BEAM vs CRSP: 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. BEAM and CRSP 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 BEAM and CRSP 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.

Beam Therapeutics (NASDAQ: BEAM) develops precision genetic medicines using base editing, a technique it helped invent that rewrites a single letter of DNA without cutting both strands of the double helix, aiming for more precise fixes than first-generation CRISPR. Its pipeline spans risto-cel (formerly BEAM-101) for sickle cell disease, with a biologics license application targeted as early as year-end 2026, plus BEAM-302 for alpha-1 antitrypsin deficiency, and BEAM-301 and BEAM-304 for rare liver-mediated genetic diseases. The company also runs collaborations with partners including Pfizer and Eli Lilly, which supply most of its reported revenue through upfront payments and milestones.

CRISPR Therapeutics AG is a Swiss-American biopharmaceutical company headquartered in Zug, Switzerland, with principal research operations in Boston, Massachusetts. The company uses its proprietary CRISPR/Cas9 platform to develop gene-based medicines across hemoglobinopathies, oncology, cardiovascular disease, autoimmune conditions, and regenerative medicine. Its first and only commercialized product, Casgevy, is co-developed and co-commercialized with Vertex Pharmaceuticals under a 40/60 profit-sharing structure in which CRISPR retains 40 percent of profits. Revenue has historically been driven by collaboration milestone payments from Vertex rather than product sales, making the financial profile highly lumpy. Beyond Casgevy, the company generates no meaningful product revenue today and funds operations through its cash reserves.

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

• BEAM drivers: Risto-cel sickle cell path to filing; In vivo liver franchise.
• CRSP drivers: First-Mover Advantage in Commercial Gene Editing; Casgevy's Long-Term Revenue Potential.

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: Beam is pre-commercial and deeply unprofitable, so it carries the full binary risk of a clinical-stage biotech: a single failed trial, safety signal, or regulatory setback can reset the stock. For CRSP, the commercial ramp of Casgevy has been far slower than early projections: CRSP's reported revenue was only about $3.5 million in all of 2025, down sharply from prior years that were boosted by one-time milestone payments, and only about $13.4 million over the twelve months to June 2026.

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 BEAM if you believe its drivers more; CRSP 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 BEAM and CRSP guides.

BEAM. Beam's revenue is collaboration and milestone income, not product sales, so it is lumpy (about $114 million in the fourth quarter of 2025, zero in the second quarter of 2026) and not comparable to a profitable company's top line. With no approved therapy and heavy R&D spending, the company runs large net losses funded by its cash pile. At about $2.5 billion as of October 16, 2026, the market value is roughly twice the cash balance, so the valuation reflects a modest, probability-weighted view of the pipeline.

CRSP. Because CRISPR Therapeutics has no meaningful product profits yet, traditional earnings-based multiples like P/E are negative and not analytically useful; the company is better evaluated on cash runway, Casgevy adoption, and the risk-adjusted value of its pipeline. Market cap of about $4.9 billion less roughly $1.6 billion of net cash leaves an enterprise value near $3.3 billion, which reflects significant execution uncertainty. Targets remain widely spread, from UBS at $52 to a consensus mean near $86.

Headline figures (approximate, October 2026): BEAM shows market cap ~$2.5B, revenue (ttm, collaboration) ~$156M, revenue (q2 2026) ~$0, net loss (q2 2026) ~$123M; CRSP shows revenue (ttm to jun 30, 2026) ~$13.4 million (Q2 2026 ~$10.2 million), revenue (full year 2025) ~$3.5 million, net loss (ttm) ~$451 million; Q2 2026 ~$91 million, eps (q2 2026, actual vs estimate) -$0.94 vs -$1.18.

BEAM and CRSP 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.
