OpenAI's continued absence of any formal AGI declaration drives the 89.5% market-implied probability for "No" before 2027. Recent model releases such as GPT-5 variants and GPT-5.6 show strong expert-level reasoning and coding capabilities, yet fall short of the broad, autonomous human-level performance across domains that defines AGI. The company's April 2026 publication of five operating principles for AGI development, alongside internal timelines expecting only small scientific discoveries in 2026 and more significant advances in 2028+, signals steady incremental progress rather than an imminent breakthrough. Independent verification requirements in partnerships further raise the bar for any official announcement. Traders view these factors as consistent with historical patterns where ambitious claims precede actual attainment by years.
