SpaceX vs. Quantinuum: Which Recent IPO Stock Is a Better Buy?

The article compares two newly public high-profile growth companies, SpaceX (SPCX.OQ) and Quantinuum (QNT), both of which have fallen after their IPOs. It argues SpaceX looks like the better investment because its Q2 2026 revenue surged 92% year over year to $7.8 billion, its operating loss improved sharply, and its valuation (73x sales) is lower than Quantinuum’s 99x sales. Quantinuum’s Q1 revenue plunged 73% to $5.2 million, and losses widened to $77.2 million, though it still has strong cash reserves and won a $100 million U.S. government award. The piece notes that both companies operate in promising but early-stage sectors, and that SpaceX’s AI segment is growing rapidly, but its heavy capex of $18.4 billion and $25 billion bond issuance raise funding concerns. Overall, the article is a bullish long-term endorsement of SpaceX relative to Quantinuum, while acknowledging elevated risk and valuation for both.
