Summary

Written by a model from the transcript; not yet reviewed.

Brad Gerstner hosts Gavin Baker and Andrew Fox from Atreides, plus Clark Tang from Altimeter, to break down the SpaceX IPO at a $1.77 trillion valuation. The conversation covers three main business lines: the launch and Starlink connectivity business, the terrestrial AI compute business built on deals with Anthropic and Google, and the XAI/Cursor model business. Gavin argues that XAI's deal with Google generates more operating profit per gigawatt than any other player, and that speed is literally cost—Elon brought data centers online in 122 days. Fox lays out the orbital compute math: roughly $5 billion per gigawatt in space versus $25 billion terrestrially, a 5x reduction on half the bill of materials.

The second half shifts to the AI model race. Gavin highlights that Composer 2.5 was Pareto dominant for coding just 12 days before the episode, and that Grok 4.3 (a 1.5 trillion parameter model) is currently training with Cursor data injected into pre-training. He argues that long-running agents represent a new class of capability, using an Einstein analogy: imagine Einstein thinking 24 hours a day for a year without distraction. The group debates whether open-source models will erode frontier revenue, concluding that frontier models likely capture 90% of economic value while open source captures 80% of tokens consumed. Brad notes Morgan Stanley raised its 2027 AI CapEx forecast to $1.1 trillion, and the group believes the actual number will be closer to $1.5 trillion.

  • XAI's deal with Google generates more operating profit per gigawatt than Anthropic, Meta, Google, or OpenAI, with a 55% ARR on Claude making the financing math compelling. 3:00
  • Orbital compute costs roughly $5 billion per gigawatt versus $25 billion terrestrially, a 5x reduction on half the data center bill of materials. 26:52
  • Frontier models capture approximately 90% of AI economic value while open source may capture 80% of tokens, and open source success is actually bullish for compute providers. 53:32
  • Less than 0.2% of people on earth are using AI in an agentic way, meaning the demand side far outstrips supply for the foreseeable future. 1:07:55
  • Morgan Stanley raised its 2027 AI CapEx forecast from $950 billion to $1.1 trillion, and the group believes the actual number will be closer to $1.5 trillion. 1:03:48

Highlights

  • 3:00

    XAI Outperforms on Per-Gigawatt Economicsinsight

    Gavin Baker points out that XAI's deal with Google generates more operating profit per gigawatt than Anthropic, Meta, Google, or OpenAI. He notes a 55% ARR on Claude and argues that borrowing at 6-8% to invest in 55% ARR is compelling.

  • 7:08

    Rapid Reusability as the Key Leverstrategy

    Andrew Fox argues that rapid reusability of Starship is the foundational variable for all SpaceX businesses. He describes the goal as getting rockets to fly at airline cadence, with both stages reusable 30-50 times before retrofit.

    100,000 GPUs in 19 Daysdata

    A clip from a previous podcast with Jensen Huang notes that 100,000 GPUs in one cluster is the fastest supercomputer on the planet. Normally such a system takes three years to plan and one year to deploy; SpaceX did it in 19 days.

  • 26:52

    Orbital Compute Cost Advantagedata

    Andrew Fox calculates that putting a gigawatt of compute into space costs about $5 billion, versus $25 billion for the land, shell, power, and cooling portion of a terrestrial data center. That is a 5x reduction on half the bill of materials.

    Einstein Thinking 24 Hours a Dayinsight

    Gavin Baker argues we do not know how smart frontier models actually are because nobody has run them continuously for a year. He uses an Einstein analogy: imagine Einstein thinking about physics 24 hours a day for a year without eating, sleeping, or getting distracted.

  • 53:55

    Open Source Bullish for Computeinsight

    Gavin argues that open source success is actually bullish for compute and hardware providers. If frontier models capture less margin, more spending flows to compute. The better open source does, the better it is for compute providers.

  • 1:07:55

    0.2% Agentic Usage Ratedata

    Andrew Fox notes that less than 0.2% of people on earth are using AI in an agentic way. He points out he personally consumes 500 CPU cores and 5 GPUs 24/7, and if that scales to any meaningful percentage of the population, the shortage environment persists.

  • 1:18:14

    Revenue Acceleration vs. Mag7 Historydata

    Brad Gerstner notes that the Mag7 added 1 trillion in revenue over the last seven years, and the forecast is that SpaceX, Anthropic, and OpenAI will add another trillion in just four to five years—three companies in half the time.

About this episode

Brad Gerstner sits down with Gavin Baker and Andrew Fox of Atreides Management, alongside Altimeter partner Clark Tang, to break down one of the biggest questions in tech and markets: how should investors think about the SpaceX IPO? They unpack the major levers behind SpaceX’s next phase: Starship rapid reusability, Starlink broadband and direct-to-cell, Elon’s emerging AI compute business, xAI’s model ambitions, the Cursor acquisition, and the long-term promise of orbital data centers. The group also debates whether SpaceX is becoming a new kind of AI hyperscaler — “Elon Web Services” — and what that means for the future of compute, cloud, and frontier intelligence. Then they dive into the latest model race: Fable 5, Mythos, ChatGPT 5.5, long-running agents, open source vs. frontier models, Nvidia vs. ASICs, the AI CapEx boom, and why the market may still be underestimating the scale of AI demand.
