State of Data Compliance 2026
The global data brokerage market is undergoing its most significant structural shift in a decade. Regulatory pressure, cookie deprecation, and the EU AI Act's provenance requirements are forcing every enterprise data buyer to re-evaluate their supply chain. This briefing synthesizes the key trends, market data, and regulatory developments shaping consent-compliant data in 2026.
1. The Consent-Compliant Data Market: 2026 Size & Growth
The global data broker market is valued at approximately $280 billion as of 2024 and is projected to reach $490 billion by 2029 (CAGR: 11.8%). Within this broader market, the consent-compliant data segment is outpacing by a significant margin.
| Segment | 2024 Est. | 2029 Proj. | CAGR |
|---|---|---|---|
| Global data broker market | $280B | $490B | 11.8% |
| Consent/privacy-compliant data | $14B | $68B | 37% CAGR |
| B2B data intelligence | $45B | $89B | 14.6% |
| Identity resolution & enrichment | $22B | $51B | 18.3% |
Key insight: The consent-compliant data segment is growing at 3× the market average, driven entirely by regulatory pressure forcing enterprise buyers off non-consented data sources. This is not a niche — it is the market's fastest-growing structural shift.
2. The Global Privacy Regulation Wave
The regulatory environment that data buyers operate in has fundamentally changed since 2022. What began as GDPR enforcement in the EU has cascaded into a global framework of comprehensive privacy law — covering jurisdictions responsible for the majority of the world's enterprise data purchasing activity.
U.S. State Privacy Laws: From 5 to 19
As of Q1 2026, 19 U.S. stateshave enacted comprehensive privacy laws — up from just 5 in 2022. The wave includes CCPA/CPRA (California), Virginia CDPA, Colorado CPA, Texas TDPSA, and a growing roster of state-level frameworks modeled on GDPR's consent requirements. Together, these laws cover over 60% of the U.S. population.
EU AI Act: Layering on Top of GDPR
EU AI Act enforcement began in 2025 and is adding data provenance requirements directly on top of GDPR obligations. For EU-facing companies, this means tracking complete consent chains not just for customer data — but for the training data used in any high-risk AI system deployed in the EU market.
India's DPDPA: A $4B+ Compliant Market Opens
India's Digital Personal Data Protection Act went into effect in 2025, establishing explicit consent requirements for personal data processing and opening a $4B+ compliant data market. Indian enterprises purchasing or processing personal data for marketing, analytics, and AI must now document consent provenance.
Brazil's LGPD: Enforcement Maturity
Brazil's Lei Geral de Proteção de Dados saw enforcement maturity in 2024–2025, with the ANPD (national data authority) issuing its first significant fines. Brazilian enterprises and international companies serving Brazilian users now face real enforcement risk on non-compliant data purchasing and processing.
3. EU AI Act Article 10: Training Data Consent Requirements
Of all the 2026 regulatory developments, EU AI Act Article 10 carries the most immediate practical consequence for enterprise data teams building or procuring AI systems. Article 10 imposes explicit data governance requirements on training datasets used in high-risk AI systems — and consent documentation is central to those requirements.
Article 10 in Plain Language
High-risk AI systems must be trained on data that satisfies quality criteria including: documentation of the data collection process, the purpose for which data was collected, known biases, and — critically — evidence that personal data was collected with appropriate legal basis, including consent where required under GDPR. This requirement applies to the AI system provider, not just the data broker supplying the training data.
The practical consequence: an enterprise deploying a customer-facing AI model trained on third-party behavioral data must be able to produce consent documentation for that training data. This requirement is currently impossible to fulfill using the majority of legacy data broker products — which were built on opt-out, implied consent, or "legitimate interest" frameworks.
Non-Compliant Pattern
Third-party data purchased from a legacy broker with "opt-out" or "legitimate interest" consent basis, used to train a customer credit-scoring model deployed in the EU.
Compliant Pattern
Third-party data with documented explicit opt-in consent, consent timestamps, and scope documentation — with a full consent attestation report on file for regulators.
