Glean's most recent priced round, a $150 million Series F in mid-2025, established a $7.2 billion post-money valuation, while secondary-market marks as of October 2026 reflect a modest decline to approximately $6.9 billion. The company has achieved roughly $300 million in ARR as of May 2026, up 89% year-over-year from $208 million at year-end 2025 and tripling in roughly 15 months, supported by enterprise adoption across Fortune 500 clients and expansion into AI agents. This growth implies a revenue multiple in the low-to-mid 20s, below many AI peers, amid stable investor composition including Sequoia, Lightspeed, and Wellington. With no new funding round or material corporate event disclosed in 2026 and limited time remaining before October 31, trader-implied odds on near-term valuation increases hinge on any surprise capital raise or positive secondary prints that could reprice the company above the prior $7.2 billion benchmark.
