How much money did Ken Jennings win on Jeopardy?
Total winnings breakdown
- Regular-season winnings: $2,520,700 across 74 games (Ken Jennings official bio)
- Tournament winnings: at least $2.7 million more, including $1 million from the Greatest of All Time tournament (APB Speakers)
- Total combined: over $5.2 million
Comparison to other top winners
Three players dominate the all-time Jeopardy! money leaderboard, each with a different specialty.
| Player | Regular-season winnings | Total winnings (with tournaments) | Streak record |
|---|---|---|---|
| Ken Jennings | $2,520,700 | Over $5.2 million | 74 games |
| Brad Rutter | $55,102 | Over $4.9 million | No streak (won tournaments) |
| James Holzhauer | $2,464,216 | Over $2.9 million | 32 games |
The pattern: Jennings leads in streak length, Rutter in tournament earnings, and Holzhauer in single-game cash record ($131,127). For a fan wondering who is the “greatest” in terms of pure money, the answer depends on whether you count regular season or tournament play.
Jennings’ $5.2 million total is the highest of any contestant, but Brad Rutter won more tournament money without ever losing a regular-season game. The debate over “greatest” hinges on whether you value streak length or overall earnings.
The implication: Jennings leads in total cash, but the title “greatest” remains subjective because different players dominate different metrics.
What religious faith is Ken Jennings?
Membership in the Church of Jesus Christ of Latter-day Saints
- Jennings is a practicing Mormon (LDS) (Ken Jennings official bio)
- He served a two-year Mormon mission in Madrid, Spain (Ken Jennings official bio)
Public statements about his faith
Jennings has discussed his faith in interviews and his book Brainiac. He has described how his Mormon background shaped his work ethic and his approach to trivia. The public record is clear: he is a member of the LDS Church and has spoken about it openly.
What question did Ken Jennings lose on?
Final Jeopardy! clue from November 30, 2004
- The clue: “Most of this firm’s 70,000 seasonal white-collar employees work only four months a year”
- Jennings bet $5,601 and answered incorrectly, ending his 74-game streak (Ken Jennings official bio)
- The correct response: “What is H&R Block?”
- Jennings’ answer: “What is FedEx?”
That single moment ended a streak that had made him a television folk hero. The irony: he lost on a tax-preparation firm — a fitting trivia punchline.
What does Ken Jennings do now?
Current role as co-host of Jeopardy!
- Named permanent co-host in 2022 (Britannica)
- Previously served as consulting producer and interim host after Alex Trebek’s death (Ken Jennings official bio)
Other media appearances and writing

What IQ does Ken Jennings have?
No verified IQ score exists
- Ken Jennings has never publicly confirmed an IQ test score (BrainManager)
- Claims of a specific IQ number (e.g., 170+) are estimates, not disclosed scores (BrainManager)
Speculation based on his game show performance
Some websites estimate Jennings’ IQ at 170 or higher, but these are not sourced from any official test. The low confidence in these estimates means they belong in the “unclear” category. His quiz show success is attributed to knowledge, preparation, and strategy — not a known IQ score.
For a fan seeking a simple “IQ number” for Jennings, the honest answer is: no verified figure exists. The speculation damages the credibility of any article that presents it as fact.
The pattern: Jennings’ quiz show success comes from knowledge and strategy, not from a disclosed IQ score.
Who is considered the greatest Jeopardy player of all time?
Ken Jennings’ record
- Longest winning streak: 74 games (Ken Jennings official bio)
- Won the Greatest of All Time tournament in 2020 (APB Speakers)
Comparison with other top players
Three players — Jennings, Brad Rutter, and James Holzhauer — each hold a different crown.
| Player | Streak | Regular-season cash | Tournament cash | Single-game record |
|---|---|---|---|---|
| Ken Jennings | 74 games | $2,520,700 | $2.7M+ | $75,000 |
| Brad Rutter | Never lost | $55,102 | $4.9M+ | $55,102 |
| James Holzhauer | 32 games | $2,464,216 | $400K+ | $131,127 |
The pattern: Jennings owns the streak, Rutter owns the tournament earnings, Holzhauer owns the single-game record. The “greatest” title is subjective, but Jennings’ tournament victory over both rivals in 2020 gives him a strong claim.
