More on the Anthropic IPO: our Anthropic IPO storyline page collects our pieces on it.
The email arrives before your first coffee: "Indicate your interest in the Anthropic IPO." Your broker wants a share count by next week. You've used Claude at work for a year and you think it's the best AI there is. The form has one empty box, and it's asking how much.
Everyone knows the outline. Anthropic is expected to start trading on Nasdaq as ANT around November 19. On Tuesday it set a price range of $70 to $78 a share for 825 million shares: about $58 billion to $64 billion, at a value of $1.26 trillion to $1.41 trillion fully diluted.
Here's why the day matters less than the price. Most investors don't get shares at the offer price. They buy once trading opens, when the most excited buyers set it. SpaceX, the giant June listing, closed its first day 19% above its $135 offer. On Thursday it closed at $139.94.
That gap is the real decision. In the famous IPOs below, first-day buyers typically saw 25% drops within six months. In a portfolio of a few million dollars, is your entry plan ready? A Trefis partner firm can review it in a free 30-minute call.
First day: first close vs the offer price in each prospectus. Six-month lows from Trefis closing prices, vs the first-day close; SpaceX's low so far was $108.27 on Aug 5. Median dip: 25%. Source: Trefis, prices through Nov 12.
The one that barely dipped, Google, was also far cheaper at its IPO: about 10 times its revenue over the prior 12 months, against 36 to 40 times for Anthropic. More famous IPOs and how their buyers did are in Which Of 10 Famous IPOs Made Buyers Rich? And the market around the listing moves too: on Tuesday, the day a hot October inflation report (+0.4%, the Labor Department said) came out, the Nasdaq-100 fund QQQ fell 0.7%.
Write the plan before the price exists. Say Anthropic should be 2% of a $3 million portfolio: $60,000. Split it into four.
A natural commitment price is the offer price itself: SpaceX, Facebook, Uber and Arm all closed below theirs within six months. Before you size anything, count the Anthropic you already own through Amazon and Google stock and your index funds.
This replaces the reactive move: a full position at the open. Watch three things: the final price, the float (the 825 million shares on offer are only about 6% of the shares outstanding after the IPO), and the lock-up dates. Some insiders can sell from the first trading day after pricing; more shares unlock on days 27, 48, 62 and 76, and bigger waves follow over the first year. The risk: if Anthropic is the next Google and never dips, your limit order never fills and you own three quarters of what you planned. That's what the first three steps are for.
We call it commit at a price, and get paid to wait. A price you choose in a quiet week is a plan; a price you chase at 10 a.m. on listing day is a reaction. Once ANT options list, a cash-secured put at your commitment price can even pay you a premium while you wait, though you must buy at that price if the stock falls below it.
