Reddit’s high-flying stock run faces AI-training data test in earnings

Reddit Inc. shares have been on a tear since going public earlier this year, and the social-media company’s unique place in the artificial intelligence landscape will dictate whether the rally continues.

The stock is up 139 per cent since it began trading in March, the best performance among this year’s IPOs to raise at least $310 million, according to data compiled by Bloomberg. The next test of that rally will come with the Tuesday release of its third-quarter results.
