Trade Desk Crashes 17%, Datadog Down 18%: Ad Tech Is Cracking

Some earnings seasons have a theme. This one's theme, at least for Thursday night, was expensive software meeting reality. $TTD and $DDOG both reported after the bell, and both got punished in ways that should make growth investors sit down and take a breath.

Trade Desk reported Q2 revenue of $715 million, missing the street's $750 million estimate. Fine, misses happen. But the real gut punch was Q3 guidance of at least $650 million, landing roughly $158 million below the $808 million analysts were penciling in. The stock dropped 17%, which in Trade Desk terms is not a rounding error. The bull case has always been that programmatic advertising is structurally growing and TTD sits at the center of it. The bear case, now looking a lot louder, is that when budgets get squeezed in a macro uncertainty environment, advertising dollars are the first to go. The Iran conflict driving oil prices and inflation fears back into the conversation is not a great backdrop for ad spend confidence.

Datadog had its own rough night. Shares fell roughly 18%, erasing approximately $18 billion in market cap, after adjusted gross margin came in below average analyst estimates. The revenue headline numbers were decent, which makes the margin miss sting more. DDOG trades at a premium because investors are paying for compounding efficiency, not just growth. When that efficiency story wobbles, the valuation math gets uncomfortable fast.

Meanwhile, over on the winners' podium: $SOUN (SoundHound AI) popped 10% after reporting record revenue of $62 million and raising full-year guidance to $230-$260 million. The CNBC coverage highlighted a $1 trillion addressable market for enterprise agentic AI by 2030. Seeking Alpha's quant system is flagging it as a strong sell on the basis that net margins are sitting at -91.84% and GAAP losses keep widening. Two very legitimate opinions, completely incompatible. That is what early-stage AI investing looks like right now.

The YouTube sentiment split tells the whole story. Investor's Business Daily flagged the upcoming earnings for $AMAT and $LITE as setups with massive binary outcomes, noting that beat-and-raise is already priced into AMAT while LITE carries triple-digit EPS growth expectations of 237%. The bar keeps getting raised, and one stumble means a 17% overnight. The macro backdrop, with oil near $83 and inflation fears creeping back in, is not exactly forgiving for companies that need to justify 30x sales multiples every single quarter.

In an earnings season where the consumer names and energy plays are printing, the message from ad tech and observability software is simple: the multiple was the risk all along.
