(Reuters) – Chipmaker Nvidia (NASDAQ:) has completed its acquisition of Israeli artificial intelligence company Run:ai, the startup said on Monday, following antitrust scrutiny over the buyout.

The European Commission gave unconditional approval to Nvidia’s $700 million bid for Run:ai, which helps developers optimize infrastructure for artificial intelligence, in early December, after saying in October that the deal would require EU approval in the field of competition protection.

The EU antitrust authority warned that the transaction threatens competition in the markets where the companies operate.

Its investigation into the transactions focused on practices that could strengthen Nvidia’s control over the market for graphics processing units (GPUs), which are sought-after chips often used in artificial intelligence tasks.

Nvidia dominates the AI ​​GPU market and holds approximately 80% of the market share.

However, the European Commission said earlier in December that the acquisition of Run:ai, initially announced in April, would not raise competitive concerns.

The U.S. Department of Justice is also investigating the chip giant’s buyout of Run:ai on antitrust grounds, as Politico reported in August.

Regulators on both sides of the Atlantic have recently stepped up scrutiny of startup takeovers by tech giants over concerns that such deals could shut down potential rivals.

The blog post said that Run:ai plans to make its software open source.

“While Run:ai currently only supports Nvidia GPUs, the open source software will enable it to expand its availability across the entire AI ecosystem,” it said.
