Trader consensus strongly backs SpaceX as the largest private company at end of June, reflected in its 98.7% market-implied probability. This stems from the company's established valuation leadership, driven by repeated private funding rounds, expanding revenue from launch contracts and satellite services, and sector dominance in aerospace. Capital committed by traders aggregates these fundamentals into a clear edge over peers like OpenAI. While the overwhelming odds signal broad agreement, realistic scenarios such as a major late-month funding announcement or revised valuation for another firm could still narrow the gap before resolution.
