  • • Netflix is viewed as the streaming wars victor with robust global subscriber growth and improving free cash flow; Pershing Square projects ~19% annual EPS compounding.
  • • Visa and Mastercard both receive 10/10 moat scores, characterized as financial "toll roads" with unmatched network effects, high margins, and double-digit earnings growth potential.
  • • S&P Global's multiple competitive moats—ratings, benchmarks, and proprietary data—are deeply embedded in financial markets, with valuations below historical norms and earnings growth expected to reaccelerate.
  • • Ackman's strategy reflects a focus on durable competitive advantages and franchise quality rather than growth-at-any-price positioning in a selective, concentrated portfolio.
Summary
Bill Ackman's Pershing Square Capital is executing a targeted accumulation strategy focused on four dominant businesses characterized by sustainable competitive advantages at attractive valuations. The hedge fund is building positions in Netflix, Visa, Mastercard, and S&P Global—all considered wide-moat enterprises capable of delivering superior long-term returns despite recent market repricing.

Netflix represents a strategic turnaround bet for Ackman, who lost approximately $400 million on the company previously. Pershing Square now views the streaming landscape as consolidated, with Netflix positioned as the clear winner with a robust global subscriber base and meaningfully improved free cash flow generation. The investment thesis projects annual earnings-per-share compounding of approximately 19%, signaling confidence in both current profitability and future growth trajectories.

The dual payment-processing positions in Visa and Mastercard underscore Ackman's conviction in network-based business models. Both companies are characterized as financial "toll roads"—enterprises that benefit from structural network effects, elevated pricing power, and expanding usage volumes. Pershing Square assigns each a maximum 10/10 moat score, reflecting their dominance in global payment rails and capacity to deliver consistent double-digit earnings growth irrespective of broader macroeconomic cycles.

S&P Global rounds out the quartet, offering multiple embedded competitive advantages through its ratings business, benchmark indices, and proprietary market data platforms. These franchises are deeply woven into institutional investment decision-making and regulatory frameworks, creating durable switching costs. While S&P Global's current valuation trades below historical norms, the investment thesis anticipates earnings growth reacceleration, positioning the position as a patient, quality-oriented addition to Pershing Square's concentrated portfolio.

Collectively, these four positions reflect Ackman's systematic approach to identifying franchise-quality businesses with structural pricing power, network effects, or embedded data advantages—characteristics typically resilient across economic cycles and capable of compounding shareholder value over extended periods.
