Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-04b62ea747e64610 quantitative
Shanghai opened a state-backed venue for trading data products in November 2021, listing 20 products across finance, transport and telecoms on its first day and signing 100 firms as registered 'data merchants'
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The launch report gives the date, 20 data products listed on day one across eight sectors, and 100 first-batch data merchants. The independent account confirms the 20 launch products and describes the first trade, in which a bank's Shanghai branch obtained grid-operator data.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. Xinhua — Shanghai Data Exchange inaugurated (25 Nov 2021)
  2. South China Morning Post — How to buy and sell data? Shanghai starts new exchange (25 Nov 2021)
Claim 2 clm-182126b5afb6d35c quantitative
Every listing carries a registration certificate under a one-product-one-code registry, and the Shanghai Data Regulations gave the market a legal basis from January 2022
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The launch report describes the data product registration certificate enabling one product, one code. The legal analysis records that the exchange is a quasi-government entity and that the Shanghai Data Regulation, effective 1 January 2022, implements the national personal-information, cybersecurity and data-security laws.
Caveat
The same analysis notes that the guidance does not resolve data ownership and publishes no operative pricing rules — the legal basis is for the venue, not for what is being sold.

  2. Cooley — Shanghai Data Exchange kicks off trading (legal analysis)
Claim 3 clm-00fc8a59b55baf2e quantitative
But China's earlier data exchanges, starting with Guiyang's in 2015, attracted little trade, and independent analysts still question whether these venues have real liquidity
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Two independent accounts record that the earlier Guiyang exchange saw few transactions and failed to take off, and one quotes an analyst calling the new venue 'still very experimental, and there are many foundational challenges to solve, including standardizing data valuations'. A later independent report quotes a researcher attributing the earlier failures to weak standards, data quality and low trust. On adoption, a later independent report gives a national figure: only 283 companies had registered data assets by the end of 2024, out of nearly 60 million registered firms. Against that, the venue's cross-border zone was still operating in 2025 with over 30 international data merchants and nearly 200 listed products — activity, but at a scale that leaves the liquidity question open.
Caveat
No claim-specific caveat recorded

Claim 4 clm-dc5f4d648ffbf8de quantitative
Over 2,700 data products listed between November 2021 and mid-2024, and RMB 1.16 billion in data-product transactions in 2023 — Shanghai municipal government figures, not independently audited
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The municipal statement is the carrying sentence: over 2,700 data products listed since November 2021 and 2023 data-product transaction value above RMB 1.16 billion. The state-owned assets regulator separately reports 2024 turnover past RMB 4 billion and over 4,500 listed products.
Caveat
All of it is operator-side reporting, not audited, and the entry labels it as such.

Sources carrying this claim

  1. Shanghai Municipal People's Government — first data-asset trading market begins trial operation at the SDE (29 Jun 2024)
  2. Shanghai Municipal State-owned Assets Supervision Commission — SDE 2024 turnover (25 Dec 2024)
