The CLIMB Act bars federal agencies from taking adverse action against any person solely because that person provides business assistance to a cannabis‑related legitimate business, with a broad catalog of covered activities from lending and insurance to legal, accounting, real estate, and underwriting. It also amends Section 6 of the Securities Exchange Act of 1934 to add a safe harbor that explicitly permits national securities exchanges and market participants to list, trade, and facilitate offerings of securities issued by cannabis‑related legitimate businesses and certain service providers, notwithstanding the Controlled Substances Act or other federal law.
Why it matters: the bill removes two major federal-level frictions that have kept state‑legal cannabis businesses largely excluded from mainstream capital markets and from routine financial services. If implemented as written, exchanges could actively list state‑legal cannabis issuers and a wider array of vendors and financial firms could provide services with reduced risk of being penalized solely for that business relationship, creating new capital and operational options for the industry — while raising complex questions about enforcement, disclosure, and anti‑money‑laundering compliance.
At a Glance
What It Does
The bill prohibits federal agencies from imposing adverse actions solely for providing specified business assistance to state‑legal cannabis businesses, and it adds a new subsection to Exchange Act §6 that creates a statutory safe harbor allowing national exchanges and market participants to list and trade securities of cannabis‑related legitimate businesses and certain non‑cannabis service providers.
Who It Affects
National securities exchanges, brokers, dealers, underwriters, clearing agencies, and other market participants; banks, insurers, real‑estate lessors, accountants, lawyers, and technology vendors who serve state‑legal cannabis companies; and the issuers themselves and their investors.
Why It Matters
The bill removes a concrete federal legal barrier that has deterred mainstream capital markets and many financial services firms from engaging with the cannabis sector, potentially unlocking public listings and broader financial access while forcing market infrastructure and regulators to confront new compliance and disclosure questions.

What This Bill Actually Does
The CLIMB Act has two parallel tracks: first, it tells federal agencies they may not take adverse actions against a person solely because that person provides business assistance to a cannabis‑related legitimate business. The statute lists many activities that count as business assistance — from loans, insurance, and equity investments to accounting, real‑estate leasing, advertising, IT services, and underwriting — and defines 'person' broadly to include individuals and nearly every type of business entity.
The limitation is framed as a prohibition on agency conduct when the action is based only on the provision of those services.
Second, the Act inserts a new subsection into Section 6 of the Securities Exchange Act that creates a safe harbor for national exchanges and market participants. The new text defines 'cannabis' and 'cannabis‑related legitimate business,' identifies what counts as a 'service provider,' and then states that it is not unlawful for a registered national exchange or market participant to list, permit trading of, or otherwise facilitate offerings of securities of those issuers — explicitly overriding section 32 of the Exchange Act, the Controlled Substances Act, and other federal laws for these specific activities.Taken together, the two tracks aim to de‑risk both the provision of ordinary business services to state‑legal cannabis enterprises and the participation of securities markets in supporting those enterprises.
The bill does not reclassify cannabis under the Controlled Substances Act; rather, it carves out specific protections so that exchanges and service providers are not automatically exposed to federal illegality claims solely because of the underlying business relationship. The Act becomes effective 180 days after enactment, giving market participants and regulators a short runway to prepare policies, listing standards, and compliance procedures.Operationally, the statute leaves several practical choices to exchanges, market participants, and regulators.
Exchanges would still set listing standards and the SEC would retain supervisory authority over securities offerings and market conduct; the safe harbor removes a subset of legal exposure but does not eliminate securities regulation, disclosure obligations, or routine enforcement based on fraud, false statements, or other traditional securities violations. Meanwhile, the prohibition on adverse agency actions is narrowly framed: agencies cannot act 'solely because' a person provides assistance, but they can take action when additional grounds exist.
That textual limitation will determine how widely the protection is applied in practice.
The Five Things You Need to Know
The bill bars any Federal agency from taking an 'adverse action' against a person solely because that person provides business assistance to a cannabis‑related legitimate business; covered assistance is explicitly listed and broad.
It amends Exchange Act §6 by adding subsection (m) that defines 'cannabis‑related legitimate business' and 'service provider' and states it is not unlawful for national exchanges or market participants to list, trade, or facilitate securities of those entities, notwithstanding the Controlled Substances Act or Exchange Act §32.
The definition of 'business assistance' (Sec. 2) and the Exchange Act's 'service provider' (Sec. 3(m)) both include underwriting, placement, and public distribution services — meaning securities firms and exchanges are expressly covered when facilitating offerings.
The Act does not change cannabis’s status under the Controlled Substances Act; instead it creates statutory protections for certain market and service activities while leaving other federal laws and securities‑fraud rules intact.
The bill takes effect 180 days after enactment, providing a limited implementation window for exchanges, market participants, banks, and regulators to adapt listing rules and compliance frameworks.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
This is the technical naming provision — the 'Capital Lending and Investment for Marijuana Businesses Act' or 'CLIMB Act.' Its practical effect is purely stylistic and does not alter any substantive authority or create administrative obligations.
