One solution is to use QMovie with GIF. I also tried using SVG (it's lightweight and offers support for transparency), but both QMovie and QImageReader don't seem to support animated SVG.

Model::Model(QObject* parent) : QFileSystemModel(parent)
{
    movie = new QMovie{ ":/resources/img/loading.gif" };
    movie->setCacheMode(QMovie::CacheAll);
    movie->start();

    connect(movie, &QMovie::frameChanged,
    [this] {
        dataChanged(index(0, 0), index(rowCount(), 0),
            QVector{QFileSystemModel::FileIconRole});
    });
}

QVariant Model::data(const QModelIndex& index, int role) const
{
    case QFileSystemModel::FileIconRole:
    {
        if (index.column() == 0) {
            auto const path = QString{ index.data(QFileSystemModel::FilePathRole).toString() };

            if (path.isBeingLoaded()){
                return movie->currentImage();
            }
        }
    }
}
