SpaceX Jumps 11% in Second Day of Trading After Record IPO

The fully exercised overallotment adds another concrete data point. In plain terms, underwriters sold the full block of extra shares available to enlarge the deal, lifting proceeds to $85.7 billion from the initial $75 billion and bringing the added sale to 83.3 million shares.

Those facts point to strong order demand for the offering, though they do not by themselves guarantee lasting support once early trading settles.

The second-day move adds to that picture without proving too much. Shares rose 11% on Monday even after the offering expanded, a notable sign of strong initial appetite at a very large scale.

That is firmer evidence than broad claims about buyers continually stepping in, because the observable fact is simply that the stock finished sharply higher despite the larger supply.

Longtime investor Ron Baron also disclosed a fresh purchase that reinforced the demand narrative. He said his firm bought $1 billion of SpaceX shares in the IPO, lifting its stake to about $25 billion. That does not settle the valuation debate, but it does show that at least one established backer was willing to add capital at the public-market debut.

The bigger question is what investors think they are buying into at roughly a $2 trillion valuation. A price that rich suggests expectations for years of exceptional growth across launch, satellite connectivity and adjacent businesses, not merely enthusiasm for a high-profile listing.

It also leaves less room for operational missteps, slower revenue expansion or any shift in the market's tolerance for ambitious long-duration stories.

Early IPO trading can still be noisy. Tight allocations, momentum and scarcity often influence the first few sessions, and those forces can fade as more stock changes hands.

So while the enlarged deal and the 11% second-day gain indicate a powerful opening reception, they are better read as evidence of strong initial demand than as proof that the stock's aftermarket strength will be permanent.

What the market has established so far is narrower but still striking. Investors absorbed the largest IPO on record, underwriters expanded it further, and the shares climbed again in the next session. For now, that shows size was not an obstacle to demand in SpaceX's opening test as a public company.
