How to play
Guess what the world's biggest companies are worth
CapItUp is a free daily market cap guessing game. Every day at midnight Eastern there are five new rounds on companies you know, like Apple, Nike, Costco and Netflix. A day takes about two minutes.
The five rounds
- Size it up (rounds 1, 2 and 4). You see one company's market cap and a second company's logo. Drag the square until its area shows how big you think the second company is. If you think it's worth twice as much, make the square twice the area.
- Line them up (round 3). Put four companies in order by one number, like store count, employees, profit or revenue. All four use the same unit, so it's apples to apples.
- Make an estimate (round 5). Type one number, like how many stores Starbucks has. You get another company's number for scale, and a calculator is built in.
Scoring
Each round is worth up to 100 points, so a perfect day is 500. Scoring is about how many times off you are, not how many dollars:
| Your guess | Points |
|---|---|
| Exactly right | 100 |
| 2× too high or too low | 75 |
| 4× off | 50 |
| 8× off | 25 |
| 16× off or more | 0 |
Guessing half the real value costs the same as guessing double. In the line-up round you get points for every pair of companies in the right order.
After each answer
Every reveal shows napkin math: a rough, back-of-the-envelope way to get close to the real number. Over a few weeks you build a feel for how big companies really are.
Where the numbers come from
Market caps update every night from live share prices. Store counts, staff, users and revenue come from each company's latest annual report.
