OpenAI’s decision to delay any IPO until 2027, driven by CEO Sam Altman’s emphasis on AI safety priorities, has shaped trader sentiment around the closing market cap. The company is advancing a bridge financing round targeting at least $30 billion at roughly $1.4 trillion valuation—up from the $852 billion post-money level set in its March 2026 raise—supported by rapid revenue expansion to a $40–70 billion annualized run rate. This momentum, alongside the confidential S-1 filing earlier in the year, underpins the 55.4% market-implied probability on a 1.5T+ outcome at listing, while the 23.8% chance assigned to no IPO by December 31, 2027, reflects ongoing uncertainty over safety milestones and regulatory pressures that could extend the private phase.
