Inference Economics Takes Over Neocloud War in $643M Eigen Deal

Nebius's $643M purchase of 20-person Eigen AI, valuing inference optimization at $32 million per engineer, and CoreWeave's $21 billion Meta deal signal that the neocloud race now centers on extracting maximum tokens per GPU rather than GPU count.

Inference Is the Neocloud Battleground as Nebius Pays $643M

As CoreWeave locked $21 billion in Meta and Anthropic deals in 48 hours and xAI may become a neocloud in orbit, the per-token economy is reshaping who builds, who pays, and who captures the margin in AI infrastructure.

AI Inference's New Energy Floor: $0.0037 per 1M Tokens

As hyperscale AI capex tops $200B in 2026 and cooling infrastructure grows at 19.2% annually, the true per-token energy cost reveals a hidden margin shift that few invoices disclose.

Spot vs Reserved GPU Pricing: $1.12/hr to $8.42/hr in 2026

The GPU market's 2026 split pits $1.12/hr spot instances against $2.35/hr reserved H100 contracts, with enterprises hoarding idle capacity that drives both prices upward.

H100 Reserved Capacity Hits $2.35/Hour Floor in 2026

Reserved-contract GPU pricing has surged 38% in six months while spot availability tightens and enterprise fleets idle at 5% utilization—the per-token math is shifting faster than procurement cycles can track.
