Instinct raises $1 billion Series C at a $10 billion valuation, one month after its Series B

Instinct confirmed a $1 billion Series C on 28 September 2026 at a $10 billion valuation, with Sequoia Capital, Benchmark, and Coatue investing, four weeks after a $250 million Series B at $2.5 billion and roughly six months after the operating company's April registration in California. The release named no lead investor and disclosed no revenue or pricing; reporting before the close put the invite-only personal agent past 100,000 users in mid-September.

Bar chart of Instinct's valuations by round: 50 million dollars in April, 500 million in early August, 2.5 billion on 26 August, 10 billion on 28 September, with about 1.35 billion raised in total

What it means for buyers

Consumer agent platforms are now the best-funded slice of the market our personal-ai-agents comparison tracks: Instinct, Meta's Muse, and OpenAI's Dots all carry billion-dollar backing while staying gated behind invites or paid tiers. The round also sharpens the containment question this comparison treats as a first-class column, because an agent that books, buys, and cancels with legal authority is exactly the design the week's safety news responds to, so our guidance pairs Instinct's capability claims with what its terms actually bind you to.
