How would codifying the 'rule of two' in House proposals change small business set-aside opportunities and what should small firms do now? 2026

According to GSA guidelines, contractors must expect a stronger presumption in favor of small-business set-asides if the House proposals codify the 'rule of two.' The change directly affects contracting officers, large prime contractors competing for subcontracts, and certified small businesses (8(a), HUBZone, WOSB, VOSB, SDVOSB). Per FAR 19.502, contracting officers already must perform market research and document determinations when setting aside requirements; codification makes the paperwork and set-aside decision the default rather than an exception. The SBA reports that 78% of agency small-business goaling relies on timely documentation and accurate classification of firms; codification would therefore increase SBA monitoring and reporting activity. Under OMB M-25-21, agencies will be expected to justify cloud and AI acquisitions that affect small business access to procurements, and those justifications will now need to align with a statutory 'rule of two' presumption. DoD's CMMC framework requires cybersecurity vetting for many defense procurements, and small firms should budget the time and dollars to meet CMMC or FedRAMP requirements before they bid. This paragraph explains who must act and why: contracting officers will have less discretion, SBA goaling will tighten, and small firms must improve readiness to capture set-aside awards.
