SBIR/STTR 2026: Key Pre-Releases, Open Solicitations & What Comes Next

The 2026 federal funding landscape is already taking shape — and for companies working in deep tech, health, defense, and advanced industries, timing will be critical.

Across agencies like Advanced Research Projects Agency for Health (ARPA-H), Department of Defense, and NASA, a new wave of SBIR/STTR solicitations is either open or about to launch.

Understanding these timelines early is not just useful — it’s strategic.


A Snapshot of What’s Open Now

Several major opportunities are already active or entering key stages:

🏥 ARPA-H

ARPA-H continues to move forward with ambitious health-focused innovation programs.

  • Feedback/questions deadline: May 6, 2026
  • Proposer Day: June 11, 2026
  • Solution Summary deadline: July 10, 2026

These programs are designed for high-impact, transformative technologies — with a strong emphasis on real-world application.


🪖 Department of Defense (DoD)

The DoD has laid out a structured, multi-release calendar extending through October 2026.

  • Rolling pre-releases and openings from April to September
  • Continuous submission windows across multiple cycles
  • Opportunities across Army, Air Force, DARPA, and Navy

This cadence allows companies to plan ahead — but also increases competition, making early positioning essential.


🚀 NASA

NASA is currently running both Phase II and upcoming SBIR/STTR calls:

  • 2025 SBIR Phase II: Open until May 15, 2026
  • 2026–2027 SBIR/STTR calls: Open until May 21, 2026

For companies already in the ecosystem, this is a key moment to secure follow-on funding and advance commercialization.


🔜 What’s Coming Next

Several additional agencies are preparing to release new solicitations:

⚕️ National Institutes of Health (NIH)

Expected opening: Early June 2026
Deadline: September 5, 2026

🚧 Department of Transportation (DOT)

Expected timeline: June–July 2026

🥩 U.S. Department of Agriculture (USDA)

Expected: Phase II in summer, Phase I in fall


The Strategic TakeawaY

2026 is shaping up to be a highly active year for non-dilutive funding across multiple sectors.

But the increase in opportunities comes with:

  • More competition
  • Greater scrutiny
  • Higher expectations around commercialization and impact

Companies that succeed won’t just have strong technology — they’ll have a clear funding strategy aligned with the right pathway.
