C Verifiable Credentials and Decentralized Identifiers specifications have matured to a level where cross-organization issuance, revocation, and verification are technically feasible at enterprise scale. However, widespread adoption depends on robust interoperability layers, governance models, and proven performance in latency-sensitive enterprise workflows. Beyond technical standards, governance constructs—attestation authorities, revocation registries, and compliance verified by trusted third parties—become the currency that institutions rely on when entrusting AI agents with sensitive operations. Regulatory regimes across data protection, financial crime, and sector-specific requirements exert a strong influence on design choices, shaping whether the market leans toward self-sovereign identity models or hybrid, regulated implementations with centralized trust anchors. In parallel, the rise of privacy-preserving computation and zero-knowledge proof (ZKP) techniques offers a pathway to reconcile agent autonomy with disclosure controls, enabling agents to demonstrate compliance or capability without exposing sensitive data.
The economic logic driving investment is clear. Enterprise AI initiatives struggle without reliable identity rails that guarantee agent accountability, traceability, and access governance. The cost of misattribution, data leakage, or non-compliance scales quickly in regulated industries. Conversely, a robust agent-identity infrastructure can reduce onboarding friction, accelerate vendor and data collaboration, and improve the accuracy of agent-driven decisions by ensuring that agents operate within sanctioned policy envelopes. The result is a market that rewards platforms and services capable of delivering interoperable identity fabrics, secure attestation workflows, and privacy-centric governance—elements that enable scalable, auditable AI deployment across complex ecosystems.
First, identity is becoming the new security perimeter for AI agents. As agents perform increasingly consequential tasks—executing trades, assisting in clinical decision support, managing supply chains, or negotiating service-level agreements—their actions must be traceable to an auditable identity with a defensible provenance. This shifts the investment tone toward infrastructure that emphasizes verifiable claims, dynamic policy enforcement, and tamper-evident event logging. The market rewards platforms that can demonstrate strong cross-domain trust, not merely strong internal controls. Second, interoperability standards are a catalyst for network effects. The combination of DIDs and VCs, when implemented with interoperable protocols (for example, DIDComm-based messaging and standardized VC schemas), enables agents to move fluidly across clouds, platforms, and partner networks. This reduces integration costs and creates a multi-vendor ecosystem in which agents can be issued and revoked credentials by disparate trust anchors. Third, privacy-preserving identity is indispensable for regulatory and consumer considerations. Enterprises will gravitate toward solutions that support selective disclosure, jurisdiction-aware data minimization, and cryptographic proofs that validate compliance without revealing sensitive personal data. ZKPs and related technologies are not peripheral; they are becoming design constraints that shape product roadmaps and partner criteria. Fourth, governance and attestation matter. The ability to attest an agent’s behavior, its compliance posture, and its access history provides the auditability that regulators require and risk managers rely upon. A credible agent-identity layer needs a transparent, tamper-evident ledger or registry of attestations, revocation events, and policy changes, anchored to trusted authorities and easily auditable by external stakeholders. Fifth, the value chain is shifting toward platform-enabled ecosystems. Identity wallets, trust registries, attestation authorities, revocation services, and governance frameworks will co-create value as a platform rather than as isolated components. The most durable businesses will be those that orchestrate these components into scalable, compliant, and developer-friendly offerings capable of rapid integration across AI stacks and enterprise data landscapes.
Investment Outlook
The investment opportunity in infrastructure for agent identity spans early-stage innovation, platform plays, and strategic acquisitions. Early-stage bets are most attractive in three sub-segments: (1) verifiable credentials ecosystems and credential issuance/verification tooling tailored for AI agents and enterprise data domains; (2) decentralized identity wallets and bridge layers that facilitate cross-platform portability of identities and attestations; and (3) policy engines and governance dashboards that enable real-time access control, attestation management, and regulatory reporting for autonomous agents. Platform plays include middleware that harmonizes identity data across cloud providers, data lakes, and AI platforms, delivering standardized APIs, revocation registries, and privacy-preserving verification services. Strategic opportunities exist for incumbents in cloud IAM and enterprise software to acquire or partner with niche players to accelerate the integration of agent identity with existing SSO, IAM, and data governance programs. In terms of market sizing, a conservative baseline view suggests a multi-billion-dollar TAM by the end of the decade, expanding at a high-teens to mid-twenties compound annual growth rate driven by proliferating AI agents, cross-border data exchanges, and regulatory convergence toward verifiable trust verification across ecosystems. A more bullish scenario envisions a multi-tens-of-billions TAM if standardized identity fabrics become a universal enabler of trusted agent-to-agent and agent-to-human interactions across public and private sectors. Both scenarios share common drivers: the imperative to reduce risk and non-compliance costs, the demand for portable credentials that survive platform migrations, and the need for auditable traceability in AI-enabled operations.
