Opera Surges 18% Following MiniPay Integration of Tether’s USDT Stablecoin

The evidence strongly and consistently supports the statement. The primary sources, which are official press releases from Opera and PR Newswire, confirm the foundational event that acted as the catalyst: the integration of Tether's USDT into the MiniPay wallet. Multiple independent and reputable secondary news sources then directly report on the market's reaction to this announcement. One highly relevant source from a reputable cryptocurrency publication, 'The Block', explicitly states that "Opera shares jump 18%" as a direct result of this news. Another financial news report, 'Stock Titan', corroborates this with a very similar figure, reporting a surge of "+17.3%". This minor variation is common in financial reporting of intraday stock movements and serves as strong independent confirmation of the event's magnitude. Another source, 'Crypto Briefing', also confirms that the stock price 'jumped' immediately following the announcement, reinforcing the direct causal link. There are no contradictions in the provided evidence. The primary sources establish the cause, and the secondary sources consistently report the effect, all linking the two events directly. The high level of agreement across multiple credible sources results in a high confidence assessment.
