CHTR vs CMCSA: 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.

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; Cox combination 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; losses widened to about 172,000 in the second quarter of 2026. For CMCSA, comcast's core video business is in secular decline as cord-cutting erodes traditional cable-TV subscribers, and broadband subscribers keep shrinking under heavy competition from fiber overbuilders (AT and T, others), fixed-wireless from T-Mobile and Verizon, and newer satellite mobile and internet offers.

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 near 3 times trailing earnings, one of the lowest multiples among large US companies, because the market expects broadband declines to continue and because roughly $97 billion of debt sits beneath a $14.6 billion equity value, so small changes in EBITDA swing the stock. Q2 2026 EPS of $10.66 beat estimates even as revenue fell 1.7% and broadband losses widened. Third-quarter results arrive November 6, 2026, with consensus EPS around $9 and revenue near $14.9 billion including Cox.

CMCSA. At roughly six to seven times earnings and a ~6% yield, Comcast is priced for continued decline in its core broadband business, which shrank its market value to under ~$80 billion in October 2026. The bull case rests on ~$12.7 billion of trailing free cash flow, parks and Peacock growth, and the pricing reset stabilising subscribers; the bear case is that lower ARPU and free lines compress margins faster than retention improves. Third-quarter results on 22 October 2026 (consensus ~$0.99 EPS) are the next read.

Headline figures (approximate, October 2026): CHTR shows revenue (ttm) ~$54.4B; Q2 2026 ~$13.5B, down ~1.7% YoY, net income (ttm) ~$4.9B (~9% net margin), eps (q2 2026) $10.66 vs ~$10.06 consensus, p/e (trailing / forward) ~2.9x / ~2.4x; CMCSA shows revenue (ttm) ~$124.9 billion; Q2 2026 ~$29.94 billion, -~1.2% y/y, operating margin ~17% latest; ~14.7% trailing per Trefis, down from ~18.1%, net income (ttm) ~$11.2 billion (~$3.10 EPS), p/e trailing / forward ~7.2x / ~6.2x.

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.
