Grand Challenges Grants 2026: Three Open Gates Foundation RFPs and How to Apply
The Gates Foundation Grand Challenges program runs a rolling series of requests for proposals. Three are open right now, with deadlines from July to September 2026 and awards ranging from US$150,000 to US$800,000 per project.
If you have a bold idea that could change how the world tackles disease, malnutrition, or poverty, this is one of the few funding programs that truly wants to hear from you.
The Bill & Melinda Gates Foundation’s Grand Challenges grants are built for big swings, not tiny tweaks. They back early-stage, high-risk concepts that most traditional funders would nervously sidestep.
One thing to understand before you start writing: Grand Challenges is not a single annual competition with one deadline. It is a rolling series of requests for proposals (RFPs). Individual challenges open and close on their own schedules, each with its own topic, eligibility rules, award ceiling, grant term, and closing date. There is no universal “Grand Challenges application.” You apply to one named RFP, on that RFP’s terms.
As of July 28, 2026, the official grant opportunities page lists three challenges with applications open — and their deadlines are spread across six weeks.
The Three RFPs Open Right Now
1. Innovations in Decentralized Pan-Orthoebolavirus Diagnostics — closes July 31, 2026
This one closes in days. The posted deadline is July 31, 2026, 11:30 a.m. PDT. If you are reading this at the end of July and do not already have a draft in the portal, treat this as a call to bookmark for the next cycle rather than a realistic target.
The Foundation anticipates funding a portfolio of up to 12 awards, sized to the scope of each use case, across five opportunity areas:
| Opportunity area | Funding range | Grant term |
|---|---|---|
| 1. Biomarkers | US$350–750K | 18–24 months |
| 2. Specimen Innovations | US$300–600K | 18–24 months |
| 3. Diagnostic Products | US$300–800K | 24–36 months |
| 4. Surveillance and early warning | US$300–600K | 24–36 months |
| 5. Quality and Implementation | US$150–400K | 18–24 months |
Eligible applicants include research institutes, nonprofit organizations, for-profit companies, international organizations, government agencies, and academic institutions. Applications must be in English and must comply with the Foundation’s global access requirements. Individuals classified as individuals for U.S. tax purposes are not eligible.
Applications go through the Gates Foundation portal at submit.gatesfoundation.org.
2. AI-Enabled Consumer Engagement to Advance Family Planning — closes August 25, 2026
This is the deadline the rest of this page is built around, because it is the nearest one you can still realistically write toward.
- Deadline: August 25, 2026, 11:30 a.m. PDT
- Award: up to US$500,000 per project
- Grant term: up to 12 months
- Applicant webinar: August 4, 2026, 7:00–8:00 a.m. US PDT (registration required; a recording is posted afterward)
The RFP welcomes nonprofit organizations, for-profit companies, international organizations, government agencies, and academic institutions, and it encourages multi-stakeholder collaborations. Individuals cannot apply.
There is a hard practical filter on this one that is easy to miss: applicants are expected to have existing consumer engagement infrastructure and an existing user base in one or more of Nigeria, Ethiopia, the Democratic Republic of Congo, Tanzania, Senegal, Niger, Kenya, South Africa, Zambia, or Côte d’Ivoire. This is not a call for a greenfield idea with no audience. If you cannot point to a channel and the people already on it, your proposal will struggle no matter how good the AI concept is.
3. Multiplex Platforms to Assess Indicators of Micronutrient Status, Inflammation and Infectious Disease — closes September 8, 2026
The furthest-out deadline of the three, and the one with the largest ceiling.
- Deadline: September 8, 2026, 11:30 a.m. PDT
- Alternative A (minimum scope): awards up to US$200,000 per project, grant term up to 12 months
- Alternative B (optimistic scope): awards up to US$800,000 per project, grant term up to 24 months, evaluated per project
- Applicant webinar: August 11, 2026, 7:00–8:00 a.m. US PDT
Eligibility mirrors the family planning call: nonprofits, for-profit companies, international organizations, government agencies, and academic institutions. Women-led applications and applications from low- and middle-income country institutions are particularly encouraged.
The two-alternative structure is worth reading closely. You are effectively being asked to scope your own ambition, and reviewers will judge whether the scope you picked matches the team and evidence you actually have.