The competitive landscape is likely to crystallize around three archetypes. The first is a set of specialist identity technology providers—DID and VC issuers, cryptographic proof engines, and revocation registries—lying at the core of the identity stack. The second is the platform layer—cloud providers and AI infrastructure firms—that will commoditize certain identity primitives while layering governance and interoperability capabilities on top. The third is governance-enabled ecosystems—industry consortia, regulatory bodies, and enterprise alliance networks—that create trusted marketplaces for agent identities and attestations. Investors should seek structural bets that emphasize interoperability and governance as defense against vendor lock-in, as well as product-led growth signals such as broad developer adoption, open standard support, and measurable reductions in onboarding time for AI-driven workflows. From a capital-allocation perspective, the most attractive bets will blend deep technical capability with practical industry use cases, a clear path to revenue (including enterprise licensing or usage-based models for attestations), and a credible roadmap to achieve regulatory-compliant, scalable deployments across multiple verticals.
Future Scenarios
In the baseline scenario, the market progresses along gradual standardization and incremental improvements in agent identity tooling. Firms adopt interoperable identity modes for critical AI-based operations, but fragmentation persists as various cloud providers and enterprise software vendors maintain proprietary extensions. The net effect is a steady, predictable uplift in identity-related spend, with moderate consolidation among identity-native startups and ongoing partnerships into broader IAM suites. A second, more transformative scenario envisions rapid standardization—DID, VC, and DIDComm become universally adopted, with interoperable trust registries and attestation authorities anchored by industry groups and regulators. In this world, cross-organizational AI agents can securely operate across ecosystems with minimal bespoke integration, enabling accelerated AI adoption, new business models (such as cross-domain agent marketplaces), and a measurable decline in compliance friction. A third scenario features platform-driven lock-in, where dominant hyperscalers implement deeply integrated agent-identity fabrics across their cloud and AI offerings. This could accelerate enterprise deployment but raises concerns about interoperability, data sovereignty, and competitive dynamics, potentially inviting regulatory scrutiny and prompting open-standards pushback. A fourth scenario centers regulatory mandates—governments or supranational bodies require standardized agent identities for critical sectors (finance, healthcare, public services). In this environment, the agent-identity infrastructure becomes a compliance backbone, with procurement and vendor evaluation centered on adherence to traceable identity, auditable behavior, and enforceable revocation capabilities. Across these scenarios, the resilience of identity infrastructure will hinge on privacy-preserving capabilities, robust attestation ecosystems, and governance that can withstand both cyber threats and regulatory scrutiny.
Conclusion
Infrastructure for Agent Identity is positioned to become a strategic enabler of scalable, trusted, AI-first ecosystems. The convergence of standards-based identity primitives, privacy-preserving verification, and governance-driven attestations creates a compelling investment thesis for those who can integrate technical rigor with practical enterprise requirements. The pathway to material value lies in identifying players that can deliver interoperable identity fabrics, bridge cross-domain data and AI platforms, and provide auditable trust across complex operational contexts. While the horizon features regulatory-led growth and potential platform consolidation, the demand signal from enterprises seeking safer, faster, and more compliant AI deployment suggests a durable, multi-year growth cycle. Investors should incorporate a disciplined assessment of interoperability capabilities, governance and attestation mechanisms, and data minimization strategies when evaluating opportunities in this space, recognizing that the most durable franchises will be those that not only build robust cryptographic identity rails but also partner effectively with regulators, standard bodies, and enterprise clients to realize scalable, trust-enabled AI operations.
