Abaxx probe request tests Canada's market oversight

Abaxx Technologies Inc. has asked Canadian market regulators to examine possible manipulative trading in its shares and hired Paul Weiss to help answer a short-selling campaign by Viceroy Research. Bloomberg reported that shares of the Toronto-based market infrastructure company have fallen 25 per cent since June 10, leaving it with a market capitalisation of about C$1.3 billion ($920 million).

The request takes what might have remained a valuation fight and puts it in front of market watchdogs. Abaxx is still contesting Viceroy’s case, but it is also asking whether trading around the report looked like ordinary price discovery or something that deserved closer surveillance. For a company built around market infrastructure, the answer matters beyond the share price.

That is a difficult allegation to prove. Public short campaigns are lawful, and a target can dispute a report’s conclusions without showing the market around it was manipulated. Abaxx’s argument is narrower: look at the timing, the trade patterns and the mechanics of the repricing, not only at whether investors believed Viceroy.

Abaxx described Viceroy’s allegations as “false and defamatory”, according to Bloomberg, and said it had retained Paul Weiss as it prepared its response. The legal hire gives the company a more formal route for rebutting the report. The request to regulators adds a second route, one that asks authorities to decide whether the selling around the campaign crossed a line they should police.

Viceroy has framed the matter as a standard short thesis. Bloomberg said the firm described Abaxx’s valuation as “sustained by management incentives”, not as a price move created by improper trading. Crypto Briefing reported that Viceroy disclosed its short position on June 11 and that Abaxx shares dropped 13.8 per cent after the initial report. Those dates give regulators a starting ledger: the disclosure, the immediate stock reaction and the trading that followed.

Why the dispute reaches beyond one stock

The company draws extra attention because it sits close to market plumbing, not simply a single product cycle. That does not shield Abaxx from bearish research. It does raise the stakes when management says an attack has implications for confidence in disclosure and trading integrity around a listed market operator. Crypto Briefing also reported that Abaxx secured C$69 million in financing in May, a sign it had recently been telling investors there was still capital support before the short campaign gathered force.

Short campaigns often settle into a familiar exchange: management says the report is unfair, while the short seller says it has exposed weak fundamentals. This one now has a surveillance question attached. If regulators act, the focus moves to the mechanics of the selloff as well as the speech around it. If they do not, Abaxx will still have to persuade investors that its rebuttal is stronger than Viceroy’s claims.

The next phase is likely to turn on evidence rather than rhetoric. Abaxx will need to show that its complaint rests on more than anger at a falling share price. Viceroy, meanwhile, will need its thesis to hold up as the company and its lawyers answer in more detail.

For Canadian markets, the episode is a reminder that activist short selling can become a test of disclosure rules, trade surveillance and confidence in supervision itself.