Because calls rotate, always confirm the current list and the exact closing time on the official page before you commit weeks of writing. A page like this one is a starting point; the RFP document is the contract.
Who Should Apply (and Who Probably Should Not)
The door is open to a wide range of organizations, but not everyone is a good fit.
You are likely a strong match if:
You have a genuinely bold idea. A multiplex assay that collapses four separate lab tests into one low-cost platform. A diagnostic that works without a cold chain in an outbreak setting. “We want to expand our existing app to three more districts” is not bold enough.
You can tie your idea directly to one open RFP. Your proposal has to fit a specific named challenge clearly, not vaguely. A general global health concept mailed at the program will go nowhere.
You care about impact in low- and middle-income countries. Technology aimed at well-resourced urban hospitals is not what these calls are built for.
You can execute, not just theorize. A team with no lab access, no implementation partner, and no ethics plan will struggle. A small startup working with a district health office to trial a new antenatal tool is exactly the kind of partner these calls attract.
Who might not be a fit:
- Applicants with no connection to health or development outcomes.
- Projects that are pure theory with no concrete plan for testing.
- Teams that cannot show basic financial or ethical accountability.
- Individual applicants — the currently open RFPs require an organization.
Insider Tips for a Winning Application
1. Anchor your idea in a specific call, not a grand vision
Read the RFP document and phrase your idea using its language where the overlap is genuine. For the family planning call, that means naming the countries you already operate in, the channel you already run, and the users you already reach. For the multiplex call, it means stating which indicators your platform measures and at what cost per test.
Make it obvious that you read the call and designed the project for it.
2. Quantify “bold” and “high impact”
Everyone claims their work is bold. Reviewers have seen that word on thousands of PDFs. Show it instead:
- What is the order-of-magnitude difference you are aiming for? Ten times cheaper? Five times more people reached? Half the clinic visits?
- Why would a typical funder call this risky, and what reasoning lets you argue past that?
Spell out numerically what success looks like inside the grant term — which for the family planning call is only 12 months.
3. Match your plan to the actual grant term
These are short grants. The family planning RFP runs up to 12 months; the multiplex Alternative A is also 12 months. A plan that only pays off in year three is a mismatch.
A strong plan usually has:
- Two or three precise objectives
- Milestones with timing (“assay validated on banked samples by month 5; field usability study by month 10”)
- A short, realistic list of partners and sites
Country-wide rollouts in year one are a red flag. Show progression: idea → prototype → test → refine.
4. Put serious thought into ethics and community engagement
If your work touches human bodies, specimens, or intimate health decisions — and all three open calls do — reviewers want to see ethics approvals or a concrete plan and timeline for them, community partners rather than “subjects,” and sensitivity to power, gender, and cultural dynamics. An AI family planning proposal that says nothing about consent, data privacy, or misinformation risk will not survive review.
5. Make your budget tell the same story as your narrative
If the proposal is about assay development but the budget is 80 percent travel and conferences, you are sunk. Check that you are paying the right people at appropriate levels, budgeting realistically for lab work, translation, and local data collection, and leaving a modest cushion for plausible surprises. Reviewers spot fantasy budgets quickly.
6. Get non-specialist eyes on your draft
Reviewers come from varied disciplines. Ask someone from a related but different domain to read your summary. If they cannot quickly explain what problem you are solving, what you will do in the grant term, and how you will know if it worked, rewrite.
A Realistic Timeline to August 25, 2026
Working backward from the August 25, 2026 family planning deadline, with roughly four weeks to go:
Week of July 28: decide and download Pick your call. Download the RFP document, rules and guidelines, application instructions, budget template, and FAQs. Register on the submission portal now — do not discover on August 24 that your institution needs a new vendor ID. If you are targeting the multiplex call instead, you have two extra weeks; the same sequence applies, shifted.
August 4: attend the webinar The applicant webinar for the family planning RFP runs 7:00–8:00 a.m. US PDT on August 4, 2026. Register in advance and submit questions ahead of time. If you miss it live, watch the recording — these sessions routinely clarify scope questions that would otherwise cost you a rejection. The multiplex webinar is August 11, 2026, same hour.
