Space Report, Cursor Close, and 13F Disclosures Fuel the Rally

Per Investing.com reporting this morning, several distinct threads converged on SpaceX at once. Goldman Sachs Global Institute's report The Second Space Age, released earlier this week, projected the global space economy could reach $1.8 trillion by 2035 and identified launch infrastructure as the sector's key upstream chokepoint. That framing lands directly on SpaceX's core space business.

The company also completed its $60 billion acquisition of AI coding startup Cursor on August 14, folding the asset into its SpaceXAI division and reinforcing the AI compute thesis behind Q2's numbers. That quarter saw revenue of $7.81B, AI revenue up 247% year over year to $2.56B, and Starlink subscribers doubling to 12.0M.

UBS also weighed in Monday, reiterating its Buy rating with a $210 price target, citing AI token demand and Starlink expansion, with Starship and V3 satellites accelerating broadband next year and femtocells built into Starlink terminals offering mobile upside. UBS flagged one caveat: success depends on securing scarce low-band spectrum and achieving enough network density, particularly in urban areas where coverage remains challenging.

13F Filings Show Deep Institutional Positioning

Quarterly 13F filings were released on August 14, 2026, showing positions as of June 30, 2026. These are point-in-time snapshots as of that date.

NVIDIA (NASDAQ:NVDA) disclosed 122,764,805 SpaceX shares valued at $20,975,594,582, its second-largest disclosed position behind only Intel.
Atreides Management, run by Gavin Baker, disclosed 27,332,943 shares valued at $4,670,106,641, its single largest disclosed position.
Appaloosa LP, run by David Tepper, opened a new position of 225,000 shares valued at $38,443,500, a toe-in-the-water stake.

Other larger holders include Harvard and Alphabet. The search giant reported a $94 billion position in SpaceX, while Harvard Management reported a $2.2 billion stake.

Nebius and CoreWeave Digest a Violent Run

Over the past week, Nebius rose 47.73% and CoreWeave gained 16.09%. Today's morning dip reads as digestion after a violent run rather than any new news about either firm. As noted earlier, both stocks are regaining ground in afternoon trading.

Nebius's Q2 backed the enthusiasm: group revenue of $582 million (+454% YoY), ARR of $3 billion, and adjusted EBITDA margin of 41%. CoreWeave posted record revenue of $2.6 billion (+112% YoY) with backlog of $104 billion, and CEO Michael Intrator said "Q2 marked the quarter in which we saw margins inflect".

Same-day 13F color: NVIDIA disclosed 47,213,353 CoreWeave shares valued $4,699,617,158, equal to 10.29% of the class, and 1,190,476 Nebius shares valued $328,773,757, while Appaloosa opened a new CoreWeave position of 1,078,248 shares valued $107,328,806.

One read of today's action: money is rotating out of AI capacity renters and into the hardware supply chain that sells into them (we profiled seven of those AI infrastructure suppliers, from power to cooling, in a free report you can grab here). Separately, per 24/7 Wall St. reporting, Intuitive Machines climbed 6% to $20.22 after authorization to proceed on a multi-satellite communications program valued at more than $600 million. The SpaceX rally developed later in the morning session.

What to Watch

Near-term catalysts for SpaceX include the pending $60B Cursor acquisition close scheduled for Q3 2026 and any updates on low-band spectrum flagged by UBS. For Nebius and CoreWeave, watch whether the neocloud group can hold post-earnings gains as backlogs convert to revenue through year-end.
