Announcing Filecoin ProPGF Batch 3: General Track

We're excited to announce Filecoin Public Goods Funding (ProPGF) Batch 3 - General Track, a $2M milestone-based funding round dedicated to two areas where the ecosystem has the clearest, highest-leverage needs:

1. Maintaining the core infrastructure the network depends on
2. Delivering against published Requests for Proposals (RFPs) that support working group structures called, “pods,” each focused on product-market fit (PMF) exploration in key verticals –– including Web3 Builders and Web2 Object Storage.

Building on the work of Batch 1 and Batch 2, this round sharpens our focus. The ProPGF team has learned a lot about where funding creates the most durable impact, and Batch 3 channels that learning into a tighter, more intentional program - one designed to give the teams keeping Filecoin healthy and the teams building alongside Pods the support they need to do their best work.

Applications will open on filpgf.io on May 26, 2026.

What Batch 3 Funds

Batch 3 supports two categories of work:

1. Core Infrastructure Maintenance

Funding for the foundational work that keeps the protocol reliable, performant, and safe, including the implementations, critical libraries, dependencies, and essential services that the rest of the ecosystem uses.

2. RFP Responses: Pod-Supporting Work

Funding for projects submitted in response to specific RFPs that will be published on filpgf.io and Filecoin.io the week of May 26, 2026. These RFPs cover support and innovation work in service of pods.

Funding Model: Milestone-Based

All grants under this program are milestone-based. Detailed funding parameters and the full evaluation framework will be shared on filpgf.io

Key Dates

1. Applications Open: May 26, 2026
2. Early Bird Deadline: June 9, 2026. This is simply the cut-off for a June review. Projects submitted by this date will be reviewed in June with decisions targeted for the end of the month. "Early bird" doesn't mean priority funding, a higher chance of approval, or any advantage in the review itself. It only means an earlier review and feedback.
3. Final Application Deadline: June 16, 2026
4. All Funding Decisions Shared: by mid-July 2026

Selection Committee

The selection committee will incorporate some changes to reflect Batch 3's focus. More details on the updated composition will be available once the applications open.
