ARCC vs GBDC: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of October 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 GBDC 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 GBDC 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.

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.

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.
• GBDC drivers: High distribution, thin coverage; First-lien, sponsor-backed book.

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 GBDC, gBDC is a leveraged lender to private middle-market borrowers, so a recession or rising defaults could push non-accruals higher and erode NAV; the March 2026 quarter's GAAP net loss of about $47 million came largely from unrealized markdowns.

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; GBDC 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 GBDC guides.

ARCC. For a BDC, price-to-NAV, dividend coverage and non-accruals matter more than a P/E. At ~0.98x book, ARCC trades near net asset value rather than at the premium it often carried, and the ~10.2% yield reflects a payout that core earnings have slightly trailed in 2026. Third-quarter results on October 27, 2026 (consensus core EPS ~$0.48) will show whether coverage returns to the full dividend.

GBDC. At $12.26, GBDC trades at about 0.86x book and roughly 9.7x forward earnings, with a distribution yield near 10.8%. The June 2026 quarter met the $0.33 estimate on revenue of about $188 million, but income is down about 14% from a year earlier and adjusted EPS now exactly covers the distribution. Fiscal Q4 results are due November 17, 2026, with consensus at $0.33.

Headline figures (approximate, October 2026): ARCC shows total investment income (ttm) ~$3.11 billion; Q2 2026 ~$768 million, up ~3% year over year, core eps $0.47 in Q1 and Q2 2026 vs $0.48 and $0.47 estimates, gaap net income (ttm) ~$960 million; Q2 2026 ~$171 million, quarterly dividend $0.48 per share ($1.92 annual rate); GBDC shows total investment income (ttm) ~$801M, revenue growth (latest quarter, yoy) ~-14%, adjusted eps (june 2026 qtr vs estimate) $0.33 vs $0.33, gaap net income (ttm) ~$172M.

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