Anthropic IPO in Japan: How to Apply via SBI and Rakuten

Based on SBI Securities’ press release of November 12, 2026 and Rakuten Securities’ notice updated November 11 (November 12, 2026). Dates are planned; check each broker’s official page before you apply. All times are Japan time.

Anthropic, the US AI company behind Claude (ticker: ANT), plans to list on Nasdaq on November 19 (US time). In Japan, SBI Securities and Rakuten Securities both opened IPO lottery orders (book-building) on November 11. If you win, you buy shares at the IPO price before trading starts.

The two brokers differ on deadlines and on which currency you can pay in. This guide lays out what you need to pick one, and, if you don’t have an account yet, how much a point site pays you for opening one.

What the brokers announced

SBI Securities said on November 4 that it planned to take orders, then confirmed on November 12 that orders were open, with an indicative price range of $70–78 per share. Rakuten Securities runs a dedicated notice page, updated on November 11 to say orders had started.

Both give the listing date as November 19 (planned). Rakuten adds that the listing will happen on some day between November 2026 and April 2027, so the schedule can still move.

SBI vs Rakuten: the differences

Both charge nothing and both accept NISA. The real differences are the deadline and the currency.

At Rakuten, orders go through the PC website only (the channel listed is “PC web”: log in, then US Stocks → IPO).

If you only hold yen and don’t want to convert, Rakuten is simpler. If you already bank with SBI Shinsei, the SBI lottery boost is worth a look.

Timeline: everything happens on Nov 19

SBI closes on the morning of the 18th; Rakuten closes at 2 a.m. on the 19th. Pricing, results, cancellations and the first trade all fall on the 19th.

Compiled from both brokers’ announcements (Japan time). The listing date and later times are planned.

How much money to prepare

The indicative range is $70–78 per share; the final IPO price is set on lottery day. News reports put that at roughly ¥12,000 per share.

Rakuten spells out what must be in your account by 2:00 on November 19:

Paying in yen

Shares × IPO price × FX rate × 1.05 (a 5% buffer for currency moves)

Paying in USD

Shares × IPO price

If short

You enter the lottery for as many shares as your funds cover

SBI settles in US dollars only, so convert your yen beforehand. Rakuten’s zero FX spread applies only to this IPO purchase; trading the shares in yen after listing costs the usual 25 sen per dollar.

Rakuten: a win means you buy

This catches out people used to Japanese IPOs. With a Japanese IPO you win first, then confirm the purchase. For this US IPO at Rakuten, your lottery order is already a purchase order. If you win, the trade goes through automatically.

If you just want a ticket in the draw, remember 12:59 on the 19th.

SBI: US dollars only, plus a lottery boost

SBI takes US dollars only this time. Easy if you already hold dollars; otherwise convert first.

SBI also gives better odds to customers whose SBI Shinsei Bank “SBI Hyper Deposit” (the account linked to SBI Securities) holds ¥100,000 or more. Its deadline is 10:59 on Wed Nov 18, more than half a day before Rakuten’s, so don’t mix them up.

No account yet? Compare point sites first

You need an SBI or Rakuten account to enter. Opening a Rakuten main account also opens the foreign securities account used for US stocks; at SBI you apply separately for a foreign stock account, which opens as soon as you submit. Both open as early as the next business day if you verify ID by photographing your My Number Card on a smartphone. Whether you make this deadline depends on the review, and if you miss it you can still buy after listing.

If you’re opening one anyway, going through a point site pays ¥10,000–25,000 in points. Brokerage accounts are among the best-paying point-site offers, but the amount varies a lot by site. These figures come from PointNavi, the point-site comparison tool we run:

Main brokerage account offers only (FX, CFD, kids’ accounts and iDeCo excluded), in yen. Hapitas’ ¥25,000 for Rakuten includes a bonus that ends Nov 23. PointNavi data from early November 2026; amounts change often.

PointNavi is run by may-money. It lists results as they are, even when the site we recommend isn’t on top.

Before you apply:

• One account per broker, one point site: if you’ve ever opened or applied for an account there, you don’t qualify.
• Read the condition: “open + deposit ¥50,000” offers need a deposit within the time limit. The money stays yours, so you can use it for the IPO or funds.
• Start from the point site’s button: going straight to the broker’s website earns nothing.

Before you apply

For reference, SpaceX (SPCX), listed in June, priced at $135 and opened at $150, about 11% higher, according to news reports. First-day gains on very large IPOs tend to be modest, and nobody knows how this one goes until listing day.

Japan’s tranche is part of a global offering, so pricing follows worldwide demand, which is not how Japanese book-building works. It’s worth skimming the prospectus linked from each broker’s page.
