Why the share keeps falling
The Foundation is winding the program down on purpose. Since April 2025 it removes three long-standing validators for every new one it admits, and it now describes the program as an incubator rather than ongoing support. Vote-cost cover tapers over a validator's first year — 100% for three months, then 75%, 50%, 25% — and stops entirely after twelve. The share therefore falls from two directions at once: SFDP delegates less, and the rest of the network stakes more.
What the program actually does
SFDP delegates Foundation-held SOL to validators that meet published criteria on performance, decentralisation and data-centre concentration, and covers part of their vote costs while they establish themselves. It was how a large part of Solana's validator set got off the ground. It was never meant to be permanent, and the criteria tighten over time — from May 2026, no more than 15% of a data-centre provider's validators may be stake-qualified.
What this changes when you pick a validator
A validator carrying a lot of SFDP stake is carrying stake with an expiry date. When it is withdrawn the operator keeps the same costs — roughly a SOL a day in vote fees alone — against a smaller stake, which is the point at which commissions tend to rise. Before delegating, it is worth knowing whether an operator stands on its own delegations or on the program: the live validator ranking compares operators on commission and performance, and the guide to choosing a validator covers what else to look at.

FAQ
Can I tell from this chart whether my validator relies on SFDP?
No — this series is network-wide and does not break down by validator. It tells you how large the program still is and which way it is going, not who inside it depends on it. For a specific operator, judge it the way you would judge any other: commission, uptime, and whether it has meaningful delegations that are not the Foundation's.
Should I avoid a validator that has SFDP stake?
Not by itself — meeting the criteria is a signal in its own right. What matters is proportion. An operator whose stake is mostly SFDP loses most of its stake when the delegation ends, while its costs stay put, and that is when commissions rise. An operator with substantial delegations of its own does not have that problem.
Where does this data come from?
It is aggregated from on-chain Solana stake account state per epoch, in SOL: stake delegated through the program against total delegated stake. The denominator lags the SFDP figure by about two days upstream, so the most recent days carry no share value and are left out of the average rather than counted as zero.
