- SpaceX IPO speculation targeting a nearly $2 trillion valuation has fueled retail interest in smaller space stocks, with a Stocktwits poll of 3,100+ votes showing RKLB (39%) and ASTS (38%) as retail favorites over five years
- Space stocks surged in May: Rocket Lab (RKLB) up 83%, Sidus Space (SIDU) +82%, ASTS +68%, and BlackSky (BKSY) +54%, with FTSE Russell's proposed faster index-entry rules for mega-cap IPOs adding to the catalyst
- Sidus Space (SIDU) priced a $100M offering of 19.7M shares at $5.08 under Nasdaq at-the-market rules, sending shares down 20% overnight — yet Koyfin consensus still shows ~64.5% analyst upside, the only one of the four with implied upside
- Rocket Lab secured an additional $816M Space Development Agency contract for missile-tracking satellites (total now $1.331B) and expanded through acquisitions of Motiv Space Systems, Mynaric, Geest, Optical Support, and SolAero
- AST SpaceMobile advanced its BlueBird rollout with satellites arriving at Cape Canaveral for a SpaceX launch campaign; CEO Abel Avellan reiterated plans to deploy 45 satellites this year as a direct-to-smartphone broadband competitor to Starlink
- Stocktwits data shows SIDU retail sentiment as 'extremely bullish' with message volume surging 831% in a month, far outpacing ASTS (327%), RKLB (121%), and BKSY (14%) chatter growth
Why it matters: The SpaceX IPO catalyst is pulling retail capital into small-cap space stocks, but the analyst/retail divergence is sharp: SIDU is the only one of the four names with implied upside (~64.5% per Koyfin) yet just dropped 20% on a $100M dilution offering — a tension between retail euphoria and near-term share supply that will define trading in the cheapest name of the group.
