CDLX vs V: 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. CDLX and V 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 CDLX and V 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.

Cardlytics, Inc. operates what it calls a purchase intelligence platform: an advertising network that runs inside the online and mobile banking channels of its financial institution (FI) partners. Banks share anonymized transaction data with Cardlytics, which uses it to target offers (for example, 10% back at a restaurant chain) to the bank's own customers. Most campaigns are priced on a Cost per Served Sale basis, a percentage of all purchases made by consumers who were shown the offer. Revenue is reported net of the cash-back paid to consumers and gross of the Partner Share paid to banks, which is why the company also reports billings, the gross amount charged to marketers. Named FI partners include Chase, Wells Fargo and American Express, plus regional banks, fintechs and digital banks.

Visa operates the world's largest electronic payments network, connecting banks, merchants, and cardholders so that card transactions clear and settle in seconds across more than 200 countries. Critically, Visa does not lend money or issue cards itself: banks issue Visa-branded credit and debit cards and take the credit risk, while Visa runs the rails (VisaNet) that authorize, clear, and settle the transactions. Visa earns a small fee on the gross dollar value of payments and on the number of transactions processed, so revenue scales with global consumer and commercial spending. This is an exceptionally high-margin, asset-light toll-booth model: more spending and more transactions flow through the same network. Visa also offers value-added services (fraud, data, advisory, tokenization) and is expanding into new payment flows like business-to-business, person-to-person, and government disbursements. Headquartered in San Francisco, Visa is one of the most profitable large-cap companies in the world.

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

• CDLX drivers: Stabilizing billings after the bank partner loss; Margin per dollar of revenue.
• V drivers: Secular shift from cash to digital; Network effect and toll-booth economics.

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 the capital structure: at roughly $12 million of market value, the equity is small next to $172.5 million of convertible notes due April 2029 and a $15.0 million credit line, and stockholders' equity was already a $16.0 million deficit at June 30, 2026, so a refinancing or exchange could heavily dilute or largely wipe out existing shareholders. For V, visa's spending-linked revenue makes it cyclical: a recession that cuts consumer and cross-border spending directly slows growth, and high-margin cross-border travel volume is especially economically sensitive.

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 CDLX if you believe its drivers more; V 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 CDLX and V guides.

CDLX. Trailing revenue of ~$169 million against a market value of roughly $12 million (about 5.8 million shares near $2) puts the stock at well under 0.1x sales, a level that reflects the debt more than the size of the business. Adding the convertible notes and credit line and subtracting cash gives an enterprise value near ~$160 million, about 1x revenue. Billings run ~$297 million over twelve months; revenue is lower because cash-back paid to consumers is netted out. Adjusted EBITDA is near break-even while free cash flow is negative, and Q3 2026 guidance calls for $34 million to $39 million of revenue.

V. Visa trades at a premium multiple that reflects its exceptional margins, asset-light model, durable cash-to-digital tailwind, and prodigious free cash flow. The valuation embeds high expectations for sustained mid-to-high-single-digit volume growth. Visa is widely viewed as a quality compounder, and the multiple has historically compressed only during severe spending downturns or regulatory shocks.

Headline figures (approximate, October 2026): CDLX shows revenue (ttm, continuing ops) ~$169M, billings (ttm) ~$297M, q2 2026 revenue $36.9M (-36% YoY), adjusted ebitda (h1 2026) ~$1.9M; V shows revenue (ttm) ~$38 billion, operating margin ~65-67% (among the highest in the S&P 500), net income (ttm) ~$20 billion, eps (ttm) ~$10 adjusted.

CDLX and V 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 CDLX and V exposure against your real portfolio. It is not an investment adviser.
