The filing also shows that Willis Towers Watson and Vaxcyte were exited, freeing up capital that appears to have been redeployed in part into CME. Amazon remains the portfolio's lead holding, giving Baupost a lineup that now mixes large-cap tech with a major exchange operator.
CME Group is the parent of the Chicago Mercantile Exchange and runs some of the world's most heavily traded futures and options markets. Klarman's decision to carve out a dedicated slot for the company signals that he sees durable value in exchange-driven, fee-based business models at current prices.
