Grok roadmap: Grok 4.6 is expected to drop ~next week (post date 2026-08-04)…

Brief

SpaceXAI announced an aggressive model and infrastructure roadmap: Grok 4.6 imminently, 4.7 in weeks, and Grok 5 by year-end trained on 25 years of SpaceX data. They plan >2 GW online by end-2026 (targeting nearer 10 GW in 2027) on NVIDIA Vera Rubin hardware, expect Cursor to close soon, StarMind NVL72 satellites launching next year, and project $100B ARR aided by $6.7B Q3 cloud contracts and <1-year capex payback.

Why it matters

Grok roadmap: Grok 4.6 is expected to drop ~next week (post date 2026-08-04), Grok 4.7 in 3–4 weeks, and Grok 5 planned before the end of 2026; SpaceX will incorporate its entire 25-year data corpus into Grok training to make it “by far the BEST ENGINEER.”

Key details

  • Colossus compute & NVIDIA: SpaceX claims 2+ GW of compute online by end of 2026, with capacity by end of 2027 targeted 'several times higher' (company says closer to 10 GW than 5 GW); they will build exclusively on NVIDIA’s Vera Rubin architecture (NVL72).
  • Commercials & products: Cursor acquisition should close soon (regulatory hurdles nearly cleared); StarMind AI1 satellites will use an optimized NVL72 and start launching next year; CFO cites <1-year payback on new compute capex, Q3 already contracted $6.7B in cloud revenue, and a trajectory to $100B ARR by year-end.

🚨 SPACEXAI UPDATES FROM Q2 EARNINGS

GROK:
>Grok 4.5 was a huge improvement
>Grok 4.6 dropping ~next week
>Grok 4.7 in three or four weeks
>Grok 5 before end of the year

“We will be incorporating the ENTIRE CORPUS of SpaceX data… ALL the data SpaceX has ever produced over the course of a quarter century into Grok training… This will make Grok by far the BEST ENGINEER”

COLOSSUS COMPUTE:
>building data centers faster than anyone else
>efficiency of compute deployment also the highest
>2GW+ online by end of 2026
>by the end of next year… SEVERAL times higher
>closer to 10GW than 5GW

NVIDIA x SPACEX:
>we’ve decided to build EXCLUSIVELY on NVIDIA
>Vera Rubin architecture is the best architecture
>“we greatly value a close cooperation and partnership on many levels with NVIDIA”

CURSOR:
>acquisition should close quite soon
>through almost all of the regulatory hurdles

STARMIND AI1 SATELLITES:
>optimized Vera Rubin NVL72 in orbit
>"we expect to start launching these next year"
>a radical simplification of the normal NVL72 rack
>will cost less, and be more effective
>so deploying them on the ground AND in space

SPACEX CFO:
>robust demand for cloud services
>increasingly favorable economics with each agreement we sign
>supply-demand imbalance in the compute market will continue
>less than ONE YEAR payback on new compute capex
>Q3 already contracted $6.7B more cloud revenue
>ramping starting in October

“We believe this puts us on a trajectory, including contribution from Cursor, to reach 100 BILLION of ARR by the end of this year.”
