Anthropic’s lock-up can last a year for some shareholders

Deep Dive: Anthropic’s Lock-Up Runs Up to a Year, in Stages

Anthropic filed its registration statement on Form S-1 on Monday and applied to list its Class A shares on Nasdaq under the symbol ANT. The filing leaves the share count and price range blank but lays out a staggered lock-up. As reported, different groups of existing shareholders become eligible to sell at different points, from the first day of trading to as long as 365 days after the IPO. Business Insider counted 23 release dates in the first year, against fewer than 10 for SpaceX.

For investors who hold exposure through a fund, special purpose vehicle or contract, that schedule may answer only part of the liquidity question. Their ability to sell an interest, receive shares or collect a payment also depends on the terms of the particular vehicle through which they invested.

Employees, founders and larger holders are on separate calendars

According to Business Insider’s reading of the S-1, non-founder directors, officers and certain current and former employees and consultants may sell up to 10% of their locked-up shares on the first day of trading. TokenPost reports that another 35% becomes eligible two full trading days after Anthropic publishes full-year 2026 results, and the remainder on the earlier of two trading days after first-quarter 2027 results or 180 days after the IPO.

The seven co-founders face a longer lock-up. Both outlets report that up to 29% of their locked-up shares may become eligible around the 180-day mark. The rest stays restricted for up to a year: TokenPost gives the end date as the earlier of two trading days after third-quarter 2027 results or 365 days after the IPO. Larger holders and other stockholders have separate schedules.

Goldman Sachs and Morgan Stanley, the lead underwriters, may release holders early. The registration statement is not yet effective, and eligibility to sell does not mean a holder will sell.

SpaceX’s lock-up, in Quartz’s account of its S-1, combined earnings-tied releases with five time-based tranches of 7% each, plus an extra 10% if the stock traded at least 30% above the offering price. Business Insider describes Anthropic’s schedule as date-based only. The two companies differ in shareholder base, offering structure and disclosure, so the schedules are not directly comparable. Further, the performance of one company is not a reflection or prediction of the performance of the other, and past performance is not an indicator of future performance.

Fund investors hold interests in a vehicle

A lock-up or market standoff agreement binds the shareholders who signed it or whose plans contain it. As the Pulse noted on Tuesday, a standoff may be written into option plans and investor agreements, reaching holders who never signed an underwriter’s lock-up. The scope depends on the applicable agreements and plans.

When a fund or special purpose vehicle is the holder of record for Anthropic shares, the lock-up applies at that level. The people who invested in that vehicle own units or interests under a separate set of documents. Those documents, together with the vehicle’s own lock-up, may set when an investor can redeem, receive shares or sell the interest. The cited coverage does not establish when investors in any particular vehicle can access liquidity. That depends on the vehicle’s documents.

Funds have their own calendars. Fundrise, which runs the NYSE-listed Innovation Fund (VCX), moved the lock-up expiration for investors who bought shares before the fund’s public listing from Sept. 14 to Aug. 13. That change let those investors sell a month earlier, independent of any portfolio company’s schedule.

Distributions add another step. When Valor Equity Partners gave its limited partners about 8.5% of its SpaceX holdings in kind in September, per Bloomberg, each LP could decide whether to sell or hold based on its own tax position and timetable, subject to any applicable restrictions. Lock-ups commonly require recipients of transferred shares to accept the same restrictions, though that depends on the agreement.

Contracts have separate payment terms

Some exposure to private companies comes through contracts rather than shares. Ondo Finance’s private-company notes, described in the Pulse in October for a different, unnamed company, are unsecured obligations of an issuing vehicle. Per Ondo’s FAQ, payment is tied to events that include a public listing followed by six months of trading. Ordinary funding rounds, employee tenders and secondary share sales do not qualify. The noteholder’s claim is against the issuer, and the note’s terms set when payment is due.

Transfers of the underlying shares are a separate question. In May, OpenAI warned that unauthorized transactions could violate securities laws and invalidate the underlying equity, CoinDesk reported.

Some vehicle terms may track the company’s lock-up

The reported schedule addresses directors, officers, employees and founders directly. A vehicle’s documents may also mirror the issuer’s lock-up, and sponsors may coordinate distributions or sales with the underwriters. Separate documents do not necessarily mean a longer wait for liquidity.

The filing is not final and the IPO is not guaranteed. An amended S-1 may fill in the share count and price range and change the lock-up terms. For investors in a vehicle, the documents to read alongside it are the terms governing transfers, redemptions and distributions.

Manual

Holder of record

A holder of record is the person or entity whose name appears on the issuer’s books as the owner of a share. Investors may hold shares through a brokerage account or own interests in a fund or special purpose vehicle that holds the shares. The applicable lock-up, plan and vehicle documents determine which restrictions reach each investor.
