Tesla Roadster Demo Shows SpaceX Tech; xAI Says Colossus Uses Tesla Megapacks
Published October 16, 2026 · Sources rechecked October 16, 2026
Tesla unveiled its next-generation Roadster on Thursday, The Wall Street Journal reported. Its account describes the car briefly taking flight using SpaceX technology.
The demonstration put one Tesla–SpaceX technology connection on public display. The Wall Street Journal reports that production is planned for 2028, but that goal does not establish when customer cars will reach buyers or what financial benefit either company may receive.
Separately, xAI says it has installed well over 200 Tesla Megapack battery units at Colossus, its AI computing site in Memphis. xAI says the batteries provide backup power and help the site handle periods of peak electricity demand. Its page does not give the system’s total storage capacity, purchase price, contract details, whether Tesla directly supplied the units, or any revenue Tesla may receive. Fjord Journal has not independently confirmed the count or the system’s performance.
What the two connections show
SpaceX said in February that it had acquired xAI. That connects SpaceX and xAI, but does not mean Tesla owns or operates Colossus. The battery statement is a separate claim by xAI about Tesla-branded equipment at its site.
What it means for Tesla investors
The Roadster event shows technology being used together in a demonstration; it does not establish the finished car’s performance, road legality or when deliveries will begin. The Megapack statement points to a possible Tesla product sale, but without details about the supplier, price or Tesla’s revenue, the financial value is unknown.
Investor takeaway: The Roadster demo and the Colossus batteries are two distinct connections. Both involve Tesla, but the public information does not yet show what either means financially for the company.
What to watch: Confirmed details about Roadster deliveries, and any new information about Colossus’s battery capacity or Tesla’s role in supplying it.
