Crypto in Your 401(k): Solana and Dogecoin Could Qualify Under the New Rule — 5 Things to Know

Your 401(k) could soon hold Dogecoin. Not because the government endorsed the meme coin — but because the rule that would let crypto into America's retirement plans doesn't name a single coin, doesn't set a minimum market size, and leaves the door open to every altcoin that can pass six tests. The Labor Department sent the final version of that rule to the White House on November 5, 2026, and with $10.8 trillion sitting in 401(k) accounts, the question is no longer whether crypto gets in — it's which coins make the cut first.

What Just Happened: The Rule's Long Road to the White House

The story starts on August 7, 2025, when President Donald Trump signed the executive order "Democratizing Access to Alternative Assets for 401(k) Investors," directing the Labor Department to reexamine the rules keeping alternative assets out of most retirement plans. The department unveiled its proposal on March 30, 2026, the comment period closed on June 1, and on November 5, 2026, it sent the final rule to OIRA — titled "Fiduciary Duties In Selecting Designated Investment Alternatives" (RIN 1210-AC38), logged as a final, economically significant rule with no legal deadline for review.

In May 2025, the department had already rescinded Biden-era guidance urging fiduciaries to exercise "extreme care" before adding crypto — language that effectively warned employers away. The new rule goes further: it would give plan fiduciaries a legal safe harbor under the Employee Retirement Income Security Act (ERISA) when they follow a documented process for choosing investments, including funds holding alternative assets. The safe harbor is the point. Employers stayed away from crypto largely because they feared being sued for offering a volatile asset; a documented, defensible process turns "too risky to touch" into "we can justify this."

The scale explains why the industry is watching so closely. Americans held approximately $10.8 trillion in 401(k) assets as of June 30, 2026. A scenario shared by the firm Sweep and cited in coverage of the rule suggests that even a 2% allocation across those plans would represent roughly $216 billion flowing toward crypto. That number is a scenario, not a forecast — no plan is required to offer crypto, and most will move slowly. But it frames the stakes: this is the largest pool of retirement money in the world, and the gate is opening.

The 6 Tests Every Coin Must Pass

The March proposal does not list approved cryptocurrencies, and it sets no minimum market capitalization. Instead, it tells plan fiduciaries to weigh six factors when choosing any investment — crypto or otherwise: performance, fees, liquidity, valuation, benchmarks, and complexity. Here is what each one means in practice for a coin trying to get into your 401(k).

• Performance history matters most: a coin needs a track record a plan committee can point to. Bitcoin's 17-year history and Ether's decade-long run give committees something to document; a token launched last year has almost nothing to show.
• Fees must be defensible in court: excessive-fee lawsuits are the most common way 401(k) plans get sued, so cheap, plain-vanilla exposure wins over exotic, high-fee structures.
• Liquidity must be deep and daily: a plan needs to buy and sell at fair prices every business day, including on bad days. Thinly traded tokens that gap 10% on a single sell order fail immediately.
• Valuation must be transparent and reliable: the plan needs a price it can trust every day. This is the test that quietly decides almost everything, as explained below.
• Benchmarks must exist to measure against: a committee needs an index or reference point to judge whether the investment did its job. Coins with regulated index products and futures markets have them; most altcoins do not.
• Complexity must be explainable to ordinary savers: if a plan committee cannot explain what the asset is to a 45-year-old engineer saving for retirement, it should not be on the menu.

The most important of the six is valuation. Bernardo Brites, co-founder and CEO of Trace Finance, told Cointelegraph that a practical test would be whether a plan committee can document a daily, reliable price from a regulated product. That single sentence draws the line between the coins that can enter a 401(k) in 2027 and the coins that cannot: a regulated spot ETF, a CME futures contract, or a listed index product gives a committee a price from a regulated market, while a token trading only on offshore exchanges does not.

The Qualification Scorecard: Which Altcoins Actually Pass?

Apply the six tests honestly and a clear pecking order emerges. The table below scores the major candidates on what matters most to a plan committee — regulated price, liquidity, track record, and benchmarks. The verdicts are assessments based on the rule's published criteria and expert commentary, not guarantees: the final rule text is not public yet, and every plan decides for itself.

Coin	Regulated price source	Market cap (Nov 6)	Track record	Verdict
Bitcoin (BTC)	Spot ETFs, CME futures	~$1.5 trillion	Since 2009	Passes clearly — first in line
Ethereum (ETH)	Spot ETFs, CME futures	~$273 billion	Since 2015	Passes — second in line
Solana (SOL)	Spot ETF, Grayscale index ETF	Large-cap	Since 2020	Likely — strongest altcoin case
XRP	Spot ETFs since January 2026	Large-cap	Since 2012	Likely — legal clarity helps
Cardano (ADA)	Grayscale index ETF only	Mid-cap	Since 2017	Possible — thin regulated footprint
Dogecoin (DOGE)	Futures, no US spot ETF	Mid-cap	Since 2013	Unlikely soon — benchmark gap

Bitcoin and Ether are the consensus first movers. Teresa Goody Guillén, managing partner at Bellementis PLLC, said Bitcoin and Ether are likely to be first because they have established markets and investment products, while other cryptocurrencies are not automatically excluded — but plan managers would need to show their choices are sensible. Brites agreed that Bitcoin passes the proposed checks clearly and Ether also passes, while other tokens may fail on track record or benchmarks.

