Meta builds Facebook, Instagram, WhatsApp, Messenger and Threads, apps that billions of people use to message friends, share photos and video, and follow creators and businesses. Most of its revenue comes from advertising: businesses buy placements across these apps, and Meta's AI systems decide who sees each ad and report the results. Its Meta Superintelligence Labs group builds the company's own AI models, the Meta AI assistant and the Muse agent app. Its Reality Labs unit makes Quest headsets and, with eyewear maker EssilorLuxottica, Ray-Ban and Oakley smart glasses. Meta was founded as Facebook in 2004 and is based in Menlo Park, California.

Simplify's Take

What believers are saying

  • A booming ad business backs pay and stock: Meta's revenue rose 28% to $60.8 billion in the June 2026 quarter.
  • AI engineers get vast resources: Meta expects $130 billion to $145 billion of capital spending in 2026.
  • Wearables teams are scaling: in February 2026, Meta sought to double glasses output to 20 million units this year.

What critics are saying

  • Job security is shaky: about 8,000 employees were hit by Meta's May 2026 layoffs, aimed at funding its AI push.
  • Meta's biggest apps still face a breakup fight: the FTC appealed its Instagram and WhatsApp court win in January 2026.
  • Hardware plans get reshuffled: Meta cut about 1,500 Reality Labs jobs in January 2026, shifting from the metaverse to wearables.

What makes Meta unique

  • Meta's four apps form one huge audience: 3.56 billion people used them daily in March 2026.
  • Meta leads smart glasses through eyewear giant EssilorLuxottica: their Ray-Ban and Oakley models sold over 7 million pairs in 2025.
  • Meta builds consumer AI agents in-house: its Muse app, launched September 2026, topped Apple's US free-app chart within ten days.

Meta launches Waddle World, an AI Tamagotchi-style pet app, in the Philippines

Meta has launched Waddle World, an AI-powered virtual pet app that resembles a Tamagotchi. It is available in the Philippines on iOS and Android, and was spotted by social media consultant Matt Navarra. Users hatch a pixel pet, feed it, and play with it in a 16-bit world. The app also works as a journal: users describe their day by voice or text, and the pet writes an entry with a doodle. It offers mini-games and can send a weekly email based on what it learned about the user. Meta says the app is not a chatbot or a habit builder, and has no streaks or scores. It is rated for users over 18. The launch may be a test, or a precursor to a Tamagotchi-like gadget powered by Muse.

Nvidia's $3B Meta stake fuels circular AI economy fears as Meta seeks $95B

Nvidia is buying $3 billion of shares in Meta, one of its biggest customers, as Meta moves to raise up to $95 billion in equity to fund its AI spending. Nvidia, AMD and Broadcom have agreed to buy as much as $5 billion of the shares between them. Nigel Green, chief executive officer of deVere Group, called it a sign of a "circular AI economy" in which chipmakers buy shares in the companies that buy their chips. "Sooner or later, someone outside the circle has to pick up the bill," he said. Meta will start with $35 billion of underwritten offerings, followed by a $60 billion at-the-market sale from early 2027. Its projected 2026 capital expenditure is $135 billion to $145 billion. Nvidia put $100 billion into OpenAI in 2025 and has joined 121 funding rounds this year, up from 13 in 2022.

Instagram launches Apple TV app as Meta chases YouTube's 13.5% share of US TV viewing

Instagram, owned by Meta Platforms, has quietly launched an app for Apple TV, MacRumors reported. Release data dates it to October 23, with no press release or launch event. The app plays Reels, longer videos and live shows, and requires tvOS 26.0 or later. It follows rollouts on Amazon Fire TV, Google TV and Samsung smart TVs. Instagram head Adam Mosseri said in October 2025 that if viewing is moving to TV, "then we need to move to TV too." YouTube took 13.5% of US TV viewing in June, against 7.9% for Netflix, according to Nielsen's Gauge. Meta's third-quarter revenue rose 26% to $64.6 billion, while user growth slowed to 3%. No Roku app has been reported.

Meta stock is 18% off its high: AI agents and $65B in quarterly revenue make the dip a buy

Meta Platforms shares sit about 18% below their September high of $779.82 and are slightly down for the year, despite a strong third quarter. At about $650, the stock trades at 21.5 times 2026 earnings estimates. Revenue rose 26% to nearly $65 billion, beating management's guidance. Ad impressions grew 10% and the average price per ad climbed 14%, helped by AI upgrades to its ad models. More than 10 million people downloaded Muse, Meta's new personal AI agent, in its first six weeks. Meta's apps reach 3.6 billion people daily. Operating profit fell 37% after a one-time $9.9 billion legal charge. Excluding it, operating income rose 11% to about $22.9 billion. Meta plans $135 billion to $145 billion in capital spending for 2026, which has weighed on the shares.
