Advanced Micro Devices‘ CEO Lisa Su shut down concerns over Big Tech’s elevated spending during an interview with CNBC’s “Squawk Box” on Wednesday and said investing in more computing will accelerate the pace of innovation.

“I don’t think it’s a big gamble,” she said. “I think it’s the right gamble.”

Many of AMD’s hyperscaler customers over the last 12 months have beefed up spending as the technology reaches an “inflection point” and companies can see the return on that spending, Su added.

Su’s comments come as tech’s megacaps announced more than $380 billion in AI spending in their latest earnings reports as the firms race to build out infrastructure to support soaring demand.

On Tuesday, Su told analysts that AMD expects revenues to grow 35% per year over the next three to five years due to “insatiable” AI chip demand.

Shares were last up more than 7%.

Concerns of a potential AI bubble have jolted markets in recent sessions as Wall Street raises concerns that valuations have gotten too high.