Solana and XRP sit in the next tier, and both got a meaningful boost this month. On November 7, the SEC approved the conversion of the Grayscale Digital Large Cap Fund into an ETF, clearing a five-coin basket — Bitcoin, Ethereum, XRP, Solana, and Cardano — for spot trading, with weights of roughly 80% Bitcoin, 11% Ethereum, 4.8% XRP, 2.8% Solana, and 0.8% Cardano. XRP spot ETFs were separately approved in January 2026 and began trading on January 10. Each approval hands a plan committee exactly what Brites described: a daily, reliable price from a regulated product. That is why the Grayscale decision matters far beyond the $775 million in that one fund's assets — it quietly built the regulated-price infrastructure five different coins need to pass the 401(k) test.

Dogecoin is the interesting edge case. It has a longer history than Solana, deep liquidity, and enormous name recognition — but no US spot ETF, no CME futures contract, and no widely used benchmark index, the exact things the six-factor test rewards. A plan committee trying to document a daily reliable price from a regulated product would struggle to do it for DOGE today. That does not mean Dogecoin is excluded forever. It means its path into a 401(k) runs through a regulated product first — an ETF approval, a futures listing, or an index inclusion — and that product does not exist yet.

Why ETFs Will Come Before Direct Holdings

Almost every expert expects the same sequence: funds and ETFs first, direct coin holdings much later, if ever. The reason is plumbing, not philosophy. An ETF slots into the custody and recordkeeping systems 401(k) administrators already use, trades on a regulated exchange, and publishes a daily net asset value. Direct holdings would raise extra concerns about storage, cybersecurity, and pricing — and while Guillén noted those risks should not automatically rule out direct holdings, they make the fiduciary's job far harder.

Brites expects adoption in stages: existing brokerage options first, then standalone ETFs and funds with small crypto holdings. The first crypto option in a typical 401(k) is most likely a diversified fund — a target-date fund or a managed allocation fund with a small crypto sleeve — rather than a menu line that says "Bitcoin" next to the S&P 500 index fund. The Investment Company Institute, which supports the rule, has pointed the same way.

For anyone who already holds crypto outside retirement accounts, the distinction matters differently: a 401(k) will probably never be the best vehicle for direct ownership of specific coins — you cannot hold your own keys inside an employer plan. What the rule changes is access for the millions of savers who will never open an exchange account.

The Timeline: When Could Your 401(k) Actually Offer Crypto?

The rule is not in effect yet. OIRA review can take up to 90 days, with no legal deadline. Publication follows, and a rule typically takes effect about 60 days after that. Brites expects some crypto options in 2027, ETFs at larger employers later that year, and wider availability by 2028. The table below lays out the sequence as experts expect it — expectations, not confirmed dates.

Step	When	What happens
OIRA review	Nov 5, 2026 – up to 90 days	White House review of the final rule; text still not public
Publication	Early 2027 (expected)	Final rule published in the Federal Register
Effective date	~60 days after publication	Safe harbor becomes available to plan fiduciaries
First crypto options	2027	Brokerage windows and diversified funds add crypto sleeves
ETFs at large employers	Late 2027	Standalone crypto ETFs appear on big-plan menus
Wider availability	2028	Mid-size plans follow once the legal dust settles

Three things could stretch that timeline. OIRA could send the rule back with changes. Litigation is likely: the safe harbor's weight in court is unsettled, and Brites warned it would give plan managers some protection from lawsuits but would not stop them being sued. And a future administration could reverse the rule entirely — another risk Brites flagged, and one that could make employers hesitant to build long-term plans around it. None of these block the rule. All of them explain why most employers will wait for someone else to go first.

What Most People Get Wrong About Crypto in 401(k)s

The coverage of this rule has produced a handful of confident claims that do not survive contact with the actual text. Here are five of them, corrected.

• The myth that every plan must offer crypto: the rule requires nothing. It creates a safe harbor for fiduciaries who follow a documented process. An employer can read the final rule, shrug, and change nothing — and most will, at least at first.
• The myth that the government picked the winners: the rule names no coins and sets no minimum market cap. The market decides which coins qualify, through regulated products, liquidity, and track records — not through a government list.
• The myth that your 401(k) will hold actual Dogecoin: the first products will almost certainly be funds and ETFs, not direct coin holdings. The coins inside those funds still have to pass the six tests.
• The myth that the safe harbor ends lawsuits: it does not. It gives fiduciaries a documented process to defend themselves with. They can still be sued, and the safe harbor's legal weight is untested in court.
• The myth that this is only about Bitcoin: Bitcoin will be first, but the rule's silence on which coins qualify is the whole story. The same six tests that admit Bitcoin create a defined path for Solana, XRP, and eventually other altcoins — each gated by whether a regulated price exists.

