SpaceX has almost finished writing V1.0 of an in-house AI training stack in C that exact-maps to 220k GB300s with 800G NICs, making heavy use of pipeline parallelism and getting as close to bare metal as possible.
The potential speed improvement vs JAX for large training runs is over an order of magnitude.
Congrats and a huge thank you to the SpaceX team that always delivers. This was an incredible first flight of a brand new vehicle. Our collective future flying amongst the stars has become so much closer.
WOW! This is the first time we've ever been able to see Starship in space from another object. This view comes from modified Starlink satellite they just deployed that has a camera and a light on it.
Super cool!

A crazy tax idea for Elon Musk.
He could become the biggest OZ investor in history.
The IPO is the trigger.
SpaceX goes public June 12 under the ticker SPCX and the valuation might go to $2 trillion. The largest IPO ever.
Insider lockup runs 180 days. It expires around December 15.
The day it ends, insiders can sell. Every share sold throws off a capital gain. For Elon, holding billions in SpaceX paper, the gain is staggering.
Under the new Opportunity Zone rules that take effect January 1, 2027, any capital gain rolled into a Qualified Opportunity Fund within 180 days of the sale earns a five-year tax deferral.
Sell in late December 2026. Invest in early 2027. The tax bill is not due until 2032.
If the QOF investment is held for ten years, the entire appreciation comes out tax-free. No capital gains. No depreciation recapture. Zero.
But Elon isn't going to suddenly start investing in apartments or hotels in low income areas. He is going to remain obsessed with investing in his core businesses.
Good news.
The town of Starbase, Texas sits inside an Opportunity Zone census tract. Grimes County, where Musk is building a $55 billion semiconductor fab called Terafab, has three OZ tracts of its own.
Elon could sell SPCX shares after lockup. Roll the gain into his own Qualified Opportunity Fund. Use that fund to build infrastructure at Starbase or finance the Terafab site.
Then lease the asset back to the public company.
SpaceX pays the rent. The rent is deductible to SpaceX. The depreciation flows to Elon and offsets his other income for a decade.
Then he sells the QOF interest in 2037.
No tax on the appreciation. No recapture on the depreciation. The original gain that funded it all was deferred to 2032.
The IPO funds the infrastructure. The infrastructure runs the company. The taxpayer pays nothing for ten years and almost nothing forever.
This is the crazy idea.
The mechanics are real. The zones are real. The IPO is real.
I am glad to advise his tax team. 🤠
