Key takeaways
- SpaceX’s Bastrop blade and vane foundry is best viewed as an attempt to secure turbines for its own AI power needs, not evidence that it can soon rival Siemens Energy as a full gas turbine OEM.
- For Siemens Energy, the nearer evidence remains strong demand and execution: Q3 FY2026 orders were a record €17.9 billion, Gas Services orders approached €10 billion, and the company reaffirmed its FY2026 outlook.
- The risk changes materially only if SpaceX moves beyond component self supply into validated, commercial turbine systems with the service, warranty, and customer infrastructure required to compete at scale.

SpaceX’s plan to cast gas-turbine blades and vanes in Bastrop, Texas should be read primarily as vertical integration around a difficult supply constraint. It is not, based on what has been disclosed, confirmation that SpaceX is building a broad industrial gas-turbine business to compete directly with Siemens Energy.
That distinction matters because Siemens Energy shares fell roughly 5% after the news, while other companies exposed to turbine supply also sold off. 19
18 The more durable investor question is whether SpaceX is taking a customer’s place in the supply chain—or building the far broader capabilities required to become an original equipment manufacturer.
What SpaceX has actually signaled
Elon Musk said SpaceX would make natural-gas-turbine blades and vanes in-house because casting those parts is the limiting factor in turbine production. He said the move could accelerate turbines coming online by as much as 18 months, in support of power needs tied to AI data centers. 30

That is meaningful. It shows that access to reliable power equipment has become important enough for a large prospective buyer to build internal manufacturing capacity around a constrained component.
But a blade-and-vane foundry is not the same thing as a full turbine franchise. The disclosed plan concerns components and the speed of supplying SpaceX-linked power projects. There is no provided evidence that SpaceX intends to sell complete turbines broadly, build an installed customer base, or provide the long-term service and warranty infrastructure that supports a commercial OEM business. The case for an immediate competitive threat to Siemens Energy is therefore limited.
Why analysts describe it as self-supply
Reports following the sell-off said JPMorgan, Jefferies and Deutsche Bank characterized the development as self-supply rather than a direct competitive entry against Siemens Energy. 20 Their interpretation is straightforward: a customer facing long waits for a bottlenecked part is trying to control its own delivery schedule.
For incumbent turbine makers, that can have two opposing effects:
- Potential negative: if SpaceX supplies some of its own critical components, it may reduce its need to source those components externally.
- Potential positive: the investment itself validates the seriousness of the supply constraint and the urgency of AI-related power demand.
The second point is particularly relevant to Siemens Energy. SpaceX’s move does not automatically create equivalent capacity for complete heavy-duty turbines, nor does it erase the need for turbine engineering, manufacturing, integration and service support.
Siemens Energy’s order book is the immediate counterweight
Siemens Energy’s Q3 FY2026 results provide a clearer near-term gauge of its commercial position than the prospect of a future SpaceX manufacturing ramp.
The company reported record quarterly orders of €17.9 billion, a 1.57 book-to-bill ratio, and an €162 billion order backlog. A book-to-bill ratio above 1 means orders exceeded revenue in the period, adding to future delivery visibility. 1
12
Gas Services was a major contributor: it recorded nearly €10 billion in orders, up about 62% year over year on a comparable basis. Siemens Energy also reported 69 GW of firm gas-turbine backlog after booking 15 GW and shipping 6 GW during the quarter. 11
1
These data do not eliminate risk, but they show that the company’s current demand and conversion story is far broader than one potential customer’s component strategy.
The investment case is not just gas turbines
The relevant Siemens Energy thesis combines three areas: gas turbines, long-term service, and grid equipment. AI data centers need dependable power, but connecting and operating that power also requires grid infrastructure.
Management reaffirmed its FY2026 outlook and expects profit margin before special items toward the upper end of its 10% to 12% guided range. 12 Siemens Gamesa also reported its first profitable quarter since Q4 FY2022, an important milestone because it reduces the risk that wind-business losses overshadow improvement elsewhere in the group.

This does not make the shares immune to valuation or execution pressure. It does mean that the business case is supported by reported orders, backlog, margin progress and a broader portfolio rather than a single gas-turbine narrative.
Supply is expanding—but not instantly
Siemens Energy has committed $1 billion to expand U.S. manufacturing, including large gas-turbine production and grid equipment. The program includes expansions at existing sites and a new grid-components factory in Mississippi. 38
Capacity additions are strategically important, but they are not immediate. The wider market has been characterized by substantial demand relative to manufacturing capacity: one industry report cited approximately 110 GW of global orders at the end of 2025 against 60–70 GW of manufacturing capacity. 42 Another report described turbine lead times of three years or more and noted Siemens Energy’s plans to move from roughly 20 GW annualized production toward 24 GW by 2028 and 30 GW by 2030.
33
Those are industry estimates, not guarantees about each supplier or project. Still, they help explain why a buyer such as SpaceX would seek to secure a bottlenecked production step internally.
What investors should watch next
The appropriate base case is that SpaceX’s project is a supply-chain response, not a near-term break in Siemens Energy’s competitive position. The thesis would need reassessment if evidence emerges that SpaceX is doing more than captive component production.
Key signposts include:
- Scope and output of the Bastrop facility: Is it designed only for internal needs, or does SpaceX announce external component sales or complete turbine offerings?
- Commercialization: Does SpaceX disclose turbine designs, customer orders, certification, warranties or service operations? Those would be more relevant competitive markers than the foundry announcement alone.
- Siemens Energy order conversion: Watch whether the €162 billion backlog converts to revenue and margins while capacity expands.
1
- Gas Services momentum: New orders, backlog progression and service profitability remain central indicators of whether AI-driven and broader power demand is sustaining the cycle.
- Project economics: Gas availability, permitting, grid interconnection and financing will determine whether data-center power demand turns into installed capacity.
Bottom line
SpaceX’s foundry plan is evidence that turbine blades and vanes have become strategically scarce in the race to power AI infrastructure. That is a real supply-chain development, and it can matter for specialist suppliers and turbine makers.
For Siemens Energy investors, however, the available evidence points more clearly to a customer internalizing a bottleneck than to a new full-line OEM competitor. Siemens Energy’s record orders, €162 billion backlog, rising Gas Services demand, reaffirmed guidance and U.S. capacity investment remain the more immediate facts shaping the investment case. 1
