Rule Breakers recommendation PubMatic (NASDAQ:PUBM) fell over 24% after the market closed, as the forecast for the coming quarter disappointed investors despite second-quarter revenue and adjusted earnings beating previous guidance.

• Q3 revenue guidance of $63.5 million, 10.8% below expectations: Fool analyst Alicia Alfiere commented that "3Q guidance was a disappointment for some investors, as the company forecasted revenues to fall at least 3% (that's excluding last year's political ad revenues), due to macro uncertainty and platform issues for a top DSP client."
• "We are building for what we believe will be one of the largest market shifts our industry has seen in years." CEO Rajeev Goel highlighted new artificial intelligence (AI)-powered products with platform expansion, another reason he believes the long-term trajectory of the company is bright. Alicia notes that Goel thinks "AI is blurring the line between demand- and supply-side platforms and that his company could be well positioned to grow as a result."

Tesla (NASDAQ:TSLA) CEO Elon Musk has attacked Apple (NASDAQ:AAPL), claiming the App Store favors OpenAI on the chart leaderboards, as he seeks to enhance the market share of his xAI company.

• "An unequivocal antitrust violation": Musk confirmed that he will be taking immediate legal action against Apple, saying they were playing politics by not highlighting his products relative to competitors.
• "OpenAI will just stay focused on making great products." Apple and OpenAI have a partnership around AI built into the latest iPhones, but any special treatment was downplayed by OpenAI CEO Sam Altman in a reply to Musk.

Chinese authorities have sent notices to a range of companies, discouraging them from using Nvidia's (NASDAQ:NVDA) H20 chips, despite President Donald Trump confirming a 90-day extension of the pause on additional tariffs.

• Concern around location-tracking and remote shutdown capabilities: The guidance was particularly focused on any use for government-related purposes by either state or private businesses, given fears around chip usage.
• New tariff pause increases odds of physical meeting: The extension means headline rates of 30% for Chinese imports and 10% on U.S. exports will continue, but the November deadline means more time for trade teams to meet.

Rule Breakers rec CAVA (NYSE:CAVA) is set to report quarterly earnings after the closing bell, with expectations of a strong 23% rise in revenue, building on the rapid growth from last quarter.

• Two of 2025's largest initial public offerings: CoreWeave (NASDAQ:CRWV) will release results following the market close, with investors focused on the size of AI capex spend. Circle (NYSE:CRCL) will report ahead of the opening bell, with the stablecoin and blockchain company expected to post a Q2 loss.
• Higher inflation could put pressure on future rate cuts: Consumer Price Index inflation data is expected to rise from 2.7% in June to 2.8% for July, with the impact of higher tariffs likely to start feeding through to price-level data.
