Dang that slanderous Guardian describing Manifund as a prediction market when it's a market where people make predictions. Totally misleading!
Since Ivan owns 50% of the project's certs, his stake has tripled in value from $3,000 to $9,000; he sells them for $9,000 to The Good Foundation, netting a $6,000 profit. (Important note: for legal reasons, profits on Manifund impact certificates can currently only be used to donate to charity and can't be cashed out in the normal way.)
