In 2026, federal contracting will move away from set-aside-driven, agency-specific vehicles and toward commercial solutions, GWAC usage, OTAs/CSOs, and portfolio-based acquisition led by capability needs rather than programs.
A series of Executive Orders (EOs), a major FAR rewrite, and Department of War acquisition reform are reshaping how the government buys products and services. Contractors who continue operating under the 2020-2024 playbook will find themselves misaligned with how agencies are instructed to buy in 2026.
Executive Orders Driving the Shift
- EO 14271 Commercial First: Prioritizes commercially available products over customized government builds.
- EO 14275 Common Sense Procurement: Directs substantial FAR revision.
- EO 14240 Consolidation Under GSA: Favors GWACs and reduces agency contract duplication.
- EO 14265 Modernizing Defense Acquisitions: Accelerates use of OTAs, prototyping, and non-traditional acquisition.
Implication: Agencies are being told to buy commercially, buy faster, and buy through fewer contract vehicles.
FAR Rewrite: What Changes for Contractors
The FAR overhaul (target completion FY2026) emphasizes:
- Commercial solutions and best value
There is a heavy focus on leaning into commercial solutions and “best value.” The goal is to align with commercial standards and practices. - Greater use of OTAs and CSOs
Commercial-first complements the growing use of flexible methods like OTAs and Commercial Solutions Openings (CSOs), which enable rapid iteration on concepts or the acquisition of existing commercial offerings. - Preference for GWACs over Agency MAC IDIQs
The FAR revision reinforces the use of GWACs as highly desirable over agency-specific multiple-award IDIQs. We have long had a proliferation of contract vehicles that are arguably redundant, and this helps curb that trend. - Phased procurements to reduce industry burden
This allows the government to reduce competition in a sensible manner, and industry to know when they are not in a position realistic for an award. - Reduced emphasis on mandatory small business set-asides
Agencies may still use set-asides, but the emphasis placed on set-asides is greatly reduced.
The “Rule of Two” remains, but its practical influence is diminishing.
If you rely heavily on:
- 8(a) sole source
- Small business set-asides
- Agency MAC IDIQ positions
You must reassess your strategy now.
GWACs Rising, Agency MACs Declining
Executive direction is clear: reduce redundant vehicles.
Examples already affected:
- DHS PACTS III
- FirstSource III
- DAFSTS II
- Delays in RS3 / ITES-3S transition to MAPS
Expectation: Many agency IDIQs will quietly retire at recompete and be replaced by GSA MAS or GWAC usage, such as OASIS+.
DoW Reorganization: PEOs Becoming PAEs
The Department of War is shifting from program-centric to capability portfolio acquisition. This is driven by the announced changes in November 2025 and EO 14265.
- PEOs become Portfolio Acquisition Executives (PAEs)
This works to organize personnel and plans by capability vs. platform/program. - Contracting Officers aligned to portfolios
The new structure involves KOs (Contracting Officers) aligned with PAEs. - 4+ year assignments for continuity
Long-term assignments for PAE personnel ensure consistency. - Focus on rapid iteration and prototyping
Acquisition processes are moving away from multi-phased systems. This is consistent with a more commercial focus on “fail fast” rather than traditional acquisition methods. - AI-assisted acquisition planning
Speed is prioritized, and there is an intent to embrace AI enablers to review program strategies and plans to accelerate approvals.
Implication: Contractors must align to capability outcomes, not programs.
The Rise of the “NEO Prime”
A new class of contractor is naturally aligned to this changed environment. The emphasis on rapid iteration and commercial products is fueling the prominence of NEO primes. What is a NEO prime? These are businesses that operate with a fundamentally different mindset than traditional government contractors.
These firms:
- Build commercial products first and then bring them to market
- Align with newer government goals emphasized on speed
- Deliver “good enough” solutions fast
- Have a higher threshold to accept risk
- Are better positioned to use OTAs and CSOs
Examples include:
- Anduril (autonomous systems, Lattice AI)
- Palantir (data platforms, embedded engineering)
- SpaceX (launch, Starlink)
This is the model agencies are being encouraged to emulate.
Golden Dome (GD4A): The Largest Signal of What’s Coming
Golden Dome is not just a program. It is a blueprint for future acquisition. GD4A is set to drive significant spending and shape the future of defense contracting in 2026. This multi-year program represents an effort to protect against rapidly evolving threats from ballistic missiles, advanced cruise missiles, hypersonic weapons, and drones. This is driven by the SHIELD IDIQ (in part, but not entirely) and an emphasis on rapid capability development and modernized acquisition approaches.
- FY2026 funding: $23B
- Lifetime estimates: up to $3.6T (depends on the source)
- Emphasis on:
- Use of autonomous weapons
- Hypersonic defense
- Low-cost interceptors
- Cyber and EW
- Modular design
- AI decision aids
- Rapid test & evaluation
Task orders on SHIELD (see below) are expected in Q2 FY2026.
SHIELD IDIQ: $151B Spending Pathway
While MDA executed the initial SHIELD IDIQ awards (see below), the GD4A opportunity is far broader than serving MDA alone. This includes organizations such as the U.S. Space Force’s Space Systems Command (SSC) and the Space Development Agency (SDA). We cannot forget others, such as the U.S. Army’s Space and Missile Defense Command (SMDC).
- Over 2,400 awards already made.
- 12-month off-ramp if awardees submit zero compliant proposals.
- SHIELD is a major path into Golden Dome work, but not the only one.
Who This Impacts Most
Small businesses reliant on set-asides: Your moat is shrinking.
Holders of Agency MAC IDIQs: Your vehicle may not survive recompete.
Traditional primes building to spec: You are misaligned with “Commercial First.”
Firms pursuing DoW and space/missile defense work: You must understand Golden Dome and SHIELD now.
What Contractors Should Do in 2025
- Assess exposure to set-aside dependence
- Position on GWACs and GSA MAS
- Develop commercial-first offerings
- Learn OTAs and CSOs
- Align messaging to capability outcomes
- Build Golden Dome value propositions now
Bottom Line
Federal procurement in 2026 will reward companies that:
- Sell commercial solutions
- Operate outside traditional FAR constraints
- Align to capabilities, not programs
- Use GWACs, OTAs, and CSOs effectively
- Move at commercial speed
This is not a gradual shift. It is structural.
Takeaway: This is a major pathway to pursue GD4A opportunities, but it is far from the only one. Are you curious to know what else is there? Contact us.
