Rocket Lab stock’s driver today is harder to pin to a single data point, but it’s real. Speculation around a SpaceX public listing continues to build, and prediction markets are pricing it seriously.

On Polymarket, traders assign a 51% implied probability to SpaceX closing its IPO above a $2 trillion market cap, with the >$2.4 trillion bracket sitting at 38% probability and showing a 9% positive price change over the past week alone. Thus, the market is not treating a SpaceX IPO as a distant hypothetical.

When SpaceX eventually goes public, it will almost certainly trigger a broad re-rating of space stocks. Investors who missed SpaceX’s private run will look for the next best thing, and Rocket Lab is the most credible publicly traded pure-play in the sector; this halo effect is part of what’s lifting RKLB shares today.

This isn’t a story running purely on narrative, as Rocket Lab just closed its strongest financial year on record. CEO Peter Beck put it directly on the Q4 earnings call:

“2026 was a record-breaking year for Rocket Lab financially and operationally. We delivered record quarterly revenue of $180 million, which brought our full year revenue to a record $602 million, representing 38% growth year on year.”

The backlog tells the same story. Rocket Lab ended 2025 with $1.85 billion in backlog, up 73% year over year, anchored by an $816 million Space Development Agency contract for 18 satellites.

The company also secured selection by the Missile Defense Agency for the SHIELD program, with potential contracts up to $151 billion. That’s not small-satellite launch revenue; it’s substantial defense infrastructure money.

Moreover, Rocket Lab’s forward guidance for Q1 2026 calls for revenue of $185 million to $200 million, implying roughly 57% year-over-year growth at the midpoint. Analysts maintain a consensus “Moderate Buy” on RKLB shares with an average target of $75.92, though that figure is below where the stock is trading this morning. The stock’s 52-week high sits at $99.58, giving bulls a clear target to point to.

The stock’s long-term trajectory is striking. RKLB has gained 279.11% over the past twelve months, moving from $18.81 to $71.31 before today’s session. That kind of run invites skepticism, and the insider selling data is worth noting: 84 recent insider transactions with a net selling direction is a contrarian signal that analysts and observers have noted.

Today’s surge puts RKLB stock back near levels it last saw before a quiet consolidation period. Price action into the close and any additional Neutron program updates or SpaceX-related news flow could influence how the stock finishes the session and continues through the week.

Most Americans drastically underestimate how much they need to retire and overestimate how prepared they are. But data shows that people with one habit have more than double the savings of those who don’t.

And no, it’s got nothing to do with increasing your income, savings, clipping coupons, or even cutting back on your lifestyle. It’s much more straightforward (and powerful) than any of that. Frankly, it’s shocking more people don’t adopt the habit given how easy it is.
