Tokenized stocks as collateral: what the October 14 unlock changes for investors in Germany

If you are holding a tokenized stock as collateral in a margin account, October 14, 2026 is a deadline for you, not a news item. At 6:00 a.m. New York time that day, the next lock-up tranche at chipmaker Cerebras comes free, covering up to around 19.4 million shares. The previous tranche of the same size was released on September 30. The share price closed 8.87 percent lower that day than the day before. An investor who merely holds the token sees a red number in the portfolio. An investor who has pledged it sees something else: a shrunken credit line, possibly in the middle of the night in Europe.

This article explains what actually happens to a pledged stock token on a date like this, which levers your provider pulls in the process, and which rules apply in Germany. The plain calendar with every Cerebras date through November is in our release schedule for the Cerebras lock-up. What follows is the mechanism behind it, which works the same way at every newly listed company.

What the Cerebras prospectus actually says about October 14, 2026

The source is not market chatter but the prospectus the company filed with the US Securities and Exchange Commission. It sets out a staged plan: 8.9 percent of the locked stock held by directors, officers, other employees and further existing shareholders comes free on each of three dates, September 30, October 14 and October 28, 2026, each at 6:00 a.m. New York time. Three smaller steps of 6.7 percent each preceded them in August and September. The document puts each of the three October steps at up to roughly 19.4 million shares.
