AIO vs PS: Which Is the Better Buy in 2026?

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. AIO and PS share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined AIO and PS exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker. Walnut is not an investment adviser.

The Virtus Artificial Intelligence & Technology Opportunities Fund (AIO) is a closed-end fund, not an operating company. A closed-end fund raises a fixed pool of capital, invests it, and then trades on an exchange like a stock, which means its share price is set by supply and demand and can sit above (a premium) or below (a discount) the net asset value of the securities it holds. AIO is managed by Virtus Investment Advisers and sub-advised by Voya Investment Management, whose team runs a multi-asset strategy focused on companies exposed to artificial intelligence and other disruptive technologies. Rather than holding equities alone, the fund dynamically allocates across a company's capital structure, pairing common stocks with convertible securities that can offer some downside cushion and income.

Pershing Square Inc (NYSE: PS) is the holding company for Pershing Square Capital Management, the New York firm founded by activist investor Bill Ackman. The business earns management fees and performance fees for running a small number of concentrated, long-term equity funds, most visibly the London-listed Pershing Square Holdings (PSH) and the closed-end fund Pershing Square USA (PSUS) that listed on the NYSE in April 2026. As of the end of 2025 the firm managed roughly ~$30.7 billion in total assets with about ~$20.7 billion of fee-paying assets, run by a very small team of around ~44 employees, which gives the model unusually high margins when performance is good.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• AIO drivers: Concentrated AI and technology exposure; Managed monthly distribution policy.
• PS drivers: Growing fee-paying asset base; Performance fees and the Ackman track record.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: AIO carries several fund-specific risks. For PS, pershing Square Inc trades at a very high multiple of current earnings (a trailing P/E near ~170 in mid-2026), so disappointing growth or returns could compress the valuation sharply.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick AIO if you believe its drivers more; PS if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the AIO and PS guides.

AIO. These figures are qualitative and change frequently. The distribution rate is a managed payout, not a yield earned on portfolio income, and it can include a return of capital, so it may overstate the income the underlying holdings generate. Premium and discount to NAV, the distribution rate, leverage, and expenses all move over time. Always verify the live NAV, current discount or premium, and the latest distribution details on the fund's official page or a closed-end fund data source before investing.

PS. Revenue grew sharply into the 2026 listing, but reported GAAP net income over the trailing period was modest relative to the roughly ~$14 billion market value, producing a very high earnings multiple. The valuation reflects expectations for continued growth in fee-paying assets and future performance fees rather than current profit. Figures are approximate and move with fund net asset values and markets.

Headline figures (approximate, Jul 2026): AIO shows distribution rate Pays a managed monthly distribution; the fund raised its monthly payout in mid-2026 and quotes a per-annum rate on both market price and NAV. Treat this as a distribution rate, not a yield on earnings, and confirm the live figure., premium / discount to nav Has generally traded at a discount to net asset value during 2026, though this fluctuates and can move to a premium. Check the current discount before buying., leverage Uses modest leverage (borrowing to invest beyond base assets) to enhance income and return, which magnifies gains and losses and adds interest cost., expense ratio Higher than a typical index ETF, in part because of interest expense on leverage; the ratio is meaningfully lower when borrowing costs are excluded.; PS shows market cap ~$14 billion, revenue (ttm) ~$768 million, net income (ttm) ~$82 million, 2025 revenue ~$762 million.

AIO and PS are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined AIO and PS exposure against your real portfolio. It is not an investment adviser.
