Meta’s public market capitalization near $1.88 trillion as of early October 2026 underpins the 92.5% trader consensus, reflecting its established revenue base exceeding $228 billion trailing twelve months, consistent profitability, and steady share-price performance amid AI infrastructure investments. OpenAI’s most recent closed round valued the company at $852 billion post-money in March, with secondary marks around $876 billion in October and early-stage talks for a $30 billion bridge round at roughly $1.4 trillion pre-money still pending; even if completed, the resulting valuation would remain below Meta’s current level. Factors reinforcing the gap include OpenAI’s delayed IPO timeline into 2027 and Meta’s scale advantages in monetization. A completed OpenAI funding round materially above $1.4 trillion or a sharp Meta share-price decline could narrow the differential before year-end resolution.
