> Anthropic overtakes OpenAI in US business adoption, Uber burns its 2026 AI budget by April, and autonomous agents expand attack surfaces by 450%.

## Key points

- Anthropic has surpassed OpenAI in US business adoption for the first time, driven by enterprise demand for reliability in production environments.
- Uber exhausted its full 2026 AI budget by April, illustrating how token-based consumption pricing can outpace finance teams' visibility and controls.
- Each autonomous AI agent added to a corporate network increases the attack surface by more than 450% relative to a human user, according to Cisco analysis cited by Forbes.

Enterprise AI in mid-2026 is being pulled in three distinct directions simultaneously: a reshuffling of model allegiances at the top of the market, a cost crisis outpacing finance teams' ability to respond, and a security exposure that compounds with every autonomous agent deployed. Taken together, these trends signal that the relatively forgiving phase of AI experimentation has ended, and the harder work of institutional governance has begun.

## Anthropic pulls ahead in the enterprise market

For the first time, Anthropic has surpassed OpenAI in US business adoption, according to Forbes contributor Sandy Carter, as reported by MarketScale. The shift reflects what enterprise buyers say they value most right now: reliability and consistent performance when running AI in production environments, not just in controlled pilots or demos.

Claude's ascent marks a broader move away from selecting AI models based on consumer brand recognition toward evaluating them against the demands of mission-critical workflows. Organizations deploying agents at scale need models that behave predictably under load, a criterion that appears to be tilting purchasing decisions toward Anthropic's offering, per Carter's analysis.

The development applies direct pressure on OpenAI, which has invested heavily in its enterprise go-to-market motion. Whether it can recover ground in the business segment will likely depend on how quickly it addresses the reliability concerns that Carter's reporting suggests are redirecting buyers toward Claude.

## Token billing is blowing apart AI budgets

Even as organizations rush to adopt AI, many are discovering that consumption-based pricing creates a dangerous gap in financial visibility. Forbes contributor John Sviokla, cited in MarketScale's coverage, describes the dynamic as a "token trap", a situation where costs tied to the number of tokens processed can spiral far beyond what finance teams projected.

The sharpest data point in Sviokla's reporting: Uber burned through its entire 2026 AI budget by April. That single figure encapsulates a crisis in which organizations struggle to connect AI spending to measurable returns before the money runs out. The problem is set to intensify as agentic systems, which autonomously trigger additional model calls, become standard infrastructure.

Sviokla outlines three practical responses: establish token consumption monitoring equivalent to cloud cost dashboards, build unit-economics frameworks that tie token spend to specific business outcomes, and create governance structures requiring ROI justification before new AI workloads are approved. Glean's 2026 cost analysis reinforces the point, noting that advanced enterprise AI deployments, those incorporating vector embeddings, deep-learning ranking, real-time personalization, and agentic capabilities, routinely exceed $500,000, with some large-scale implementations reaching into the millions.

Glean's analysis notes that a basic AI search deployment starts around $15,000 to $40,000, mid-tier systems land between $40,000 and $120,000, and advanced enterprise deployments routinely exceed $500,000. Critically, Glean cautions that these upfront figures represent only a fraction of long-term investment, as costs evolve with user adoption, new data sources, and the shift from retrieval to workflow automation.

## Autonomous agents are multiplying the security attack surface

The proliferation of AI agents is introducing a security challenge that many organizations have not fully priced into their risk models. According to Cisco's analysis cited by Forbes, as reported by MarketScale, each autonomous AI agent added to a corporate network increases the attack surface by more than 450% relative to a human user performing equivalent tasks.

Recorded Future's research into emerging enterprise AI security risks corroborates the scale of that exposure. Agents require broad, cross-environment permissions to operate; compromised credentials, SSO platforms, or agent identities could enable large-scale service disruption or data exfiltration, according to Recorded Future's analysis. The firm also highlights that many AI tools currently operate in a trust-by-default mode, creating significant vulnerabilities that expand further when extended to autonomous agents capable of sending emails, deleting files, or authorizing payments.

Prompt engineering presents an additional vector: threat actors can manipulate agents into carrying out malicious actions through carefully crafted inputs, reinforcing the need for layered security controls and human-in-the-loop checkpoints, per Recorded Future. Gartner predicts that as many as 40% of enterprise applications will incorporate task-specific AI agents by the end of 2026, up from less than 5% in 2025, a trajectory that makes resolving these vulnerabilities urgent.

## Governance is the gap that separates leaders from laggards

Cutting across all three fault lines is a governance deficit that Iternal AI's enterprise AI strategy framework quantifies starkly: 97% of executives believe generative AI will fundamentally transform their companies, while only 4% are generating substantial value from it. Iternal AI attributes that gap almost entirely to underinvestment in people and processes, the "70%" in what the framework calls the 10-20-70 rule, which holds that only 10% of AI success depends on algorithms, 20% on infrastructure, and 70% on workforce capability and process design.

Iternal AI's framework, authored by John Byron Hanby IV in The AI Strategy Blueprint, argues that the organizations capturing transformational value are not technologically superior, they have built institutional capability for deploying AI effectively and started with people, not models. That framing aligns with the agentic AI challenge described in Recorded Future's research: an AI agent that can independently book travel, file reports, or execute financial transactions needs oversight structures analogous to those applied to human workers, including performance review, access limits, and clear accountability when something goes wrong.

Deloitte anticipates that at least 75% of companies will use agentic AI to some extent by 2028, according to Recorded Future's citation of Deloitte's 2026 State of AI report. For enterprise AI programs entering the second half of 2026, the defining test is whether internal governance capabilities, financial, security, and organizational, can keep pace with the speed at which vendors are deploying new capabilities.
