SpaceX is accelerating its IPO—reportedly targeting a June 12, 2026 debut under the ticker SPCX. While the mega-listing has already supercharged pure-play competitors like Rocket Lab (RKLB), investors treating RKLB as the "last entry point" to the space rally should proceed with extreme caution.The June 12 SpaceX IPO threatens to suck the air—and capital—out of the broader retail space market, meaning the recent RKLB surge could be heavily overextended. Here’s why chasing this RKLB run might be a risky move:Valuation Stretched Thin: RKLB hit all-time highs above \(\$130\) before pulling back. At over 90x sales, much of its long-term growth is already priced in, making it vulnerable to broader tech market sell-offs.Neutron Hype: The stock's massive momentum isn't just because of SpaceX; it hinges on the success of Rocket Lab’s heavy-lift Neutron rocket, which has an inaugural flight slated for late 2026. That binary risk means the stock is heavily pricing in future perfection.The "SpaceX Effect": Historically, mega-IPO debuts can trigger short-term post-listing pullbacks as institutional money reallocates. The true public SpaceX alternative is fundamentally different from Rocket Lab's small-cap reality, meaning the space sector could divide into "haves and have-nots" once SpaceX hits the Nasdaq boards.Verdict: Chasing Rocket Lab at these premium valuations isn't necessarily a safe substitute for missing out on SpaceX. Prospective investors might want to wait for the post-IPO volatility to settle before initiating a position.
