Lobbying disclosures for the first quarter of 2019 show a wide swath of industries and advocacy groups focusing on financial technology issues, including the Association of National Advertisers, Intuit, Mastercard, Alibaba, FreedomWorks, IBM, the Entertainment Software Association and U.S. Public Interest Research Group.

More than half of the 80 firms that reported lobbying on fintech in the first quarter listed blockchain and cryptocurrencies, including tax elements of the latter, among their biggest concerns. Combined, more than 80 firms lobbying on fintech reported spending more than $42 million in the first quarter of 2019.

The data doesn’t perfectly capture fintech lobbying. The U.S. Chamber of Commerce, for example, accounted for $16.4 million of the $42 million, but the chamber’s lobbying spending also covers many non-fintech issues, such as trade, infrastructure, drug pricing and health care.

The data show the Blockchain Association, a trade group, spending $100,000 itself and another $60,000 through the S-3 Group, a government relations and public affairs firm. And Coin Center, a cryptocurrency advocacy group, spent $140,000 in the first quarter for both in-house lobbying and outside lobbying by RWC Inc. and the Sternhell Group.
