Analysis: Anthropic's 5.7% Foothold Signals Agent Control Plane War in 2026

The Agent Control Plane: The New Strategic Battleground

For two years, the enterprise AI narrative was dominated by a model war: GPT-4 versus Claude versus Gemini. That framing is now obsolete. The next decisive fight is over the agent control plane—the infrastructure layer where agents plan, call tools, access data, run workflows, and prove compliance. New VB Pulse data reveals that Anthropic has registered its first measurable foothold in this layer, moving from 0% to 5.7% in February 2026. While small, this marks a structural shift: the battle for enterprise AI is no longer about intelligence alone—it's about operational control.

Why the Control Plane Matters More Than the Model

A model is relatively easy to swap. An agent runtime is not. Once workflows, permissions, audit logs, and execution monitoring live inside a provider's environment, switching costs become infrastructure-level. This is why Microsoft leads with 38.6% adoption: its Copilot Studio and Azure AI Studio sit inside an existing enterprise stack. But Anthropic's emergence—even at 5.7%—signals that buyers are starting to value governance and security over convenience. Security and permissions ranked as the top selection criterion at 37.1%, while vendor lock-in concern rose to 25.7%. Enterprises want managed infrastructure, but they fear dependency.

Anthropic's Strategic Bet: Open Protocol, Sticky Runtime

Anthropic's Model Context Protocol (MCP) is open, reducing integration friction. But its managed agent harness—with sandboxing, built-in tools, and API-run sessions—creates lock-in at the runtime layer. This dual approach allows Anthropic to attract enterprises seeking flexibility while building switching costs. The VB Pulse Foundation Models tracker shows Claude's enterprise preference surging from 23.9% in January to 56.2% in March (directional). That model momentum is spilling into orchestration. If Anthropic can persuade Claude customers to adopt its managed runtime, it becomes part of enterprise infrastructure—not just a model in a multi-model portfolio.

Winners and Losers in the New Landscape

Winners: Microsoft retains its default position, with no competitor within 13 percentage points. Anthropic gains a strategic foothold and differentiation through MCP and managed agents. Hybrid control plane architectures (35-36% expected) favor vendors that support multi-model flexibility.

Losers: OpenAI's second-place share (25.7%) is stagnant, and its closed ecosystem may struggle against Anthropic's open protocol. LangChain and LangGraph collapsed from 5.4% to 1.4%, as enterprises abandon standalone frameworks for integrated platforms. External orchestration providers fell from 8.9% to 2.9%, confirming that enterprise buyers prefer provider-managed or hybrid solutions.

Second-Order Effects: The Rise of Agent Ops and Cross-Vendor Collaboration

The shift from LLMOps to Agent Ops means governance must cover the entire agent lifecycle, not just model calls. As Rania Khalaf of WSO2 notes, guardrails on LLM calls won't catch an agent thrashing in an unbreakable loop. This creates demand for identity and data management layers that sit above orchestration. Ev Kontsevoy of Teleport argues that orchestration without identity multiplies chaos. Meanwhile, Arick Goomanovsky of BAND sees the next cycle as cross-vendor agent collaboration—a layer that lets agents from Microsoft, OpenAI, and Anthropic operate as one workforce. This suggests that no single provider will win the entire stack; the winning architecture will be an interoperable control plane.

Market Impact: Consolidation and the Hybrid Imperative

The market is consolidating around a few integrated platforms, while open-source orchestration layers are being marginalized. However, the hybrid control plane remains the leading expected architecture (35-36%). Enterprises are not willing to give full control to any single provider. This creates an opportunity for vendors like Collibra (AI Command Center) and WSO2 that offer independent governance layers. For Microsoft, the challenge is to maintain distribution advantage while addressing lock-in fears. For Anthropic, the path is to become the agent runtime for high-stakes workloads where safety and governance are paramount.

Executive Action: What to Do Now

• Audit your agent runtime dependencies: Assess how much of your agent infrastructure is tied to a single provider. Plan for portability by adopting open protocols like MCP and separating policy from agent logic.
• Prioritize governance over model quality: With security and permissions as the top selection criterion, invest in identity, audit, and data management layers before scaling agent deployments.
• Prepare for multi-vendor orchestration: No single provider will dominate. Build a hybrid control plane that can route across models and runtimes, ensuring flexibility and avoiding lock-in.
