One name is dominating market chatter right now: the SpaceX (SPCX) IPO (Initial Public Offering). Anticipation ran so high that in the weeks leading up to it, investors began pulling money out of other corners of the market. That triggered a noticeable liquidity drain across several sectors. The hardest hit were the riskier bets — Cryptocurrencies and other high-risk assets bled out substantial amounts. Even a rock-solid name like Micron (MU) slipped ahead of the listing. The real question is whether SPCX genuinely threatens MU, or whether this was just pre-IPO jitters.
What Each Company Actually Does — And Where They Overlap
At first glance, SpaceX and Micron have nothing in common. SpaceX is, above all, a rocket and space venturing company. But the story no longer ends in orbit. Earlier this year, SpaceX acquired xAI, another Elon Musk company, planting it firmly in the AI world too. That is why, despite its lead in space technology, SpaceX now finds itself in some degree of competition with Micron (MU).
Even so, what the two do within the AI sector could hardly be more different. SpaceX's xAI is the force behind X's generative AI chat, Grok. The company also runs an extraordinarily capable data center packed with more than 220,000 Nvidia GPUs. SpaceX recently struck a deal with Google under which Google will pay $920 million per month for AI compute capacity.
Micron (MU), by contrast, makes memory chips — components that are fundamental to AI. Its High-Bandwidth Memory (HBM) is absolutely crucial for AI accelerators such as Nvidia GPUs. In short, where SpaceX sells AI services and compute, Micron builds the hardware that the whole stack runs on.
Which Stock Is the Better Bet
Micron (MU) has been one of the hottest stocks in the US market in 2026. Earlier this month, MU surged to an all-time intraday high of $1089.29. But the buzz around the SpaceX IPO then pulled liquidity out of the market, and MU felt the effect too. The two companies may be on very different paths, yet AI is the one arena where those paths cross.
So which one might perform better over the long run? Look at the chain this way: SpaceX (SPCX) does not build AI chips. It uses Nvidia chips — and those Nvidia chips, in turn, rely on Micron (MU) components. That makes Micron an essential link in the chain, which means SpaceX's own growth ultimately feeds demand for companies like Micron.
One Important Word of Caution
Through all of this, many observers worry that the AI sector may be heading into a dot-com bubble-like situation. In a climate like that, protecting your investments matters more than anything. Do your homework before committing money, and spread your portfolio across different assets so that a single shock cannot wipe you out.
