Securitize began trading on the New York Stock Exchange Thursday under the ticker SECZ and simultaneously put its own newly listed common stock onchain, according to a press release the tokenization firm distributed via PR Newswire. Eligible U.S. investors can access tokenized SECZ through Securitize’s own regulated platform starting the same day.

The launch makes Securitize the first newly public company to bring its own stock onchain at the start of its life as a listed issuer, per the release. SECZ is expected to become the world’s largest tokenized stock at launch based on anticipated shareholder participation.

The shares began trading Thursday after Securitize completed its merger with Cantor Equity Partners, the SPAC vehicle that took the company public with roughly $400 million in proceeds. The Defiant previously reported shareholder approval of that deal, which made Securitize the first publicly traded tokenization company.

Tokenized SECZ will launch on Avalanche and Solana, the release states, giving the company a multichain footprint from its first day as a listed issuer. Access requires onboarding, KYC and AML checks, and confirmation of jurisdictional eligibility under U.S. securities law.

“We have long said that public equities are moving onchain, and there is no stronger validation of that belief than tokenizing our own public stock on Day 1,” Securitize co-founder and CEO Carlos Domingo said in the release. Domingo said tokenized SECZ represents the same common stock trading on the NYSE rather than a separate share class or a synthetic wrapper, and that tokenization changes the form of ownership without altering the underlying legal rights or transfer restrictions attached to the shares.

Securitize is the leader in real-world-asset tokenization by assets under management, with more than $4 billion tokenized as of June 2026 across funds run with asset managers including BlackRock, Apollo, KKR, BNY and Hamilton Lane. The company also holds a memorandum of understanding with the NYSE signed in March to help design transfer-agent and tokenization-agent standards for the exchange’s broader push into tokenized securities.

Domingo framed the self-tokenization as a template beyond Securitize itself. “Bringing SECZ onchain is not just a milestone for Securitize,” he said. “It is a blueprint for public companies that want to use tokenization to create more efficient, transparent and useful ownership experiences for their shareholders.”

Securitize expects tokenized SECZ to build a meaningful onchain shareholder base from day one, with additional functionality expected to develop over time, the release states.