4. The Cookie Deprecation Demand Gap
Google Chrome completed third-party cookie deprecation in 2024, eliminating the data infrastructure underpinning the majority of programmatic advertising targeting. The downstream impact on data purchasing is structural and permanent.
$10B+
Estimated annual demand gap for consented, persistent identity data — created directly by Chrome's third-party cookie deprecation. AdTech companies, DSPs, and DMPs are scrambling to replace cookie-based targeting with first-party and consented second-party data at scale.
The gap is not just technical — it is compliance-structural. Cookie-based data pipelines operated in a legal grey zone that regulators tolerated as long as browser-level consent signaling existed. With cookies gone, replacement identity signals must carry explicit opt-in consent documentation to be usable by enterprise buyers whose legal teams now require it before signing data purchase agreements.
Consent Management Platforms (CMPs) — including OneTrust, TrustArc, and Usercentrics — have standardized consent collection at scale, creating a growing supply of properly-consented consumer data. The missing piece is a compliant distribution layer that can connect CMP-sourced consent signals to enterprise data buyers.
5. Why Legacy Data Brokers Cannot Deliver GDPR/CCPA Compliance
The five major incumbents — Acxiom, Nielsen, Experian, Oracle Data Cloud, and TransUnion — were built on architectures that predate modern consent requirements. Each faces structural limitations that cannot be resolved without a ground-up rebuild of their data collection and consent management infrastructure.
| Provider | Consent Model | Core Compliance Gap |
|---|---|---|
| Acxiom | Opt-out / implied | Majority of data collected under 'legitimate interest' — increasingly non-compliant in GDPR/CCPA strict-read contexts. Named in multiple GDPR complaints in the EU. |
| Nielsen | Panel-based | EU panel data collection under DPA investigation in Germany and France. Minimal CCPA operational controls at scale. |
| Experian | Aggregated (multi-source) | Consent opacity: aggregates from hundreds of sources with inconsistent provenance. Enterprise legal teams increasingly blocking purchases pending compliance review. |
| Oracle Data Cloud | Cookie-based (pre-GDPR) | EU data effectively unusable for GDPR-compliant buyers. Core audience product functionally broken post-Chrome deprecation. |
| TransUnion | Mixed / fragmented | Neustar acquisition data has heterogeneous consent models — no unified consent attestation possible across the product suite. |
Enterprise procurement teams at Fortune 500 companies increasingly require SOC 2 Type II, ISO 27001, and explicit consent attestation before purchasing data. The legacy broker market cannot meet this requirement as currently architected.
6. Summary: Privacy Laws by Jurisdiction (2026)
The following table summarizes the major active privacy regulations affecting enterprise data purchasing as of 2026, organized by jurisdiction.

| 19 US States | Various CPAs | Consent or opt-out requirements varying by state; all modeled on GDPR/CCPA frameworks | Active as of Q1 2026 |
7. Conclusion: What This Means for Enterprise Data Buyers
The convergence of expanding privacy regulation, cookie deprecation, and EU AI Act enforcement has created a compliance inflection point that enterprise data buyers cannot defer. The key takeaways for 2026:
- The consent-compliant data market is growing at 37% CAGR — 3× the broader market — because regulatory pressure is converting non-compliant data purchasing into a legal liability, not just a preference.
- EU AI Act Article 10 has introduced training data provenance requirements that directly affect any enterprise building or procuring AI systems for deployment in the EU market.
- 19 U.S. states now have comprehensive privacy laws covering over 60% of the U.S. population — legacy 'consent-optional' data purchasing is now a legal risk, not a best practice gap.
- The $10B+ annual demand gap left by cookie deprecation will only be filled by consented, first-party or properly documented second-party data.
- Legacy data brokers — built on opt-out, implied consent, or cookie-based architectures — cannot structurally deliver the consent documentation that enterprise legal and compliance teams now require.
For data buyers operating under GDPR, CCPA, or any of the 2026-active privacy frameworks, the question is no longer whether to prioritize consent-compliant data sourcing — it is how quickly the transition can be completed before a regulatory event forces it.
