DNA vs MRNA: 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. DNA and MRNA 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 DNA and MRNA 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.

Ginkgo Bioworks Holdings, Inc. (NYSE: DNA) is a synthetic-biology company built around a horizontal cell-programming platform. Historically it reported in two segments: Cell Engineering, where its automated Foundry labs and Datapoints data service engineer and characterize cells for pharma, agriculture, food, and industrial customers; and Biosecurity, which provided pathogen monitoring and bioinformatics to governments and institutions. Cell Engineering revenue is generated through R&D service fees, its Datapoints biological-data offerings, and design, build, and support fees for its lab-automation (RAC) systems. Ginkgo went public via SPAC in 2021 at a lofty valuation that has since collapsed.

Moderna is a Cambridge, Massachusetts biotechnology company built entirely around messenger RNA (mRNA) technology, the platform behind its Spikevax COVID-19 vaccine. After generating enormous pandemic-era revenue, demand has fallen sharply, and the company is trying to broaden beyond COVID into a wider vaccine and therapeutics franchise. Its approved and near-market products include Spikevax, the mRESVIA RSV vaccine for older adults, and newer respiratory approvals in Europe (mNEXSPIKE and the mCOMBRIAX combination shot), while its most watched late-stage assets are the mRNA-1010 seasonal flu vaccine and intismeran autogene (mRNA-4157), a personalized cancer vaccine developed with Merck.

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

• DNA drivers: AI, autonomous labs, and Datapoints; Cost restructuring toward breakeven.
• MRNA drivers: Respiratory franchise beyond COVID; Oncology optionality via Merck partnership.

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 dominant risk is cash burn against an uncertain path to profitability: Ginkgo remains deeply unprofitable, revenue has kept falling year over year, and it is spending down its cash while promising breakeven that has not yet arrived. For MRNA, revenue has fallen dramatically from pandemic highs and COVID demand remains uncertain, so the current business does not cover operating costs.

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 DNA if you believe its drivers more; MRNA 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 DNA and MRNA guides.

DNA. These are qualitative descriptions, not precise figures, and they are tied to the asOf date; verify live numbers before acting. Traditional earnings multiples do not apply to Ginkgo because it is unprofitable, so what matters is the trajectory of revenue, losses, cash burn, and progress toward the stated breakeven target. Because the company is pre-profit and pivoting its model, its valuation reflects belief in a future that has not yet been proven.

MRNA. MRNA trades on pipeline potential rather than current earnings, since it is loss-making with revenue far below its pandemic peak. Traditional multiples like P/E are not meaningful while the company is unprofitable, so the market is effectively pricing the odds of flu, combination, and cancer-vaccine programs succeeding. The multibillion-dollar cash balance is a key reason the company can fund that pipeline toward its 2028 break-even goal.

Headline figures (approximate, Jul 2026): DNA shows revenue (ttm) Small and declining; Cell Engineering revenue fell year over year, and recent quarterly revenue dropped sharply versus the prior-year period, net loss / adjusted ebitda Still loss-making; large GAAP net losses continue, though narrower than before, with adjusted-EBITDA breakeven targeted by end of 2026, cash position Several hundred million dollars in cash and marketable securities, funding operations while the company burns cash under its restructuring plan, path to profitability Management guides to adjusted-EBITDA breakeven by the end of 2026 via cost cuts; sustained GAAP profitability is not yet in sight; MRNA shows market cap ~$20 billion, q1 2026 revenue ~$400 million, q1 2026 net loss ~$1.3 billion (incl. ~$878M legal charge), 2026 revenue growth guidance up to ~10%.

DNA and MRNA 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 DNA and MRNA exposure against your real portfolio. It is not an investment adviser.
