Who is the world’s youngest self-made billionaire?

At 27, Shayne Coplan has become the world’s youngest self-made billionaire. His estimated 11% stake in Polymarket, the blockchain-based prediction platform he founded in 2020, is now worth at least $1 billion, Forbes writes.

New York Stock Exchange parent company, Intercontinental Exchange, announced it poured $2 billion into the firm at a $9 billion valuation—in exchange for a 20% stake.

The deal caps a meteoric ascent for Polymarket, which was valued at just $1.2 billion earlier this year and has quietly become crypto’s fastest-growing startup.
