Agentic AI was the defining story of 2025. But the industry vocabulary has already mutated — analysts, labs, and CEOs are now describing what comes after the agent. Five candidates dominate the 2026 conversation, each with a champion and a concrete milestone. Here’s the map, with the hype check at the end.

1. Multiagent systems — the analyst-language successor

Gartner explicitly names multiagent systems as agentic AI’s evolution in its Top Strategic Technology Trends for 2026 — “collections of AI agents that interact to achieve individual or shared complex goals” (Gartner, Oct 2025). The plumbing is already here: Anthropic’s open Model Context Protocol (MCP), launched November 2024, became the de-facto standard for agent–tool interoperability, with server downloads growing from 100,000 to over 8 million per month within six months (MCP Blog, Nov 2025). In December 2025 Anthropic donated MCP to a new Linux Foundation Agentic AI Foundation, co-founded with Block and OpenAI.

2. World models — the lab-language successor

Where an LLM predicts the next word, a world model predicts the next state of an environment. Google DeepMind’s Genie 3 (Aug 2025) was billed as the “first real-time interactive general-purpose world model,” generating playable 720p environments from a text prompt (DeepMind). NVIDIA launched its Cosmos world-foundation-model platform at CES 2025; OpenAI shipped Sora 2 in September 2025; and Yann LeCun left Meta in late 2025 to pursue his JEPA world-model architecture full-time — a clear signal that the field’s most senior researchers see this, not bigger LLMs, as the road to more general intelligence.

3. Embodied AI — where the capital is flowing

Embodied AI — AI with a physical body — saw the biggest funding rounds of the “after the agent” wave. Figure AI raised more than $1 billion at a $39 billion valuation (Sept 2025) and unveiled its Helix vision-language-action model (Figure). Physical Intelligence open-sourced its π0 generalist robot policy and raised $600M at $5.6B (Nov 2025). 1X opened pre-orders for its $20,000 Neo home humanoid. CEO timelines increasingly put useful real-world robots around 2027.

4. Self-improving research agents

AI that does science is no longer hypothetical. Sakana AI’s AI Scientist-v2 produced the first fully AI-generated paper to pass workshop-level peer review (ICLR 2025) (arXiv). DeepMind’s Gemini Deep Think achieved official gold-medal standard at the 2025 International Mathematical Olympiad, and its AlphaEvolve coding agent discovered a faster matrix-multiplication algorithm and improved Google’s own data-center scheduling (DeepMind, May 2025).

5. The AGI timelines converge on 2026–2030

The lab leaders have largely aligned. Sam Altman’s June 2025 essay The Gentle Singularity sketches agents doing real cognitive work in 2025, novel-insight systems in 2026, and real-world robots by 2027 (blog.samaltman.com). Dario Amodei’s Machines of Loving Grace says “powerful AI” could arrive “as early as 2026” (darioamodei.com). Demis Hassabis puts ~50% odds on AGI within 5–10 years. Mark Zuckerberg’s July 2025 Personal Superintelligence memo reframes Meta’s mission entirely around superintelligence.

The hype check: agent washing

Before declaring the agent dead, weigh the counter-evidence. Gartner forecasts that over 40% of agentic AI projects will be canceled by the end of 2027 due to unclear ROI and weak governance, and estimates that of the thousands of vendors claiming “agentic” capability, only about 130 are genuine — the rest engaged in “agent washing” (Gartner, Jun 2025). An MIT NANDA study found roughly 95% of enterprise generative-AI pilots delivered no measurable P&L impact. The next paradigm is arriving — but so is a reckoning for the projects that slapped “agent” on a chatbot.

The bottom line

  • In analyst language, the successor is multiagent systems.
  • In lab language, it’s world models and embodied AI.
  • In CEO language, it’s superintelligence on a 2026–2030 clock.
  • In the enterprise, most “agents” are still chatbots — and a 40% cancellation wave is coming first.