Prohibits agency adverse actions based solely on providing business assistance
This is the operational heart of the bill for non‑market actors. It instructs all federal agencies not to take adverse actions (an undefined term) against any 'person' solely because that person provides enumerated forms of business assistance to a state‑legal cannabis business. The provision lists covered services in detail — from lending, insurance and investments to legal, accounting, IT, real estate, logistics, advertising, and underwriting — and adopts a broad 'person' definition covering virtually any business form. Because the statute limits agency action only where it is taken 'solely' for the assistance, agencies retain the ability to act for any other lawful reason; how courts will interpret 'solely' will determine the provision’s practical reach.
Adds a safe harbor enabling national exchanges and market participants to list and facilitate cannabis-related securities
This amendment inserts a new subsection (m) into Section 6 with definitions and a short, categorical safe harbor. It identifies who qualifies as a 'cannabis‑related legitimate business' and who counts as a 'service provider,' then states that, notwithstanding section 32, the Controlled Substances Act, or any other federal law, it shall not be unlawful for a registered national exchange or any market participant to list, permit trading of, or facilitate offerings of such securities. The language removes a specific legal obstacle for exchanges and securities firms but does not absolve issuers or intermediaries of standard securities laws like antifraud provisions, disclosure duties, or SEC oversight — those regimes remain operative.
Effective date
All provisions become effective 180 days after enactment. That delay creates a short implementation period during which exchanges, broker‑dealers, banks, and regulators would need to update policies, SRO rules, listing applications, and AML/compliance procedures before the statutory protections take effect.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- National securities exchanges and market participants — the safe harbor reduces federal‑law exposure for listing and trading securities of state‑legal cannabis issuers and related service providers, allowing exchanges to consider listing such issuers without automatic CSA‑based legal risk.
- Cannabis-related legitimate businesses and their investors — clearer access to public capital markets and to underwriters, potentially lowering the cost of capital and increasing liquidity for state‑legal operators.
- Banks, insurers, and other financial service providers — the prohibition on adverse agency actions narrows the federal risk of offering loans, deposits, insurance, or other financial products to state‑legal cannabis clients, encouraging broader participation.
- Professional service firms (accountants, lawyers, compliance vendors, real‑estate lessors, IT providers) — reduced chance of federal administrative penalties solely for serving cannabis businesses, which should expand the pool of vendors willing to work in the sector.
- State regulatory systems and marketplaces — by enabling integration with national capital markets, state‑legal programs may see improved capital inflows and more formalized corporate governance among regulated operators.
Who Bears the Cost
- Federal agencies (enforcement arms) — the statutory restraint narrows their discretionary enforcement options and may require retooling of guidance, investigative priorities, and interagency coordination when cannabis‑related factors are present.
- Exchanges, broker‑dealers, and compliance functions — while the safe harbor reduces a legal barrier, these actors will face new compliance, surveillance, and listing‑standard costs to vet cannabis issuers and their complex state‑by‑state legal footprints.
- Smaller banks and community lenders — potential increased compliance and AML/BSA burden from onboarding cannabis clients may require investments in monitoring systems and staff, raising marginal costs.
- Investors and fiduciaries — public investment in businesses that remain federally illegal creates novel legal risk profiles and potential reputational exposure for institutional investors and retirement plans.
- State and tribal regulators — greater capital inflow and interstate investor interest could raise enforcement and consumer‑protection demands at the state/tribal level, with associated resource strains.
Key Issues
The Core Tension
The central dilemma is whether to prioritize integrating state‑legal cannabis businesses into mainstream finance — improving access to capital, transparency, and vendor services — or to prioritize the integrity of federal drug and anti‑money‑laundering regimes; the bill reduces legal barriers to market participation but stops short of resolving the compliance and enforcement frictions that arise from the continued federal illegality of cannabis.
The bill uses a narrow but consequential drafting technique: agencies cannot take adverse action 'solely because' a person provides business assistance. That preserves agency authority to act when other legal grounds exist (e.g., money‑laundering violations, fraud, sanctions, or criminal conduct), but it invites litigation over what counts as an action taken 'solely' for the assistance.
Absent a statutory definition, agencies and courts will likely need to develop tests to separate protected conduct from actionable misconduct that happens to involve a cannabis customer.
The Exchange Act safe harbor removes a distinct legal barrier by saying it is 'not unlawful' for exchanges and market participants to list and trade securities of state‑legal cannabis issuers and service providers, 'notwithstanding' the Controlled Substances Act or section 32. That language is powerful in theory but narrow in application: it does not de‑schedule or reclassify cannabis, nor does it immunize issuers or intermediaries from the federal securities laws’ antifraud, disclosure, or market‑integrity rules.
Exchanges and the SEC will confront practical questions about listing standards, disclosure of state compliance risks, valuation challenges in an industry barred from interstate commerce in many respects, and how to reconcile AML/BSA obligations with the new protections. Finally, because the bill leaves numerous terms (for example, 'adverse action') undefined and defers operational details to market practice, much of its real‑world effect will be shaped by subsequent litigation, agency guidance, exchange rulemaking, and SRO decisions.
