David Choe, who first spray-painted the walls of Facebook HQ in 2005, accepted shares in payment for his work.
Now the site is planning to float on the stock market, its thought his share could be worth around $200m (£126m).
Writing on his blog, Choe said he was the “highest paid decorator alive”.
Although he had initially thought the idea of the social network was “ridiculous and pointless”, the artist decided to take the stock option instead of cash “in the thousands of dollars” according to the New York Times.
‘Tis all a Chequer-board of Nights and Days
Where Destiny with Men for Pieces plays:
Hither and thither moves, and mates, and slays,
And one by one back in the Closet lays.”
“Let what will be, be.”
‘Tis labor lost thus to all doors to crawl,
Take thy good fortune, and thy bad withal;
Know for a surety each must play his game,
As from heaven’s dice-box fate’s dice chance to fall.”
