Why SOL Surged 44% and What the Supply Vote Means

Solana climbed to $110 on August 28 before settling near $106, putting the token up roughly 44% for the month and back above $100 for the first time since January, according to TradingView data. The move happened on the same day Solana validators closed a binding on-chain governance vote, the first in the network's history, on proposals that would permanently change how SOL is issued and destroyed.

On Kalshi, a prediction market platform, traders had already placed SOL's year-end price forecast at $125.50 as of August 28.

A wallet that had been dormant for two years also re-entered the market this week. According to Lookonchain, the address bought 95,928 SOL worth $9.74 million on August 27. Over three years the same wallet completed two SOL swing trades, each time buying at a low and selling at a high, producing a combined $4.95 million in profit.

What the governance vote actually decided

The vote ran through the Solana Governance Proposals system, or SGP, a new mechanism that lets validators and SOL delegators cast stake-weighted, binding votes on protocol changes. SGP was developed to address a persistent criticism of Solana's governance: that major decisions had historically been driven by the Solana Foundation and core developer teams with limited formal input from validators or the broader token-holding community. SIMD, which stands for Solana Improvement Document, is the technical proposal format the network uses. Earlier SIMDs passed through off-chain discussion and informal validator signaling rather than a binding vote.

Three proposals appeared on the epoch 1023 ballot. One ratified a Solana Constitution that formalizes the SGP voting process going forward. The two that moved the price debate were SIMD-550 and SIMD-553, each targeting SOL supply from a different direction.

SIMD-550, filed by engineers at Solana infrastructure firm Helius, would double the network's disinflation rate from 15% to 30% per year. Solana launched with an initial inflation rate of 8% per year, designed to decline by a fixed percentage annually until it reaches a long-term floor of 1.5%. Under the current schedule that floor arrives in 2032. SIMD-550 accelerates the timeline to 2029, which works out to approximately 18.9 million fewer SOL created over the next six years. The trade-off is staking yield. According to a 21Shares analysis, the change would reduce annual staking returns from roughly 5.25% today to about 2.25% within three years.

SIMD-553, developed by Solana research and development firm Temporal, targets the burn side. It splits the transaction fee into an inclusion fee paid to validators and a resource fee tied to computing demand, with the resource fee permanently destroyed. The change would raise daily SOL burns from approximately 650 SOL, worth around $48,000, to as much as 9,000 SOL, worth roughly $668,000, a jump of 12 to 14 times depending on network load. Both Solana client teams, Anza and Firedancer, completed code review for SIMD-553 on July 20. Each proposal required a two-thirds supermajority of participating stake to pass independently.

Why traders were already pricing the vote in advance

SOL's 14-day RSI sat near 84.5 on August 28, a level that puts the asset in technically overbought territory by conventional momentum metrics, where readings above 70 carry that label. The price ran from below $75 at the start of August to $110 intraday before the vote closed, a move traders attributed in part to anticipation of the supply-side changes.

The Solana Foundation has separately pushed the network's financial access case. At Solana Summit Serbia, Solflare's vidor said:

"Right now on Solana, you're able to trade stocks. You can buy Tesla stock, Amazon stock. You can buy gold, silver, Bitcoin. You get better FX rates on Solana than any bank, and better interest on platforms like Kamino than a deposit account." He added: "Right now, every one of you can do that with a mobile phone and an internet connection. Any financial instrument Wall Street was able to do, from your pocket."
