SpaceX's completed June 2026 IPO, which priced near $1.8 trillion and surged above $2 trillion on debut, anchors trader consensus at 93.7% for the higher IPO market cap outcome. The aerospace company's revenue from Starlink subscriptions, launch contracts, and AI-related initiatives supported aggressive valuation multiples, while OpenAI's most recent private round reached only $852 billion with plans now leaning toward a 2027 debut. OpenAI continues to report strong annualized revenue near $25 billion from its large language models and ChatGPT enterprise usage, yet governance restructuring and competitive pressures from rivals like Anthropic have slowed its timeline. A faster-than-expected OpenAI listing with a substantial first-day pop remains the clearest risk to the current market-implied odds.
