happy monday, AI family, and welcome back to AI Valley.

here are the biggest things worth knowing today:

  • Anthropic files for its IPO

  • Plus trending AI tools, posts, and resources

Let’s dive into the Valley of AI…

VIKTOR

My name is Viktor. I'm the AI employee your whole company shares, and 70,000+ teams have hired me.

Finance asks for last month's revenue by plan, pulled from Stripe and matched against the books. Sales asks me to clean up stale deals in HubSpot and nudge each owner. Marketing wants to know which Google Ads campaigns burned budget last week. Engineering hands me a pull request to review. Ops asks for a way to track vendor contracts and gets a web app at a live link.

Each team teaches me how it works, and I remember. I work inside the 3,200+ tools you connect and hand back the finished thing. Anything I can't undo waits for a person to approve it. SOC 2 certified.

Give me one request from every team this week.

THROUGH THE VALLEY

3/ Anthropic is going public, and it could be the biggest IPO ever. The Claude maker has officially filed for its IPO under the ticker ANT, potentially listing on November 9th. There's talk of raising $100B at a whopping $2T valuation, which would beat SpaceX's recent $86B IPO record. Anthropic hasn't confirmed either number. (Not bad for a company founded five years ago)

Its financials are even wilder. It made $16.3B in the first half of 2026, up from $1.2B a year earlier, or roughly $6.6M in revenue per employee. It also reported an $80.7B net loss, although $72.4B of that was largely noncash accounting charges tied to its rising valuation. The operating loss was closer to $693M.

What I'm curious about is how public investors will price a company growing this quickly while committing hundreds of billions to compute. At a $1.5T valuation, they're paying roughly 46 times annualized first-half revenue. That's a pretty enormous bet that AI demand, and Anthropic's share of it, will keep growing for years.

And with OpenAI still private, Anthropic could become Wall Street's first proper test of what a frontier AI lab is actually worth.

3/ Kimi K3.1 Pro is giving the big AI labs something to worry about. Moonshot's new 2.8T-parameter model ranks fourth on Artificial Analysis, ahead of GPT-6 Astra and Anthropic's Fable 5.1, and competes with Opus 5.5 on several benchmarks. Pretty remarkable for a Chinese model whose weights are expected on November 4.

One example caught my attention: teams of five Kimi and Opus 5.5 agents were given the same video-making task. Kimi finished in 26 minutes for $7.31. Opus took two hours and cost $76.42. That's roughly 10x cheaper and nearly 5x faster on that particular task. I'd like to see how consistently it performs across other projects, but those numbers are hard to ignore.

API pricing starts at $2/$10 per million input/output tokens, although Kimi reportedly consumes more tokens than some rivals. There's also a Highspeed version that's 2–3x faster.

The bigger story might be what happens when the weights drop. If a model this competitive can be downloaded and run independently, proprietary labs have another reason to justify their premium pricing. Being slightly better on benchmarks won't be enough for every customer.
