Stripe’s implied valuation has climbed sharply in secondary markets to the $180–199 billion range as of late October 2026, well above the $159 billion level set in its February tender offer. Recent Forge and MSCI marks reflect robust bid interest and trading volume, supported by 2025 revenue of $6.8 billion (up 33 percent year-over-year) and strategic moves into AI-agent payments, including the $7.5 billion OpenRouter acquisition. Founders have signaled a preference for remaining private, while secondary platforms show continued momentum from embedded finance and cross-border volume growth. With resolution imminent, traders are monitoring the latest private-share prints and any end-of-month marks that could confirm or reverse the upward trajectory.
