The approval of spot Bitcoin ETFs in January 2024, followed by spot Ethereum ETFs in May 2024, established a new regulatory framework for cryptocurrency exchange-traded products in the United States. The SEC, after years of rejecting applications on the grounds of insufficient market surveillance and manipulation risk, ultimately accepted that large, well-surveilled spot markets with regulated custodians could support investment products that institutional and retail investors access through brokerage accounts.
That framework change has inevitable downstream implications. Once the regulatory logic for Bitcoin and Ethereum ETFs was established — based on the maturity of the underlying market, the availability of regulated custodians, and the capacity for surveillance-sharing agreements with regulated exchanges — the question of which assets come next became a matter of applying similar criteria rather than re-litigating first principles. Solana is the most prominent candidate, and the case for approval is meaningfully stronger than it was eighteen months ago.
The bear case for Solana ETF approval is not negligible — it rests on genuine regulatory questions that have not been fully resolved. But it has been weakening, not strengthening, as the Solana ecosystem has matured. An honest assessment requires engaging with both sides rather than settling for the assumption that ETF approval is either certain or impossible.
What the Bitcoin and Ethereum Precedents Actually Established
The SEC’s approval framework for Bitcoin and Ethereum ETFs was built on three pillars: the size and liquidity of the underlying spot market, the availability of regulated custodian solutions that can hold the asset for institutional products, and the existence of regulated derivative markets (futures) that enable surveillance-sharing agreements and market manipulation detection.
Bitcoin had CME Bitcoin futures trading at significant scale before the ETF approval, which allowed the SEC to lean on surveillance data from a regulated venue. Ethereum had CME Ethereum futures. The existence of those futures markets — and the associated CFTC oversight — was explicitly cited by the SEC as supporting the approval logic.
Solana’s CME futures product launched in March 2025, following the Bitcoin and Ethereum playbook directly. The launch was not accidental — it was specifically structured to create the futures market regulatory prerequisite that the SEC has used as part of its approval framework. CME SOL futures have grown in open interest and daily volume through 2025 and into 2026, reaching a scale that is meaningfully smaller than BTC or ETH futures but large enough to support the surveillance-sharing argument that the Bitcoin and Ethereum applicants used successfully.
The Custody Infrastructure Question
One of the legitimate concerns about early Solana ETF applications was custodial infrastructure. Regulated custodians — Coinbase Custody, BitGo, Fidelity Digital Assets, BNY Mellon Digital — had well-established institutional-grade custody for Bitcoin and Ethereum but less mature support for Solana, which requires different key management infrastructure given its account model and staking mechanics.
That gap has closed. Coinbase Custody added institutional Solana custody in 2024. Anchorage Digital, which holds a US national bank charter specifically for digital assets, supports institutional Solana custody. Fidelity Digital Assets has expanded its Solana infrastructure. The custody solution required for an ETF — cold storage of spot SOL by a regulated custodian on behalf of the fund — is available from multiple qualified providers with meaningful institutional track records.
The staking question is a separate and more complex issue. The institutional staking yield gap is a live question for Ethereum ETFs too — the SEC declined to include staking in the initial Ethereum ETF approvals, meaning Ethereum ETF holders do not earn staking yield. The same issue arises for Solana: SOL generates significant staking yield (roughly 6 to 8 percent annualised for validators), and an ETF that holds spot SOL without staking gives investors price exposure without yield. Whether future ETF structures can include staking is an ongoing regulatory discussion rather than a settled question.
The SEC’s Current Posture Under New Leadership
The regulatory environment for cryptocurrency at the SEC changed materially after the 2024 US election. The replacement of Gary Gensler with a chairman more explicitly receptive to crypto industry engagement shifted the SEC from an adversarial stance toward one where industry representatives report more substantive dialogue on product structures. Several pending crypto ETF applications that were stalled under the prior administration received more active engagement under the new leadership.
Solana ETF applications from VanEck, 21Shares, Canary Capital, and Bitwise were filed in late 2024 and early 2025. The SEC’s review timeline has been extended through the standard process, but applicants and their counsel have characterised the engagement as more substantive than prior cycles. The SEC has asked detailed questions about market structure, surveillance, custodial arrangements, and staking — all of which applicants interpret as engagement rather than resistance.
