Robert and I are thrilled that our gift of over 2 million shares of SpaceX stock will be distributed to children’s Trump accounts in December!
Our initial gift (shares transferring to escrow as we speak) will go to 11 to 17-year-olds who live in zip codes with median family income (MFI) of $57,000 or less, and to those who live in zip codes with too few residents for an MFI to be reported in the census. These families should receive a notice by Monday.
In a few weeks, an additional gift will be finalized for eligible 11 to 17-year-old children in military families serving overseas, children in foster care, and more children whose MFI is $90,000 or less living in counties near our home in the great state of Texas.
Thank you to the incredible team @SpaceX, @Treasury, @IRS, @DellFdn, @GreaterHorizons, @InvestAmerica24, and the legal firms of Morgan Lewis and Gibson Dunn for working over the past few months to make this happen.
We are deeply grateful for the groundbreaking work that Brad Gerstner @altcap and @MichaelDell have done for the long-term financial security for millions of kids.
God Bless America!

AI’s next bottleneck is power. @dfjgrowth is thrilled to back @ambrosiaenergy, building modular, off-grid solar + battery plants for AI workloads. Honored to partner with Benjamin Longmier @longmier, Sara Spangelo @sara_spangelo, & the Ambrosia team.

Weeeelllll, I guess @Starlink Mobile is doing something right! It’s David and Goliath (X3) all over again — I’m bettin’ on David :)
Verizon, AT&T and T-Mobile said on Thursday they agreed in principle to form a new JV with an aim to address long-time coverage gaps, especially in rural areas, by using satellite-based technologies.
This comes as the industry increasingly worries about what Elon Musk’s @Starlink Mobile might do to shake up the terrestrial mobile space.
Musk has said he’s not going to put the U.S. terrestrial carriers out of business, but at the same time he’s expanding Starlink and buying up more spectrum...

Getting to space was step one.
Tom Mueller @lrocket helped power SpaceX to orbit. Now, with Impulse Space @GoToImpulse, he's solving the harder problem — moving through space with the precision it demands.

TIME’s new cover: SpaceX is racing to build its most powerful rockets yet with the goal of returning humans to the moon. Gwynne Shotwell is leading the charge alongside Elon Musk. Read it here: time.com/article/2026/03/26/…

Fun time chatting defense tech investing with @StevenSimoni on @DroneUltimatum Podcast - thanks for having me!
We cover what we @dfjgrowth look for as long time VCs in the category, how the battlefield is changing and the pressing need for defense innovation (shout out to portcos @SpaceX @anduriltech @VannevarLabs @hiddenlevelinc @GoToImpulse), & how startups can most effectively partner and scale w the government.
Space-based data centers make total sense, especially with low cost launch and high mass to orbit via Starship.
The sun offers a free, abundant and clean energy source that can be harnessed through massive solar arrays to power satellite AI data centers.
The climate in space offers a natural source of cooling & ventilation for AI compute clusters.
Then you launch a constellation of solar-powered satellites that have have embedded power and cooling advantages. The satellites each house a GPU farm for AI computing/processing. The satellites will have high frequency up and downlinks plus wideband laser crosslinks to create the ultimate AI network.
And voila…you have a AI compute system in space that serves the massive genAI demand of humanity.

I can’t wait to go to the Moon!
For the first time in our existence, we possess the means, technology, and, for the moment, the will to establish a permanent human presence beyond Earth. Starship is designed to make this future a reality → spacex.com/updates/#moon-and…

So excited for @dfjgrowth be joining the @GoToImpulse team after knowing Tom Mueller since the earliest days of SpaceX. After joining the SpaceX family 16 years ago, we’ve been looking for another opportunity to participate in the intersection of the emerging space economy and the innovation economy. Impulse is it — delivering transformative advancement in propulsion and space vehicle technologies. They are making responsive in-orbit mobility a reality for space logistics and space defense applications. Ad astra!
We’ve raised a $300M Series C to #MobilizeSpace. 🚀
It’s one of the largest venture rounds in space industry history—and it means we’re growing our team and scaling production to keep accelerating in-space mobility.
Since our founding in 2021, we’ve flown two successful Mira missions, signed over 30 commercial and government contracts, and maintained our timeline to deliver Helios in 2026.
We’re building the infrastructure to move anything, anywhere in space. And we’re just getting started.
