Global equity markets crossed a historic threshold this week, breaching $150 trillion in total market capitalization for the first time. The milestone reflects sustained investor optimism built on strong earnings, economic resilience, and confidence that AI-driven growth still has significant runway.

Much of the week's excitement centered on Anthropic, the company behind Claude, which took its first formal step toward going public by confidentially filing a draft S-1 with the SEC. Wall Street views Anthropic as one of the few private companies capable of graduating into the trillion-dollar tier, and its move to enter public markets is being read as a vote of confidence in the durability of AI demand.

The filing follows a period of explosive growth and a landmark funding round that placed Anthropic among the most valuable private companies in the world, with its revenue run rate surging dramatically over just the past year.

• Global stock market capitalization exceeded $150 trillion for the first time in history, setting a new all-time high.

• Anthropic confidentially filed an S-1 with the SEC, beginning the IPO process for what could become one of the largest public offerings in history.

• Anthropic was recently valued at $965 billion following a $65 billion funding round and grew its annualized revenue run rate from $10 billion to $47 billion in just one year.

For investors, the filing helped define the week: another sign that the AI boom may still be in its early stages. With a potential valuation approaching $1 trillion at listing, Anthropic's IPO would mark a milestone for leading model providers.

VSXY (+35.6%): A ticker change and turnaround optimism on comparable store sales turned heads this week.

PGR (+7.2%): The insurer passed State Farm as the largest automotive player while also awarding a special dividend to investors.

UNH (+5.1%): A dividend hike and improving cost trends helped boost investor confidence in the major insurer.

CELH (-15.4%): A formal investigation by the Texas Attorney General gives investors another regulatory risk around Celsius Holdings.

LULU (-12.9%): Shares fell after the company lowered its earnings outlook, raising concerns about slowing demand and margin pressure from competition.

CRWD (-8.2%): A strong quarter and exploding AI demand was not enough to hide the high valuation the cyber giant had accrued in it’s recent run.

The race to build better AI models increasingly depends on access to massive amounts of data. Over the past year, traffic from Meta's verified web crawler, Meta-External Agent, has risen sharply, while OpenAI's GPTBot has remained relatively stable. The gap widened significantly in early 2026, with Meta's crawler reaching record activity levels as the company continues investing heavily in AI infrastructure and model development.

For investors, the trend highlights how aggressively Meta is pursuing the resources needed to compete in the AI race. Large language models require enormous datasets, and rising crawler traffic can serve as a proxy for growing data acquisition efforts. While web-scraping activity does not directly measure AI training, Meta's rapid increase compared to OpenAI suggests the company is scaling its model training operations faster than the incumbent. As AI competition intensifies, access to high-quality training data may become one of the most important advantages in determining future market leadership.