The political context matters in a way that is not ideal but is real: the current administration has taken a more explicitly supportive stance on crypto regulation than its predecessor, which creates a different incentive structure at the agency level. That political environment does not guarantee approval and should not be the primary basis for any investor’s assessment of SOL. But it is part of the factual context for understanding why approval odds have improved since 2023.
The Honest Objections That Have Not Been Resolved
The bear case for Solana ETF approval rests on several genuine concerns, some of which have been partially addressed and some of which remain active.
Market structure concerns: Solana’s spot trading volume, while substantial, is more concentrated on offshore exchanges (Binance, OKX) than Bitcoin or Ethereum were at the time of their ETF approvals. The proportion of Solana volume traded on regulated US venues — particularly Coinbase and Kraken — is lower than ideal for the surveillance-sharing framework the SEC has relied on. This is a real issue, though Solana’s US-venue volume has been increasing as regulated exchanges compete for SOL liquidity.
Validator concentration concerns: Solana’s proof-of-stake consensus relies on validators, and the stake distribution among validators is more concentrated than Ethereum’s. The top 20 validators control a meaningful portion of total staked SOL. This is relevant to regulatory assessments of market integrity and decentralisation, though it is worth noting that Bitcoin’s mining concentration — where a handful of mining pools account for most hash rate — did not prevent Bitcoin ETF approval.
Network reliability history: Solana experienced several significant network outages in 2021 and 2022, including outages lasting multiple hours. The network’s reliability has improved substantially in 2023, 2024, and 2025 — with no major outages during the period of highest institutional scrutiny — but the prior history remains part of the documented record that regulators consider. Solana’s local fee market improvements through SIMD-0096 have improved network economics and resilience, addressing some of the structural issues that contributed to prior congestion events.
What Institutional Demand Actually Looks Like
Institutional interest in Solana has been expressed through multiple channels that are distinct from retail ETF demand. Several hedge funds with established crypto allocations have built meaningful SOL positions. European crypto ETPs (exchange-traded products, which differ from US ETFs in structure) that track SOL have accumulated several hundred million dollars in assets under management, demonstrating that institutional-grade products tracking Solana can be operated without systemic issue.
Grayscale’s Solana Trust, which operates similarly to how GBTC operated before the Bitcoin ETF conversion, holds over $700 million in SOL as of early 2026 and has been one of the applicants for ETF conversion — following the same path that GBTC took to become a spot Bitcoin ETF. The GBTC-to-ETF conversion precedent is directly relevant: the same logic applied to Grayscale’s Bitcoin product (converting an existing trust to a spot ETF reduces friction and improves structure for investors) applies to Grayscale Solana Trust.
Whether institutional demand for SOL through an ETF vehicle would be comparable to the Bitcoin ETF flows is a separate question. Bitcoin ETF inflows were driven partly by the novelty of the product and partly by genuine institutional allocation decisions about Bitcoin as an asset class. Solana ETF inflows would depend on whether institutions view SOL as a distinct allocation worth dedicated exposure — rather than a higher-beta proxy accessible through other vehicles.
The Timeline and Probability Assessment
SEC decision deadlines on the current Solana ETF applications fall in mid-to-late 2026. Given the track record of extensions and the complexity of the applications, a decision before Q4 2026 is possible but not certain. The more likely scenario, based on how the Bitcoin and Ethereum approvals played out, is a final decision in late 2026 or early 2027, potentially with multiple applicants approved simultaneously rather than sequentially.
Probability assessments from prediction markets and crypto-focused research firms have moved from sub-20 percent in 2024 to 60 to 75 percent in mid-2026, reflecting the regulatory environment shift, CME futures launch, and improved custodial infrastructure. Those probabilities are not predictions — they are market consensus estimates under uncertainty — but the directional move reflects a genuine improvement in the regulatory landscape rather than purely speculative sentiment.
For investors evaluating SOL as an asset, the ETF approval is a potential catalyst but should not be the primary investment thesis. The asset’s utility and adoption — the Solana fee market economics, the DeFi and consumer application ecosystem, the developer activity — are the fundamental drivers of long-term value. The ETF is a distribution channel that expands the investor base. It is not a guarantee of appreciation, as the Ethereum ETF’s more modest inflows compared to Bitcoin’s demonstrated. Separating the ETF narrative from the asset thesis is important for making a sound investment decision rather than a narrative-driven one.
