Opportunities with the Highest Award Ceilings

Individual grant opportunities ranked by maximum award amount — the single largest funding notices posted. Data from USAspending.gov and Grants.gov, covering federal grant awards across all 50 states; see our methodology.

What This Ranking Tells Us

These are the individual funding opportunities (not programs) with the highest possible award amounts. Unlike program-level ceilings, these represent specific notices with deadlines, eligibility requirements, and application instructions. The largest opportunities are typically infrastructure projects, state-formula grants, and major research initiatives. Many require matching funds or cost-sharing, and competition is intense. For most applicants, opportunities in the $100K–$10M range offer better odds of success.

Frequently Asked Questions

What is an award ceiling on an opportunity?

The award ceiling is the maximum amount the agency expects to award to a single successful applicant under this specific funding notice. It differs from the estimated total funding (which covers all awards under the notice) and the award floor (minimum possible award).

Are these opportunities still open?

This ranking includes both open and closed opportunities to show the full scope of federal funding. Check the close date and status on each opportunity's detail page to see if it is still accepting applications.

How competitive are the largest opportunities?

Very competitive. Opportunities with award ceilings above $10M typically attract applications from large universities, state governments, and major nonprofits with dedicated grant-writing teams. Success rates for the largest opportunities are often below 10%.
