Was Grail a good bet for Illumina?

"Grail, which counted Jeff Bezos and Gates among its early backers, has developed one of the world’s first early detection blood tests. The test, which it named Galleri, aims to detect up to 50 different types of cancer, including many that are not part of national screening programmes. It is currently being tested in trials, including a UK National Health Service study involving 140,000 people.”
