NYSE adds Broadridge, Computershare and Equiniti to its planned tokenized-stock market, firms it says serve almost 99% of the S&P 500

The New York Stock Exchange named four new partners on Monday for the tokenized-securities market it is planning, CoinDesk reported. Broadridge Financial Solutions, Computershare, Equiniti and Superstate join Securitize and tZERO, which had already signed agreements. According to the NYSE, Broadridge, Computershare and Equiniti together serve nearly 5,000 listed companies, including almost 99% of the S&P 500.

The three companies keep shareholder records, the ledger of who owns what, which gets harder to maintain once shares move between blockchain wallets and brokerage accounts. Broadridge said it will add onchain governance: smart contracts that tie tokenized shares to meeting agendas, voting rules and verified results, with investors voting through supported wallets, brokerage platforms or its ProxyVote system, according to CoinGape. It will also help NYSE-listed issuers tokenize their stock.

The platform would pair the NYSE's Pillar trading engine with blockchain settlement and custody. It would offer 24/7 trading, instant settlement and stablecoin funding, subject to regulatory approval. "Our priority remains protecting and upholding market integrity through every technological advancement," said Lynn Martin, president of NYSE Group.

CoinDesk notes that DTCC unveiled its own tokenization platform last week, focused on custody and transfers rather than trading, and that Nasdaq is building its own. It also says Equiniti is being acquired by Bullish, CoinDesk's parent company.
