E368: Sovereign 2.0: How Mubadala Capital Is Reinventing the $430B Playbook w/CIO Oscar Fahlgren

What if the biggest source of alpha for taxable investors isn’t stock picking—but minimizing friction inside the portfolio itself? In this episode, I sit down with Brent Sullivan, independent tax analyst and author of one of the leading research platforms on tax-aware investing, to discuss why tax alpha has become one of the fastest-growing themes in wealth management. Brent explains how long-short tax-loss harvesting strategies evolved from niche institutional products into mainstream planning tools, why tracking error is often misunderstood, and how sophisticated investors think about balancing risk, leverage, and after-tax returns. We also explore trader funds, operational risk, and why tax management may matter more than active management for many investors.

What if the key to outperforming isn’t taking more risk—but building a portfolio strong enough to survive volatility without breaking? In this episode, I sit down with Doug Hanly, CIO of the Louisiana State Police Retirement System, to discuss why liquidity, simplicity, and process are the foundations of durable investing. Doug explains why he views short-term government credit as the “supply depots” of a portfolio, how preparation during calm periods creates opportunities during crises, and why avoiding mistakes matters more than chasing complexity. We also explore governance, manager selection, portfolio construction, and how small incremental improvements compound into long-term outperformance.

What if the best investment opportunities are the ones most investors avoid because they’re too hard, too small, or too inefficient to pursue? In this episode, I sit down with Raphael, Deputy CIO and Co-Leader of HighVista Strategies, to discuss the concept of “beautifully inefficient” markets and why durable alpha often exists where few investors are willing to spend time. Raphi explains how governance structures shape investment outcomes, why lower middle market private equity and biotech remain compelling, and how long-duration capital creates structural advantages in venture investing. We also explore continuation vehicles, portfolio concentration, and why the best allocators balance diversification with conviction.

What if the best venture investments come from ignoring consensus and trusting your own taste before the market catches up? In this episode, I sit down with Maya Bakhai, Founding Partner of Spice Capital, to discuss how cultural intuition, narrative cycles, and conviction shape venture investing. Maya explains how working with Kevin Durant at 35 Ventures gave her access to top-tier deal flow while teaching her to think independently, why “narrative premiums” distort venture markets, and how the best founders build with unconditional conviction long before a category becomes popular. We also explore cultural arbitrage, creator economy investing, and why early-stage venture is ultimately a game of taste, not consensus.

What if the biggest winners in AI won’t come from having the best model—but from building the strongest feedback loops around users? In this episode, I sit down with Hans Tung, Managing Partner at Notable Capital and longtime Midas List investor, to discuss how decades of investing across consumer internet and global technology shaped his thesis around AI. Hans explains why Anthropic stood out early through its developer ecosystem, how network effects emerge inside AI systems, and why the most enduring companies are built around positive feedback loops. We also explore physical AI, prosumer behavior, immigrant founders, and the psychological traits required to build category-defining companies.

What if the biggest source of alpha today isn’t stock picking—but structuring portfolios more intelligently after taxes? In this episode, I sit down with Shang to discuss why tax alpha is becoming one of the most important themes in wealth and asset management. Shang breaks down how long-short tax-aware strategies work, why manager selection matters more than most investors realize, and how investors should think about tracking error, leverage, and operational risk. We also explore portable alpha, hedge fund tax structures, and why the explosion of tax-focused products may create as many risks as opportunities.

What if the best opportunities in venture today aren’t in new deals—but in existing companies right before an inflection point? In this episode, I sit down with Ryan Moore, Founder of Revenant VC and longtime venture investor, to discuss why he made the shift from primary venture investing to secondaries after more than two decades in the industry. Ryan explains how longer liquidity timelines are reshaping venture capital, why secondary investing is less about discounts and more about information asymmetry, and how founder relationships and insider alignment create the best opportunities. We also explore organizational metabolism, LP evolution, and why small, focused funds may outperform in a world dominated by mega-platforms.

The biggest edge in private equity is finding deals by going where others won't. In this episode, I sit down with Oscar Fahlgren, Chief Investment Officer of Mubadala Capital, to discuss how embracing complexity and scale creates asymmetric opportunities in global private markets. Oscar explains why large, complex deals often have less competition, how Mubadala Capital uses its balance sheet to anchor and syndicate multi-billion dollar investments, and why partnership—not control—is central to their strategy. We also explore the fallacy of short-term DPI, the rise of GP partnerships, and how long-term capital and alignment drive better outcomes across cycles.

What if the highest-return investments are the ones that reshape the future—not just the ones that fit today’s market? In this episode, I sit down with L.R. Fox, Managing Director of NEXT Global Capital, to discuss why he rejected the traditional path of “build wealth first, give later” and instead built a strategy around impact from day one. Fox explains why capital is a vote for the future, how the best investments often sit outside crowded sectors, and why frontier technologies with real-world impact can outperform conventional venture. We also explore his “buy, build, invest” framework, how he creates entirely new markets, and why resilience—not IQ—is the strongest predictor of success.

What if the best investments aren’t the riskiest—but the ones everyone else can’t own? In this episode, I sit down with Keri Findley, Founder and CEO of Tacora Capital, to discuss how she built one of the most differentiated credit strategies by focusing on illiquidity, not risk. Keri explains how dislocations are often driven by forced sellers and structural constraints, why the best credit opportunities come from creating assets rather than just finding them, and how she partners with startups to finance products banks won’t touch. We also explore portfolio construction, why scaling is the hardest problem in credit, and how incentives, ethics, and alignment ultimately determine outcomes.
