SpaceX president and COO Gwynne Shotwell has publicly defended CEO Elon Musk after a documentary portrayed the billionaire as deeply unhappy.

Shotwell, who joined Space Exploration Technologies Corp (NASDAQ: SPCX) in 2002 as its 11th employee, took to X to support Musk’s mother, Maye Musk, who rejected the film’s characterization. "I’m with Maye!" Shotwell wrote. "Elon is extraordinary and (I know you’ve heard this) I love working for him (coming up on my 24th year doing so)."

She added, "I don’t love being around miserable people. Elon isn’t one of them."

Response to Documentary Claims

The controversy stems from Oscar-winning filmmaker Alex Gibney’s upcoming nearly four-hour documentary. The Hollywood Reporter previewed the film, citing an unnamed person who worked closely with Musk as describing him as "the most miserable man I’ve ever met."

Musk pushed back on the suggestion in an X post, offering his own assessment of his emotional state. "I’m happy about half the time, somewhere in the middle about 40% and sad about 10% of the time," Musk said.

Maye Musk also rejected the characterization, calling it "weird" and stating, "I haven’t seen him miserable, but that’s just me. His mom."

Shotwell’s Stake and Tenure

Shotwell’s long-standing role at SpaceX has contributed significantly to her personal wealth. According to Forbes, she currently has a net worth of about $1.9 billion.

Shotwell is estimated to own a 0.11% stake in SpaceX. In June, she was featured on Forbes’ list of America’s Richest Self-Made Women, ranking among 43 women billionaires mentioned by the outlet.

What the Numbers Show

Shotwell’s 0.11% equity stake in SpaceX underpins her reported $1.9 billion net worth. This valuation implies a total company equity value of approximately $1.73 trillion based strictly on these two disclosed figures, highlighting the massive scale of capital appreciation for early employees despite small fractional ownership.

SpaceX is constructing a foundry in Bastrop, Texas, to cast blades and vanes for industrial gas turbines. The move aims to circumvent supply chain bottlenecks that are delaying the deployment of power infrastructure critical for artificial intelligence data centers.

Elon Musk confirmed on X that SpaceX is bringing the casting process in-house. He stated this vertical integration could accelerate the commissioning of natural-gas turbines by up to 18 months. The facility addresses a specific constraint in the manufacturing of components required for high-capacity energy generation. Musk noted that natural gas will still be needed to "supplement and bootstrap solar for several years," calling the result a "profound game-changer."

GE Vernova Supply Chain Pressure

GE Vernova Inc. (NYSE: GEV) has highlighted similar supply chain limitations. CEO Scott Strazik noted that the company has pressured suppliers to expand capacity to meet rising turbine demand. In summer 2024, GE Vernova instructed suppliers to increase output, providing capital for new furnaces in some instances.

GE Vernova is aiming to raise annual turbine production from approximately 20 gigawatts this year to 30 GW by the end of the decade. Strazik indicated that reaching 24 GW of annual output by 2028 depends on securing additional castings and forgings by 2027. Only a handful of companies can produce these highly specialized blades, which operate at temperatures of roughly 3,000 to 3,600 degrees Fahrenheit, requiring sophisticated casting techniques that are difficult to replicate quickly.

AI Power Demand Drivers

SpaceX has committed more than $2.8 billion to gas turbines over three years to support its Colossus data centers near Memphis. Manufacturing blades and vanes internally pushes the company further upstream into the supply chain segment that currently restricts delivery speeds. This effort connects to broader ambitions, including the development of Terafab, an ambitious semiconductor manufacturing project in Texas.

The broader context involves intensifying competition for power resources. Data Center Map lists 4,767 U.S. data centers. Kalshi traders assign a 66% probability that this number will reach at least 5,300 by year-end. This implies hundreds of additional facilities will compete for electricity capacity in the coming months. GE Vernova’s turbine business has seen orders extending into 2030.

What the Numbers Show

The divergence between GE Vernova’s production targets and its dependency on external casting capacity highlights a structural constraint in the industrial gas turbine sector. While GE Vernova plans to scale production by 50% over the decade (from 20 GW to 30 GW), its ability to hit the intermediate 24 GW target in 2028 is explicitly tied to supplier capacity expansions scheduled for 2027. SpaceX’s entry into component manufacturing suggests that hyperscalers may increasingly bypass traditional OEM supply chains to secure power infrastructure timelines. SpaceX is applying a philosophy of controlling physical systems around compute, from manufacturing to power, rather than simply buying hardware or leasing capacity.
