Three months ago, Fractile was a freshly minted unicorn. Now it’s apparently trying to become six unicorns stacked in a trench coat.
The London-based AI chip startup is in advanced negotiations to raise approximately $600 million at a pre-money valuation of $6.5 billion, according to reports. That would represent a roughly sixfold increase from the nearly $1 billion valuation it secured during its Series B round in May 2026.
From $1B to $6.5B in one summer
Fractile closed a $220 million Series B in May, co-led by Accel, Factorial Funds, and Founders Fund. The firm had raised somewhere in the range of $241 million to $321 million in total disclosed funding by the time that round wrapped up, including smaller earlier seed rounds.
Now, barely into mid-August, the company is reportedly deep into talks for a follow-on round that would price it at $6.5 billion before the new money even hits the balance sheet. If completed, the raise would bring in around $600 million in fresh capital.
