Peter Rudegeair / Wall Street Journal:
London-based Checkout.com, which offers payment processing tools, raises $1B in a share sale, sources say at a $40B valuation  —  The $1 billion deal vaults the digital-payments processor past all but a handful of other startups  —  Checkout.com didn't raise money from outside investors until 2019.
