Crypto in 401(k) Plans: Final Rule Reaches White House, $10.8 Trillion at Stake

Some $10.8 trillion sits in American 401(k) plans, and Bitcoin is now one step closer to getting a slice of it. On Thursday, November 5, the US Labor Department sent its final rule on crypto in retirement plans to the White House for review, the last checkpoint before it can become official.

Key points:

• The Labor Department sent its final 401(k) rule to the White House on November 5. Once the review clears, the rule can be published and take effect.
• It would give employers a legal safe harbor if they follow a six-point checklist before adding crypto, private equity or real estate funds to a plan.
• No plan has to offer crypto. But with $10.8 trillion in 401(k) accounts, even a small shift could move serious money into Bitcoin.

One review stands between the rule and the Federal Register

The rule landed at the White House's Office of Information and Regulatory Affairs, the office that vets major regulations before they go public. The filing is listed as "Fiduciary Duties In Selecting Designated Investment Alternatives," with the identifier RIN 1210-AC38, and it is marked as a final rule and economically significant. The White House logged it on November 5, and there is no legal deadline forcing the review to finish by a set date.

That review is the last step in the process. If the White House clears it, the Labor Department can publish the final rule in the Federal Register and set the date it takes effect. The review can run up to 90 days, but the last version of this rule moved faster. The White House received the draft on January 13 and cleared it on March 24, about 70 days later, and the department put out its proposal a week after that.

One thing is still missing: The final text itself. The White House filing does not include it, so nobody outside the government knows yet whether the six-point checklist from the March proposal survived unchanged, how the final rule describes funds that hold digital assets, or when it will take effect. The Labor Department also said in its filing that it is still weighing the costs of the rule. So the filing is real progress, but it is not the finish line.

What the rule actually changes

At its heart, the rule is a shield for employers, not an order. It would give plan fiduciaries, the people who pick what goes on a 401(k) menu, a legal safe harbor under the Employee Retirement Income Security Act of 1974 if they follow a documented process when they add funds holding alternative assets. The March proposal laid out six factors they should weigh: performance, fees, liquidity, valuation, performance benchmarks and complexity. Meet those, and the employer gets protection from lawsuits over the choice. Skip them, and it does not.

The rule does not force a single plan to offer crypto, private equity or real estate. Each employer still picks its own menu. That is the part most headlines skip, and it matters. The rule only makes it safer for employers who want to offer these options. It changes the risk of saying yes, not the duty to say yes.

The road here has been long. In August 2025, President Donald Trump signed an executive order telling the Labor Department to rethink its retirement-plan guidance and, where it made sense, write rules with safe harbors for alternative assets. The department had already moved in May 2025, when it dropped Biden-era guidance that told plan managers to use extreme care before adding crypto, and went back to a neutral stance. The department put out its proposal on March 30, 2026, and published it in the Federal Register the next day. Thursday's filing is the final version of that same rule, now in White House hands.

The $10.8 trillion question

Americans held $10.8 trillion in 401(k) plans at the end of June, according to the Investment Company Institute. That number is why traders care about a rule that reads like dry paperwork. If even a small share of that money gets a crypto option, the flows could be large. Sweep, a crypto firm, posted on November 6 that moving just 2% of 401(k) money into crypto would mean about $216 billion in fresh inflows. That is the firm's own math, not an official forecast, and it assumes plans actually offer crypto and savers actually pick it. Still, it shows the scale people are talking about.

Bitcoin traded near $75,700 on Friday, down slightly on the day, after a rough week in which the price slipped under $75,000 and crypto funds saw heavy outflows. The 401(k) news did not lift the price on its own, and that fits the story. This is a slow-burn change, not a spark. The money would arrive plan by plan, menu by menu, over months and years, not in one trade.

My own read is simple: Watch the review clock, not the press releases. The filing is a step, not a finish line. What matters next is the final text, and whether it keeps the safe harbor intact.

Not everyone is cheering

The rule has its critics on Capitol Hill. Earlier this year, Senators Bernie Sanders and Elizabeth Warren pushed the Labor Department to scrap it, saying it would push savers into volatile assets like crypto. That push failed, but the worry behind it is real. Crypto prices swing hard, and retirement money is supposed to be the boring kind. A 401(k) that holds Bitcoin would still rise and fall with Bitcoin, safe harbor or not.

There is also a common mix-up worth clearing up. Some savers hear "crypto in 401(k)s" and think their plan will soon hold Bitcoin whether they like it or not. That is not how this works. The rule gives employers cover if they choose to add a crypto fund. It does not put crypto in anyone's account on its own. Your plan menu only changes if your employer decides to change it, and you still pick your own funds.

What to watch next

First, the White House review. It can run up to 90 days, and the last round took about 70. Second, the final text, once the Labor Department publishes it in the Federal Register. Read that text, not the headlines, because it will say whether the six-factor safe harbor survived and when the rule takes effect. Third, the first plan menus. Watch which big employers add a crypto option first, and what kind of fund they pick, because that will set the pattern the rest follow.

If you have a 401(k), do one simple thing now: Open your plan's menu and note what it offers today. That gives you a baseline. When the rule lands and your employer makes a move, you will be able to judge the change on facts, not on hype.
