ARCC vs BXSL: 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.

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. ARCC and BXSL 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 ARCC and BXSL 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.

Ares Capital Corporation is a business development company (BDC), a listed vehicle that lends directly to middle-market US businesses, companies typically too small for public bond markets but too large for a local bank. It is the largest BDC by market value and is externally managed by an affiliate of Ares Management, one of the world's biggest alternative-credit managers, which gives it a deep origination platform and sponsor relationships. As of March 31, 2026 its portfolio investments totaled roughly $29.5 billion and net asset value was about $19.59 per share. New commitments in early 2026 skewed heavily to first-lien senior secured loans (around 56%), with the vast majority of the portfolio in floating-rate debt, so income tends to rise and fall with short-term interest rates.

Blackstone Secured Lending Fund is a specialty finance company, structured as a BDC under the Investment Company Act of 1940 and externally managed by Blackstone Private Credit Strategies LLC, an affiliate of Blackstone Inc. Its business is direct lending: originating and holding loans to private, mostly sponsor-backed US companies that are too large for a bank branch and too private for the bond market. As of June 30, 2026, roughly 96.8% of the portfolio sat in first-lien senior secured debt, about 96.3% of investments carried floating rates, and exposure was spread across 313 borrowers in 39 industries with no single issuer above 3%. Weighted average borrower EBITDA was around $221 million and average loan-to-value was ~51.9%, which is the arithmetic behind the fund's claim that it lends high in the capital structure to companies of real size.

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

• ARCC drivers: Scale and the Ares platform; Floating-rate income and interest rates.
• BXSL drivers: A senior-secured, floating-rate loan book; Blackstone's origination machine.

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: The central risk is credit quality: ARCC lends to leveraged private companies, so an economic slowdown can raise defaults and non-accruals, erode net asset value, and pressure the dividend. For BXSL, credit risk is concentrated in private, sponsor-backed borrowers whose financials are not publicly reported and whose valuations are determined quarterly by the Board of Trustees with a third-party valuation firm rather than by a market price, so marks can move sharply when spreads widen.

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 ARCC if you believe its drivers more; BXSL 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 ARCC and BXSL guides.

ARCC. Figures are approximate and tied to the asOf date; verify live numbers before acting. Unlike an operating company, a BDC is best judged on net asset value per share, whether the dividend is covered by net investment income, and the level of non-accruals, rather than on a traditional earnings multiple. A yield in the double digits reflects both the income design of the structure and the credit risk of lending to leveraged private companies, so a high headline yield is not automatically a bargain.

BXSL. At roughly $24.31 against a ~$25.53 book value, BXSL changes hands near 0.95x NAV, a narrower discount than most listed BDCs carry. Headline P/E of ~19x is misleading for this structure because trailing GAAP earnings of ~$1.27 per share include unrealised markdowns; measured against net investment income of ~$3.14, the same price is closer to 7.7x. Dividend coverage of 97% in the June quarter is the number to watch, since it is the first sub-100% reading in the three years of history the fund publishes.

ARCC and BXSL 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 ARCC and BXSL exposure against your real portfolio. It is not an investment adviser.
