Rocket Lab Takes On SpaceX: Inside the US$8bn Iridium Deal That Changes Everything

Rocket Lab (NASDAQ:RKLB) just made the biggest bet of its life. The company announced it will buy satellite communications operator Iridium (NASDAQ:IRDM) for around US$8 billion, and investors loved it: RKLB jumped almost 16% when the deal broke, then climbed further to around US$102. So why is this deal such a big deal, and can Rocket Lab really take on SpaceX?

From Rocket Maker to Space Powerhouse

Until now, Rocket Lab has been known mainly for one thing: launching rockets and building spacecraft. Iridium changes that completely. Iridium runs a global network of satellites that provide phone, data and tracking services to more than two million customers, including governments and militaries.

Buying it turns Rocket Lab into what the industry calls a “vertically integrated” space company. In plain terms, that means it can now do the whole job in-house: build the satellites, launch them, and then run the services they provide. CEO Peter Beck described Iridium as the missing piece that makes Rocket Lab a full end-to-end space company.

This is exactly the model that made SpaceX so powerful. By controlling the entire chain, Rocket Lab can win bigger, longer contracts and earn steady service revenue instead of relying on one-off launches. For investors, that’s the real prize: a more predictable, higher-value business.

Why the Market Cheered

The market’s enthusiasm makes sense. Iridium is already profitable with millions of paying customers, so it instantly adds real revenue and cash flow to Rocket Lab, which is still loss-making. Management says the deal will boost profitability from day one.

Wall Street quickly turned more positive. Roth MKM lifted its price target to US$130, pointing to Rocket Lab’s stronger competitive position. It’s also worth noting how hard-fought the deal was: analysts say Rocket Lab outbid rivals, including Amazon and AST SpaceMobile, to win Iridium, a sign of how valuable these satellite assets have become.

There’s a debate worth flagging, though. Not everyone agrees this is a straight SpaceX-versus-Rocket-Lab showdown. Some analysts argue Iridium expands Rocket Lab’s services rather than directly challenging SpaceX’s Starlink internet network. Both views can be true: Rocket Lab is becoming a broader space player, and that naturally puts it in more direct competition with the industry’s giant.

The Risks Investors Should Watch

This is where a cool head helps. First, the deal won’t close until mid-2027 and still needs shareholder and regulatory approval, so nothing is guaranteed. Second, buying a big company and blending it into your own is hard, and integration often takes longer and costs more than expected.

Then there’s valuation. Even after the pop, Rocket Lab trades at very high multiples of its sales and remains unprofitable, so a lot of future success is already priced in. The stock is also still down about 33% from its May high near US$150, a reminder of how volatile these space names can be.

Our view: this is a genuinely transformative deal that gives Rocket Lab real scale and a clearer path to profit. But it’s a long game; the benefits arrive over years, not weeks, and the risks around approval, integration and valuation are real. This suits growth investors who believe in the space economy and can stomach big swings, not the cautious ones.

The bottom line: Rocket Lab just bought itself a seat at the top table of the space race. Whether it can truly rival SpaceX now depends on execution, and that story will play out over the next few years, not the next few days.
