BOESKY, Ivan

Ivan Boesky was a Wall Street arbitrageur who became the central figure in the largest insider trading scandal of the 1980s, ultimately serving as a government informant that helped expose widespread corruption in the financial industry. His case exemplified the excess and criminal activity that characterized the decade’s financial markets.

Boesky built his fortune through risk arbitrage, betting on corporate takeovers and mergers using what appeared to be exceptional market timing and analysis. His success made him one of the wealthiest and most prominent figures on Wall Street, known for his lavish lifestyle and his famous declaration that “greed is healthy” in a 1985 Berkeley commencement address.

The Securities and Exchange Commission investigation revealed that Boesky had been receiving inside information from investment banker Dennis Levine and others, allowing him to make guaranteed profits on major corporate deals. When confronted with evidence of his crimes, Boesky agreed to cooperate with federal investigators in exchange for a reduced sentence.

His cooperation led to a broader investigation that ultimately implicated junk bond king Michael Milken, Drexel Burnham Lambert, and numerous other Wall Street figures in a vast network of insider trading and market manipulation. Boesky was fined $100 million and sentenced to three years in prison, though he served only 22 months.

The Boesky scandal contributed to major reforms in securities regulation and helped end the era of unchecked speculation that characterized 1980s Wall Street, while establishing legal precedents for prosecuting white-collar crime in financial markets.
