Rocket Lab Shares Surge on Backlog Growth and SpaceX IPO Anticipation

Rocket Lab (RKLB) experienced a 28.5% increase in share price during April, fueled by a combination of operational success and broader industry optimism. The surge reflects growing confidence in the company's ability to scale its launch services and capture a larger share of the expanding space economy. The rally was underpinned by several catalysts, including upward revisions to price targets by investment banks and a strengthening backlog. Investors are also pricing in a potential halo effect from the upcoming SpaceX IPO, scheduled for June, which is expected to bring renewed attention to the commercial space sector. The company's backlog has expanded to $1.85 billion, driven by increased demand from both commercial entities and the United States government. Rocket Lab's Electron rocket continues to demonstrate reliability, with two successful launches in April contributing to a record-breaking year. Financially, the company reported total revenue of $600 million for 2025. The primary growth catalyst remains the development of the Neutron rocket, a larger vehicle capable of generating $50 million or more per launch. While a full live test is slated for Q4 2026, any failure could lead to increased cash burn and a loss of market confidence. Despite the momentum—which has seen the stock climb 243% over the past 12 months—valuation concerns are mounting. With a price-to-sales (P/S) ratio of 70, the stock is trading at a significant premium, which may limit further upside in the short term.
