## Summary

[Xai](/ko/entity/xai) closed an upsized Series E in January 2026, raising $20bn against a $15bn target at a reported ~$230bn valuation. Backers include Valor, Stepstone, Fidelity, the Qatar Investment Authority, MGX and Baron, with [Nvidia](/ko/entity/nvidia) and Cisco as strategic investors funding the Colossus GPU clusters. The capital underwrites what xAI calls the largest GPU clusters in the world for Grok. In a notable twist, xAI then agreed to lease the entire output of its Colossus 1 data centre to rival [Anthropic](/ko/n/anthropic-compute-10gw-2026) at ~$1.25bn/month through May 2029, monetising spare capacity even as it races on model quality. The raise keeps xAI in the [capital arms race](/ko/n/openai-122bn-softbank-round-2026) with OpenAI and Anthropic.

## By the numbers

- $20bn, Series E (upsized from $15bn target).
- ~$230bn, reported valuation.
- Jan 2026, round close.
- ~$1.25bn/month, Colossus 1 lease to Anthropic through May 2029.
- Nvidia, Cisco, strategic investors.

## Why it matters

xAI's valuation rests on raw compute scale and Musk's distribution via X and Tesla. Leasing Colossus capacity to Anthropic shows even rivals are interdependent through hardware, and that GPU clusters are an asset class in their own right, rented when not training.

## What to watch

- Grok model releases against GPT-5.5, Gemini 3.5 and Opus 4.8.
- xAI/SpaceX financial entanglement ahead of SpaceX's listing.
- Whether xAI raises again in 2026 to keep pace on compute.
