Whale Rock CEO: Anthropic to Hit 500M Users Before IPO

Alex Sacerdote, founder and CEO of Whale Rock Capital Management, thinks Anthropic is on track to hit half a billion users before it goes public. That's not a typo — five hundred million, with a B-shaped shadow looming behind it. Sacerdote made the projection at the Sohn Montreal investment conference on June 4, one day after Anthropic filed a confidential IPO registration with the SEC. The timing was not subtle.

From 2 million to 14 million, and counting According to Sacerdote, Claude's user count surged from 2 million to 14 million in a relatively short window. That's a 7x jump, the kind of curve that makes venture investors start breathing a little faster and quietly mutter "number go up" under their breath. Anthropic has tapped Morgan Stanley and Goldman Sachs as lead underwriters for the offering.

The $380 billion valuation Whale Rock isn't just cheerleading from the sidelines. The firm participated in Anthropic's Series G funding round, which closed on February 12, 2026. That round raised $30 billion and valued the company at $380 billion post-money. Whale Rock Capital manages approximately $8 billion in assets and runs a long/short strategy focused on technology, media, and telecom.

Why this matters beyond Silicon Valley The confidential SEC filing on June 3 means the IPO process is formally underway, though the exact timeline and pricing remain undetermined. Confidential filings let companies receive SEC feedback on their registration statements before making financials public — a common playbook for high-profile tech debuts.
