CHTR vs CMCSA: 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: CHTR 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. CHTR and CMCSA 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 CHTR and CMCSA 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.

Charter Communications is a leading US broadband connectivity company that markets Internet, Mobile, TV, and Voice services under the Spectrum brand to roughly 59 million homes and businesses across 41 states. The core business is residential and commercial broadband, which throws off large and steady cash flows, while Spectrum Mobile (an MVNO running on Verizon's network) has become the fastest-growing part of the company, reaching about 12.1 million lines as of Q1 2026 after adding around 370,000 lines in the quarter. Traditional cable video continues to shrink as customers cut the cord, so the investment story now centers on defending broadband and converting the base into bundled mobile customers.

Comcast is a global media and technology company built on three main pillars. Its Connectivity and Platforms business, anchored by Xfinity, is one of the largest US broadband and cable providers, selling high-speed internet, video, mobile (Xfinity Mobile), and home services to tens of millions of households, plus business connectivity. Its Content and Experiences business includes NBCUniversal, which owns the NBC broadcast network, cable networks (USA, Bravo, MSNBC, CNBC), the Peacock streaming service, Universal Pictures film studio, and Universal theme parks worldwide. Comcast also owns Sky, a major European media and broadband operator. The company makes money primarily from recurring broadband and connectivity subscriptions, which are its most profitable and stable revenue, supplemented by advertising, content licensing, box-office and streaming revenue, and theme-park admissions. Comcast is headquartered in Philadelphia and generates substantial free cash flow that funds dividends and buybacks.

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

• CHTR drivers: Spectrum Mobile convergence; Pending Cox merger and scale.
• CMCSA drivers: Broadband cash engine; Wireless and convergence.

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: Broadband subscriber losses are the central risk, as fixed wireless from T-Mobile and Verizon (now over 20 million combined FWA subscribers industrywide) and fiber overbuilders continue to take share in a saturated market. For CMCSA, comcast's core video business is in secular decline as cord-cutting erodes traditional cable-TV subscribers, and broadband subscriber growth has stalled or turned negative under heavy competition from fiber overbuilders (AT and T, others) and fixed-wireless from T-Mobile and Verizon.

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 CHTR if you believe its drivers more; CMCSA 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 CHTR and CMCSA guides.

CHTR. Charter trades at a very low single-digit earnings multiple, reflecting the market's concern about broadband subscriber declines and its heavy debt rather than distressed fundamentals. Q1 2026 revenue fell about 1 percent to $13.6 billion and EPS of $9.17 missed estimates, which sent the stock down sharply. The small equity market cap sits atop a much larger enterprise value because of roughly $97 billion in net debt.

CMCSA. Comcast trades at a low earnings multiple relative to the market, reflecting investor concern about cord-cutting, slowing broadband growth, and media disruption. The bull case rests on a high-margin broadband cash engine, growing wireless and theme parks, a solid dividend yield, and aggressive buybacks. The cheap valuation is the market pricing structural decline against still-robust cash generation.

Headline figures (approximate, July 2026): CHTR shows revenue (ttm) ~$54.5B, q1 2026 revenue ~$13.6B (down ~1% YoY), adjusted ebitda (q1 2026) ~$5.64B (down ~2.2% YoY), market cap ~$20B; CMCSA shows revenue (ttm) ~$120 billion, operating margin ~18-20%, net income (ttm) ~$15 billion, dividend yield ~3-3.5%.

CHTR and CMCSA 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 CHTR and CMCSA exposure against your real portfolio. It is not an investment adviser.
