Rocket Lab fell 7% and Intuitive Machines dropped 15% in Wednesday trading after SpaceX confirmed its IPO pricing at $135 per share, establishing a $1.77 trillion enterprise value that arrived roughly 10% below the $150 whisper number circulating among late-stage allocators since February. The sector-wide selloff erased $2.1 billion in aggregate market capitalization across the six publicly traded space-infrastructure names, with volatility spiking to 38% intraday for the small-cap operators.

The pricing signal matters less for what SpaceX commanded and more for what it denied the peer set. Allocators had modeled Rocket Lab and Intuitive Machines at forward revenue multiples of 12x and 18x respectively, anchored to assumptions that SpaceX would clear $160 and validate the sector's post-SPAC survivors as legitimate growth proxies. Instead, the $135 print resets the comparable-company watermark 12% lower, compressing the multiple expansion thesis that had driven both names up 34% and 41% year-to-date through Tuesday's close. The repricing was mechanical: when the flagship clears below expectation, the subscale operators lose their scarcity premium.

What separates this from routine sector rotation is timing. SpaceX's IPO lands three weeks before Rocket Lab reports Q1 earnings on April 28 and six weeks ahead of Intuitive Machines' May 12 call, both of which were expected to guide upward on NASA contract extensions worth a combined $470 million over eighteen months. Those catalysts now face a 15-20% higher bar for surprise, because the Street's revised base case already discounts the contract wins at lower exit multiples. Meanwhile, the $1.77 trillion SpaceX valuation—seventh-largest in the U.S., above Tesla's $1.6 trillion—creates an optical problem for allocators pitching space exposure to family offices: the risk-adjusted return now lives entirely in the Musk vehicle, not the fragmented also-rans. Liquidity follows concentration.

Operators should track two follow-on events within 30 days: first, whether SpaceX's post-IPO trading volume sustains above 40 million shares daily, which would signal institutional accumulation and further pressure on smaller names as allocators rotate out of subscale positions; second, whether Rocket Lab's April earnings call includes updated 2026 margin guidance above the current 18% target, the only fundamental lever capable of reclaiming valuation ground independent of sector sentiment. If neither materializes, the repricing becomes structural.

The IPO itself trades next week, likely Tuesday or Wednesday. The $135 price already reflects reality. What remains unpriced is whether the public comps can justify their survival as standalone vehicles or whether the sector consolidates around the only name with both margin and mission.
