Here’s today’s Final Jeopardy (in the category Businesses) for Wednesday, November 12, 2025 (Season 42, Game 48):
A 2018 book about this company once valued at $9 billion was titled “Bad Blood”
(correct response beneath the contestants)
Today’s Jeopardy! contestants:
Lynette Perloff, an assessment specialist originally from Philadelphia, Pennsylvania
|
Greg Saunders, an insurance reinspector from Bridgeport, Connecticut
|
Harrison Whitaker, a researcher originally from Terre Haute, Indiana (1-day total: $34,801)

Andy’s Pregame Thoughts:
Yesterday, Harrison Whitaker ended the 4-game win streak of Allegra Kuney; today, he defends for the first time against Greg Saunders (no relation!) and Lynette Perloff.
Also, as we get closer to the Tournament of Champions cutoff, here are the postseason stakes for today’s game: If either challenger wins today, Aaron Levine clinches his spot in the Tournament of Champions. (The only way that Aaron doesn’t clinch is if Harrison wins exactly 3 games, losing on Friday, and surpasses $49,000 in winnings.) If Harrison wins for the rest of the week (making it to 4 wins), he’ll be held over until the 2027 postseason.

Correct response: What is Theranos?
More information about Final Jeopardy:

Theranos was a multibillion-dollar biotech founded by Elizabeth Holmes, who claimed to have developed a method of testing blood from very small quantities; by 2015, the company was valued at $9 billion. However, academics and journalists began investigating the claims, with Wall Street Journal journalist John Carreyrou publishing investigative articles, and later Bad Blood: Secrets and Lies in a Silicon Valley Startup, a book chronicling Theranos’s rise and fall.
It’s tough for me to predict how business-related clues will play in Final Jeopardy; a number of the greats of the game have fallen to this category. That said, this Final felt relatively straightforward to me; I was able to figure it out with only cursory knowledge of the Theranos scandal.

Great book. Made me hate and feel sorry for Elizabeth Holmes at the same time. Yes, got this right away.
