The final weeks of summer are typically quiet on Wall Street. This year, a parade of initial public offerings expected after Labor Day is making a lot of noise.

Fund managers and analysts say their calendars are full of meetings with companies eager to gauge investor interest for upcoming offerings.

The U.S. IPO market is already on track for a record year after SpaceX raised $86 billion in its June offering. Artificial-intelligence giant Anthropic could raise even more in its expected offering, which is being teased to investors now alongside a bevy of smaller listings.

Smart-ring maker Oura-whose fitness-tracking devices are favorites of the finance set-is now weighing a September or October offering after having filed its paperwork in May, people familiar with the matter said. The company is expected to fetch a valuation well above the $11 billion valuation it fetched in a funding round last year, the people said.

Switch, which operates data centers, and SB Energy, which is backed by SoftBank and develops data centers as well as supplies power to them, are both meeting with investors in anticipation of offerings later this year, some of the people said. SB Energy in recent meetings highlighted its huge Ohio data center deal with OpenAI, an agreement the companies signed earlier this month after weeks of negotiations. Neo cloud company Nscale is also meeting with prospective investors, some of the people said.

Inspire Brands, a restaurant group with brands including Dunkin' and Arby's, is looking at an offering as early as the end of this year, though it could get pushed into early 2027, some people familiar with the matter say.

The recent choppy stock performance of comparable companies including Jersey Mike's-the popular sandwich chain that Blackstone took public in late July-might prompt Inspire to go public at a lower valuation than some of its investors had initially hoped. Inspire is backed by private-equity firm Roark Capital Group.

Oura, Switch, SB Energy, Nscale and Inspire are expected to collectively raise billions of dollars in their offerings. The IPO market is dependent on market conditions and there are no guarantees the companies will proceed as planned.

Traditional IPOs in the U.S. have raised $137 billion so far this year, according to Dealogic.

Anthropic, which could debut as soon as September or October, is expected to raise up to $100 billion, according to people familiar with the matter. Combined with the current IPO haul, the year will easily top the current IPO record raise of roughly $156 billion in 2021, according to Dealogic data.

SpaceX's historic offering in June went surprisingly smoothly despite its giant size, emboldening many companies to push forward with IPOs in the second-half of the year, according to people familiar with the matter. The fact that SpaceX's stock has since fallen below its IPO price and is now languishing at the level where it initially sold shares isn't deterring companies, their backers and their advisers from proceeding with offerings.

Investors say they haven't seen such a rush to public markets since 2021, when money flooded into newly listed companies ranging from Robinhood to Rivian. The fundraising bonanza in that year ended poorly for the majority of new issues. By the end of 2021, two-thirds of the companies that went public in the U.S. that year were trading below their IPO prices. They continue to languish; the class of 2021 IPOs still trade below IPO price on average.

This year's class of IPOs is faring better. Companies that went public in 2026 are trading up 21% on average from their IPO prices, according to Dealogic data.

Other companies could opt to hold their debuts until next year. Vantage Data Centers, a giant hyperscaler developer and operator backed by Silver Lake and DigitalBridge Group, is thinking about a 2027 offering, people familiar with the matter say.

OpenAI, Anthropic's chief rival, has been considering a 2026 listing, though some people familiar with the matter say it could be pushed until 2027. OpenAI recently told investors its revenue grew by 18% from the first to the second quarter while its losses deepened. At the same time, the company has told investors that its growth rate has picked up since the launch of a new set of models in July.
