Harvey, the legal AI startup that barely existed three years ago, is in discussions to raise roughly $500 million in fresh capital at a $15.5 billion valuation. Lightspeed Venture Partners has shown interest in leading the round, according to reports of the ongoing talks.
If completed, the deal would mark a staggering jump from Harvey’s previous raise: a $200 million round at an $11 billion valuation that closed in March 2026, co-led by GIC and Sequoia Capital. That means the company’s implied value would have grown by more than 40% in a matter of months.
A valuation trajectory that defies gravity
Harvey’s ascent through the valuation ranks reads like a speedrun. The San Francisco-based company was valued at $3 billion during its Series D in February 2025. By June 2025, a Series E pushed that figure to $5 billion. Late 2025 brought an $8 billion price tag. March 2026 delivered $11 billion. Now, $15.5 billion is on the table.
Total funding raised by Harvey has already surpassed $1.2 billion, making it one of the best-capitalized AI startups globally. Adding another $500 million would push that figure well past $1.7 billion.
