Investors are demanding tighter valuation discipline, and a string of high‑profile companies have responded by postponing, cancelling or reworking their initial public offerings (IPOs) in 2026. The trend underscores lingering uncertainty in global equity markets.

Australia’s AI data‑centre operator

Firmus, an Nvidia‑backed AI data‑centre operator, withdrew its planned listing on the Australian bourse in October. The company had been targeting a valuation of about $30.6 billion. Firmus said it will seek private‑market funding and keep alternative listing options under review.

US brokerage Clear Street

Wall Street brokerage Clear Street pulled its planned U.S. IPO in February after first delaying the deal and sharply cutting its fundraising target. The firm cited market conditions as the reason for not proceeding.

Smart‑ring maker Oura

Finland‑based Oura postponed its planned U.S. IPO in September, pointing to uncertainty in market conditions. The company had hoped to raise up to $2.2 billion, which could have valued it at as much as $15 billion.

Nuclear equipment maker Holtec Nuclear

Holtec Nuclear, based in Camden, New Jersey, withdrew its planned U.S. IPO in September. The company initially postponed the offering, citing adverse sentiment affecting both equity markets and the nuclear sector.

Home‑owners insurer Bamboo Insurance Services

Bamboo Insurance Services postponed its U.S. IPO in late September. The insurer had set a target price range of $18‑$20 per share for 35 million shares, which would have raised up to $700 million and valued the company at more than $3 billion.

Advanced materials maker Amaero

Amaero delayed its planned U.S. IPO in September after initially seeking to raise capital through the sale of 7.5 million shares.

Franco‑German defence group KNDS

KNDS, the maker of the Leopard 2 tank and Caesar howitzer, put its planned stock‑market listing on hold in July, shelving what would have been one of Europe’s largest defence IPOs. Sources said the company could have been valued at around €15 billion (approximately $16.8 billion).

CopperTech Metals

CopperTech Metals delayed its U.S. IPO in late June, citing volatility across the global copper equity sector. The firm had planned to raise $423.5 million by offering 23.5 million shares priced between $16 and $18 each, targeting a valuation of up to $3.57 billion.

Indian fintech PhonePe

Walmart‑backed Indian fintech PhonePe paused its IPO plans in mid‑March, pointing to geopolitical tensions and volatility in global capital markets. The company was aiming for a valuation between $9 billion and $10.5 billion.

These postponements and cancellations illustrate the cautious stance investors are taking toward large‑scale equity offerings amid ongoing market volatility. Companies are turning to private funding routes or waiting for more stable conditions before returning to public markets.
