With Mayor Eric Adams facing a five-count federal indictment and at least four Democratic primary challengers next year, the quarterly fund-raising reporting deadline on Friday carried heightened intrigue.

Would Mr. Adams see a significant drop-off in donations? And of the candidates seeking to replace him, who would make the most of the mayor’s problems?

The answers were only partially revealed on Friday, with Mr. Adams’s fund-raising disclosures not reported by the New York City Campaign Finance Board by day’s end.

It was not clear if the mayor’s campaign filed disclosures at or past the deadline, or not at all. Vito Pitta, a compliance lawyer for the Adams campaign, did not respond to requests for comment.

As for Mr. Adams’s Democratic rivals, Brad Lander, the city comptroller, claimed bragging rights by bringing his fund-raising total to just under a million dollars for his mayoral campaign so far. It was enough to potentially qualify him to receive $3.5 million in taxpayer money under the city’s matching funds program, which awards candidates $8 for every dollar up to the first $250 donated by a city resident.

Mr. Lander said he was in a “strong position” to qualify for the maximum amount allowed in matching funds, enabling him to hit the $7.93 million spending cap for a primary or special election, should Mr. Adams resign or be forced out. Mr. Lander also raised the most money in the three-month reporting period that ended Oct. 7, collecting just over $315,000.