What This Means for Your Retirement Money

If you are saving for retirement, the question is what to do between now and 2028, when crypto options become common. Three moves make sense today.

First, check what your plan already offers. Some 401(k) plans provide a brokerage window with crypto-adjacent exposure, and a growing number offer crypto ETFs in their brokerage tiers. You may have more access than you think — or none at all, which tells you how your employer is likely to treat the new rule.

Second, do not wait for your employer if retirement crypto exposure matters to you. An IRA already allows crypto exposure today through spot Bitcoin and Ethereum ETFs, and our guide to adding Bitcoin to a retirement account walks through the mechanics. The trade-off is contribution limits: IRAs cap annual contributions far below 401(k) limits, so the 401(k) channel matters most for meaningful allocations.

Third, think in percentages, not coins. The $216 billion scenario assumes a 2% allocation — a small slice of a portfolio, not a bet-the-retirement wager. Bitcoin traded near $76,000 on November 7, roughly 40% below its all-time high of $126,156, after a week in which hot jobs data pushed December rate-hike odds toward 80% and ETF outflows topped $869 million. That volatility is why the allocation conversation starts at 1–5%. If you are weighing how much crypto belongs in a long-term plan, our analysis of how much Bitcoin you actually need to retire puts the numbers in honest perspective.

The Risks Nobody Should Skip

The opportunity is real, but so are the risks — and the rule itself creates a new one. A future administration could reverse it, leaving employers that built crypto menus around the safe harbor exposed. Litigation risk cuts both ways: employers fear being sued for offering crypto, and for the fees on the crypto products they offer. The safe harbor helps with the first fear and does nothing about the second.

Volatility remains the fundamental risk. A 40% drawdown from an all-time high is not an anomaly for Bitcoin — it is a normal feature of the asset, and it is exactly what a plan committee must be able to explain to a saver nearing retirement. Fees are the quieter risk: crypto ETFs charge more than plain index funds, and in a 401(k) every fee is a potential lawsuit. And concentration risk deserves a mention too: the Grayscale basket that just won approval is roughly 80% Bitcoin, so even "diversified" crypto exposure is still mostly a Bitcoin bet.

None of this is an argument against the rule. It is the argument for the rule's design: six documented tests, a safe harbor for fiduciaries who do the work, and no mandate for anyone. The coins that pass will have earned their place through regulated markets and real track records.

Frequently Asked Questions

Can my 401(k) hold Dogecoin now?

Not through the new rule — it is not in effect yet, and Dogecoin currently lacks the regulated price source (a US spot ETF or futures contract) that plan committees need to document a daily reliable price. DOGE would need a regulated product first before a plan could justify offering it.

Which cryptocurrencies could be in a 401(k) first?

Bitcoin and Ethereum are expected first because they have spot ETFs, CME futures, deep liquidity, and long track records. Solana and XRP are the most likely next candidates — both now sit inside regulated ETF products after the SEC approved the Grayscale five-coin ETF conversion.

When will crypto actually appear in 401(k) plans?

Experts expect some crypto investment options in 2027, ETFs at larger employers later that year, and wider availability by 2028. The final rule must first clear White House review (up to 90 days from November 5, 2026), be published, and take effect — typically about 60 days after publication.

Does the rule force my employer to offer crypto?

No. The rule creates a legal safe harbor for plan fiduciaries who follow a documented process when adding alternative investments. It does not require any plan to offer crypto, private equity, or real estate. Your employer decides.

How much money could flow into crypto from 401(k)s?

Americans held about $10.8 trillion in 401(k) assets as of June 30, 2026. A scenario cited in coverage of the rule suggests a 2% allocation would represent roughly $216 billion. That is a scenario, not a forecast — actual flows depend on how many employers offer crypto and how many savers choose it.

Is the rule final?

Not yet. The Labor Department sent the final rule to OIRA on November 5, 2026. The final text has not been released, review has no strict deadline, the rule could still change, and a future administration could reverse it.

Conclusion

The most important sentence in the Labor Department's 401(k) rule is the one that is not there. No list of approved coins. No minimum market cap. No favorites. Just six tests and a safe harbor for the employers willing to apply them. That silence is what makes this rule bigger than a Bitcoin story: a standing invitation to every altcoin with a regulated price and a real track record — and a standing challenge to every coin without one.

Bitcoin and Ether will walk through the door first, in 2027, most likely inside funds and ETFs rather than as direct holdings. Solana and XRP are next in line, armed with the regulated products the rule rewards. Dogecoin waits outside — not banned, not excluded, but missing the benchmark and the regulated price that the six tests demand. Whether your 401(k) ever holds any of them depends on your employer, your plan, and a rule that still has to survive White House review. But the direction is now set: retirement money is coming to crypto, and the coins that prepared for it will be the ones that get in. For the full background, read our earlier report on the $216 billion that could flow into crypto from 401(k) plans, and compare the ETF options in our guide to the best Ethereum ETFs of 2026.
