BX vs RPRX: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: RPRX is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

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. BX and RPRX 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 BX and RPRX 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.

Blackstone Inc. is the world's largest alternative asset manager, investing on behalf of pension funds, sovereign wealth funds, insurers, endowments, and increasingly individual investors. It runs money across several major strategies: real estate (historically its largest), private equity, credit and insurance, infrastructure, life sciences, growth equity, secondaries, and hedge fund solutions. The business model has two engines. First, it earns recurring management fees on the capital it manages, which produces relatively stable fee-related earnings and grows as assets under management climb. Second, it earns performance fees (carried interest and incentive fees) when its funds generate strong returns, which are lumpier and depend on realizations and market conditions. Because most of its capital is locked up in long-dated funds, Blackstone has durable, contracted fee streams, and it distributes a large share of its distributable earnings to shareholders as a variable quarterly dividend rather than a fixed one.

Royalty Pharma plc buys the right to receive royalties on approved and development-stage biopharmaceutical products. A university, a research hospital, a small-cap biotech or a large pharmaceutical company owns a royalty on a drug; Royalty Pharma pays a lump sum, sometimes staged across milestones, and thereafter receives a percentage of that drug's top-line sales. The portfolio spans more than 35 marketed therapies and 19 development-stage candidates. In the second quarter of 2026 the largest contributors were Vertex's cystic fibrosis franchise at $194 million of Royalty Receipts, Biogen's Tysabri at $67 million, GSK's Trelegy at $58 million, Johnson & Johnson's Tremfya at $57 million, Roche's Evrysdi at $47 million and Servier's Voranigo at $46 million. Founded in 1996 and public since 2020, the company is incorporated in England and Wales, headquartered in New York, and lists only its Class A ordinary shares on Nasdaq. Until May 16, 2025 it was externally managed and paid a quarterly fee of 6.5% of royalty cash receipts plus 0.25% of security investments; that manager was bought in, and the staff now sit inside the company.

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

• BX drivers: Growth of assets under management; Private wealth and retail channel.
• RPRX drivers: Royalty Receipts are outrunning the headline receipts number; The internalisation permanently changed the cost line.

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: Blackstone's risks stem from its market-linked, cyclical model. For RPRX, concentration is the first thing to size.

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 BX if you believe its drivers more; RPRX 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 BX and RPRX guides.

BX. These figures are qualitative and approximate as of the asOf date, not precise real-time numbers. Because performance fees and the variable dividend move with realizations and markets, quarterly results can be uneven. Confirm live AUM, revenue, fee-related earnings, dividend, and valuation before acting.

RPRX. The ~14 times sales a screener prints comes from dividing a $35.25 billion market cap by $2.54 billion of GAAP revenue, which is the wrong denominator for this structure. Measured against the $3.4 billion to $3.5 billion of Portfolio Receipts guided for 2026, the same market cap is about 10 times, and enterprise value is roughly 13.5 times trailing Adjusted EBITDA. The gap between the trailing P/E near 33 and a forward P/E near 11 is the same effect seen from the earnings side, with non-cash provisions and impairments compressing reported profit while cash collections keep rising.

Headline figures (approximate, Jul 2026): BX shows assets under management More than $1.3 trillion as of early 2026, the largest of any alternative asset manager, after record inflows (roughly $70 billion in a recent quarter), revenue trend Full-year 2025 revenue was about $14.5 billion, up roughly $1.2 billion year over year; management and advisory fees were about $8.1 billion, profitability Emphasizes fee-related earnings (recurring management fees) as the stable core, with performance fees (carried interest) adding lumpier upside tied to realizations, capital returns Pays a variable quarterly dividend tied to distributable earnings (not a fixed rate) plus buybacks, so the payout rises and falls with results; RPRX shows revenue (ttm, gaap) ~$2.54 billion of total income and other revenues for the twelve months to June 30, 2026, against $2,378 million in fiscal 2025, $2,264 million in 2024 and $2,355 million in 2023. GAAP quarterly income was $674 million in the second quarter of 2026, of which $638 million was income from financial royalty assets and $36 million other royalty income. The line is not a sales figure in the ordinary sense: it is the interest component of royalty collections, accreted under the effective interest method off sell-side consensus sales forecasts, so it moves when analysts revise the drugs Royalty Pharma has bought into., portfolio receipts (the operating measure) $3,254 million in 2025, up 16% from $2,801 million in 2024, and $1,698 million in the first half of 2026, up 8.4% from $1,566.8 million. Royalty Receipts, the sales-linked core, were $3,127 million in 2025 and $1,655 million in the first half of 2026 (up 13.4%). Guidance raised on August 5, 2026 puts full-year Portfolio Receipts at $3,400 million to $3,500 million, with Royalty Receipts growth of 7% to 10% and an assumed ~1% currency tailwind, excluding anything transacted after that date., earnings and eps Diluted EPS of $1.86 on a trailing twelve-month basis, from net income attributable to Royalty Pharma plc; GAAP net income was $770.95 million in fiscal 2025 and $858.98 million in 2024. The quarterly path is erratic by design: first-half 2026 diluted EPS was $0.71 on $312.6 million attributable to the plc, but the second quarter alone was $0.04 after a $268 million provision for changes in expected cash flows. Consolidated net income of $549.7 million in the half was reduced by $237.2 million attributable to non-controlling interests before reaching Class A holders., cash flow and adjusted ebitda Net cash provided by operating activities was $1,447 million in the first half of 2026 against $960 million a year earlier, and $2,490 million for full-year 2025. Adjusted EBITDA, defined in the credit agreement as Portfolio Receipts less payments for operating and professional costs, was $736 million in the second quarter and roughly $3.2 billion trailing; Portfolio Cash Flow, after net interest, was $736 million in the quarter and $2,724 million in 2025. Payments for operating and professional costs ran at 4.8% of Portfolio Receipts in the quarter versus 8.9% for all of 2025..

BX and RPRX 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 BX and RPRX exposure against your real portfolio. It is not an investment adviser.
