Cerebras Systems, CoreWeave and Broadcom block tokenized shares on OKXICE venue

• CoreWeave, Broadcom, and Cerebras Systems have all refused to permit tokenized versions of their stock on OKXICE’s new venue.
• The SEC’s Innovation Exemption, effective September 17, 2026, expires September 17, 2031 and lets venues trade tokenized stock without exchange registration if they notify issuers first.
• OKXICE filed notice on October 4 to list tokens tied to over 60 U.S.-listed companies, including Nvidia, Tesla, and Coinbase, but tokenization already dominates without company consent.

• $2.43B of tokenized stock issued without company permission versus $365 million with consent as of September 13.
• 84.5% of the tokenized stock segment consists of unauthorized third-party issuances, compared to barely 15.5% with issuer approval.
• 5 years duration of the SEC Innovation Exemption, running through September 17, 2031 before it expires.

The Securities and Exchange Commission created a five-year exemption on September 17 that allows permissioned blockchain venues to trade tokenized versions of U.S.-listed stocks without registering as exchanges, and liquidity providers to operate without dealer registration. The exemption gives companies a new right: they may block third-party-issued tokenized versions of their stock from trading on these venues by objecting within 30 days of written notice. CoreWeave (NASDAQ: CRWV), Broadcom (NASDAQ: AVGO), and AI chipmaker Cerebras Systems (NASDAQ: CBRS) have all exercised that right against OKXICE’s new trading platform, according to reporting by Cryptopolitan.

OKXICE filed notice on October 4 with intent to list tokens tied to more than 60 U.S.-listed companies, including Nvidia (NASDAQ: NVDA), Tesla (NASDAQ: TSLA), Apple (NASDAQ: AAPL), Microsoft (NASDAQ: MSFT), SpaceX, and crypto-focused firms such as Coinbase (NASDAQ: COIN), Circle (NYSE: CRCL), MicroStrategy (NASDAQ: MSTR), Robinhood (NASDAQ: HOOD), BitGo (NYSE: BTGO), and Securitize.

Each tokenized stock would trade against USDC, USDG, or Tether’s USDT, with the venue operating continuously across 24 hours. The exemption does not name the token issuer in its filing.

SEC Innovation Exemption creates opt-out right but leaves existing unauthorized tokens untouched

Under the Innovation Exemption, a tokenized securities venue must notify an issuer before making available for trading any tokenized NMS stock (U.S.-listed equities and exchange-traded products) that a third party has created. The company then has 30 days to object. If it remains silent, the venue may proceed. This represents a departure from traditional capital markets, where companies have no say over whether their shares trade on a national exchange.

The exemption’s conditions ensure tokenized versions provide shareholders the same rights and privileges as traditional stock, require smart contracts to be auditable and public on a permissionless ledger, and mandate that a venue halt trading in any tokenized stock when the underlying stock stops trading on its primary exchange.

The exemptions expire September 17, 2031, after which the SEC will assess whether permanent regulatory changes are warranted.

The opt-out right does not affect existing tokenized stock already circulating elsewhere, nor does it constrain offshore trading or the right of third parties to tokenize a company’s stock for any venue outside the exemption framework.

Unauthorized tokenization dominates market despite new company veto power

The refusals by CoreWeave, Broadcom, and Cerebras mask a deeper market reality: the vast majority of tokenized stock exists without issuer consent. As of September 13, approximately $2.43 billion worth of tokenized stock, 84.5 percent of the entire segment, had been issued by third parties without permission.

By contrast, tokens issued with company approval totaled only $365 million and had barely grown over the prior year.

Broker Robinhood lists more than 190 stock tokens, tracking prices of publicly traded companies as digital products. When AMC sent Robinhood a cease-and-desist order over an AMC-tied token, Robinhood refused to remove it.

This pattern reflects a regulatory gap: the Innovation Exemption applies only to centralized venues operating under its conditions, not to decentralized trading or existing off-chain products already in circulation.

An opt-out right at a single venue cannot stop third parties from tokenizing a company’s stock elsewhere or restrict tokens already trading on other platforms.

Computershare and law firms push for standing objection and public registry

Computershare, the transfer agent serving thousands of public companies, submitted a comment letter to the SEC on October 2 requesting that companies be allowed to file a standing objection covering all venues at once, rather than responding to each venue’s notice individually.

Computershare also called for a central, searchable public register listing which venues are seeking to list tokens and which companies have objected.

Law firm Hunton Andrews Kurth echoed those concerns in an October 8 letter, noting that crypto notification emails often land in spam filters, risking that issuers miss the 30-day window to object. Its clients are pushing for a framework requiring explicit company consent before tokenization, removal of any automatic approval deadline, and a public database specifying which tokens are prohibited.

These requests signal that institutional custody and transfer agents view the current opt-out mechanism as administratively fragile and insufficient.

The CCS read. The Innovation Exemption’s opt-out mechanism is procedurally sound but operationally weak. CoreWeave and Broadcom’s refusals show that capital-intensive, regulation-conscious firms will block third-party tokenization on compliant venues. But institutional investors should note that this does the opposite of what most market participants want: it leaves 84.5 percent of tokenized stock untouched because it resides on venues outside the exemption, and it creates a fragmented landscape where the same company can be tokenized freely elsewhere. The practical effect is to slow adoption on regulated venues while accelerating it offshore.

The SEC will accept public comment on the Innovation Exemption throughout its five-year term, with the agency explicitly inviting input on possible modifications and next steps. Whether regulators will adopt Computershare’s proposal for a standing objection and centralized registry, or whether corporate America will simply accept widespread third-party tokenization as inevitable, remains the critical open question shaping how tokenized equity markets will function through 2031.
