Record-Breaking AI Seed Rounds Top $1 Billion: Largest Deals Reshaping Early-Stage VC in 2026

The venture capital world is witnessing a seismic shift as AI startups dominate the largest seed rounds of the past six months, pouring billions into early-stage innovation.

Paris-based Advanced Machine Intelligence leads with a massive $1.03 billion seed round, the biggest ever in Europe for AI models predicting real-world sensor data.

Spotlight on Mega AI Seed Deals

Unconventional AI in San Francisco secured $475 million to develop energy-efficient silicon circuits mimicking biological neurons.

Silicon Valley's Humans& raised $480 million in January, achieving a $4.48 billion valuation for its human-centric foundational AI models.

Periodic Labs attracted $300 million to revolutionize science and experimentation through AI in materials design and engineering.

Merge Labs, co-founded by Sam Altman and led by OpenAI, raised $252 million for advancing brain-computer interfaces.

China-based players like Lingchu Intelligence and Humanoid Robot Innovation Center each crossed the $100 million mark for robotic AI platforms and humanoid tech.

Trends, Impact, and Future Outlook

At least 12 such $100 million-plus seed rounds have occurred globally, totaling billions and highlighting AI's physical world applications.

Historically, large seed rounds over $10 million were just 2% of deals in 2018, now comprising 9%, with 27 mega-deals over $100 million since early 2025.

This influx empowers startups to pursue ambitious goals in robotics, energy, and brain interfaces without traditional bootstrapping constraints.

While the impact accelerates AI-physical integration, the long-term viability of these moonshot bets remains unproven.

Looking ahead, this trend signals a new era of seed funding, prioritizing scale and competition in the AI race.