First half of August: partners, design, and first full draft Confirm partners and get their roles in writing. Sketch the study or implementation design. Draft every narrative section — completeness first, polish later. Build the budget in the provided template rather than your own spreadsheet.
Third week of August: revisions, ethics, and attachments Use reviewer comments to tighten the logic and fix inconsistencies. Secure letters of support and any ethics documentation now, not in the final 48 hours. Confirm that budget figures in the narrative match the budget file exactly.
By August 23: submit Aim to submit at least 48 hours before the 11:30 a.m. PDT cutoff on August 25. That leaves room for portal problems, slow uploads, or a last-minute correction. Note that the deadline is a specific time in a specific time zone — convert it to your local time and write that on the wall.
Required Materials and How to Prepare Them
The exact checklist varies by call, and the RFP package is authoritative. Expect some version of:
- Project narrative. A jargon-light explanation of the problem, your approach, what you will do inside the grant term, and how you will measure success.
- Budget and budget justification. Use the provided budget template. For each category, add one or two sentences explaining why you need it and how you calculated it.
- Applicant and key personnel CVs. Short and focused on experience relevant to this project.
- Letters of support or collaboration. If you claim a district hospital, community organization, or university core facility as a partner, reviewers want a signed letter.
- Ethics or regulatory documents. Existing approvals, or a clear plan and timeline for obtaining them.
- Data, global access, and IP statements. The Foundation’s global access requirements are not boilerplate. Read them before you promise anything that conflicts with your institution’s policies.
Treat every attachment as another piece of the same story: this team can responsibly test a bold idea that could improve health outcomes.
What Makes an Application Stand Out
Scientific or technical merit. Is the underlying idea plausible? Are the methods appropriate for the question and the setting? Hand-waving technical descriptions do not survive.
Boldness and novelty. The best proposals make reviewers think, “if this works, it would change how we approach this problem.” A new assay format, a new delivery model, or a surprising combination of existing tools.
Impact potential and equity. Does this shift outcomes for communities that are usually last in line, or does it mostly serve people who are already well served?
Feasibility and team capacity. The right technical and contextual expertise, a plan that fits the grant term, and honest risk management — what could go wrong, and what you would do about it.
Common Mistakes to Avoid
Being vague about the “how.” “We will improve family planning through AI” is not a plan. Specify what, where, with whom, and on what timeline.
Overclaiming reach or speed. Promising to transform care for millions in 12 months on US$500,000 is not ambitious, it is naive. A well-designed pilot in two districts is more impressive than an empty promise of national change.
Ignoring context. Designs that assume perfect cold chain, stable electricity, and abundant staff are usually misaligned with the settings these calls target.
Treating communities as props rather than partners. In reproductive and sexual health especially, local agency matters. Proposals that read like outsiders experimenting on people lose credibility fast.
Missing an eligibility gate. Applying as an individual, or to the family planning call without an existing user base in one of the ten named countries, wastes weeks of work on a proposal that cannot be funded.
Frequently Asked Questions
Is there one Grand Challenges deadline each year? No. Each RFP sets its own deadline. Right now three are open with closing dates of July 31, August 25, and September 8, 2026. Check the official page rather than assuming a fixed annual round.
Is this only for big universities and major NGOs? No. Small organizations and early-career investigators are very much in the mix. What matters is a strong idea, a credible plan, and enough structure to manage funds responsibly. If you are small, highlight your agility and local ties, and name partners who fill the gaps.
Can individuals apply? Not to the currently open calls. The family planning RFP states that individuals cannot apply, and the diagnostics RFP excludes individuals classified as individuals for U.S. tax purposes. You need an institutional home.
Do I need preliminary data? It helps but is not always required. Bench results, simulations, or evidence from related interventions can substitute. With no data at all, your reasoning and design need to be especially crisp.
Is this only for low- and middle-income country applicants? No. Applicants can be based anywhere, but the impact focus is global development, and several calls explicitly encourage low- and middle-income country institutions and women-led teams.
Can I apply to more than one call? You can respond to multiple RFPs over time, but you generally submit one proposal per call. Check the rules and guidelines for the specific challenge.
What happens after I submit? Expect a review period of several months. You may get requests for clarification. If selected, you negotiate final budget and deliverables before the award is formalized.
How to Apply and What to Do Next
